Which airway cannot be used in a conscious patient due to gag reflex?

• A. Endotracheal tube
• B. Oropharyngeal airway
• C. Nasal airway
• D. Laryngeal mask

Answer: (B)

The gag reflex limits insertion of devices that irritate the oropharynx. An oropharyngeal airway sits in the back of the mouth and can provoke the gag reflex in a conscious patient, making insertion uncomfortable and dangerous due to risk of vomiting and aspiration. Because the gag reflex is intact in awake patients, this airway is not used when someone is conscious. Other devices are typically used only after airway reflexes are suppressed (as with anesthesia or deep sedation), or can be tolerated in awake patients under appropriate conditions, such as a nasal airway in a cooperative patient.
