Anxiety disorders are the most prevalent mental health conditions in the United States, affecting approximately 31% of adults at some point in their lives according to the National Institute of Mental Health. Nursing students will encounter patients with anxiety disorders in virtually every clinical setting — not just on psychiatric units. A patient’s undiagnosed social anxiety may interfere with your ability to obtain a complete history. A patient admitted for a cardiac workup may be experiencing panic attacks. A trauma survivor in the surgical unit may present with hyperarousal that complicates postoperative care.

This reference covers the five major anxiety disorders: generalized anxiety disorder (GAD), panic disorder, social anxiety disorder, PTSD, and OCD. For each, you will find DSM-5 diagnostic criteria, nursing assessment priorities, pharmacological and non-pharmacological interventions, and key nursing considerations. A cross-cutting nursing interventions section and medications table follow.


Quick reference: anxiety disorder comparison

DisorderCore featuresDiagnostic hallmarksFirst-line treatment
GADExcessive, uncontrollable worry about multiple life domains6+ months duration; 3+ of 6 somatic/cognitive symptomsSSRI or SNRI + CBT
Panic disorderRecurrent unexpected panic attacks + anticipatory anxietyAt least 1 month of persistent concern about future attacks or behavior changeSSRI + CBT (panic-focused)
Social anxiety disorderIntense fear of social situations where scrutiny may occurFear is out of proportion to actual threat; causes avoidance or endurance with distressSSRI or SNRI + CBT
PTSDIntrusion, avoidance, negative cognition/mood, hyperarousal after traumaSymptoms in all 4 clusters for 1+ month, causing impairmentSSRI (sertraline, paroxetine) + trauma-focused CBT or EMDR
OCDEgo-dystonic obsessions and/or compulsionsObsessions cause distress; compulsions are performed to reduce distress, not for pleasureSSRI (high dose) + CBT with ERP

Note: OCD is categorized separately from anxiety disorders in the DSM-5 (it falls under “Obsessive-Compulsive and Related Disorders”), but it is covered here because nurses frequently care for patients with OCD in psychiatric and general settings and the pharmacological management overlaps substantially.


Generalized anxiety disorder (GAD)

DSM-5 criteria

GAD requires excessive anxiety and worry about multiple events or activities, present more days than not for at least 6 months, which the person finds difficult to control. The worry must be associated with 3 or more of the following 6 symptoms (only 1 required for children):

  1. Restlessness or feeling keyed up or on edge
  2. Being easily fatigued
  3. Difficulty concentrating or mind going blank
  4. Irritability
  5. Muscle tension
  6. Sleep disturbance (trouble falling asleep, staying asleep, or restless, unsatisfying sleep)

Symptoms must cause clinically significant distress or functional impairment and must not be attributable to a substance, a medical condition, or another mental disorder.

Clinical presentation

Patients with GAD often present with somatic complaints — headaches, muscle tension, GI disturbance — before psychiatric symptoms are identified. They tend to be high utilizers of primary care. The worry content in GAD is broad and shifts between topics (finances, health, family, work), which distinguishes it from the more circumscribed worry of specific phobias or health anxiety.

Nursing assessment

  • Ask about the duration, content, and controllability of worry
  • Screen for somatic symptoms: headaches, GI complaints, chronic muscle tension
  • Assess sleep quality — insomnia is among the most distressing GAD symptoms
  • Use a validated screening tool such as the GAD-7 (scores ≥10 indicate moderate severity)
  • Assess functional impairment: is the patient avoiding responsibilities, withdrawing from relationships, or unable to work?
  • Screen for comorbid depression — GAD and MDD co-occur in approximately 60% of patients

Pharmacological interventions

SSRIs and SNRIs are first-line for GAD. Buspirone is an effective non-benzodiazepine anxiolytic appropriate for long-term GAD management — it takes 2–4 weeks to reach full effect, has no dependence risk, and does not impair cognition. Benzodiazepines may be used short-term for acute symptom relief but carry significant risks: tolerance, physical dependence, rebound anxiety, cognitive impairment, and fall risk in older adults. They are not recommended for long-term GAD management.

Non-pharmacological interventions

Cognitive behavioral therapy (CBT) is the gold-standard psychological treatment for GAD, with effect sizes comparable to medication. Relaxation techniques — progressive muscle relaxation, diaphragmatic breathing, mindfulness-based stress reduction — are useful adjuncts. Sleep hygiene education addresses the insomnia component.

Nursing priorities

  • Establish a calm, unhurried therapeutic relationship — time pressure worsens anxiety
  • Provide psychoeducation about the physical manifestations of anxiety
  • Teach and practice diaphragmatic breathing before discharge or procedures
  • Avoid false reassurance (“everything will be fine”) — acknowledge the patient’s experience
  • Monitor benzodiazepine use closely; taper rather than abrupt discontinuation

Panic disorder

DSM-5 criteria

Panic disorder is defined by recurrent unexpected panic attacks — abrupt surges of intense fear or discomfort reaching a peak within minutes — plus at least 1 month of:

  • Persistent concern or worry about additional panic attacks or their consequences (heart attack, losing control, “going crazy”), or
  • A significant maladaptive change in behavior related to the attacks (e.g., avoiding exercise, unfamiliar situations)

A panic attack itself requires 4 or more of 13 symptoms (palpitations, sweating, trembling, shortness of breath, chest pain, nausea, dizziness, chills/heat sensations, paresthesias, derealization/depersonalization, fear of losing control, fear of dying).

Panic attack vs. cardiac emergency

This differentiation is a high-yield nursing exam topic. Both panic attacks and acute coronary syndrome (ACS) can present with chest pain, shortness of breath, diaphoresis, and a sense of impending doom.

Key differentiating features favoring panic attack: younger age, no radiation of pain to arm/jaw, symptom peak within 10 minutes, prior history of panic attacks, normal ECG and troponin. However, you cannot clinically rule out a cardiac event. The nursing priority is to treat as a potential cardiac emergency until workup excludes it. Never dismiss chest pain as anxiety without objective data.

Interventions during acute panic

  • Stay with the patient; a calm, steady presence is therapeutic
  • Use a quiet, low-stimulation environment
  • Guide slow, controlled breathing — encourage breathing out fully to break the hyperventilation cycle
  • Speak in short, clear, calm sentences
  • Do not leave the patient alone until the attack resolves
  • Reassure the patient that panic attacks, though intensely uncomfortable, are not medically dangerous

Maintenance treatment

SSRIs are first-line for panic disorder maintenance. Cognitive behavioral therapy with a panic-focused protocol (including interoceptive exposure to bodily sensations) has strong evidence. Benzodiazepines may be used acutely but are not recommended for long-term management due to dependence risk.


PTSD

DSM-5 diagnostic criteria

PTSD requires exposure to actual or threatened death, serious injury, or sexual violence (directly experienced, witnessed, or learned about occurring to a close family member or friend). Symptoms must be present for more than 1 month, cause significant distress or functional impairment, and fall across all 4 of the following clusters:

Cluster B — Intrusion (1+ required): Intrusive memories, distressing dreams, dissociative flashbacks, intense psychological distress, or physiological reactivity to trauma-related cues.

Cluster C — Avoidance (1+ required): Avoidance of trauma-related thoughts/feelings or external reminders (places, people, activities, situations).

Cluster D — Negative alterations in cognition and mood (2+ required): Inability to recall key aspects of the trauma, persistent negative beliefs about self or world, distorted blame, persistent negative emotional states, diminished interest, feeling detached, inability to experience positive emotions.

Cluster E — Hyperarousal and reactivity (2+ required): Irritability/aggression, reckless behavior, hypervigilance, exaggerated startle response, concentration problems, sleep disturbance.

Trauma-informed care principles

Every nurse should understand trauma-informed care regardless of specialty. Core principles include: safety (physical and emotional), trustworthiness, choice, collaboration, and empowerment. Practical applications:

  • Explain all procedures before touching the patient
  • Ask permission before physical contact — “Is it okay if I take your blood pressure now?”
  • Avoid restraints unless there is an immediate safety risk
  • Do not ask patients to recount trauma details unless you are trained and it is therapeutically indicated
  • Be aware that common clinical triggers (loud environments, physical restraint, loss of control) can precipitate acute stress responses

Hyperarousal vs. avoidance: nursing implications

Hyperarousal symptoms (startle responses, hypervigilance, sleep disruption) are the cluster most visible to nurses on general units. These patients may appear irritable, suspicious, or non-compliant. The avoidance cluster — including emotional numbing and detachment — can make a patient seem disengaged or uninterested in their care. Recognizing these as PTSD symptom clusters rather than personality or behavioral problems is essential to safe, effective nursing care.

Pharmacology

SSRIs — specifically sertraline and paroxetine — are the only FDA-approved medications for PTSD. Prazosin, an alpha-1 blocker, has evidence for reducing trauma-related nightmares and is commonly used off-label for this indication. SNRIs (venlafaxine) are used as second-line agents. Benzodiazepines are generally avoided in PTSD — evidence suggests they may interfere with fear extinction and do not address the core PTSD symptom clusters.

Therapeutic approaches

Trauma-focused cognitive behavioral therapy (TF-CBT) and Eye Movement Desensitization and Reprocessing (EMDR) have the strongest evidence base for PTSD treatment. These are delivered by trained mental health providers, but nurses can support the therapeutic process by maintaining consistency, following through on commitments, and avoiding care approaches that undermine trust.


OCD

Obsessions vs. compulsions

Obsessions are recurrent, persistent, unwanted thoughts, urges, or images that cause marked anxiety or distress. The patient typically recognizes them as products of their own mind. Compulsions are repetitive behaviors or mental acts performed in response to obsessions or according to rigid rules — the goal is to reduce distress or prevent a dreaded event, not to produce pleasure.

The ego-dystonic nature of OCD distinguishes it from ego-syntonic conditions: the patient recognizes their obsessions as irrational or excessive and does not want them. This is a key distinction on NCLEX — if a patient describes their repetitive behavior as pleasurable or consistent with their values, OCD is less likely; consider a different diagnosis.

DSM-5 criteria

OCD requires the presence of obsessions, compulsions, or both. The obsessions or compulsions must be time-consuming (more than 1 hour per day) or cause clinically significant distress or impairment. Insight specifiers range from “good or fair insight” to “absent insight/delusional beliefs.”

Treatment

SSRIs at higher doses than used for depression or GAD are first-line pharmacological treatment for OCD. Commonly used agents include fluoxetine, fluvoxamine, sertraline, and paroxetine. The tricyclic antidepressant clomipramine is also FDA-approved and may be used when SSRIs are inadequate.

Cognitive behavioral therapy with Exposure and Response Prevention (ERP) is the gold-standard psychological treatment. ERP involves gradually exposing the patient to feared stimuli while preventing the compulsive response, allowing the anxiety to diminish naturally over time.

Nursing communication approach

Avoid accommodating compulsions (e.g., providing extra hand-washing supplies or rearranging the environment to align with rituals) unless clinically necessary — accommodation can reinforce the disorder. Set clear, consistent expectations while acknowledging the patient’s distress. Avoid power struggles over compulsive behaviors; focus on safety and maintaining therapeutic rapport. Be aware that hospitalization disrupts OCD routines and may precipitate significant distress.


Social anxiety disorder

Social anxiety disorder (also called social phobia) is defined by an intense, persistent fear of social situations in which the person may be scrutinized by others — conversations, meetings, eating in public, performing in front of others. The person fears they will act in a way that will be humiliating or embarrassing, or will show visible anxiety symptoms (trembling, sweating, stumbling over words).

The fear response is out of proportion to the actual threat, and the person typically recognizes this. Social situations are either avoided or endured with intense distress.

Why this matters for nursing

Social anxiety disorder has direct implications for how patients interact with healthcare providers. A patient with significant social anxiety may underreport symptoms, decline to ask questions, avoid follow-up appointments, or appear uncooperative when they are overwhelmed. Nurses who recognize social anxiety can adapt their communication approach: schedule longer appointment times, use written materials as supplements, avoid clinical settings that require public exposure, and validate the difficulty of healthcare interactions for these patients.

Treatment

SSRIs and SNRIs (particularly venlafaxine) are first-line for social anxiety disorder. CBT with an exposure component is the evidence-based psychological treatment. Beta-blockers (propranolol) may be used for situational performance anxiety (e.g., public speaking) but are not a treatment for generalized social anxiety disorder.


Nursing interventions across anxiety disorders

Regardless of the specific anxiety disorder, the following nursing priorities apply across the psychiatric and general clinical settings.

Establish a therapeutic relationship. Anxiety is worsened by perceived threat. A nurse who is calm, consistent, and transparent provides a corrective experience. Use your name, explain your role, and tell the patient what to expect before every intervention.

Use a calm, measured tone and pace. Mirror the emotional state you want to encourage. Speaking slowly and quietly, sitting rather than standing, and reducing ambient noise all reduce autonomic activation.

Avoid reinforcing avoidance. In anxiety disorders, avoidance reduces distress in the short term but maintains and worsens anxiety over time. While respecting patient autonomy, gently encourage gradual engagement rather than wholesale avoidance of feared stimuli (e.g., encourage a patient with social anxiety to interact with the care team rather than communicating only in writing).

Medication teaching. Patients on SSRIs for anxiety need to understand that full therapeutic effect takes 4–6 weeks and that anxiety may transiently worsen in the first 1–2 weeks of treatment — a common reason for early discontinuation. Patients on benzodiazepines require clear education about dependence risk and the importance of not abruptly stopping.

Safety assessment. All anxiety disorders carry elevated suicide risk relative to the general population — this is highest in PTSD, panic disorder, and OCD with contamination obsessions. Conduct a baseline safety assessment and reassess when symptoms worsen.

Document functional impairment. Anxiety symptoms that seem subclinical on a screening tool may cause significant impairment in work, relationships, and self-care. Functional impact is a critical component of the nursing assessment and informs treatment intensity.


Medications used in anxiety disorders

Drug classExamplesUse in anxietyKey nursing considerations
SSRIsSertraline, escitalopram, paroxetine, fluoxetine, fluvoxamineFirst-line for GAD, panic disorder, PTSD, OCD, social anxiety4–6 weeks to full effect; anxiety may worsen initially; monitor for suicidal ideation in patients under 25; do not stop abruptly; risk of serotonin syndrome if combined with other serotonergic agents
SNRIsVenlafaxine, duloxetineFirst-line for GAD and social anxiety; second-line for PTSDSame serotonin syndrome precautions as SSRIs; monitor blood pressure (venlafaxine causes dose-dependent BP elevation); taper on discontinuation to avoid discontinuation syndrome
BuspironeBuspirone (BuSpar)GAD — long-term managementNon-addictive; no immediate anxiolytic effect (takes 2–4 weeks); does not treat acute panic; ineffective for patients who have previously used benzodiazepines (reduced response); no withdrawal syndrome
BenzodiazepinesLorazepam, diazepam, clonazepam, alprazolamShort-term or acute anxiety relief; acute panic; procedural anxietySignificant dependence and tolerance risk; CNS depression — monitor for sedation, respiratory depression, falls; do not use in patients with substance use disorders or history of benzodiazepine dependence; taper slowly to discontinue; contraindicated in pregnancy (Category D)
TCAsClomipramineOCD (FDA-approved); panic disorderAnticholinergic effects (dry mouth, urinary retention, constipation, blurred vision); cardiac conduction effects — ECG monitoring recommended; highly lethal in overdose (narrow therapeutic index)
Alpha-1 blockersPrazosinPTSD nightmaresOff-label use; monitor for orthostatic hypotension — instruct patient to rise slowly; first dose at bedtime to reduce hypotension risk
Beta-blockersPropranololSituational performance anxietyReduces peripheral manifestations of anxiety (tremor, palpitations) but not subjective fear; contraindicated in asthma and COPD; not for generalized anxiety disorder

NCLEX tips: anxiety disorders

Priority action for acute panic attack: Stay with the patient, use a calm presence, and guide breathing. Do not leave, do not administer medication without an order, and do not demand the patient “calm down” or explain their symptoms.

Differentiating OCD from other anxiety disorders: The ego-dystonic nature is the key exam concept — the patient does not want the obsessions and finds them distressing. Compare this to a patient with schizophrenia who may have similar-sounding intrusive content but does not recognize it as irrational.

Medication onset timing: NCLEX questions frequently test knowledge of when medications begin working. SSRIs take 4–6 weeks for full anxiolytic effect. Buspirone takes 2–4 weeks. Benzodiazepines act within 30–60 minutes.

Benzodiazepine priority concern: The NCLEX priority nursing concern for benzodiazepines is respiratory depression, particularly when combined with other CNS depressants (opioids, alcohol).

Panic attack vs. ACS: Never assume chest pain is anxiety without ruling out cardiac causes — this is a patient safety and exam priority. Obtain ECG and cardiac markers; treat as cardiac emergency until the workup is complete.

PTSD trauma-informed care: Common exam scenario — nurse needs to explain a procedure to a PTSD patient. The correct priority action is to explain what you are going to do and ask permission before touching. Do not restrain unless there is immediate safety risk.
