Answer to Question 1

ANS: A
When the Snellen chart is used to check visual acuity, the patient should stand 20 feet away. Accommodation is tested by looking at an object at both near and far distances. Shining a pen light into the eyes tests for pupil response. Following the examiner's fingers with the eyes tests extraocular movements.

Answer to Question 2

ANS: D
The decrease in peripheral vision may indicate glaucoma, which is not a normal visual change associated with aging and requires rapid treatment. The other patient statements indicate visual problems (presbyopia, dryness, and lens opacity) that are considered a normal part of aging.
