Which condition relates to decreased consciousness as a risk for airway obstruction?

• A. Dehydration
• B. Unable to Cough
• C. Patients with Decreased LOC
• D. Unable to Communicate

Answer: (C)

Airway protection depends on conscious control and reflexes like coughing and swallowing. When consciousness is decreased, these protective reflexes are blunted, so the airway can be easily obstructed by the tongue, loose tissues, or secretions, and the risk of aspiration rises. That’s why the group described as having decreased level of consciousness is the one most clearly related to airway obstruction risk. Dehydration doesn’t directly reflect impaired airway protection, being unable to cough is a sign of impaired airway clearance rather than the conscious state itself, and being unable to communicate doesn’t specify the level of consciousness or airway protection.
