During a mass casualty incident, which measure is not typically performed during the primary survey?

In the context of a mass casualty incident, the primary survey is a critical initial assessment that focuses on identifying and addressing immediate life-threatening conditions. The primary survey follows the ABCDE approach, which stands for Airway, Breathing, Circulation, Disability, and Exposure.

Determining psychological state, while important in the overall management of a patient, is not part of the primary survey. Instead, it falls within the broader assessment and management phase that occurs after immediate life-threatening issues are addressed. In a mass casualty scenario, the priority must be placed on physical conditions that can rapidly affect survival, such as ensuring the airway is clear, assessing respiration, and checking circulation to maintain blood flow and prevent shock.

Therefore, the correct answer captures the understanding that the primary survey focuses exclusively on physical and immediate life-threatening assessments, leaving psychological evaluations for later in the emergency care process.
