Which statement best describes the use of an oropharyngeal airway (OPA)?

• A. OPA is used in unresponsive patients without gag reflex
• B. OPA is used only in conscious patients with gag reflex
• C. OPA cannot maintain airway secretions
• D. OPA is a nasopharyngeal device

Answer: (C)

The main idea is that an oropharyngeal airway is used to keep the airway open by preventing the tongue from blocking the pharynx in patients who are unconscious and do not have a gag reflex. It’s not designed to manage secretions; it simply holds the airway open, so suction is still needed to clear any secretions or fluid. It is also not a nasopharyngeal device—it's inserted through the mouth, and it’s typically avoided in patients with a gag reflex or in conscious patients because it can induce gagging or vomiting. Because of these limitations, the statement that best describes its use is that it cannot maintain airway secretions. The other points contradict how OPAs are used (they’re for unresponsive patients without gag reflex, not for conscious patients with gag reflex, and they’re not placed through the nose).
