Answer to Question 1

Ans: B, C
The nurse should observe the older adult's usual pattern of activities. These observations are best made in the person's usual environment and address the person's ability to carry out activities. Older adults who report difficulty driving at night may have cataracts or other visual impairments.

Answer to Question 2

Ans: A, C
Nurses informally assess vision by asking the older adult to read printed material with various type sizes and describing details of a scene at a distance. A standard confrontation test is a gross measurement of peripheral vision fields. With standard vision tests, each eye is tested separately, and one should avoid using the hand as a cover.
