What is the best action to take after rescuing a guest from the pool?

After rescuing a guest from the pool, the most appropriate action is to check for responsiveness and provide care. This step is crucial because it allows the lifeguard to assess the condition of the guest and determine if they require immediate medical attention. Checking responsiveness involves assessing whether the guest is conscious and able to communicate. If the guest is unresponsive or in distress, the lifeguard should initiate appropriate first aid measures, including calling for emergency assistance if necessary.

This action prioritizes the safety and well-being of the guest, ensuring that any potential medical issues can be addressed swiftly. It reflects the lifeguard's training to act promptly and effectively in emergency situations, promoting a quick response that could be vital for the guest's health. Being attentive and ready to assist further ensures that the rescuer can provide the necessary care according to the guest's needs.

Other options, such as leaving the guest alone, immediately informing the lifeguard supervisor, or asking other guests for help, do not adequately address the critical needs of the rescued individual. Each of those actions may delay necessary care or create additional hazards, making them less appropriate in this situation.
