Question

"The clinic nurse is preparing to test the visual acuity of a client using a Snellen chart. Which of the following identifies the accurate procedure for this visual acuity test?

a. Both eyes are assessed together, followed by the assessment of the right and then the left eye.
b. The right eye is tested followed by the left eye, and then both eyes are tested.
c. The client is asked to stand at a distance of 40ft. from the chart and is asked to read the largest line on the chart.
d. The client is asked to stand at a distance of 40ft from the chart and to read the line than can be read 200 ft away by an individual with unimpaired vision."

Answer 1

The accurate procedure for testing visual acuity using a Snellen chart is to assess both eyes together, followed by the right and left eye individually. The client is asked to stand 20 feet away from the chart and read the letters from the largest line to the smallest line they can clearly see.

Step-by-step explanation:

The accurate procedure for testing visual acuity using a Snellen chart is as follows:

1. The client is asked to stand at a distance of 20 feet from the chart.
2. Both eyes are assessed together, followed by the assessment of the right and then the left eye.
3. The client is asked to read the letters on the chart, starting from the largest line and moving to smaller lines until they can no longer read the letters clearly.

This procedure allows the nurse to determine the client's visual acuity based on the smallest line of letters they can read at a distance of 20 feet.
