If a lifeguard encounters an unconscious victim, what should be their first action?

The first action a lifeguard should take when encountering an unconscious victim is to check for responsiveness. This initial assessment is crucial as it helps to determine the state of the victim and guides the subsequent steps in providing assistance. Checking responsiveness allows the lifeguard to evaluate if the victim is breathing and to assess the level of consciousness. If the victim does not respond, the lifeguard can then proceed to call for emergency services and perform lifesaving measures like CPR if necessary.

Other options like calling for emergency services, evacuating the pool area, or performing a safety assessment are important actions but are typically initiated after confirming the level of responsiveness. Knowing whether the victim is conscious or unconscious influences the urgency and type of response required, making the assessment of responsiveness the priority.
