Question 1 of 5
The nurse is caring for geriatric clients who state that they are prescribed reading glasses. Some individuals state needing assistance with seeing writing far away, and others need assistance with closer vision. What does the nurse understand to be related to visual changes caused by aging?
Correct Answer: D
Rationale: The changes that occur in vision during aging, which include difficulty reading and the need for reading glasses, include changes in accommodation. Accommodation occurs when the ciliary muscles contract or relax to focus an image on the retina.
Question 2 of 5
The nurse is establishing a visual test using the Snellen chart for a client experiencing visual changes. At which distance should the nurse instruct the client to stand?
Correct Answer: B
Rationale: The nurse is correct in instructing the client to stand at a 20-feet distance from the Snellen chart. Often, the nurse places tape on the floor to denote the correct distance for the client to stand.
Question 3 of 5
The nurse is completing a corneal light reflex test on a client, using a penlight. Which result would indicate a normal test result?
Correct Answer: D
Rationale: A normal corneal light reflex test is when the light reflex is even, reflecting the light at the same spot on both eyes. If the light reflex is uneven, it indicates deviated alignment of the eyes, possibly due to muscle weakness or paralysis.
Question 4 of 5
The nurse is assisting the eye surgeon in completing an examination of a client's eye. Which piece of equipment would the nurse provide to the surgeon to examine the optic disc under magnification?
Correct Answer: B
Rationale: The nurse is correct to provide an ophthalmoscope to the surgeon for examination of the optic disc. A retinoscope is used to determine errors in refraction. A tonometer measures intraocular pressure. An Amsler grid tests for problems with the macula.
Question 5 of 5
The nurse is evaluating the client taking the color vision test. Which response would the nurse anticipate when caring for a client with normal color vision?
Correct Answer: A
Rationale: The nurse is correct to anticipate the client being able to identify numbers and shapes dictated by different color codes. The other options do not test for color vision or indicate an inability to differentiate colors.
