Question 1 of 5
A nurse is assessing a client's cranial nerves. What cranial nerve would be assessed when checking a client's gag reflex?
Correct Answer: A
Rationale: The correct answer is A: CN IX (Glossopharyngeal nerve). The gag reflex is mediated by the glossopharyngeal nerve (CN IX), which innervates the back of the throat and helps in swallowing. CN V (Trigeminal nerve) is responsible for sensations in the face and chewing, not the gag reflex. CN X (Vagus nerve) controls various functions like heart rate and digestion but is not directly involved in the gag reflex. CN XII (Hypoglossal nerve) controls tongue movement, not the gag reflex.
Therefore, A is the correct choice for assessing the gag reflex.
