- A. Assess if the pupils are equal and reactive to light.
- B. Assess vision on the Snellen chart.
- C. Assess peripheral vision.
- D. Assess color vision.
Correct Answer: C
Rationale: The client states symptoms of the inability to discriminate letters, words, and details of an image, indicating the degeneration of the macula.

The other visual tests are not as important at this time.
