Final answer:
The NPA can be used in patients with or without a gag reflex and requires lubrication with a water-based lubricant before insertion.
Step-by-step explanation:
The use of the NPA, or nasopharyngeal airway, has several important considerations. First, it can be used in patients with or without a gag reflex as it does not stimulate the gag reflex like an oral airway. Second, it does not allow the EMT to spend less time monitoring the patient's airway, but rather serves as a tool to maintain a clear and open airway. Third, proper lubrication with a water-based lubricant is important before inserting the NPA to ensure a smooth and comfortable insertion.
