The nurse is assessing the function of the client's cranial nerve XII (hypoglossal). Which activity will allow the nurse to assess this nerve during the client's physical assessment?
1. "Can you stick out your tongue?"
2. "I'm going to ask you to taste something and tell me what you think it is."
3. "Close your eyes and tell me when you feel me touch your face with this wisp of cotton."
4. "I'm going to lightly touch the back of your throat with this tongue depressor."
Correct Answer: 1
An intact cranial nerve XII (hypoglossal) allows the client to stick out the tongue. An intact cranial nerve VII (facial) allows the client to taste. An intact cranial nerve V (trigeminal) allows the client to identify sensations on the face. Cranial nerve X (vagus) is responsible for producing the gag reflex when the back of the client's throat is lightly touched.
