What should a lifeguard do if they suspect a patron has a head, neck, or back injury?

In the scenario where a lifeguard suspects that a patron may have sustained a head, neck, or back injury, the most critical action is to minimize movement of the victim and call for emergency medical services. This approach is essential as any unnecessary movement can exacerbate the injury and potentially lead to severe consequences, such as paralysis or further damage to the spinal cord.

By minimizing movement, the lifeguard helps stabilize the victim's condition while waiting for trained medical professionals to arrive. This allows for proper assessment and treatment, mitigating the risk of further harm. Calling for emergency medical services ensures that appropriate help is on the way, ensuring the victim receives timely care.

Encouraging the victim to stand up and walk, moving them quickly for assessment, or ignoring the situation can all lead to additional risks or complications. These actions may inadvertently worsen an existing injury and compromise the person's well-being, which is why they are not appropriate responses in this critical situation.
