Written Lifeguarding Practice Test 2025 - Free Lifeguard Practice Questions and Study Guide

When a lifeguard encounters a swimmer who is unresponsive, the most appropriate immediate action is to call for assistance and begin rescue protocols. This is crucial because an unresponsive swimmer may be in distress and could require immediate lifesaving measures. Alerting other lifeguards ensures that additional support is on the way, which can be vital in emergency situations. Starting rescue protocols enables the lifeguard to focus on the safety and welfare of the swimmer, increasing their chances of survival.

Initiating rescue protocols may include entering the water to retrieve the swimmer if safe to do so, monitoring their airway, or preparing for CPR while waiting for emergency medical services to arrive. This prompt response is essential to mitigate potential drowning incidents, as time is of the essence in such emergencies.

Other actions, such as submerging the swimmer to check for a reaction or continuing to scan the area, would not effectively address the critical situation at hand and could hinder the swimmer’s chances of receiving timely help. Waiting until the swimmer surfaces is likewise counterproductive, as the lifeguard’s priority must be to ensure the swimmer's safety without delay.
