New York State Basic Emergency Medical Technician (EMT-B) Practice Exam

Which of the following statements regarding nasopharyngeal airways is true?

1. NPA's should be coated with water-soluble lubricant prior to insertion

2. NPA's should be inserted without lubrication

3. NPA's can be used on all types of patients indiscriminately

4. NPA's are ineffective for unconscious patients

The correct answer is: NPA's should be coated with water-soluble lubricant prior to insertion

Using a water-soluble lubricant on nasopharyngeal airways (NPAs) before insertion is a best practice to facilitate a smoother and more comfortable insertion. The lubricant reduces friction, making it easier to navigate the airway while minimizing trauma to the nasal mucosa. This is especially important in emergency situations where patients may be anxious or combative. Proper lubrication helps ensure that the airway can be secured effectively without causing additional distress or injury to the patient. In contrast, inserting NPAs without lubrication could lead to discomfort or complications, particularly in patients with delicate nasal passages or those who may have sustained injuries. It is also not advisable to use NPAs indiscriminately for all patients; there are specific contraindications, such as significant facial trauma or a suspected skull base fracture, which necessitate careful consideration before use. Additionally, while NPAs can be used effectively in many cases, they can still provide challenges with unconscious patients who have a diminished gag reflex, requiring additional precautions in their use to avoid complications like airway obstruction or aspiration.
