A public health nurse is preparing for a mass casualty incident. Which of the following tasks should the nurse complete during the planning phase of disaster management?

A. Make referrals to support services: Referrals to social, medical, or mental health support are part of the response and recovery phases, focusing on addressing ongoing client needs after the disaster occurs, rather than planning. B. Coordinate care in shelters: Coordinating care in shelters is an activity performed during the response phase, when the disaster has already occurred and immediate client needs must be addressed. It is not part of pre-event planning. C. Triage injured individuals: Triage occurs during the response phase to prioritize treatment based on injury severity. This action is reactive to actual casualties and is not part of the planning phase. D. Participate in practice drills: Engaging in disaster preparedness drills is a key component of the planning phase. Drills help identify gaps in emergency protocols, improve staff readiness, and ensure effective coordination during an actual mass casualty incident.
