Describe the "cross-chest" rescue technique.

The "cross-chest" rescue technique is correctly described as a method used to save a victim by reaching across the body to pull them to safety without entering the water. This technique is particularly useful in situations where it might be unsafe or impractical for the lifeguard to enter the water, such as in shallow water or when the victim is close to the edge of a pool.

By crossing the arms over the chest, the rescuer can use their stronger upper body strength to grab the victim and pull them toward safety, minimizing the risk of injury to both the rescuer and the victim. This technique is an essential skill for lifeguards, as it helps ensure that they can assist distressed swimmers effectively while maintaining their own safety.

Other methods mentioned, such as diving into the water or pulling a victim by their legs, may not provide the same level of safety or control. It's important for rescuers to be trained in techniques that emphasize both the safety of the victim and themselves.
