Which statement describes when a nasopharyngeal airway is appropriate?

• A. Awake or semi-conscious patient with intact gag reflex
• B. Unconscious patient with gag reflex
• C. Patient with significant nasal trauma
• D. Child with significant facial trauma

Answer: (A)

The key idea is that a nasopharyngeal airway is used to keep the airway open while letting the patient retain some protective reflexes and tolerate a nasal route. It sits through the nose into the back of the throat, helping prevent the tongue from occluding the airway without forcing a gag reflex to be completely suppressed as with an oropharyngeal airway. In a patient who is awake or semi-conscious and has an intact gag reflex, placing an NPA can maintain ventilation and oxygenation while the patient can still protect their airway if needed. This is why the statement describing an awake or semi-conscious patient with an intact gag reflex is most appropriate. The other scenarios are less suitable. An unconscious patient with a gag reflex is not typical—unconscious people often have a diminished gag reflex, and NPAs are usually used when reflexes are reduced or absent, not when a strong gag is present. Nasal trauma makes placement unsafe and risks further injury, and significant facial trauma can complicate or preclude safe insertion of a nasal airway.
