What should a lifeguard do if they notice a swimmer struggling?

When a lifeguard notices a swimmer struggling, the most appropriate action is to initiate a rescue as needed. This response is based on the lifeguard's training, which emphasizes the importance of quick and decisive action to prevent drowning incidents and ensure swimmer safety.

A struggling swimmer can quickly become overwhelmed, and immediate intervention can make the difference between a successful rescue and a potential emergency situation. The lifeguard has the skills and equipment necessary to perform a rescue safely and effectively, whereas patrons nearby may not have the training or knowledge to assist appropriately.

Continuing to remain on duty without alerting anyone overlooks the responsibility to intervene actively in a situation where someone's life may be at risk. Asking nearby patrons for help may delay the rescue, potentially putting the swimmer in greater danger. Lastly, ignoring the situation unless the swimmer asks for help neglects the lifeguard's duty to monitor and ensure the safety of all swimmers, as many individuals may not have the capacity to call for help when struggling. Thus, initiating a rescue is the necessary and trained response to address a swimmer in distress promptly.
