Final answer:
When rescuing someone with a potential head, neck, or spinal injury in water, keep their face out of the water, stabilize the head and neck with a backboard and head immobilizer if available, and approach from behind to minimize further injury.
Step-by-step explanation:
When providing care to a person in the water with a suspected head, neck, or spinal injury, it is essential to keep the person's face out of the water to ensure they can breathe. If available, you should use a backboard with a head immobilizer to prevent movement of the spine, which could lead to further injury.
When approaching the injured person, do so from behind to minimize the risk of causing additional harm. It is critical not to rush the rescue in ways that jeopardize spinal safety, such as getting the person out of the water in less than one minute without proper support, which could worsen the injury. Instead, focus on stabilizing the person's head and neck until emergency services arrive.
Moreover, keep in mind other relevant first aid procedures, such as the FAST mnemonic for stroke victims, the proper method to assist a choking infant or adult, and the importance of not moving a person if a back or neck injury is suspected.
