What action should be taken if a patron shows signs of distress in the water?

In situations where a patron shows signs of distress in the water, alerting the lifeguard and monitoring the situation is the most appropriate action to take. Lifeguards are trained professionals equipped with the skills necessary to assess and address emergencies effectively. By alerting the lifeguard, you ensure that a trained individual can respond quickly, potentially rescuing the patron while also ensuring the safety of others in the vicinity.

Monitoring the situation while waiting for the lifeguard allows for better awareness of any changes in the patron's condition, which can be critical in assessing whether further action might be needed. This approach prioritizes safety and supports the lifeguard's role in managing the situation effectively.

Other options might seem reasonable but can lead to increased risk. Diving in immediately could endanger both the rescuer and the distressed individual if proper techniques are not used. Waiting to see if the distress continues can waste valuable time, potentially leading to a more serious outcome. Instructing the patron to swim back may not be feasible if they are truly in distress, as they may not have the energy or ability to do so safely. Hence, the recommended course of action is to alert the lifeguard who can provide the appropriate assistance.
