An MCI is an incident that strains response due to the number and severity of the casualties. Which elements are overwhelmed?

• A. Type of incident
• B. Weather conditions
• C. Number and severity of the casualties
• D. Distance to hospitals

Answer: (C)

In a mass-casualty incident, what challenges the system is the surge of patients and how severely they’re injured. The defining factor is whether the response resources—such as personnel, ambulances, field treatment areas, and hospital throughput—can keep up with that demand. When the number and severity of casualties exceed what the available resources can handle, those elements become overwhelmed. Weather, type of incident, or distance to hospitals can complicate response, but they do not define the scenario itself—the strain comes from the volume and gravity of injuries.
