A nurse is working in the emergency department when multiple patients arrive simultaneously. Which patient should the nurse assess first according to triage principles?

Emergency triage prioritizes life-threatening conditions. The patient with chest pain, diaphoresis, and shortness of breath shows signs of potential myocardial infarction requiring immediate assessment. Other patients have non-life-threatening issues like stable fractures or controlled bleeding.

Clinical Judgment This question assesses priority setting (Triage) and clinical judgment in an emergency situation. The key is determining "which patient is most likely to deteriorate rapidly and become life-threatening." The patient in option 2 shows severe chest pain, diaphoresis, and difficulty breathing and is anxious. These symptoms are classic signs of Acute Coronary Syndrome or Myocardial Infarction, requiring immediate evaluation and intervention. The other patients are stable, have controlled bleeding, or have severe pain but no immediate life threat. Memory Tip: Remember the "ABCs + potential for life threat." Patients with problems in Airway, Breathing, Circulation, or a very high likelihood of developing such problems, are the top priority. "Chest Pain + SOB + Diaphoresis" is a red flag for a cardiac emergency. KR vs US: The basic principle of emergency triage (prioritizing life-threatening situations) is the same in both Korea and the US. The NGN exam requires judgment based on a standardized US triage system (e.g., ESI). Korea primarily uses a 5-level triage system, but the core logic is identical.
