YMCA Lifeguard Practice Test

Which vital sign should be checked first when assessing an unconscious individual?

1. Blood pressure

2. Pulse

3. Respiration rate

4. Body temperature

The correct answer is: Pulse

Checking the pulse is crucial when assessing an unconscious individual because it provides immediate information about the person's circulatory status. The pulse indicates whether the heart is beating and can help determine if the individual has adequate blood flow to vital organs. In an emergency situation, restoring circulation is often a priority, so knowing if there is a detectable pulse informs the rescuer whether they need to initiate cardiopulmonary resuscitation (CPR) or other interventions. While respiration rate, blood pressure, and body temperature are important vital signs, they are typically assessed after checking the pulse in an unconscious patient. The pulse offers a direct indication of both heart function and overall circulation, making it the most critical initial sign to check in this scenario.
