The nurse is testing a patient's visual accommodation. How is accommodation assessed?
A) Pupillary dilation when looking at a distant object
B) Involuntary blinking in the presence of bright light
C) Pupillary constriction when looking at a near object
D) Changes in peripheral vision in response to bright light
Visual Accommodation
The adjustment of the lens of the eye to focus on objects at varying distances.
Pupillary Constriction
The narrowing of the pupils, the central opening of the eyes, often in response to light exposure or during the process of focusing on near objects.
Peripheral Vision
The ability to see objects and movement outside of the direct line of vision.
- Explain the function of the autonomic nervous system in regulating eye activities, specifically focusing on pupillary reaction and accommodation mechanisms.

Final Answer :
C
Explanation :
The muscle fibers of the iris contract the pupil in bright light and accommodate for near vision, which also results in pupil constriction. The other responses are not correct.
