Stroke is the fifth leading cause of death in the United States and the leading cause of long-term disability. Every 40 seconds, someone in the U.S. has a stroke — and every 3.5 minutes, someone dies from one. For nurses, stroke care is defined by urgency: roughly 1.9 million neurons are lost for every minute a large-vessel ischemic stroke goes untreated. Whether you work in the ED, on a neuro floor, or in the ICU, you will care for stroke patients, and the speed and quality of your assessments directly affect outcomes.

Ischemic vs hemorrhagic stroke: key differences
| Feature | Ischemic stroke | Hemorrhagic stroke | TIA (warning event) |
|---|---|---|---|
| Mechanism | Arterial occlusion (thrombus or embolus) | Vessel rupture — blood into brain tissue or subarachnoid space | Temporary occlusion with spontaneous resolution |
| Proportion of strokes | ~87% | ~13% (10% ICH, 3% SAH) | Not counted as stroke — warning event |
| Classic presentation | Sudden hemiparesis, aphasia, facial droop; may stutter over hours (thrombotic) | Sudden onset; severe headache, vomiting, rapid LOC decline (ICH); "thunderclap" headache (SAH) | Sudden neurological deficit resolving fully within 24 h (most within 1 h) |
| CT appearance | Often normal in first 6–12 h; hypodense area develops later | Hyperdense (bright white) immediately visible | Normal CT |
| Primary treatment | IV thrombolysis within 4.5 h; mechanical thrombectomy for large-vessel occlusion | BP reduction, anticoagulation reversal, possible surgical evacuation | Urgent workup; antiplatelet therapy; risk factor control |
| tPA administration | Yes — if criteria met and hemorrhage excluded | Absolutely contraindicated | Not applicable |
| 30-day mortality | ~10–15% | ~30–50% (ICH); ~30–40% (SAH) | <1% (but 10–15% stroke risk within 90 days) |
| Key nursing priority | Establish LKW time; BP to <185/110 for tPA eligibility | Reverse anticoagulation; aggressive BP control; ICP monitoring | Urgent neurology referral; monitor for completed stroke |
Pathophysiology: what is happening in the brain
Ischemic stroke: the penumbra and ischemic cascade
Ischemic stroke begins when blood flow to a region of the brain is interrupted by arterial occlusion. Within seconds of flow cessation, neurons in the core infarct zone lose their ATP supply. Membrane ion pumps fail, sodium and calcium flood into cells, and irreversible cell death begins within minutes.
Surrounding this core is the ischemic penumbra — tissue that is hypoperfused and electrically silent but structurally intact. Penumbral cells survive for hours when some collateral flow persists. The entire rationale for rapid reperfusion therapy is to rescue this penumbra before it converts to infarcted tissue. This is what “time is brain” means at the cellular level.
The ischemic cascade unfolds in sequence:
- Failure of ion pumps → cellular depolarization, excitotoxic glutamate release
- Calcium influx → activation of destructive enzymes (proteases, lipases, nucleases)
- Mitochondrial dysfunction → free radical production, oxidative stress
- Inflammatory cascade → cytokine release, leukocyte infiltration
- Cerebral edema → peaks at 3–5 days post-infarct; major cause of secondary injury
Three main mechanisms cause ischemic stroke:
- Thrombotic stroke. A thrombus forms at an atherosclerotic plaque within a cerebral artery, progressively narrowing and occluding the vessel. Large-vessel thrombosis typically involves the internal carotid or middle cerebral arteries. Symptoms may stutter over hours as the clot builds.
- Embolic stroke. A clot or debris forms elsewhere (most commonly the left atrium in atrial fibrillation) and travels to the cerebral vasculature. Onset is abrupt. Embolic strokes carry higher risk of hemorrhagic transformation because when the embolus fragments and flow returns, damaged vessel walls may bleed.
- Lacunar infarct. Occlusion of a single small perforating artery due to chronic hypertension-related lipohyalinosis. These produce small (<1.5 cm) deep infarcts in the basal ganglia, thalamus, internal capsule, or pons. Prognosis is generally better than large-vessel strokes.
Hemorrhagic stroke: hemorrhage expansion and secondary injury
Hemorrhagic stroke results from rupture of a cerebral blood vessel. The bleeding causes direct tissue destruction, and the expanding hematoma raises intracranial pressure, compresses adjacent structures, and can cause herniation.
- Intracerebral hemorrhage (ICH). Rupture of a small artery within the brain parenchyma, most commonly from hypertension-related Charcot-Bouchard microaneurysms. Common locations: basal ganglia, thalamus, pons, cerebellum. ICH accounts for ~10% of strokes but carries 30–50% 30-day mortality. Hematoma expansion occurs in roughly 30% of patients within the first 3 hours — the strongest predictor of early deterioration.
- Subarachnoid hemorrhage (SAH). Bleeding into the subarachnoid space, most often from rupture of a berry aneurysm at the circle of Willis. Classic presentation: sudden “thunderclap” headache described as the worst headache of the patient’s life, with nuchal rigidity, photophobia, and rapid LOC decline. SAH’s unique complication is vasospasm, which peaks at days 4–14 after the initial bleed.
Stroke recognition: FAST, BE-FAST, and stroke mimics
The FAST mnemonic is the most widely taught prehospital and nursing stroke screen. BE-FAST adds two components that capture posterior circulation strokes, which FAST alone misses.
BE-FAST stroke screen
B — Balance. Sudden loss of balance or coordination, trouble walking, dizziness.
E — Eyes. Sudden vision changes — blurred or double vision, visual field loss.
F — Face drooping. Ask the patient to smile. Is one side drooping or numb?
A — Arm weakness. Ask the patient to raise both arms. Does one drift downward?
S — Speech difficulty. Ask the patient to repeat a simple sentence. Is it slurred or garbled?
T — Time to call 911. Note the time symptoms began. Activate the stroke team immediately. Last-known-well time drives every treatment decision that follows.
The B and E additions matter because posterior circulation strokes (vertebrobasilar territory) present with vertigo, ataxia, diplopia, and visual field cuts rather than classic hemiparesis. Posterior strokes account for roughly 20% of ischemic strokes and are frequently missed when only FAST is used.
Stroke mimics to rule out first: Hypoglycemia is the most critical — check a fingerstick glucose immediately on every suspected stroke patient. Other mimics include Todd’s paralysis (post-seizure focal deficit), complex migraine, Bell’s palsy, and hypertensive encephalopathy. BE-FAST positive findings initiate the stroke alert; they do not confirm stroke.
NIH Stroke Scale (NIHSS): what it measures and how to use it
The NIHSS is a systematic, quantitative tool for measuring stroke-related neurological deficit. You will use it at admission, at regular intervals throughout the acute phase, and before and after any intervention. Changes over time tell you whether the patient is improving, stable, or deteriorating, and they guide treatment decisions.
NIHSS assessment items
| Item | What it tests | Score range |
|---|---|---|
| 1a. Level of consciousness | Alertness: awake, drowsy, stuporous, comatose | 0–3 |
| 1b. LOC questions | Orientation: current month and patient's age | 0–2 |
| 1c. LOC commands | Follow commands: "blink your eyes," "squeeze and release my hand" | 0–2 |
| 2. Best gaze | Horizontal eye movements: can the patient track to both sides? | 0–2 |
| 3. Visual fields | Test all four quadrants; identify hemianopia or quadrantanopia | 0–3 |
| 4. Facial palsy | Symmetry of facial movement: show teeth, raise eyebrows | 0–3 |
| 5. Motor — arms | Arm drift: hold at 90° (sitting) or 45° (supine) for 10 seconds. Score each arm separately. | 0–4 each |
| 6. Motor — legs | Leg drift: hold at 30° supine for 5 seconds. Score each leg separately. | 0–4 each |
| 7. Limb ataxia | Coordination: finger-nose-finger and heel-shin tests | 0–2 |
| 8. Sensory | Response to pinprick on face, arms, trunk, and legs | 0–2 |
| 9. Best language | Aphasia testing: describe a picture, name objects, read sentences | 0–3 |
| 10. Dysarthria | Articulation clarity: read standard words aloud | 0–2 |
| 11. Extinction and inattention | Neglect: simultaneous bilateral stimulation (visual and tactile) | 0–2 |
Total score range: 0–42.
Interpreting the score
| NIHSS score | Stroke severity | Clinical implication |
|---|---|---|
| 0 | No deficits | Does not rule out stroke — consider posterior circulation event |
| 1–4 | Minor stroke | ~75% functional independence at 3 months |
| 5–15 | Moderate stroke | Likely candidate for thrombolysis or thrombectomy |
| 16–20 | Moderate-to-severe | Higher complication risk; ICU-level monitoring often needed |
| 21–42 | Severe stroke | High mortality; hemorrhagic transformation risk with tPA rises to ~17% vs ~3% for scores <10 |
Nursing tips for NIHSS administration:
- Score what the patient does, not what you think they can do. If the patient does not attempt a task, score the deficit.
- Repeat the NIHSS at consistent intervals — typically every 1–2 hours in the acute phase. A change of 2 or more points warrants immediate physician notification.
- Document the exact time of each assessment. Trending NIHSS scores is as important as trending vital signs.
- The NIHSS is certified training — most facilities require nursing staff to complete the online NIHSS certification before independently administering the scale.
Time-critical interventions: the treatment windows
Every treatment decision in ischemic stroke is anchored to the last-known-well (LKW) time — the last moment when someone confirmed the patient was at their neurological baseline. For wake-up strokes, LKW is when the patient went to sleep. This is not when symptoms were found — it is when the patient was last confirmed normal.
Thrombolytic therapy (tPA)
Intravenous thrombolytic therapy dissolves the occlusive clot and restores blood flow to the penumbra.
Alteplase remains the established standard: 0.9 mg/kg IV (max 90 mg), with 10% given as a bolus over 1 minute and the remaining 90% infused over 60 minutes.
Tenecteplase is increasingly used as a single IV bolus at 0.25 mg/kg. Current guidelines give it a Class 1 recommendation alongside alteplase for patients presenting within 4.5 hours, based on equivalent efficacy and simpler administration.
Treatment windows:
- Within 3 hours: Strongest evidence of benefit; standard eligibility criteria apply.
- 3–4.5 hours: Benefit persists but is smaller. Additional exclusion criteria apply: age >80, NIHSS >25, history of both diabetes and prior stroke, oral anticoagulant use regardless of INR.
- 4.5–9 hours (selected patients): May be reasonable when advanced imaging (CT perfusion or MRI diffusion-perfusion mismatch) confirms salvageable penumbra.
Absolute contraindications to tPA:
- Active internal bleeding (excluding menses)
- Recent intracranial surgery, serious head trauma, or prior stroke within 3 months
- History of intracranial hemorrhage
- Intracranial neoplasm, AVM, or aneurysm
- Platelets <100,000/mm³
- INR >1.7 or PT >15 seconds
- Heparin use within 48 hours with elevated aPTT
- Systolic BP that cannot be lowered below 185 mmHg or diastolic below 110 mmHg
- Blood glucose <50 or >400 mg/dL (unresponsive to treatment)
- CT evidence of hemorrhage or major acute infarct (>1/3 of a cerebral hemisphere)
Hospital target: door-to-needle time <60 minutes.
Mechanical thrombectomy
For large-vessel occlusion (LVO) ischemic strokes, mechanical thrombectomy using a stent retriever or aspiration catheter is standard of care.
- Treatment window: Up to 24 hours for selected patients with favorable imaging (mismatch between infarct core and salvageable tissue on CT perfusion or MRI).
- Eligible vessels: Internal carotid artery (ICA), M1 segment of the middle cerebral artery (MCA), and in some cases the basilar artery.
- Typical NIHSS: ≥6, indicating moderate-to-severe deficit.
- Thrombectomy can be performed in conjunction with IV tPA (bridging therapy) or as standalone treatment when tPA is contraindicated.
Acute nursing care: first 24 hours
The table below organizes nursing priorities by time phase during the acute stroke admission.
| Time phase | Priority actions | Rationale |
|---|---|---|
| 0–10 min (arrival) | Assess ABCs; establish LKW time; activate stroke alert; fingerstick glucose; two large-bore IVs; draw labs (CBC, BMP, coags, troponin); 12-lead ECG; continuous cardiac monitoring | LKW time is the single most important data point. Hypoglycemia must be excluded before any treatment. Cardiac monitoring detects AF as embolic source. |
| 10–20 min | Non-contrast CT head (do not delay for any reason); rapid neurological assessment; NIHSS; GCS; pupils | CT answers one question: hemorrhage or not? Hemorrhage = absolute tPA contraindication. Every treatment decision depends on this result. |
| 20–60 min (pre-treatment) | Review CT with stroke team; determine tPA eligibility; verify BP <185/110 (treat if elevated with IV labetalol or nicardipine); obtain informed consent; dysphagia screen (NPO until passed) | BP must be in range before tPA can be given. Dysphagia screen prevents aspiration from any oral intake including medications. |
| 60 min (tPA administration) | Administer alteplase or tenecteplase per weight-based protocol; double-check dose with second nurse; monitor VS and NIHSS every 15 min during infusion | Door-to-needle target <60 min. Dose errors with tPA are high-stakes — second-nurse verification is mandatory. |
| 1–6 hours post-tPA | BP maintenance <180/105 mmHg; neurological checks (NIHSS + VS) every 30 min; monitor for hemorrhagic transformation signs (severe headache, NIHSS worsening, new vomiting, acute hypertension); no arterial punctures, no NG tubes, no Foley insertion | Hemorrhagic transformation is the major tPA complication. Invasive procedures increase bleeding risk. |
| 6–24 hours | Neurological checks every 1–2 hours; maintain BP <180/105; continue cardiac monitoring; reassess dysphagia screen; glucose management (target 140–180 mg/dL); temperature management (treat fever >38°C aggressively); VTE prophylaxis (SCDs); CT at 24 h before starting antiplatelet/anticoag | Hyperglycemia worsens infarct size. Fever increases metabolic demand in compromised tissue. 24-hour CT confirms no hemorrhagic transformation before restarting anticoagulation or antiplatelets. |
| All phases | HOB positioning per facility protocol (30° for hemorrhagic; flat or 30° for ischemic based on aspiration risk); skin integrity (turn every 2 h); aspiration precautions; seizure precautions; Foley avoidance unless strict I&O required | Fever, aspiration pneumonia, CAUTI, and pressure injuries are the most common preventable complications of stroke hospitalizations. |
Post-thrombolysis nursing management
Post-tPA care is a defined nursing protocol with specific BP targets, monitoring frequencies, and bleeding precautions. This is high-yield NCLEX content.
Blood pressure management
| Phase | BP target | Action if exceeded |
|---|---|---|
| Before tPA | <185/110 mmHg | IV labetalol 10–20 mg over 1–2 min; may repeat. IV nicardipine infusion 5–15 mg/h if refractory. |
| During and after tPA (first 24 h) | <180/105 mmHg | IV labetalol 10 mg over 1–2 min, repeat q10–20 min up to 300 mg; or IV nicardipine infusion. If BP remains >230/140, consider sodium nitroprusside. |
| Ischemic stroke without tPA | Allow up to 220/120 mmHg (permissive hypertension) | Treat only if BP >220/120 or if end-organ damage evident (hypertensive encephalopathy, ACS, aortic dissection). |
Why permissive hypertension matters in ischemic stroke without tPA: The elevated pressure is the brain’s compensatory response to perfuse the penumbra through collateral vessels. Lowering it aggressively removes the driving force for collateral flow and can extend the infarct. This is counterintuitive — and frequently tested on NCLEX.
Neurological monitoring schedule
- During tPA infusion: NIHSS and full vital signs every 15 minutes
- Hours 1–6 post-tPA: Every 30 minutes
- Hours 6–24 post-tPA: Every 1 hour
Any NIHSS change of ≥2 points: notify provider immediately.
Hemorrhagic transformation: recognizing and responding
Hemorrhagic transformation occurs when reperfusion occurs through damaged vessels. Signs:
- Sudden, severe headache (not present at admission)
- Acute worsening of NIHSS score (especially LOC decline)
- New vomiting
- Acute hypertension after a period of stability
- Sudden decrease in SpO₂ or altered breathing pattern
Response protocol:
- Stop the tPA infusion immediately
- Call the provider — stat CT head required
- Keep the patient still; reduce stimulation
- Have cryoprecipitate (containing fibrinogen) and fresh frozen plasma available per facility protocol
- Do not restart infusion — even if CT later shows no large bleed
Bleeding precautions for 24 hours post-tPA
- No arterial punctures (femoral, radial, brachial)
- No central venous line insertion
- No nasogastric tube placement
- No Foley catheter insertion (place before tPA if anticipated, or use external collection device)
- No antiplatelet agents, anticoagulants, or NSAIDs for at least 24 hours (until 24-hour CT is reviewed)
- Soft toothbrush; no invasive oral care
- Apply direct pressure for at least 10 minutes to any venipuncture site
- Monitor all existing IV sites for oozing
Hemorrhagic stroke management
Management of hemorrhagic stroke differs fundamentally from ischemic stroke. The priorities are stopping the bleed, controlling pressure, and preventing secondary injury from hematoma expansion and elevated ICP.
Blood pressure control in ICH
Rapid reduction to a systolic target of 140 mmHg (range 130–150 mmHg) within the first few hours is recommended. IV nicardipine (5–15 mg/h infusion) and clevidipine allow precise, titratable control. The goal is to limit ongoing hematoma expansion, which occurs in approximately 30% of ICH patients within the first 3 hours.
Anticoagulation reversal agents
Time to reversal correlates directly with hematoma expansion and outcome. The correct reversal agent depends on which anticoagulant the patient was taking.
| Anticoagulant | Reversal agent(s) | Notes |
|---|---|---|
| Warfarin (vitamin K antagonist) | IV Vitamin K (phytonadione) + Four-factor prothrombin complex concentrate (4F-PCC) | 4F-PCC reverses INR faster than FFP (minutes vs. hours). Vitamin K alone takes 12–24 h. Use both. FFP is an alternative to PCC when PCC is unavailable. |
| Dabigatran (direct thrombin inhibitor) | Idarucizumab (Praxbind) 5 g IV | Humanized antibody fragment that binds dabigatran with high affinity. FDA-approved specific reversal. Dialysis also removes dabigatran. |
| Factor Xa inhibitors (rivaroxaban, apixaban, edoxaban) | Andexanet alfa (Andexxa) | Recombinant modified factor Xa that acts as a decoy to bind anti-Xa agents. Dose depends on specific agent and time of last dose. High cost limits availability — check formulary. |
| Unfractionated heparin | Protamine sulfate | 1 mg protamine per 100 units heparin given in last 2–3 h. Risk of anaphylaxis — have resuscitation equipment ready. |
| Low-molecular-weight heparin (enoxaparin) | Protamine sulfate (partial reversal) | Protamine only partially reverses LMWH; ~60–75% reversal. No fully effective reversal agent currently available for LMWH in emergency settings. |
Surgical considerations in hemorrhagic stroke
- External ventricular drain (EVD): Placed for obstructive hydrocephalus caused by intraventricular extension of blood. Also used for ICP monitoring. See the ICP nursing reference for EVD management principles.
- Craniotomy for cerebellar ICH: Large cerebellar hemorrhages (>3 cm) causing brainstem compression or hydrocephalus are surgical emergencies. Cerebellar herniation can cause respiratory arrest with little warning.
- Minimally invasive surgical evacuation: An evolving option for selected supratentorial ICH.
- SAH aneurysm securing: The ruptured aneurysm must be secured (surgical clipping or endovascular coiling) as early as possible to prevent rebleeding — which carries mortality exceeding 70%.
SAH-specific nursing monitoring
Subarachnoid hemorrhage has a unique complication timeline. After initial stabilization, the primary threat shifts to vasospasm — arterial narrowing from blood breakdown products in the subarachnoid space.
- Vasospasm peaks at days 4–14 after the initial bleed
- Nimodipine 60 mg every 4 hours orally for 21 days is standard prophylaxis
- Transcranial Doppler (TCD) ultrasound monitors cerebral blood flow velocities — elevated velocities signal developing vasospasm
- A patient who appeared stable on day 2 may deteriorate on day 8 — serial neurological assessments through the vasospasm window are essential
Also monitor closely for cerebral salt wasting (CSW): hyponatremia with volume depletion and high urine sodium. CSW is common in SAH and is frequently confused with SIADH (which causes hyponatremia with euvolemia). The distinction matters because treatment differs: CSW requires sodium and volume replacement; SIADH requires fluid restriction.
Dysphagia screening: why it matters and how to do it
Dysphagia screening must be completed before the patient takes anything by mouth — including medications, water, and ice chips. Up to 50% of acute stroke patients have some degree of swallowing dysfunction, and aspiration pneumonia is one of the most common, preventable, and potentially fatal complications of stroke hospitalization.
When to screen
- Immediately upon arrival for any patient with suspected stroke
- Before any oral medications, oral nutrition, or fluids
- Repeat after any change in neurological status (NIHSS change ≥2, new LOC change, new facial palsy)
- Before removing NPO status if the patient was sedated or had a procedure
Nursing dysphagia screen
Most facilities use a validated bedside screening protocol (Yale Swallow Protocol, water swallow test, or similar). A basic bedside approach involves:
- Level of consciousness: Patient must be alert enough to follow commands
- Oral motor assessment: Check for facial symmetry, lip closure, tongue movement, and voice quality (“wet” or gurgly voice suggests pooling in pharynx)
- 3-oz water swallow test (if applicable per facility protocol): Give 3 oz of water in continuous sips; any coughing, choking, wet voice, or change in SpO₂ = failed screen
- If the patient fails any step, maintain NPO and place a speech-language pathology (SLP) referral for formal swallowing evaluation
What to document
- Date and time of screen
- Patient’s level of alertness
- Presence or absence of cough reflex
- Presence of wet/gurgly voice after swallow
- Pass or fail outcome
- NPO status maintained or oral diet ordered (with texture modification if applicable)
- SLP referral placed (if failed)
While NPO
- Essential medications: administer IV or discuss with pharmacy about crushing and suspending medications in thickened liquid per SLP guidance
- Oral care every 2 hours to reduce bacterial colonization — micro-aspiration of oral secretions is a major driver of aspiration pneumonia even when the patient is NPO
- Document last oral intake
Secondary prevention and discharge planning
Once the acute phase is managed, the focus shifts to preventing recurrent stroke. Stroke recurrence risk is highest in the first 90 days — up to 15% after a TIA.
Antiplatelet therapy
For non-cardioembolic ischemic stroke:
- Minor stroke or TIA: Dual antiplatelet therapy — aspirin plus clopidogrel — started within 24 hours of symptom onset (or at least 24 hours after tPA if given). Transition to single antiplatelet after 21–90 days.
- Moderate-to-severe stroke: Single antiplatelet therapy (aspirin 81–325 mg/day) once 24-hour CT confirms no hemorrhagic transformation.
Anticoagulation for atrial fibrillation
AF-related cardioembolic stroke requires long-term anticoagulation:
- First choice: Direct oral anticoagulants (DOACs) — apixaban, rivaroxaban, dabigatran, or edoxaban
- When DOACs are contraindicated: Warfarin (INR target 2.0–3.0)
- Timing after acute stroke: Typically 4–14 days after the event, depending on infarct size (small infarct = earlier; large infarct = later, to reduce hemorrhagic transformation risk)
Educate patients on adherence, bleeding warning signs, drug interactions, and lab monitoring (INR for warfarin).
Statin therapy
High-intensity statin therapy (atorvastatin 40–80 mg or rosuvastatin 20–40 mg) is recommended for all patients with atherosclerotic ischemic stroke regardless of baseline LDL. Statins stabilize atherosclerotic plaques, reduce inflammation, and improve endothelial function beyond lipid lowering.
Blood pressure control
Long-term BP target is generally <130/80 mmHg once the acute phase resolves (typically after 48–72 hours for ischemic stroke). Thiazide diuretics, ACE inhibitors, and ARBs have the strongest evidence for stroke recurrence prevention.
Lifestyle modification
| Risk factor | Target |
|---|---|
| Smoking | Cessation — risk normalizes within 5 years |
| Physical activity | ≥150 minutes/week moderate aerobic exercise |
| Diet | Mediterranean or DASH pattern |
| Alcohol | Moderation; heavy drinking increases hemorrhagic stroke risk |
| Weight | BMI <25 where achievable |
| Diabetes | HbA1c <7% for most patients |
Rehabilitation priorities: starting early
Stroke rehabilitation begins in the acute phase — not after discharge. Early mobilization within 24–48 hours of admission (when medically stable) reduces complications including DVT, pneumonia, deconditioning, and depression.
Mobilization timeline
| Time | Mobility goal |
|---|---|
| 0–24 h | HOB elevation; passive range of motion to affected limbs; sitting at edge of bed if hemodynamically stable |
| 24–48 h | Dangle; stand with assist; transfer to chair if tolerated; initiate PT/OT evaluation |
| 48–72 h | Ambulation with assistive device; ADL participation as tolerated |
| Ongoing | Progressive activity advancement per PT/OT goals; prevent learned non-use of affected limb |
Important exception: Patients receiving tPA or who are hemodynamically unstable should not be mobilized until the physician clears them. Post-tPA, no active mobilization for at least 24 hours in most protocols.
Rehabilitation team roles
Physical therapy (PT): Mobility, gait training, balance and fall prevention, strengthening of affected extremities, assistive device selection.
Occupational therapy (OT): Activities of daily living (ADLs) — dressing, bathing, grooming; adaptive equipment; upper extremity function; cognitive rehabilitation for spatial neglect.
Speech-language pathology (SLP): Formal swallowing evaluation and dysphagia management; aphasia treatment (expressive and receptive); cognitive-communication deficits; augmentative communication devices.
Nursing role in rehabilitation:
- Reinforce therapy gains between PT/OT/SLP sessions — use mealtimes, ADLs, and repositioning as therapeutic opportunities
- Consistently approach the patient from the affected side to encourage awareness and reduce neglect
- Encourage independence — allow the patient time to attempt tasks rather than doing everything for them
- Document functional changes in response to therapy
Complications that impair rehabilitation
- Shoulder pain and subluxation: Common in flaccid hemiplegia. Use arm slings, proper positioning, and support during transfers. Never pull on the affected arm.
- Spasticity: Develops weeks after stroke; treated with stretching, positioning, and medications (baclofen, botulinum toxin).
- Depression: Occurs in 30–40% of stroke survivors and directly impairs rehabilitation participation. Screen with PHQ-9 or similar tool. Early treatment (SSRIs) improves both mood and functional outcomes.
- Cognitive impairment: Executive function, attention, and memory deficits affect up to 30% of stroke survivors beyond physical deficits. Involves OT cognitive rehabilitation and environmental modifications.
Nursing interventions by system: reference table
| System | Key interventions | Rationale |
|---|---|---|
| Neurological | NIHSS and GCS per protocol; pupil checks; HOB 30° (hemorrhagic) or per protocol (ischemic); seizure precautions; ICP monitoring if indicated | NIHSS change ≥2 = notify provider. Early detection of herniation or transformation prevents catastrophic outcomes. |
| Cardiovascular | Continuous cardiac monitoring ≥24 h; BP per stroke-type protocol; 12-lead ECG; watch for AF, bradycardia, QT prolongation; VTE prophylaxis (SCDs on admission) | AF detection changes secondary prevention strategy. Cardiac monitoring reveals neurogenic stunned myocardium in SAH. |
| Respiratory | SpO₂ monitoring; O₂ supplementation if SpO₂ <94%; aspiration precautions; cough and deep breathing; suction at bedside; HOB ≥30° for any oral intake | Aspiration pneumonia is the most common preventable complication. Review [ABG interpretation](/nursing-tips/abg-interpretation/) for respiratory monitoring in neurological patients. |
| Metabolic | Glucose monitoring q4–6h; target 140–180 mg/dL; treat fever aggressively (acetaminophen + cooling); temperature q4h | Hyperglycemia and fever both increase metabolic demand in ischemic penumbra and worsen infarct size. |
| GI / nutrition | NPO until dysphagia screen passed; SLP referral if failed; oral care q2h while NPO; NG or PEG tube for prolonged dysphagia; aspiration precautions with all oral intake | 50% of acute stroke patients have dysphagia. Aspiration pneumonia mortality in stroke is significant. |
| Genitourinary | Avoid Foley unless strict I&O required; reassess catheter need daily; intermittent catheterization preferred; monitor for CAUTI signs (fever, cloudy urine, urgency) | CAUTI is a leading cause of fever in stroke patients, and fever worsens neurological outcomes. |
| Integumentary | Turn every 2 hours; pressure-redistribution surfaces; skin assessment with each repositioning; approach patient from affected side | Hemiparesis eliminates the patient's ability to self-reposition; diminished sensation on affected side means pressure injuries develop without pain warning. |
| Psychosocial | Explain all procedures and findings clearly; involve family in orientation and reassurance; screen for depression (PHQ-9); provide aphasia-friendly communication supports; facilitate early family education on stroke signs | Post-stroke depression occurs in 30–40% of patients. Family preparation for discharge and recurrence prevention is a nursing responsibility. |
NANDA-I nursing care plans for stroke
A stroke nursing care plan translates assessment findings into a structured framework: a NANDA-I nursing diagnosis statement, measurable expected outcomes, and evidence-based interventions with rationale. The five plans below address the highest-priority problems nurses manage across the acute and subacute stroke continuum.
Care plan 1: risk for ineffective cerebral tissue perfusion
NANDA-I diagnosis: Risk for ineffective cerebral tissue perfusion related to cerebral ischemia, arterial occlusion, thrombus formation, hemorrhage, or cerebral edema.
(This is a risk diagnosis — no “as evidenced by” defining characteristics. Risk factors drive the diagnosis.)
Risk factors: Arterial occlusion or stenosis; cardioembolic source (atrial fibrillation, valvular disease); hypertension; diabetes; hypercoagulable state; cerebral edema post-infarct; hemorrhagic transformation; elevated ICP.
Expected outcomes:
- Patient maintains NIHSS score at baseline or demonstrates documented improvement within 24 hours of admission.
- Patient maintains mean arterial pressure (MAP) within the prescribed therapeutic range throughout hospitalization.
- Patient remains free from signs of herniation (Cushing’s triad, pupillary changes) or secondary neurological deterioration during acute phase.
- Patient’s blood glucose remains within 140–180 mg/dL during the first 72 hours.
| Nursing intervention | Rationale |
|---|---|
| Perform and document serial NIHSS assessments per protocol (every 1–2 hours in the acute phase); report any change of ≥2 points to the provider immediately. | The NIHSS is the validated instrument for trending neurological status. A ≥2-point change indicates clinically significant deterioration — early detection allows intervention before irreversible penumbral loss occurs. |
| Establish and document the last-known-well (LKW) time on admission; display it prominently in the bedside documentation for the entire stroke team. | All time-sensitive reperfusion decisions — tPA eligibility, thrombectomy window — are anchored to LKW time, not time of discovery. Accurate documentation prevents missed treatment windows. |
| For ischemic stroke without tPA: allow blood pressure up to 220/120 mmHg (permissive hypertension); treat only if this threshold is exceeded or end-organ damage is present. | Elevated blood pressure in acute ischemic stroke supports collateral perfusion of the ischemic penumbra. Aggressive early lowering reduces cerebral perfusion pressure and can extend infarct size — a counterintuitive principle that is high-yield on NCLEX. |
| For tPA-eligible patients: reduce and maintain BP <185/110 mmHg before administration; maintain <180/105 mmHg for 24 hours post-infusion using IV labetalol or nicardipine per protocol. | tPA is absolutely contraindicated if BP cannot be brought below 185/110 mmHg. Post-infusion, exceeding 180/105 mmHg significantly increases hemorrhagic transformation risk by reperfusing through damaged vessel walls. |
| Monitor and maintain blood glucose at 140–180 mg/dL using a validated sliding scale or insulin drip protocol; treat hypoglycemia (<70 mg/dL) immediately with dextrose. | Both hyperglycemia and hypoglycemia worsen neurological outcomes in stroke. Hyperglycemia increases ischemic injury through acidosis and free-radical production; hypoglycemia causes direct neuronal energy failure and can mimic or worsen stroke symptoms. |
| Monitor and treat fever (temperature >38°C / 100.4°F) aggressively with scheduled acetaminophen and cooling measures; obtain blood and urine cultures to identify infectious sources. | Fever raises cerebral metabolic demand in the ischemic penumbra, accelerating neuronal death. Each degree Celsius of fever is associated with worsened neurological outcomes and larger final infarct size. |
| Maintain head-of-bed (HOB) positioning per physician orders: typically 0–30° flat during the first 24 hours for ischemic stroke (to maximize cerebral perfusion); elevate to 30° or greater if aspiration risk exists or hemorrhagic stroke is confirmed. | Flat positioning increases cerebral perfusion pressure by reducing the vertical hydrostatic gradient between the heart and brain, supporting penumbral perfusion in ischemic stroke. Elevation is used for hemorrhagic stroke where ICP reduction takes priority over penumbral perfusion. |
| Assess pupils every 1–2 hours: size, equality, and reactivity. Report unequal, dilated, or non-reactive pupils immediately. | Unilateral pupil dilation (blown pupil) is a sign of uncal herniation from transtentorial pressure — a neurological emergency requiring immediate intervention. Pupil changes often precede other clinical signs of deterioration. |
| Avoid clustering care activities; minimize environmental stimulation and noise during the acute phase; ensure adequate oxygenation (maintain SpO₂ ≥94%, supplement only if below this threshold). | Unnecessary stimulation raises cerebral metabolic demand and blood pressure. Routine oxygen supplementation in normoxic patients is not recommended and may cause harm; oxygen is administered only when SpO₂ falls below 94%. |
| Prepare and anticipate the use of osmotic therapy (mannitol, hypertonic saline) for signs of elevated ICP or cerebral edema per order; monitor serum sodium and osmolality if osmotic therapy is initiated. | Malignant cerebral edema peaks at 3–5 days post-infarct in large MCA strokes, causing fatal herniation if untreated. Early recognition and osmotic therapy can temporize while decompressive craniectomy is considered. See the ICP nursing reference for full management principles. |
Care plan 2: impaired physical mobility
NANDA-I diagnosis: Impaired physical mobility related to neuromuscular impairment secondary to cerebral ischemia or hemorrhage, as evidenced by hemiplegia or hemiparesis, decreased muscle strength on the affected side, impaired coordination, and inability to purposefully move within the physical environment.
Expected outcomes:
- Patient participates in passive range-of-motion exercises to all affected joints at least twice daily within 24 hours of admission.
- Patient demonstrates safe transfer technique with appropriate assist level by discharge.
- Patient maintains skin integrity without new pressure injuries throughout hospitalization.
- Patient achieves highest functional level possible within physical limitations, as defined by PT/OT goals, prior to discharge.
| Nursing intervention | Rationale |
|---|---|
| Assess functional status on admission using a standardized scale (Functional Independence Measure or Barthel Index); document baseline motor strength and coordination in all four extremities. | Baseline functional documentation establishes a reference point for measuring recovery, guides therapy goals, and informs safe mobility planning. It also provides legal documentation of pre-hospitalization function. |
| Initiate passive range-of-motion (PROM) exercises to all joints of the affected extremities at least twice daily; progress to active-assisted ROM as tolerated; collaborate with PT within 24–48 hours of admission. | PROM prevents contracture formation, maintains joint integrity, stimulates proprioception, and supports neuromuscular remodeling. Early PT involvement optimizes rehabilitation trajectory. Exception: delay active mobilization until physician clearance post-tPA. |
| Position the affected extremities in functional alignment using positioning aids: pillow under affected arm with shoulder at 90° abduction when supine; hand in slight extension with fingers separated; rolled towel under affected hip to prevent external rotation. | Post-stroke spasticity develops in flexor pattern in the upper extremity and extensor pattern in the lower extremity. Functional positioning counteracts these patterns, prevents contracture, and supports joint integrity before spasticity develops. |
| Never lift or pull on the affected arm during repositioning or transfers. Support the affected limb fully during all movements. | The hemiplegic shoulder is at high risk for subluxation and rotator cuff injury because supporting muscle tone is absent. Pulling on a flaccid arm can cause shoulder subluxation and chronic pain syndrome — a preventable complication that impairs rehabilitation. |
| Reposition the patient every 2 hours using a documented turning schedule; use pressure-redistribution mattress surfaces; perform skin assessment with each turn, paying close attention to the affected (anesthetic) side. | Hemiplegia eliminates the normal reflexive repositioning that prevents pressure injury. Diminished or absent sensation on the affected side removes the pain signal that would otherwise prompt movement. Without a structured turning schedule, pressure injuries are nearly inevitable. |
| Consistently approach the patient from the affected side during care activities; place call light, water, and personal items on the affected side (once safety permits). | Approaching and placing objects on the affected side encourages the patient to attend to and use that side, directly counteracting unilateral neglect and promoting cortical reorganization. This simple nursing behavior has measurable impact on neglect recovery. |
| Implement fall prevention measures: call light within reach, non-skid footwear, bed alarm per protocol, bed in lowest position, bedside rails up, walkway clear of equipment; educate patient and family on fall risk. | Hemiparesis, altered proprioception, visual field deficits, and cognitive changes produce a high fall risk in stroke patients. Falls cause additional injury in a population already physiologically vulnerable. Individualized fall prevention is a Joint Commission National Patient Safety Goal. |
| Encourage the patient to use the unaffected extremity to assist in repositioning and ADLs; provide positive reinforcement for participation; allow adequate time for task completion without rushing. | Learned non-use of the affected limb is a well-documented phenomenon where patients abandon attempting to use the affected side after repeated failures. Encouraging independent effort — even slow or partial — reinforces motor cortex recruitment and supports neuroplasticity. |
| Initiate VTE prophylaxis per order on admission: sequential compression devices (SCDs) to both lower extremities; pharmacological prophylaxis (low-molecular-weight heparin or unfractionated heparin) once cleared by physician — typically after 24-hour CT confirms no hemorrhagic transformation. | Immobility and paralysis dramatically increase deep vein thrombosis risk in stroke patients. SCDs are safe immediately; pharmacological anticoagulation is deferred until hemorrhagic transformation is excluded on 24-hour CT to avoid worsening any undetected bleeding. |
Care plan 3: impaired verbal communication
NANDA-I diagnosis: Impaired verbal communication related to aphasia or dysarthria secondary to cerebral injury in language-dominant hemisphere or corticobulbar tract involvement, as evidenced by inability to speak, inappropriate verbalization, difficulty finding words, impaired articulation, and inability to comprehend spoken or written language.
Expected outcomes:
- Patient establishes a reliable yes/no or augmentative communication method within 48 hours of admission.
- Patient and family demonstrate use of at least two communication strategies to convey needs prior to discharge.
- Patient receives formal speech-language pathology (SLP) evaluation within 24 hours of admission.
- Patient expresses reduced frustration with communication attempts, as verbalized or demonstrated, prior to discharge.
| Nursing intervention | Rationale |
|---|---|
| Assess the type of aphasia on admission: expressive (Broca's — difficulty producing speech but comprehension intact), receptive (Wernicke's — fluent but meaningless speech, poor comprehension), or global (both). Document baseline language function and refer to SLP within 24 hours. | Distinguishing aphasia type guides communication strategy. Expressive aphasia patients understand what is said — use yes/no questions, gesture, and written communication. Receptive aphasia patients need simplified language, visual cues, and demonstrations. Misidentifying the type leads to ineffective communication attempts that increase distress. |
| Speak slowly and clearly using short, simple sentences; allow adequate response time (30–60 seconds or longer) before prompting or moving on; maintain a calm, unhurried demeanor. | Language processing is slowed by cerebral injury. Patients with aphasia need significantly more time to decode incoming speech and formulate responses. Rushing increases anxiety, which further impairs language performance. Patience is a direct therapeutic intervention. |
| Use augmentative communication tools appropriate to the patient's deficits: communication boards with pictures and words, alphabet boards for letter-by-letter spelling, writing pads, tablet-based AAC apps, or simple gesture systems. | Aphasia does not equal intellectual impairment. Patients retain the ability to communicate when alternative channels are available. Communication boards reduce frustration, help meet safety needs, and maintain the patient's sense of agency during recovery. |
| Address the patient as a capable adult; avoid speaking about the patient in the third person in their presence; explain all procedures before performing them; correct family members who may talk "over" the patient. | Aphasia is a language disorder, not a cognitive one. Treating patients as if they are intellectually impaired causes psychological harm, reduces cooperation, and reinforces learned helplessness. Preserved cognition with impaired expression is a frequently misunderstood aspect of stroke care. |
| Minimize background noise and distractions during communication attempts; turn off the television; ensure the patient has glasses and hearing aids in place if used. | Sensory competition worsens the processing burden in aphasic patients. Optimal sensory conditions — quiet environment, corrected vision, corrected hearing — maximize the patient's communicative capacity. |
| Recognize and validate the patient's frustration; provide honest, empathetic acknowledgment ("I know this is frustrating. We are working on finding the best way to communicate with you"). | Loss of speech is psychologically devastating. Up to 70% of patients with post-stroke aphasia develop depression, which in turn impairs rehabilitation participation. Emotional validation is a therapeutic intervention that directly supports recovery. |
| Educate family members on communication strategies before each visit: speak one at a time, use simple language, allow response time, do not correct or complete sentences, celebrate effort not perfection. | Family members are the patient's primary communication partners. Without guidance, they often inadvertently use patterns that frustrate aphasic patients — finishing sentences, asking multiple questions, speaking too fast. Family education extends therapeutic communication beyond nursing interactions. |
| Document communication assessment findings, strategies that work, and patient response at each nursing interaction; ensure consistency across the care team by including communication preferences in the care plan and handoff report. | Communication strategies are only effective when used consistently by all providers. Fragmented approaches — each nurse trying different techniques — slow progress and increase frustration. A documented, standardized approach promotes continuity and measurable improvement. |
Care plan 4: risk for aspiration
NANDA-I diagnosis: Risk for aspiration related to dysphagia secondary to neuromuscular impairment, decreased level of consciousness, and impaired gag reflex following stroke.
(Risk diagnosis — no defining characteristics required.)
Risk factors: Dysphagia from pharyngeal or laryngeal muscle weakness; reduced or absent gag reflex; decreased level of consciousness; impaired cough reflex; facial or tongue weakness; tracheal or esophageal obstruction; enteral tube feeding; impaired swallowing secondary to corticobulbar tract injury.
Expected outcomes:
- Patient undergoes formal dysphagia screening before any oral intake or oral medications during this admission.
- Patient remains free from aspiration pneumonia throughout hospitalization, as evidenced by absence of fever, respiratory changes, and new pulmonary infiltrates.
- Patient demonstrates safe swallowing with appropriate dietary texture modification if indicated, prior to discharge.
- Oral care is performed every 2 hours while patient remains NPO or at high aspiration risk.
| Nursing intervention | Rationale |
|---|---|
| Perform or ensure validated dysphagia screening (Yale Swallow Protocol, bedside water swallow test, or facility-approved tool) before any oral intake — including water, ice chips, and oral medications — on admission and after any significant change in neurological status (NIHSS change ≥2, decreased LOC, new facial palsy). | Up to 50% of acute stroke patients have some degree of swallowing dysfunction on admission. Silent aspiration — aspiration without cough reflex — occurs in up to 40% of dysphagic stroke patients. The only way to identify these patients is systematic screening before any oral intake. Dysphagia screening reduces aspiration pneumonia rates by up to 80% in acute stroke units. |
| Maintain strict NPO status for any patient who fails dysphagia screening; place SLP referral immediately; document NPO status and reason in the medical record; communicate NPO status clearly at each handoff. | A failed dysphagia screen is a safety finding, not a preliminary test. NPO must be maintained until formal SLP evaluation is complete and dietary modifications are prescribed. Poor handoff communication around NPO status is a leading cause of aspiration events during care transitions. |
| Position all patients at 90° (fully upright) for any oral intake or oral medications; maintain upright positioning for at least 30 minutes after meals; never feed a patient who is supine or semi-recumbent. | Upright positioning uses gravity to direct food and liquid toward the esophagus rather than the trachea, reducing aspiration risk. Reclined feeding is a known causal factor in aspiration pneumonia in neurologically impaired patients. |
| Perform oral care every 2 hours while the patient remains NPO or at high aspiration risk: brush teeth or dentures, suction oropharyngeal secretions, apply oral moisturizer; use a suction toothbrush if available. | The oral cavity is colonized with gram-negative and anaerobic bacteria within hours of stroke admission. Silent micro-aspiration of these colonized secretions — even in NPO patients — is the primary mechanism of aspiration pneumonia. Rigorous oral care is as protective as dietary restriction. |
| Monitor for signs of aspiration during and after any oral intake: coughing during swallowing, wet or gurgly voice quality, changes in SpO₂ ≥2% during eating, nasal regurgitation, or patient report of food sticking. Stop feeding immediately and reassess if any sign appears. | Not all aspiration events are visible. SpO₂ monitoring during meals and voice quality assessment after swallowing detect silent and near-silent aspiration that clinical observation alone misses. Early detection prevents cumulative aspiration that leads to pneumonia. |
| Administer thickened liquids and texture-modified foods per SLP recommendation; educate patient and family on prescribed texture level (IDDSI levels 0–7) and rationale; document dietary level in the care plan and ensure dietary services orders match SLP recommendations. | Texture modification is the primary intervention for oropharyngeal dysphagia. IDDSI standardized levels ensure consistent terminology across the care team. Discordance between SLP recommendations and dietary service orders — a common error — causes aspiration events that appear to be clinical failures. |
| For patients requiring prolonged NPO status: advocate for early SLP evaluation, discuss enteral feeding options with the team (nasogastric tube initially; PEG tube consideration if dysphagia is expected to persist beyond 3–4 weeks), and ensure IV or nasogastric administration of essential medications. | Adequate nutrition is essential for stroke recovery and wound healing. Early enteral nutrition via NG tube reduces infection risk, supports metabolic needs, and avoids the immunosuppression of prolonged starvation. PEG placement is considered when long-term dysphagia is anticipated. |
| Assess and document gag reflex and cough strength at each shift; report new or worsening absence of gag reflex to the provider. | Absent gag reflex and impaired voluntary cough are independent predictors of aspiration. Trending these findings identifies patients whose aspiration risk is increasing, prompting escalation of precautions or escalation to the physician before an adverse event occurs. |
| Suction equipment should be available and functional at the bedside for any patient at high aspiration risk; verify suction function at the start of each shift. | Prompt suctioning of aspirated material reduces the volume and dwell time of aspirated secretions in the airway, limiting pneumonitis and pneumonia. Equipment failure during an aspiration event is a preventable systems failure. |
Care plan 5: impaired swallowing
NANDA-I diagnosis: Impaired swallowing related to neuromuscular impairment of the pharyngeal and laryngeal muscles secondary to stroke, as evidenced by observed difficulty swallowing, coughing or choking with oral intake, wet/gurgly voice quality, drooling, or inability to clear oral secretions.
Expected outcomes:
- Patient demonstrates improved swallowing function as evidenced by passing formal SLP swallowing evaluation or progressing to a less-restrictive dietary texture within 7 days.
- Patient maintains adequate caloric intake (≥75% of calculated nutritional needs) via safest appropriate feeding route by day 5 of admission.
- Patient and family verbalize understanding of prescribed dietary modifications and aspiration precautions prior to discharge.
- Patient remains free from complications of dysphagia (aspiration pneumonia, dehydration, malnutrition) throughout hospitalization.
| Nursing intervention | Rationale |
|---|---|
| Assess swallowing function at each meal: observe for pocketing of food in the cheeks, drooling, prolonged chewing, multiple swallows per bolus, coughing, voice change after swallowing, and patient reports of difficulty. | Swallowing function fluctuates in acute stroke, influenced by fatigue, neurological changes, and medication effects. Systematic observation at each meal detects deterioration early and guides communication with SLP about dietary progression or escalation of restrictions. |
| Implement chin-tuck maneuver during swallowing if recommended by SLP; ensure consistent use at all meals and medication administrations; educate patient and all caregivers on the technique. | The chin-tuck maneuver widens the vallecular space, narrows the laryngeal entrance, and slows bolus transit, reducing aspiration risk for patients with delayed pharyngeal swallow trigger. It is one of the most evidence-based compensatory strategies for pharyngeal dysphagia. |
| Provide meals in small portions with adequate rest periods between bites; allow adequate time without rushing; limit conversation and distractions during eating. | Fatigue significantly worsens swallowing function in stroke patients, particularly in the afternoon. Small portions maintain the patient's alertness and reduce the effort per swallow. Cognitive load from conversation or distraction impairs the voluntary control component of swallowing. |
| Perform and document food and fluid intake at each meal; report consistent intake below 75% of estimated needs to the dietitian and physician; weigh patient daily or every other day. | Malnutrition is a significant and often overlooked complication of post-stroke dysphagia. It impairs wound healing, immune function, and rehabilitation capacity. Systematic intake documentation is the only way to identify inadequate nutrition before clinical signs of malnutrition appear. |
| Prepare the environment for meals: ensure the patient is fully awake and alert before eating; schedule meals when the patient is at highest alertness; reduce room noise; ensure dentures, glasses, and hearing aids are in place; remove non-food items from the food tray. | Alertness is a prerequisite for safe voluntary swallowing. Eating while drowsy is a direct aspiration risk factor. Environmental optimization removes sensory barriers that impair the complex voluntary-reflex coordination required for safe deglutition. |
| Collaborate with the pharmacist to identify medications that can be safely crushed or administered in liquid form; verify with SLP before changing medication formulations for dysphagia patients. | Many stroke medications are time-sensitive (antiplatelets, antihypertensives, antiepileptics). Crushing certain formulations — especially extended-release or enteric-coated preparations — alters pharmacokinetics and can cause toxicity or treatment failure. Pharmacist and SLP collaboration ensures safe medication delivery without compromising efficacy. |
| Document swallowing assessment findings, dietary texture level, intake volume, and any aspiration events or signs in the medical record at each nursing interaction; communicate changes to SLP and the interdisciplinary team. | Swallowing management is an interdisciplinary process. Fragmented or inconsistent documentation creates information gaps that cause dietary texture inconsistencies across shifts, delays in dietary progression, and missed complications. Complete documentation drives coordinated, evidence-based care. |
| Provide discharge education to patient and family covering: prescribed dietary texture level at home, foods and liquids to avoid, positioning requirements for meals, warning signs of aspiration (coughing during or after meals, wet voice, recurrent chest infections), and when to seek SLP follow-up. | Dysphagia often persists beyond the acute hospital stay. Patients and caregivers who lack structured discharge education frequently resume unsafe textures at home — the primary cause of post-discharge aspiration pneumonia. Structured discharge education is a direct safety intervention. |
Frequently asked questions: stroke nursing
What is the priority nursing intervention for a patient with acute stroke?
The highest-priority nursing intervention is establishing and documenting the last-known-well (LKW) time — the last moment a witness confirmed the patient was at neurological baseline. This single data point determines eligibility for every time-sensitive reperfusion treatment, including IV tPA (window: up to 4.5 hours) and mechanical thrombectomy (window: up to 24 hours for selected patients). Without an accurate LKW time, the entire treatment decision tree collapses. Concurrent first priorities include activating the stroke alert, assessing the ABCs, checking a fingerstick blood glucose to exclude hypoglycemia as a stroke mimic, and establishing IV access. The priority nursing action before tPA administration is verifying blood pressure is <185/110 mmHg.
What is the most important nursing diagnosis for stroke?
The highest-priority NANDA-I nursing diagnosis for acute stroke is risk for ineffective cerebral tissue perfusion, related to cerebral ischemia, thrombus, or hemorrhage. This is a risk diagnosis — there are no defining characteristics required because the risk factors themselves (arterial occlusion, cerebral edema, hemorrhage) are sufficient to establish the diagnosis. It takes priority because it addresses the underlying pathophysiology driving all other problems. Impaired physical mobility, impaired verbal communication, risk for aspiration, and impaired swallowing are all secondary manifestations of the primary perfusion deficit.
What are the key nursing interventions for ischemic stroke?
Core nursing interventions for ischemic stroke include: (1) establishing LKW time and activating the stroke alert; (2) obtaining non-contrast CT head immediately to exclude hemorrhage; (3) achieving blood pressure <185/110 mmHg if tPA is planned; (4) administering IV alteplase or tenecteplase within 4.5 hours of onset if eligible; (5) serial NIHSS assessments every 1–2 hours; (6) monitoring for hemorrhagic transformation post-tPA (sudden headache, BP spike, vomiting, NIHSS worsening); (7) maintaining blood glucose 140–180 mg/dL; (8) treating fever aggressively; (9) dysphagia screening before any oral intake; and (10) VTE prophylaxis with sequential compression devices on admission.
What does FAST stand for in stroke assessment?
FAST is a prehospital and nursing mnemonic for recognizing stroke: Face drooping (ask the patient to smile — is one side drooping or numb?), Arm weakness (ask the patient to raise both arms — does one drift downward?), Speech difficulty (ask the patient to repeat a simple sentence — is it slurred or garbled?), and Time to call 911 (note the exact time symptoms began and activate emergency services immediately). The expanded mnemonic BE-FAST adds Balance loss (sudden dizziness, ataxia, difficulty walking) and Eye changes (sudden visual field loss or double vision) to capture posterior circulation strokes, which FAST alone misses in roughly 20% of cases.
When is tPA contraindicated in stroke?
tPA (alteplase or tenecteplase) is absolutely contraindicated in several situations: confirmed hemorrhagic stroke on CT; active internal bleeding (excluding menses); prior intracranial hemorrhage; intracranial neoplasm, AVM, or aneurysm; intracranial surgery or serious head trauma within 3 months; recent ischemic stroke within 3 months; platelet count <100,000/mm³; INR >1.7 or PT >15 seconds; heparin use within 48 hours with elevated aPTT; blood pressure that cannot be brought below 185/110 mmHg; blood glucose <50 mg/dL unresponsive to treatment; and CT findings showing major acute infarct (>1/3 of a cerebral hemisphere). For the 3–4.5-hour window, additional relative contraindications apply: age over 80, NIHSS over 25, prior stroke combined with diabetes, and use of oral anticoagulants regardless of INR.
How do you perform a neurological assessment on a stroke patient?
A systematic stroke neurological assessment uses the NIHSS as its primary tool — an 11-item scale covering level of consciousness, orientation, gaze, visual fields, facial palsy, arm and leg motor strength, limb ataxia, sensory function, language, dysarthria, and extinction/inattention. Assess and document NIHSS at admission, at regular intervals (every 1–2 hours in the acute phase), and before and after any intervention. Complement the NIHSS with: Glasgow Coma Scale (for LOC trending), pupil assessment (size, equality, reactivity — unequal pupils signal herniation), vital signs, blood glucose, and observation for signs of hemorrhagic transformation. Report any NIHSS change of ≥2 points to the provider immediately. The Glasgow Coma Scale guide covers LOC assessment principles in detail.
What is the difference between ischemic and hemorrhagic stroke nursing management?
The key nursing management differences turn on blood pressure targets, tPA eligibility, and the urgency of anticoagulation reversal. For ischemic stroke: allow permissive hypertension up to 220/120 mmHg (supports penumbral perfusion); lower to <185/110 mmHg if tPA is planned; administer IV tPA within 4.5 hours if eligible; no anticoagulant reversal needed unless the patient was anticoagulated before the stroke. For hemorrhagic stroke: tPA is absolutely contraindicated; the priority is aggressive BP reduction to systolic <140 mmHg (ICH) to limit hematoma expansion; anticoagulation reversal is emergent (warfarin → vitamin K + 4F-PCC; dabigatran → idarucizumab; factor Xa inhibitors → andexanet alfa); ICP monitoring and surgical consultation are often indicated. Dysphagia screening, fever management, glucose control, and VTE prophylaxis apply to both stroke types. For hemorrhagic stroke specifics, see the intracranial hemorrhage nursing reference.
What are the signs of hemorrhagic transformation after tPA?
Hemorrhagic transformation — reperfusion bleeding through damaged vessel walls — is the most feared complication of IV thrombolysis. Warning signs include: sudden, severe headache that was not present at admission (the most specific symptom); acute worsening in NIHSS score of ≥4 points, particularly new decline in level of consciousness; new vomiting; acute blood pressure surge after a period of stability; and new neurological deficits that were not present at baseline. The nursing response is immediate: stop the tPA infusion, call the provider stat, arrange emergency CT head, and have cryoprecipitate (fibrinogen replacement) and fresh frozen plasma available per facility protocol. Do not restart the infusion under any circumstances.
NCLEX-style questions
Test your knowledge with these 6 questions. Each reflects a high-frequency NCLEX stroke concept.
Question 1
A nurse is preparing to administer alteplase to a patient with acute ischemic stroke. The patient’s BP is 192/108 mmHg. What is the priority nursing action?
A) Administer the alteplase immediately and then treat the hypertension B) Hold the alteplase and administer IV labetalol or nicardipine as ordered C) Notify the provider that the patient cannot receive alteplase D) Recheck the BP in 30 minutes before making any decision
Answer: B
Rationale: Blood pressure must be <185/110 mmHg before alteplase can be administered. The correct approach is to hold the medication and promptly reduce BP with IV antihypertensives (labetalol 10–20 mg IV over 1–2 min, or nicardipine infusion) to bring it into the eligible range. Option A is incorrect — administering tPA with BP above threshold increases hemorrhagic transformation risk. Option C is premature — eligibility is not permanently lost if BP can be lowered. Option D is incorrect because a 30-minute delay risks irreversible penumbral damage (“time is brain”).
Question 2
A patient who received IV alteplase 45 minutes ago reports a sudden, severe headache and the nurse notes an acute increase in blood pressure and new vomiting. What is the priority action?
A) Increase the rate of the alteplase infusion to complete it faster B) Reassure the patient that headache is a common side effect of tPA C) Stop the tPA infusion immediately and notify the provider D) Administer IV acetaminophen for headache and continue monitoring
Answer: C
Rationale: Sudden severe headache, acute hypertension, and new vomiting during or after tPA infusion are warning signs of intracranial hemorrhage (hemorrhagic transformation). The infusion must be stopped immediately, the provider notified, and a stat CT head arranged. Continuing the infusion (A) would worsen the bleed. Reassurance (B) is inappropriate — these are not expected side effects; headache plus vomiting plus BP spike is an emergency presentation. Treating headache symptomatically (D) delays critical intervention.
Question 3
A patient with a history of atrial fibrillation who takes warfarin presents with acute intracerebral hemorrhage. The INR is 3.2. Which combination of reversal agents should the nurse anticipate administering?
A) Protamine sulfate and fresh frozen plasma B) Idarucizumab and vitamin K C) Andexanet alfa and 4F-PCC D) IV vitamin K and four-factor prothrombin complex concentrate (4F-PCC)
Answer: D
Rationale: Warfarin is reversed with IV vitamin K (phytonadione) plus 4F-PCC. Vitamin K alone takes 12–24 hours to reduce INR; 4F-PCC provides immediate replacement of clotting factors II, VII, IX, and X. Using both together achieves rapid reversal and sustained effect. Option A (protamine) is used for heparin, not warfarin. Option B (idarucizumab) reverses dabigatran specifically. Option C (andexanet alfa) reverses factor Xa inhibitors (rivaroxaban, apixaban). Recognizing which reversal agent matches which anticoagulant class is a key NCLEX pharmacology concept.
Question 4
A nurse is caring for a patient admitted 36 hours ago for subarachnoid hemorrhage who initially had a Glasgow Coma Scale score of 14 and was conversational. Today the patient is confused, has new left arm weakness, and a transcranial Doppler shows elevated blood flow velocities. What complication does the nurse recognize?
A) Rebleeding from the aneurysm B) Cerebral salt wasting C) Vasospasm causing delayed cerebral ischemia D) Hydrocephalus from CSF outflow obstruction
Answer: C
Rationale: Vasospasm is the most feared complication of SAH and classically presents with new focal neurological deficits and declining LOC developing days after the initial bleed — typically peaking at days 4–14. Elevated TCD velocities confirm developing vasospasm. Rebleeding (A) typically presents acutely with sudden severe headache and rapid LOC deterioration — not a gradual new focal deficit. Cerebral salt wasting (B) would present with hyponatremia and volume depletion, not focal motor deficits. Hydrocephalus (D) typically presents with LOC decline and gait instability rather than focal arm weakness. Understanding the SAH complication timeline is high-yield NCLEX content.
Question 5
A patient with an ischemic stroke is not receiving tPA. The patient’s blood pressure is 210/100 mmHg. The nurse is reviewing the orders. Which order would the nurse question?
A) Continuous cardiac monitoring B) IV labetalol 20 mg now and every 10 minutes PRN for SBP >220 C) IV nicardipine infusion titrate to keep SBP 160–170 mmHg D) Sequential compression devices to bilateral lower extremities
Answer: C
Rationale: In ischemic stroke patients not receiving tPA, permissive hypertension is the correct approach — the standard recommendation is to allow BP up to 220/120 mmHg without treatment. The elevated BP supports collateral perfusion of the ischemic penumbra. Actively lowering BP to 160–170 mmHg with a nicardipine infusion can reduce collateral flow and extend the infarct. Option B (treating only if SBP >220) is appropriate — it allows permissive hypertension while setting a safety ceiling. Cardiac monitoring (A) and SCDs for VTE prophylaxis (D) are both correct standard orders for acute stroke patients.
Question 6
A patient with acute ischemic stroke cannot swallow safely on bedside dysphagia screening. The patient has a prescribed oral statin and aspirin ordered. What is the correct nursing action?
A) Hold both medications until the patient passes the dysphagia screen B) Crush the aspirin, dissolve in water, and administer orally in small sips C) Hold the aspirin, consult pharmacy about IV or alternative formulation for the statin D) Notify the provider that the medications cannot be administered until discharge
Answer: A — with clinical nuance
Rationale: When a patient fails dysphagia screening, the correct nursing action is to maintain strict NPO status and hold all oral medications. No oral intake — including “small sips” of crushed medications — is permitted until the patient either passes the screen or receives formal SLP evaluation and dietary modification orders. For medications considered medically urgent (not the case for a statin on day 1), the nurse should contact the provider to discuss IV alternatives or nasogastric administration. Giving the aspirin in small sips (B) violates the NPO order and creates aspiration risk. Option C is partially correct in approach but incorrect in holding only aspirin — both oral medications are held. Option D misrepresents the situation — the provider should be notified for a treatment plan, but administration may resume as soon as the patient is cleared, not only at discharge.
Key takeaways for nursing students
- Time is brain. Know the treatment windows: tPA within 4.5 hours, thrombectomy up to 24 hours for selected patients. Every minute of delay costs ~1.9 million neurons.
- CT rules the decision tree. Hemorrhagic or ischemic? tPA is absolutely contraindicated in hemorrhagic stroke. All treatment planning flows from this single finding.
- Blood pressure management is stroke-type and treatment-dependent. Permissive hypertension (up to 220/120) in ischemic stroke without tPA; <185/110 before tPA; <180/105 after tPA; <140 systolic in ICH. Getting this wrong extends the injury.
- NIHSS is your trending tool. Change of ≥2 points = call the provider. Serial assessments matter as much as the initial score.
- Screen swallowing before anything by mouth. Dysphagia affects half of acute stroke patients. Aspiration pneumonia is common, preventable, and potentially fatal.
- Know your reversal agents by drug class. Warfarin → vitamin K + 4F-PCC. Dabigatran → idarucizumab. Factor Xa inhibitors → andexanet alfa.
- SAH has its own complication timeline. Vasospasm peaks at days 4–14. A stable day-2 patient can deteriorate on day 8.
- Rehabilitation starts in the acute phase. Early mobilization within 24–48 hours reduces DVT, pneumonia, and deconditioning when the patient is medically stable.
- Secondary prevention starts before discharge. Antiplatelets or anticoagulants (based on stroke mechanism), high-intensity statins, BP control, and lifestyle counseling are nursing education responsibilities.
For related neurological content, review the TBI nursing reference for traumatic brain injury comparisons, the meningitis nursing guide for infectious neurological emergencies, and the seizure nursing reference — post-stroke seizures and management overlap frequently in clinical practice. The head-to-toe assessment guide covers the full neurological exam that anchors stroke assessment at every phase of care.
