The nurse tells a patient that he will be performing a visual acuity test using the Snellen eye chart. The patient asks how the test is done. The nurse's best reply is:

"You stand 20 feet away from the chart while I test each of your eyes."

The number beside the largest print read is your visual acuity score!

"I will be testing your vision with your reading glasses on."

"You stand 50 feet away from the chart while I test each of your eyes."

Answer and Explanation

The Correct Answer is A

A.   The patient should stand 20 feet away from the Snellen chart to accurately measure visual acuity, which is the standard procedure.

B.   The number beside the largest print is not the correct visual acuity score; the patient must read progressively smaller lines.
C.   Testing with reading glasses is appropriate only for patients who need them for close-up vision, but the Snellen test typically measures distance vision.
D.   The distance should be 20 feet, not 50 feet, to ensure proper testing conditions.
