When an unconscious patient needs an airway adjunct, which device is preferred as a first-line option?

• A. Nasopharyngeal airway (NPA) as the first-line if gag reflex present.
• B. Oropharyngeal airway (OPA) if gag reflex is absent; if gag reflex is present, consider a nasopharyngeal airway (NPA).
• C. Endotracheal tube.
• D. Laryngeal mask airway.

Answer: (B)

Airway adjunct choice hinges on the gag reflex. In an unconscious patient, you want to secure the airway with the least risk of provoking a protective reflex while keeping the tongue from occluding the airway. If the gag reflex is absent, an oropharyngeal airway is used because it easily prevents the tongue from blocking the back of the throat and is quick to insert. If the gag reflex is present, it is safer to avoid stimulating it, so a nasopharyngeal airway is preferred since it sits above the gag zone and is generally better tolerated, helping to keep the airway open without triggering gagging. Endotracheal intubation is a definitive airway and is reserved for when a controlled, secured airway is needed beyond a basic adjunct, while a laryngeal mask airway is useful in certain settings but is not the first-line choice for an unconscious patient requiring a simple airway adjunct.
