Which statement best describes the use of an oropharyngeal airway (OPA) and a nasopharyngeal airway (NPA) regarding reflex suppression and usage?

• A. OPA is used in unresponsive patients without gag reflex; NPA can be used in some patients with a gag reflex and with limited mouth opening
• B. OPA is a nasal airway
• C. NPA cannot be used with gag reflex
• D. OPA is used only in pediatric patients

Answer: (A)

The key idea is choosing an airway device based on the patient’s level of consciousness and gag reflex, along with practical access to the airway. An oropharyngeal airway is designed to keep the airway open by preventing the tongue from occluding it, and it works best in patients who are unresponsive and do not have a gag reflex. If a person has any gag reflex, inserting an OPA can trigger coughing or vomiting and may worsen airway protection, so it’s avoided in those cases. A nasopharyngeal airway, on the other hand, goes through the nose and can be tolerated even if a patient has a gag reflex. It’s particularly helpful when there is limited mouth opening or when an oral airway isn’t feasible for other reasons. Because it bypasses the tongue and can be placed without provoking the same gag response, it’s suitable in some patients who still have protective reflexes. So, the best-fit statement reflects using an OPA in unresponsive patients without a gag reflex, and using an NPA in patients with a gag reflex (or when mouth opening is limited), with the appropriate nasal route considerations in mind.
