Answer 1

When conducting visual acuity testing for a school-age child using a Snellen letter chart, the nurse should stand 20 feet away from the chart. The child should correctly identify three symbols on each line to pass the line, and should keep their glasses on throughout the testing.

Step-by-step explanation:

When conducting visual acuity testing for a school-age child using a Snellen letter chart, the nurse should stand 20 feet away from the chart. The Snellen chart presents Roman letters in lines of decreasing size, and the nurse should ensure that the child can correctly identify three symbols on each line to pass the line. Additionally, the child should keep their glasses on throughout the testing to accurately assess their visual acuity.
