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. The left iris is "notched" and the pupil size changes minimally. A notched iris may indicate trauma, surgical history, or congenital defects, while minimal pupil reaction suggests possible neurological impairment, optic nerve dysfunction, or iris damage. This finding requires further evaluation. B. Both pupils are equal in size and constrict readily to the light source. This is a normal pupillary response, indicating intact cranial nerve II (optic nerve) and cranial nerve III (oculomotor nerve) function. C. Bilateral pupil size changes as the distance of the light source varies. This describes pupillary accommodation, which is a normal reflex where pupils constrict when focusing on a near object and dilate when focusing on a distant object. D. The right pupil constricts and the left consensually responds. A consensual response means that when light is shined in one eye, the opposite eye constricts as well. This is a normal finding, indicating intact neurological function.
