Which is the proper technique the nurse should use to test for accommodation?
Explanation & Rationale
A. Shining a penlight assesses the pupillary light reflex, not accommodation. Parallel movement of the eyes does not evaluate the near-response mechanism. B. During accommodation, the pupils constrict, not dilate, when focusing on a near object. Pupil dilation would be abnormal in this context. C. The consensual light reflex occurs when shining light in one eye causes constriction in the opposite eye. This tests cranial nerves II (optic) and III (oculomotor) but does not assess accommodation. D. To test accommodation, the nurse asks the client to focus on a distant object and then shift focus to a near object, such as a pen moved slowly toward the bridge of the nose. The nurse observes for convergence (eyes moving inward) and pupil constriction. This properly evaluates the accommodation response.
