Guide to Emergency Nursing: Triage & Prioritization

Emergency Nursing: Order in Chaos

Emergency Nursing requires rapid decision-making in a high-pressure environment. It is the art of identifying who will die first without intervention. Unlike ward nursing where tasks are scheduled, the ER is unpredictable. Mastery of triage protocols and prioritization frameworks is essential to ensure patient safety when resources are outstripped by demand. This guide deconstructs the core competencies of emergency care, providing a robust framework for clinical practice.

The Emergency Nurses Association (ENA) emphasizes that effective triage reduces mortality and improves patient flow. Understanding the difference between “sick” and “not sick” is the first skill an ER nurse must develop.

The Emergency Severity Index (ESI)

The ESI is a five-level triage algorithm that categorizes patients based on acuity and resource needs.

Level 1: Resuscitation

Immediate life-saving intervention required. Patient is dying.
Examples: Cardiac arrest, massive trauma, severe respiratory distress (intubation needed).

Level 2: Emergent

High risk situation. Patient is confused, lethargic, or in severe pain/distress. Should not wait.
Examples: Chest pain (rule out MI), stroke symptoms, suicidal with plan, ectopic pregnancy.

Level 3: Urgent

Stable vital signs but requires multiple resources (labs, IV, imaging) to diagnose or treat. Can wait safely for a short period.
Examples: Abdominal pain, hip fracture, pneumonia.

Level 4: Less Urgent

Stable. Requires only one resource (e.g., stitches, x-ray only).
Examples: Simple laceration, ankle sprain.

Level 5: Non-Urgent

Stable. No resources needed (exam and prescription only).
Examples: Prescription refill, cold symptoms.

The Primary Survey (ABCDE)

Used for every trauma or critically ill patient to identify and treat life threats immediately.

• A – Airway: Is it patent? C-spine stabilization for trauma. Interventions: Suction, oral airway, intubation.
• B – Breathing: Rate, depth, effort. Interventions: Oxygen, bag-valve-mask, needle decompression (tension pneumothorax).
• C – Circulation: Pulse, color, skin temp, bleeding control. Interventions: IV access, fluids, blood products, CPR.
• D – Disability: Neurological status (GCS), pupils. Check blood glucose.
• E – Exposure: Remove clothing to inspect for hidden injuries. Prevent hypothermia.

The Secondary Survey (FGHI)

Once life threats are managed, a detailed head-to-toe assessment follows.
F – Full set of vitals / Family presence.
G – Give comfort measures (pain med).
H – History (AMPLE) / Head-to-toe.
I – Inspect posterior surfaces (log roll).

Recognizing Shock Syndromes

Shock is inadequate tissue perfusion. Rapid identification is critical to reverse organ failure.

• Hypovolemic Shock: Loss of fluid volume (blood or plasma). Signs: Tachycardia, hypotension, cool/clammy skin. Rx: Fluids, Blood.
• Cardiogenic Shock: Pump failure (MI, CHF). Signs: Pulmonary edema, JVD, hypotension. Rx: Inotropes (Dobutamine), Diuretics. Avoid fluid bolus.
• Distributive Shock: Massive vasodilation (Septic, Anaphylactic, Neurogenic). Signs: Warm skin (early septic), hives/stridor (anaphylactic). Rx: Vasopressors (Norepinephrine), Epinephrine, Fluids.

Prioritization Frameworks

When multiple patients need care, use these frameworks:

Mass Casualty Triage (START)

Used in disasters. Focus is doing the greatest good for the greatest number.
Red (Immediate): Life-threatening but treatable (e.g., airway obstruction, uncontrolled hemorrhage).
Yellow (Delayed): Serious but not immediately life-threatening (e.g., open fracture).
Green (Minor): Walking wounded.
Black (Deceased/Expectant): Dead or unsalvageable injuries (e.g., open skull fracture with brain matter exposed).

Standard ER Prioritization

Priority 1 (Life-Threatening): Airway compromise, shock, chest pain.
Priority 2 (Urgent): Severe pain, renal colic, displaced fractures.
Priority 3 (Non-Urgent): Chronic back pain, rashes.

Common ED Presentations

• Chest Pain: Immediate ECG (within 10 mins). MONA protocol (Morphine, Oxygen, Nitroglycerin, Aspirin) as indicated.
• Stroke: “Time is Brain.” Activate stroke code. CT scan to rule out bleed. TPA eligibility assessment.
• Sepsis: Lactate level, blood cultures, antibiotics, fluid resuscitation (30mL/kg).

Emergency Pharmacology (ACLS & RSI)

ER nurses must be proficient with high-risk medications used in codes and airway management.

• Epinephrine: Vasopressor for cardiac arrest and anaphylaxis.
• Amiodarone: Antiarrhythmic for V-tach/V-fib.
• Rapid Sequence Intubation (RSI): Sedative (Etomidate/Ketamine) followed immediately by a Paralytic (Succinylcholine/Rocuronium) to secure the airway. Never paralyze without sedation.

Legal and Ethical Issues

EMTALA (Emergency Medical Treatment and Labor Act): Federal law requiring anyone coming to an ED to be stabilized and treated regardless of their ability to pay.
Consent: Implied consent is used in emergencies for unconscious patients where family is absent and life is at risk.

Conclusion

Emergency nursing requires speed, accuracy, and calm under pressure. By mastering ESI triage and the ABCDE assessment, you become the safety net for patients in their most vulnerable moments.
