Which of the following are true regarding NPA use?

• A. Lubricate before insertion
• B. Insert at 45-degree angle
• C. Inflate the cuff before insertion
• D. Use on any patient regardless of obstruction

Answer: (A)

Lubricating the nasopharyngeal airway before insertion reduces friction, makes the device glide in smoothly, and minimizes mucosal trauma and bleeding. This simple step directly improves success on the first attempt and patient comfort. As you insert, keep the airway along the floor of the nasal cavity and advance gently; use the bevel toward the nasal septum to reduce mucosal irritation. If you meet resistance, don’t force it—reposition, possibly lubricate again, or reassess nasal patency.

The other statements aren’t correct because a cuff is not inflated on an NPA, so inflating the cuff isn’t part of its use. It isn’t inserted at a 45-degree angle; the device is kept parallel to the palate and advanced along the nasal floor. And you don’t use an NPA in every patient regardless of obstruction—contraindications like suspected basal skull fracture or significant nasal/facial trauma or obstruction must be considered.
