If Ms. Barrett’s distance vision is 20/30, which of the following statements is true?
A.
The client can read from 20' what a person with normal vision can read at 30'.
B.
The client can read from 30' what a person with normal vision can read at 20'.
C.
The client can read the entire chart from 30'.
D.
The client can read the chart from 20' with the left eye and from 30' with the right eye.
The Answer Is:
A
This question includes an explanation.
Explanation:
The numerator, which is always 20, is the distance in feet between the chart and the client. The denominator, which ranges from 10 to 200, indicates the distance at which a normal eye can read the chart. The eye chart the nurse uses is the Snellen chart, which assesses distance vision.Health Promotion and Maintenance
