The nurse is testing a patient's visual accommodation, which refers to which action?
Pupillary dilation when looking at a far object
Pupillary constriction when looking at a near object
Changes in peripheral vision in response to light
Involuntary blinking in the presence of bright light
The Correct Answer is B
A. Pupillary dilation when looking at a far object: While dilation occurs with distance, the question specifically refers to near vision.
B. Pupillary constriction when looking at a near object: Accommodation is the process by which the eyes adjust to focus on near objects, which includes pupillary constriction and lens thickening.
C. Changes in peripheral vision: This describes visual field testing, not accommodation.
D. Involuntary blinking in bright light: This describes the corneal reflex, not accommodation.
