What are the common signs of an unconscious diver?

The correct choice highlights the key indicators of an unconscious diver, which are a limp body and unresponsiveness. When a diver is unconscious, they typically cannot respond to external stimuli, indicating a loss of awareness and motor function. The body may go limp due to muscle relaxation and lack of control, which are critical signs for other divers or responders to recognize immediately.

These signs are essential for initiating the appropriate rescue protocol. It is crucial to first assess responsiveness to determine the condition of the diver quickly. A limp body suggests that the diver has lost muscle control, which can happen in cases of drowning or other emergencies. Recognizing this condition allows for prompt action, such as retrieving the diver from the water and beginning emergency resuscitation if necessary. Understanding these signs is vital for ensuring the safety and well-being of divers.
