Physiological AdaptationQuestion 1653 of 2368
Why can an unconscious client lying supine develop an obstructed airway?
- The tongue moves backward and blocks the airway
- The epiglottis stays open and fills with mucus
- The uvula moves upward and closes the nasopharynx
- The trachea shifts toward the esophagus
Show answer
Correct answer: The tongue moves backward and blocks the airway
In the supine position the tongue often falls backward and blocks the airway, so the airway must be opened.
