Ride the Wave to Success: YMCA Lifeguard Practice Test 2025 – Dive into Your Dream Job!

A prolonged gasp is a significant sign that a swimmer may be struggling and in need of assistance. This behavior often indicates that the individual is having difficulty breathing, potentially due to exhaustion, panic, or a water-related emergency. When a swimmer is unable to maintain proper body position and is gasping for air, it suggests that they are not able to stay afloat or swim effectively, heightening the risk of drowning.

In contrast, excessive waving might be a way for a swimmer to signal for help, but it can also be an expression of excitement or enjoyment in the water, which doesn't necessarily equate to a struggle. Surface swimming typically indicates that a swimmer is navigating the water without issues, while holding onto a pool float can mean that a swimmer is using it for support but may not inherently imply distress either. Recognizing the signs of a struggle, such as a prolonged gasp, is critical for lifeguards in ensuring the safety of all swimmers.
