Question 1 of 5
A nurse reviewing a client's record notes that the result of the client's latest Snellen chart vision test was 20/80. The nurse interprets the client's results in which way?
Correct Answer: D
Rationale: When interpreting visual acuity testing results using the Snellen chart, the recorded numeric fraction represents the distance the client is standing from the chart and the distance a normal eye could read that particular line. A reading of 20/80 means that the client can read at 20 feet what a client with normal vision can read at 80 feet. This indicates visual impairment but does not meet the criteria for legal blindness, which is defined as best-corrected vision in the better eye of 20/200 or worse. Normal visual acuity is 20/20.
Therefore, the correct interpretation is that the client can read at a distance of 80 feet what a client with normal vision can read at 20 feet.
Choice A is incorrect because 20/80 does not meet the criteria for legal blindness.
Choice B is incorrect as the client's vision is impaired.
Choice C is incorrect because it reverses the interpretation of the fraction.
