Which of the following positions is NOT one of the four MCI priority positions?

The correct choice is rooted in the understanding of the four priority positions used in mass casualty incidents (MCI). In this context, the triage position is essential for assessing and categorizing victims based on the urgency of their medical needs. The transport position coordinates the movement of patients from the scene to medical facilities, ensuring a systematic approach to care. Ambulance staging involves strategically positioning ambulances to optimize their availability and response times, allowing for efficient transport.

Emergency rollout, while possibly relevant in other emergency contexts, does not specifically represent one of the established positions in standard MCI operations. Recognizing this distinction is critical for effective incident management during mass casualty events. Understanding these positions helps ensure that the response is well-organized and that patient care is prioritized appropriately, ultimately saving lives and improving outcomes in chaotic situations.
