Emergency Nursing & Triage for NCLEX: ESI System, Mass Casualty & Disaster Response
Master emergency nursing and triage for the NCLEX. Covers the ESI triage system, mass casualty incidents, disaster triage, and priority assessment.
Emergency Nursing and Triage for NCLEX
Emergency nursing and triage concepts are tested on the NCLEX to assess your ability to prioritize care in acute situations. Understanding triage systems and disaster response protocols is essential for safe practice.
Emergency Severity Index (ESI)
The ESI is a five-level triage system used in most emergency departments. ESI Level 1 (Resuscitation): Immediate life-threatening condition requiring aggressive intervention (cardiac arrest, severe respiratory distress, active hemorrhage). ESI Level 2 (Emergent): High-risk situation, confused/lethargic/disoriented, or severe pain/distress (chest pain with diaphoresis, stroke symptoms, severe allergic reaction). ESI Level 3 (Urgent): Requires two or more resources but vital signs are stable (abdominal pain requiring labs and imaging, lacerations requiring sutures). ESI Level 4 (Less Urgent): Requires one resource (simple laceration, prescription refill). ESI Level 5 (Non-Urgent): Requires no resources (medication refill, minor complaint).
Mass Casualty Triage
In mass casualty incidents, the triage approach shifts from individual-focused to population-focused care. The goal is to save the greatest number of lives with available resources. The START triage system (Simple Triage and Rapid Treatment) uses four categories. Red (Immediate): Life-threatening injuries that are survivable with immediate treatment. Yellow (Delayed): Serious injuries that can wait for treatment. Green (Minor): Walking wounded with non-life-threatening injuries. Black (Expectant): Dead or injuries incompatible with survival given available resources. This represents a significant ethical shift from everyday practice where every effort is made to save every patient.
Disaster Response Nursing
Know your facility disaster plan and your role within it. Understand the incident command system (ICS) structure. Triage patients using appropriate mass casualty criteria. Document using disaster documentation methods. Maintain personal safety and use appropriate PPE. Practice surge capacity principles including early discharge of stable patients and canceling elective procedures.
Priority Assessment in Emergencies
Always follow ABCs: secure the airway first, then assess breathing and circulation. Use a primary survey (ABCDEs) for rapid assessment and a secondary survey for head-to-toe evaluation. Review with our clinical nursing mini-exams and emergency nursing topics.
