A nurse is working in the emergency department when multiple patients arrive simultaneously following a multi-vehicle accident. Which patient should the nurse prioritize for immediate assessment and treatment?

The patient with an open femur fracture, hypotension, tachycardia, and altered mental status represents the highest priority emergency requiring immediate intervention to prevent death.

This question assesses the principles of triage in the emergency department and the ability to determine priorities. An emergency room nurse must quickly identify the patient whose life-saving treatment is most urgent when multiple patients arrive simultaneously.

The correct answer, patient 1, is a 45-year-old with an open femur fracture, hypotension (90/60 mmHg), tachycardia (120 beats/min), and altered consciousness. This is a life-threatening situation that should be classified as a first-priority (emergent) patient. An open femur fracture can cause 1-2 liters of bleeding, and the hypotension and tachycardia suggest hemorrhagic shock. The altered consciousness indicates decreased brain perfusion, with a risk of cardiovascular collapse and death without immediate treatment.

The triage system prioritizes patients based on the severity of their condition and the urgency of treatment. First-priority patients require immediate life-saving interventions and may die if treatment is delayed. This patient needs immediate intravenous access, fluid resuscitation, blood typing and crossmatching, orthopedic consultation, and surgical preparation.

Patient 2 has multiple superficial lacerations but stable vital signs and clear consciousness, placing them at priority 2-3. Patient 3 has chest pain and dyspnea but stable vital signs and an oxygen saturation of 95%, indicating a low immediate life threat. Patient 4 has a suspected wrist fracture with pain but is not in a life-threatening condition.

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.

Clinical Practice Guide If a patient with an open fracture shows signs of shock, the following must be performed immediately: 1) secure two large-bore IV lines (14-16G), 2) fluid resuscitation (usually normal saline), 3) apply direct pressure to the bleeding site, 4) prepare for blood type testing and crossmatching, 5) administer broad-spectrum antibiotics (infection prevention), 6) review tetanus prophylaxis. Caution: In SATA (Select All That Apply) questions, "Which patient should be seen first?" and "Which intervention should be done first?" are different. Since this question asks about 'patient priority,' select the patient with a life-threatening condition. If it asks about 'intervention priority,' even for the same patient, securing the airway (ABC) may come before dressing the bleeding site.
