A lifeguard should assess the injury and provide appropriate first aid for a minor injury to ensure the safety and well-being of the affected individual. By taking this action, the lifeguard demonstrates their training and responsibility. It is important to evaluate the injury to determine its severity and decide on the necessary treatment. This could involve cleaning a wound, applying a bandage, or providing ice for a sprain, depending on the nature of the injury.
Providing appropriate first aid helps prevent any potential complications, reduces the risk of infection, and can significantly improve the comfort of the injured individual. Addressing the injury promptly also maintains a safe environment for all patrons. While it's essential to monitor the overall environment, the lifeguard's duty includes responding to injuries to ensure that all swimmers are protected and cared for appropriately.
Ignoring the injury or only asking the swimmer to leave the water would not fulfill the lifeguard's responsibilities, as it could lead to further complications for the injured person. Calling for medical assistance may not be necessary for minor injuries unless they worsen or the injury is more serious than initially assessed.
