If the rescuing lifeguard has used a head splint to stabilize a subject with a suspected spinal injury, what should the assisting responder do after placing the backboard under the subject?

When a rescuing lifeguard uses a head splint to stabilize a subject with a suspected spinal injury, it indicates that the situation is critical and requires careful handling. After placing the backboard under the subject, it is essential for the assisting responder to remain on deck and take over stabilization. This approach helps ensure that the subject's head and neck remain secure and correctly aligned, reducing the risk of exacerbating a potential spinal injury.

By staying on the deck, the assisting responder can monitor the subject from above, ensuring that they remain stable and that the lifeguard can focus on other necessary rescue procedures. This division of responsibilities allows for a more effective rescue operation. The key here is to maintain spinal alignment and minimize movement, which is crucial for any suspected spinal injury scenario.

While checking the subject’s pulse, calling for additional help, or immediately entering the water could be important aspects of a rescue, stabilizing the subject effectively takes precedence when a spinal injury is suspected.
