While conducting a physical assessment, the nurse shines a pen light into a client's right eye and moves the light source to check the client's left eye. Which finding indicates the need for further evaluation?

A. Bilateral pupil size changes as the distance of the light source varies: This is a normal finding and reflects the pupil's reaction to light. B. The right pupil constricts and the left consensually responds: This is a normal finding, showing proper pupil response to light. C. The left iris is "notched" and the pupil size changes minimally: A notched iris and minimal pupil response can suggest a neurological issue and warrants further evaluation. D. Both pupils are equal in size and constrict readily to the light source: This is a normal finding, indicating proper function of the pupillary reflex.
