Which factor best represents a risk for airway obstruction due to inability to clear secretions?

• A. Dehydration
• B. Unable to Cough
• C. Risk for Aspiration
• D. Unable to Communicate

Answer: (B)

Effective airway clearance relies on a strong cough that can expel mucus from the trachea and bronchi. When someone cannot cough, secretions accumulate and can block the airway, leading to obstruction and impaired ventilation. This direct link between the inability to generate an effective expulsive flow and airway blockage makes inability to cough the best indicator of risk for obstruction from secretions. Dehydration can make mucus thicker and harder to clear, which worsens clearance but doesn’t by itself prove an inability to clear secretions. Risk for aspiration describes secretions entering the airway, which is important, but it’s not the same as the person’s failure to clear secretions once they’re there. Inability to communicate affects reporting and detection but not the mechanical process of clearing secretions.
