Trauma and emergency nursing reference: assessment, priorities, and interventions

Emergency and trauma nursing requires a different kind of clinical thinking than floor nursing. Patients arrive undifferentiated — you don’t know their history, their medications, or what’s killing them. Your job is to stabilize fast, identify threats to life in priority order, and act before a full picture is available. The margin for error is narrow and the pace is unrelenting.

This reference covers the clinical frameworks emergency nurses use every shift: the primary survey (ABCDE), Emergency Severity Index triage, secondary survey, common emergency presentations, trauma-specific interventions, critical medications, and handoff communication. It is designed for nursing students entering the ED or preparing for NCLEX scenarios involving emergency care. Use it alongside the ICU critical care nursing reference, sepsis nursing guide, head-to-toe assessment guide, and ABG interpretation reference.

Primary survey (ABCDE): the first five minutes

The primary survey is the structured, sequential assessment used in every trauma and emergency patient. It identifies immediately life-threatening conditions in priority order. Based on ATLS (Advanced Trauma Life Support) and TNCC (Trauma Nursing Core Course) guidelines, the ABCDE framework governs the first minutes of any resuscitation. You do not move to the next letter until the current one is addressed.

After the primary survey, immediately reassess. Anything that deteriorates returns you to the beginning of ABCDE.

Triage: ESI levels 1–5

The Emergency Severity Index (ESI) is the five-level triage system used across most US emergency departments. It was developed to sort patients by acuity and resource needs, not simply by chief complaint. ESI version 4 is the current standard and is validated for use with adults and children. Triage decisions are made within minutes of arrival based on clinical presentation, vital signs, and anticipated resource utilization.

Triage is not a one-time event. Patients in the waiting room can deteriorate — re-triage is indicated any time a patient reports a significant change, or appears changed on visual check.

Secondary survey

The secondary survey begins only after the primary survey is complete and life-threatening problems are addressed or controlled. This is the systematic head-to-toe assessment aimed at identifying all injuries or findings that were not immediately life-threatening. In trauma, this typically occurs in the resuscitation bay while monitoring continues.

SAMPLE history

Collect SAMPLE history from the patient, family, EMS, or bystanders:

• S — Symptoms: chief complaint, onset, character
• A — Allergies: medications, contrast, latex, environmental
• M — Medications: current medications, last dose, anticoagulants (critical in trauma)
• P — Past medical and surgical history
• L — Last oral intake (time, what was consumed — critical pre-intubation)
• E — Events leading to presentation (mechanism of injury or precipitating event)

In trauma, mechanism of injury is as important as vital signs. High-speed MVC, fall from height, penetrating trauma to trunk, blast injury, and pedestrian-versus-vehicle all predict injury patterns. EMS handoff — including scene findings, interventions already performed, and any changes in transit — is mandatory information.

AMPLE mnemonic (trauma-specific variation)

Allergies, Medications, Past medical history / Pregnancy, Last meal, Events or mechanism of injury. Some institutions use AMPLE and SAMPLE interchangeably; the content overlaps substantially.

Head-to-toe physical assessment

Work head to toe, examining every region. In trauma, look specifically for:

• Head/face: Raccoon eyes or Battle’s sign (basilar skull fracture), hemotympanum, facial instability
• Neck: Tracheal position, JVD, midline tenderness, cervical collar in place until clearance
• Chest: Rib tenderness, paradoxical movement, subcutaneous emphysema (crepitus)
• Abdomen: Distension, involuntary guarding, seat-belt sign (bruising across abdomen — associated with bowel and lumbar spine injury)
• Pelvis: Gently compress iliac wings once — instability suggests pelvic fracture (do not repeatedly compress — it dislodges clot)
• Extremities: Pulses, deformity, sensation, motor function distal to any suspected fracture
• Posterior: Log roll to inspect entire back, flanks, buttocks, and perianal region

Refer to the head-to-toe nursing assessment guide for a complete systematic framework you can apply in both the ED and clinical rotations.

Common emergency presentations and nursing priorities

Trauma-specific interventions

Massive transfusion protocol (MTP)

MTP is activated when a patient requires large-volume blood product resuscitation — typically defined as 10+ units of packed red blood cells (PRBCs) within 24 hours, or anticipated need for rapid high-volume replacement. The protocol provides PRBCs, fresh frozen plasma (FFP), and platelets in a fixed ratio (commonly 1:1:1) to approximate whole blood and prevent dilutional coagulopathy. Nursing responsibilities include: activating the protocol with the blood bank, transporting and hanging products rapidly, monitoring for transfusion reactions, tracking product volumes, and monitoring temperature (transfused blood is cold — use warmers).

Cryoprecipitate is added to correct fibrinogen depletion. Tranexamic acid (TXA) is administered within 3 hours of injury to reduce fibrinolysis (CRASH-2 trial evidence). Calcium chloride or gluconate is given to counteract the citrate in stored blood products, which chelates ionized calcium and causes hypocalcemia, worsening cardiac function.

Damage control resuscitation (DCR)

DCR is the philosophy of restoring physiology rather than anatomy in the initial phase of trauma resuscitation. The “lethal triad” of trauma — hypothermia, acidosis, and coagulopathy — are mutually reinforcing and rapidly fatal. DCR aims to break the cycle by:

• Using blood products (not crystalloid) as the primary resuscitation fluid
• Correcting hypothermia aggressively (warm blankets, warmed IV fluids, warm environment)
• Accepting permissive hypotension (MAP 50 mmHg, systolic 80–90 mmHg) in penetrating trauma until surgical hemorrhage control is achieved — over-resuscitation dilutes clotting factors and raises pressure at the injury site, dislodging forming clots

Permissive hypotension

In penetrating trauma with ongoing hemorrhage, targeting a lower-than-normal blood pressure (systolic 80–90 mmHg) prior to definitive hemorrhage control is supported by evidence. The goal is to maintain enough perfusion pressure to preserve brain and heart function without dislodging clots at the bleeding site. This does NOT apply in traumatic brain injury — TBI patients require MAP ≥80 mmHg to maintain cerebral perfusion pressure.

Tourniquet use

Tourniquets are first-line for life-threatening extremity hemorrhage. The “Stop the Bleed” campaign and military data from Iraq and Afghanistan have established that proper tourniquet application saves lives and that the historical concern about tourniquet-related limb loss was overstated when application time is documented and the tourniquet is released within several hours at definitive care. Nursing responsibilities: document time of application, do not remove in the ED (surgical team decision), assess distal neurovascular status, and monitor for signs of compartment syndrome.

C-spine precautions

Any mechanism of injury with the potential for spinal column damage — including MVC, fall from height, diving injury, contact sports, and penetrating trauma near the spine — warrants cervical immobilization until cleared by clinical criteria (NEXUS criteria or Canadian C-Spine Rules) or imaging. Nursing responsibilities: maintain inline stabilization during any patient movement, log roll for posterior examination, ensure collar fit and skin integrity, and document neurological assessment (motor and sensory) in all four extremities.

Emergency medications nurses must know

Documentation and handoff in the ED

SBAR in the emergency context

The SBAR communication framework is standard for structured handoff. In the ED, SBAR must be fast, specific, and anticipatory:

• Situation: “I have a 52-year-old male, GSW to the left chest, BP 78/40, GCS 12, intubated in the field.”
• Background: “Arrived 4 minutes ago by EMS. Last known well was 30 minutes ago. One large-bore IV in right AC. 500mL NS running. Tourniquet to left thigh for co-existing extremity wound.”
• Assessment: “Suspected hemothorax and hemorrhagic shock. Left breath sounds absent.”
• Recommendation: “Requesting trauma surgery activation, chest tube set at bedside, MTP activation, and stat portable CXR.”

Time-sensitive documentation

In the ED, time is not just important — it is a clinical and legal record. Document:

• Triage time and ESI level assigned
• Time of patient placement in room
• Time of first provider assessment
• Time of every intervention (IV, medication, procedure) to the minute
• Any procedures: indication, consent (or exception), equipment used, patient response, complications
• Reassessments after every intervention and at regular intervals
• All communication with providers: who, what, and when

In trauma, documentation of mechanism of injury, prehospital interventions, tourniquet time, and blood products administered is transmitted with the patient to the OR, ICU, or receiving facility. Incomplete documentation creates clinical risk.

Trauma team communication

Trauma activations involve simultaneous, overlapping clinical activity. The trauma team leader directs the room while nursing manages specific tasks. Role assignments are made before the patient arrives. Every nurse in the room has a defined role: airway, IV/medications, documentation, family support, and runner. Closed-loop communication — repeating back every order before executing it — is mandatory in this environment. If you receive an order and don’t understand it, say so immediately. There is no room for ambiguity when the patient is exsanguinating.

Common mistakes and pitfalls for nursing students in the ED

Anchoring on the first diagnosis. The first assumption about a patient’s presentation can be wrong. A confused elderly patient assumed to be “sundowning” may be septic. An anxious patient with shortness of breath dismissed as “panic” may be in pulmonary embolism. Stay open to evolving assessment data.

Skipping reassessment. The primary survey is not a one-time event. A patient who was stable ten minutes ago can deteriorate rapidly. Reassess after every intervention and every significant time interval.

Underestimating the elderly patient. Older adults may not mount the expected tachycardic response to hemorrhage if they take beta-blockers. Their blood pressure may appear adequate until they are in severe shock. Normal vital signs in a compromised elderly trauma patient are not reassuring.

Delaying epinephrine in anaphylaxis. Reaching for diphenhydramine first is a common student error. Epinephrine IM is the only drug that treats the life-threatening components of anaphylaxis. Antihistamines treat the itch.

Not communicating deterioration early enough. In the ED, nurses see the patient continuously; providers often do not. If something about a patient’s condition worries you, escalate promptly and specifically. State what you observed, when you observed it, and what concerns you.
