A nurse observes a patient whose right eye is fixed and dilated, for which cranial nerve (CN) would the nurse suspect nerve compression?

CNV

CN VIII

CN IV

CN III

Answer and Explanation

The Correct Answer is D

A.   CN V (Trigeminal nerve) is responsible for sensation in the face and motor function for chewing, not eye movement or pupil constriction.
B.   CN VIII (Vestibulocochlear nerve) deals with hearing and balance, not eye function.
C.   CN IV (Trochlear nerve) controls eye movement, but it does not typically affect the pupil in this way.
D.   Cranial nerve III (Oculomotor nerve) controls most eye movements and pupil constriction. A fixed and dilated pupil typically indicates damage to CN III, which may be due to nerve compression, often from increased intracranial pressure or herniation.
