What is NOT a normal finding in a cranial nerve exam?

In a cranial nerve exam, the assessment of facial function is crucial, as it involves examining the integrity and function of the facial nerve, which is responsible for controlling the muscles of facial expression. Facial paralysis is not considered a normal finding; in fact, it suggests dysfunction of the facial nerve, which can result from various conditions, including stroke, Bell's palsy, or other neurological disorders.

Conversely, intact visual fields, pupils that are equal, round, and reactive to light (PERRL), and facial symmetry are all indicators of normal cranial nerve function. An intact visual field shows that the optic nerve is functioning properly, while PERRL indicates that both the optic and oculomotor nerves are intact and functioning as they should. Symmetry in facial features suggests that the facial nerve is operating effectively and there are no signs of paralysis. Thus, the presence of facial paralysis denotes an abnormal finding in a cranial nerve exam, highlighting dysfunction rather than normalcy.
