What is a sign that an unconscious casualty may have a blocked airway?

1. The casualty is breathing normally

2. The casualty can cough

3. The tongue may relax and block the airway

4. The casualty can follow commands

The correct answer is: The tongue may relax and block the airway

A sign that an unconscious casualty may have a blocked airway is that the tongue may relax and obstruct the airway. In an unconscious state, the muscles in the body, including those that control the tongue, relax. This relaxation can cause the tongue to fall back into the throat, potentially blocking the passage of air and interfering with normal breathing. Identifying this sign is crucial because a blocked airway can lead to serious consequences if not addressed promptly. In contrast, if a casualty is breathing normally, can cough, or can follow commands, these indicators suggest that the airway is likely clear. Normal breathing means air is moving in and out of the lungs effectively, while a cough reflex indicates that the airway is still functional and the body can respond to potential obstructions. Following commands suggests a level of consciousness and responsiveness that typically indicates a patent airway. Therefore, the relaxation of the tongue in an unconscious person is a critical indicator of a potential airway blockage.
