Water Safety Instructor (WSI) Practice Exam

The presence of signs such as struggling to stay afloat and slow movement is a clear indication of swimmer exhaustion. When individuals are fatigued, their body strength decreases, leading to difficulty in maintaining their position in the water. This struggle can manifest as frequent attempts to keep the head above water, erratic movements, and a noticeable reduction in the speed of their swimming. Observing a swimmer who is moving slowly or unable to effectively tread water can indicate that they are in distress and may need immediate assistance. Recognizing these signs is crucial for ensuring safety in aquatic environments and provides an opportunity for intervention before exhaustion escalates to a more dangerous situation.

In comparison, excessive splashing and laughter are often associated with enjoyment rather than exhaustion. Perfect swimming form indicates a swimmer who is skilled and likely not exhibiting signs of fatigue. Similarly, a swimmer moving away from the pool edge may not convey any signs of exhaustion; instead, this could be a choice made in play or exploration. Understanding the clear signs of swimmer exhaustion allows instructors and lifeguards to respond appropriately to ensure the safety of all participants in the water.
