Chapter 41 Questions
Question 1 of 5
The nurse is caring for a client with increased fluid accumulation in the eye. When assessing the client, which structure within the eye is noted to drain fluid from the anterior chamber?
Correct Answer: C
Rationale: The canal of Schlemm drains the anterior chamber of the eye. By draining the fluid, it decreases the fluid amount and pressure in the eye. The other options have no draining ability.
Question 2 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.
Question 3 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 4 of 5
A client has been referred to an ophthalmologist for suspected macular degeneration. The nurse knows to prepare what test for the physician to give the client?
Correct Answer: C
Rationale: Clients with macular problems are tested with an Amsler grid. It is made up of a geometric grid of identical squares with a central fixation point. The examiner instructs the client to stare at the central fixation spot on the grid and report if they see any distortion of the squares. Clients with macular problems may say some of the squares are faded or wavy. An Ishihara polychromatic plate, visual field, or slit lamp test will not diagnose macular degeneration.
Question 5 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.
