Which step is NOT part of evaluating a casualty?

Evaluating a casualty involves a systematic approach to assess their condition and to provide appropriate care. Checking for responsiveness, pulse, and bleeding are all crucial components of this assessment.

When assessing responsiveness, you determine if the person is awake or can respond to stimuli. This step helps you gauge the level of consciousness and immediate needs. Checking for a pulse is essential to understand if there’s any circulation; it informs you about the victim's vital signs and overall cardiovascular health. Additionally, evaluating bleeding is critical because it can quickly lead to shock or other life-threatening issues if not addressed promptly.

In contrast, checking for age does not directly inform the immediate medical assessment in the same way the other steps do. While understanding a casualty's age may be relevant in some contexts (like dosage for medications or potential complications), it is not a fundamental step in the immediate evaluation of a casualty's condition. Therefore, it is not part of the essential steps taken when assessing a casualty in an emergency situation.
