Answer 1

Visual acuity testing using a Snellen letter chart is a common method used by school nurses to check a student's vision. The chart consists of standard Roman letters in various sizes, with the acuity of vision determined by the ability to read the smallest letters at a specific distance. The test provides a rough estimate of vision quality and can help identify potential problems.

Step-by-step explanation:

Visual acuity testing using a Snellen letter chart is a common method used by school nurses to check a student's vision. The Snellen chart consists of standard Roman letters in various sizes. The acuity of a person's vision is determined by their ability to see the smallest letters on the chart at a specific distance. For example, someone with 20/60 vision can see the smallest letters at 20 feet that a person with normal vision can see from 60 feet away.

The nurse asks the student to read the letters on the chart from a certain distance to assess their visual acuity. The test provides a rough estimate of the student's vision quality and helps identify potential vision problems. If further evaluation is necessary, the nurse may conduct tests to assess the extent of the student's visual field and inspect the optic disk using an ophthalmoscope.
