When performing a head-to-toe assessment, during which part would the nurse evaluate cranial nerve (CN) IX, X, and XII?

Ears

Mouth and throat

Head and face

Mental status examination

Answer and Explanation

The Correct Answer is B

A. Ears: Evaluation of the ears is primarily concerned with hearing and balance, which involve cranial nerves such as VIII (Vestibulocochlear), not IX, X, and XII.

B. Mouth and throat: Cranial nerves IX (Glossopharyngeal), X (Vagus), and XII (Hypoglossal) are assessed through the examination of the mouth and throat. CN IX and X are evaluated by checking the gag reflex and the ability to swallow, while CN XII is assessed by examining tongue movements.

C. Head and face: The assessment of the head and face generally involves cranial nerves V (Trigeminal) and VII (Facial), which control facial sensation and movement, rather than IX, X, and XII.

D. Mental status examination: While mental status is crucial for overall health assessment, it does not specifically target cranial nerves IX, X, and XII.
