Which of the following is a risk factor for airway obstruction related to aspiration risk?

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

Answer: (D)

Airway obstruction from aspiration happens when material enters the airway and protective swallowing or cough reflexes fail to clear it. The best indicator of this vulnerability is the label that identifies someone as being at risk for aspiration. Saying there is a risk for aspiration means the patient already has factors that predispose them to aspirate, so they are the primary predisposing state for an airway obstruction due to aspiration.

Dehydration isn’t a direct, primary predisposing factor for aspiration, though it can affect secretions. Being unable to cough or unable to communicate show impaired airway protection or inability to report symptoms, but they describe consequences or present signs rather than the underlying risk state. Thus, the statement that someone is at risk for aspiration best captures the predisposing condition for potential airway obstruction.
