Question 1 of 5
The nurse is assisting in providing coordination of services between the physician's office and vision specialist's office for a client who is being referred for potential retinal surgery. Which eye care specialist will the nurse make the referral to?
Correct Answer: C
Rationale: The ophthalmologist is a physician who performs surgery on clients with eye disorders. The optician makes eyeglasses or contact lenses. The optometrist tests vision and prescribes corrective lenses. The ophthalmic technician assists in selective eye tests and procedures.
Question 2 of 5
The nurse is obtaining a history on a client stating the inability to read the newspaper and seeing detail when looking at an image. Which assessment test would add additional data for a diagnosis?
Correct Answer: C
Rationale: The client states symptoms of the inability to discriminate letters, words, and details of an image, indicating the degeneration of the macula. If the macula is damaged, the client will only have the ability to see movement and gross objects in the peripheral fields. Assessing the peripheral vision will add essential information. The other visual tests are not as important at this time.
Question 3 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 4 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 5 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.
