Question

A clinic nurse notes that following several eye examinations the health care provider has documented a diagnosis of legal blindness in the client's chart. Which of the following would the nurse expect to note documented as the result of the Snellen chart test?

Option 1: 20/20 vision
Option 2: 20/40 vision
Option 3: 20/100 vision
Option 4: 20/200 vision

Answer 1

A diagnosis of legal blindness would typically coincide with a documented Snellen test result of 20/200 vision or worse, meaning the patient's visual acuity is significantly impaired compared to average.

Step-by-step explanation:

When a clinic nurse observes a diagnosis of legal blindness in the client's chart, it indicates that the patient has severely limited vision. The Snellen chart test is commonly used to determine visual acuity. If the healthcare provider documented a diagnosis of legal blindness, it is likely that the person was unable to see letters smaller than a certain size on the Snellen chart. Specifically, the nurse would expect to note that the person has 20/200 vision or worse, as that is the typical threshold for legal blindness in the United States. This means that what the average person can see from 200 feet away, the legally blind person would need to be as close as 20 feet to see.
