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

Choice A Reason: Observing pupil size when focusing on a near object and then a far object is correct. This choice is correct because it directly assesses the pupillary reaction to accommodation, which refers to the changes in pupil size that occur when the eyes shift focus between near and far objects. Observing the pupils while the client focuses on a near object and then a far object allows the nurse to assess how the pupils constrict (become smaller) or dilate (become larger) in response to changes in focus, providing valuable information about the client's accommodation reflex. Choice B Reason: Comparing the shape of each of the pupils bilaterally with normal room light is incorrect. While comparing the shape of each pupil bilaterally with normal room light is a valid assessment technique for evaluating pupillary size and symmetry, it does not specifically assess the pupillary reaction to accommodation. Therefore, this choice is not as directly relevant to assessing accommodation reflex as choice A. Choice C Reason: Noting the speed of pupil constriction when a penlight is shined into the eye is incorrect. This choice refers to assessing the pupillary light reflex, which involves observing the speed and extent of pupil constriction in response to a bright light stimulus. While this assessment is important for evaluating the pupillary response to light, it does not specifically assess accommodation, which involves changes in pupil size in response to changes in focus between near and far objects. Therefore, this choice is not directly relevant to assessing accommodation reflex. Choice D Reason: Determining if dilation of the pupils occurs when the room is darkened is incorrect. This choice involves assessing the pupillary response to changes in ambient light levels, which is known as the pupillary light reflex. While assessing pupil dilation in response to darkness is important for evaluating the pupillary response to changes in light, it does not specifically assess accommodation reflex. Therefore, this choice is not directly relevant to assessing accommodation reflex.
