Boy Scouts of America (BSA) Lifeguard Practice Test 2025 - Free Lifeguard Practice Questions and Study Guide

A lifeguard can recognize a swimmer at risk of drowning by observing unusual behaviors, such as clinging to the edge of the pool or waving their arms frantically. These actions are often indicators of distress and suggest that the swimmer is struggling to stay afloat or is having difficulty with their swimming abilities. Lifeguards are trained to identify these signs, as they may signal that a swimmer is unable to call for help or may be panicking.

While monitoring water temperature and visibility provides important information regarding safety, these factors do not directly indicate a swimmer's distress. Similarly, counting the number of swimmers in the area does not help determine individual swimmer capabilities or condition. Lastly, ensuring swimmers wear flotation devices can enhance safety, but it does not guarantee that a swimmer is not in distress, as even those with flotation aids can experience problems in the water. Thus, recognizing unusual behaviors is the most effective method for a lifeguard to assess a swimmer's risk of drowning.
