Which statement correctly distinguishes when to use an OPA versus an NPA?

• A. OPA is used for unconscious casualty with no gag reflex
• B. OPA for conscious casualty with gag reflex
• C. NPA for all unconscious casualties
• D. Use an OPA for an unconscious casualty with no gag reflex; use an NPA for a conscious or semi-conscious casualty or when OPA cannot be used, avoiding skull/face trauma

Answer: (D)

This item tests how to choose between an oropharyngeal airway (OPA) and a nasopharyngeal airway (NPA) based on the casualty’s level of consciousness and potential facial or skull injuries. An OPA helps keep the airway open by preventing the tongue from blocking the airway, but it can trigger the gag reflex. So it’s appropriate only when the person is unconscious and does not have an intact gag reflex, reducing the risk of gagging or vomiting. An NPA passes through the nose and tends to be better tolerated in patients who are conscious or semi-conscious, or when an OPA cannot be safely used—such as if there is gagging, nasal trauma, or suspected skull/facial injury. That combination of guidelines is why the correct approach is to use an OPA for an unconscious casualty with no gag reflex, and an NPA for a conscious or semi-conscious casualty or when the OPA cannot be used, with attention to avoiding skull or facial trauma.
