To assess a client's pupillary reaction to accommodation, which action should the nurse take?

A. Note the speed of pupil constriction when a penlight is shined into the eye. This assesses the direct response to light, not accommodation. B. Determine if dilation of the pupils occurs when the room is darkened. This assesses the pupil's response to darkness, not accommodation. C. Compare the shape of each of the pupils bilaterally with normal room light. This assesses the shape and symmetry of pupils, not their reaction to accommodation. D. Observe pupil size when focusing on a near object and then a far object. This is the correct method to assess accommodation. The pupils should constrict when focusing on a near object and dilate when focusing on a far object.
