What should lifeguards ensure when a rescuer is entered into the water for a distressed swimmer?

When a lifeguard enters the water to assist a distressed swimmer, it is crucial for them to keep the path clear for the rescuer and maintain effective communication. This ensures that the rescuer can reach the swimmer quickly and safely without any impediments. A clear path is vital as it eliminates obstacles that could potentially slow down or hinder the rescue mission, allowing for a swift response, which can be critical in emergencies where time is of the essence.

Additionally, effective communication between lifeguards on duty is key to coordinating the rescue effort. By providing updates on the situation and directing attention as necessary, lifeguards can optimize their response, ensuring that everyone involved is aware of the actions being taken and any changes in the situation.

The other choices do not align with the necessary actions during a rescue. Dropping rescue equipment would leave the rescuer vulnerable and less equipped to handle the situation. Positioning elsewhere or merely observing without interfering fails to support the rescuer effectively, which could delay the timely assistance that a distressed swimmer desperately needs.
