During mass-casualty incident triage, what should EMS primarily assess?

• A. Number of patients and their presenting symptoms and statements
• B. Vehicle models on the scene
• C. Brand of PPE
• D. Weather conditions

Answer: (A)

In mass-casualty incident triage, the priority is to rapidly determine how many patients there are and assess each person’s current condition based on their symptoms and ability to communicate. This quick counting and clinical snapshot lets responders categorize urgency and allocate limited resources to those most in need, aiming to maximize lives saved. Other factors like vehicle models on the scene, brand of PPE, or weather may affect safety and operations, but they do not provide the immediate information needed to decide who requires immediate care versus who can wait. The focus is on the number of patients and what their signs, symptoms, and statements reveal about their severity and survivability with treatment.
