What is the recommended action for a lifeguard if they observe someone at the poolside showing signs of cramps?

When a lifeguard observes someone at the poolside exhibiting signs of cramps, the recommended action is to provide them with fluids and monitor their condition. This approach is crucial because cramps, particularly in a swimming environment, can lead to further complications such as drowning or injury if not addressed promptly.

By offering fluids, the lifeguard helps to rehydrate the individual, which can alleviate muscle cramping. It's also important for the lifeguard to monitor the person closely, as cramps can escalate, potentially leading to more serious issues. This monitoring allows the lifeguard to assess the individual's recovery and take further action if necessary, such as calling for medical assistance.

Encouraging the individual to walk around or assisting them to the nearest exit may not be appropriate in this situation, as it could put additional strain on their muscles and worsen the cramping. Notifying other lifeguards may be necessary for additional support but does not directly address the immediate needs of the person in distress. Therefore, providing fluids and monitoring offers the most effective and timely response to alleviate the cramping and ensure safety.
