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?

The right pupil constricts and the left consensually responds.

Both pupils are equal in size and constrict readily to the light source.

Bilateral pupil size changes as the distance of the light source varies.

The left iris is "notched" and the pupil size changes minimally.
