If a person is submerged face down in water without known trauma, what should you do?

When a person is submerged face down in water without known trauma, acting quickly to remove them from the water is crucial. The primary goal in this scenario is to prevent further injury and to restore breathing as soon as possible. Time is essential because being submerged can lead to drowning, which can cause irreversible damage or death within minutes.

By promptly removing the person from the water, you can initiate necessary life-saving measures such as performing rescue breaths or CPR if they are not breathing. In this situation, the presence of water complicates matters, and it is critical to prioritize the immediate extraction of the victim over spinal motion restriction, which may not be essential if no trauma is suspected.

The other options, while they may seem relevant in certain contexts, do not prioritize the immediate need for the victim's safety and well-being in a drowning scenario. Spinal motion restriction, for instance, is more applicable when there is a suspicion of a spinal injury, which is not the case here. Instead, the focus should be on getting the person out of the water and starting resuscitation as needed.
