In the emergency department, four patients arrive simultaneously. Applying the ABC (airway, breathing, circulation) priority framework, which patient should the nurse assess first?
- AA 30-year-old with a closed forearm fracture and intact distal pulses
- BA 22-year-old with a 4 cm superficial laceration and controlled bleeding
- CA 45-year-old with an audible stridor and increasing facial swelling after eating shellfish
- DA 68-year-old with a two-day history of dysuria and low-grade fever
Show the answer and why the others fail
Answer: C. A 45-year-old with an audible stridor and increasing facial swelling after eating shellfish
- A
- A closed fracture with intact neurovascular status is urgent but stable and can safely wait.
- B
- Controlled bleeding from a superficial wound poses no immediate threat to life.
- C — correct
- Stridor with rapidly progressing facial swelling signals impending airway obstruction from anaphylaxis. Airway compromise always takes highest priority and requires immediate intramuscular epinephrine.
- D
- No airway, breathing, or circulatory compromise is reported for this patient, so under the ABC framework the presentation ranks below airway obstruction. This does not make the patient low priority overall — older adults with urinary symptoms and fever require prompt vital signs and mental status assessment, because urosepsis is easily missed in this group.
TakeawayTriage follows airway, breathing, circulation — stridor with progressing angioedema outranks every stable injury in the queue.
