What constitutes a Rescue in the context of lifeguarding?

In the context of lifeguarding, a rescue is defined as an intervention that occurs when a guest cannot reach the surface of the water by themselves, typically due to distress or an emergency situation. This condition necessitates direct action from a lifeguard to ensure the safety of the individual. The primary function of a lifeguard is to monitor and respond effectively to situations where a guest is at risk of drowning or is otherwise in danger in the water.

The other options highlight aspects of lifeguarding duties or interactions with guests but do not represent the critical action required to save someone in distress. Minimal assistance, for example, does not equate to a rescue, as it implies that the guest is still somewhat able to manage their situation independently. Observing the area and communicating directions are important lifeguard responsibilities, but these actions alone do not involve the direct intervention that a rescue entails. Therefore, the scenario in which a guest is unable to reach the pool surface clearly represents the urgent need for a lifeguard to execute a rescue.
