What are the signs of a distressed swimmer?

A distressed swimmer typically exhibits signs of struggle and an inability to stay afloat. The correct choice highlights specific behaviors such as waving for help and showing difficulty in maintaining their position in the water, which are classic indicators of distress. When a swimmer is in trouble, they may not be able to call out verbally and instead will use visual signals, like waving, which demonstrates that they are seeking assistance. Recognizing these signs is crucial for lifeguards and others nearby, as it allows for a timely and effective response.

Other options, while possibly indicative of another state, do not suggest distress. For instance, calmly swimming on their back or swimming easily with a smile signifies that the individual is comfortable and in control. Floating motionless could indicate a range of situations but does not explicitly indicate distress without additional context. Understanding these distinctions is essential for recognizing when immediate action is necessary to assist swimmers in trouble.
