Which of the following is required for effective triage during a mass casualty event?

Effective triage during a mass casualty event is essential for ensuring that resources are allocated efficiently to those in greatest need of immediate medical attention. The primary goal of triage is to quickly assess and classify patients based on the severity of their injuries and the urgency of their medical needs.

A rapid assessment of severity and need for care allows first responders to prioritize patients, ensuring that those with life-threatening conditions receive immediate treatment. This process typically involves evaluating vital signs, level of consciousness, and apparent injuries to determine which patients can safely wait for care and which require immediate intervention.

In contrast, while patient age assessment, victim’s clinical history, and location of injury may provide useful information, they are not as critical as the overall assessment of a patient's current medical status and immediate care needs. These factors can guide treatment decisions but do not directly impact the urgency of triage, which focuses on the rapid identification of those who require prompt medical attention.
