An older adult client is admitted with the diagnosis of retinal detachment and is scheduled for laser surgery and scleral buckling procedure. The nurse anticipates which symptom(s) to be exhibited in this client? Select all that apply.
- A. Flashing lights
- B. Cobwebs in vision field
- C. Complete loss of vision in both eyes
- D. Loss of central vision
- E. Eye pain
- F. Arcus senilis
Correct Answer: A,B
Rationale: Many clients with detached retina experience a sensation of a curtain or veil lowering over vision field, flashing of lights, floaters, cobwebs, or spots. Complete vision loss can occur in the affected eye. Loss of central vision, eye pain, and arcus senilis are not indicated in this disorder.

A middle-aged client reports increasing difficulty reading newspaper print. Which of the following nursing explanations best describes this type of refractive error?
- A. Client is nearsighted.
- B. Lens has become cloudy and thick.
- C. Loss of elasticity of the lens.
- D. Floaters in the eye increase with age.
Correct Answer: C
Rationale: Presbyopia is a result of poor accommodation due to a loss of elasticity of the ciliary muscles and lens. Nearsighted refers to myopia. Cloudiness of lens is also associated with the aging process and does interfere with vision as a result of cataract formation. Floaters in the eyes are more apparent with aging but appear as dark spots.
A nurse is assessing a client for a fracture to the bony orbit. What would the nurse document if the assessment for fracture was positive?
- A. There is excessive tearing.
- B. The client's vision is blurred.
- C. A rust ring is seen around the pupil.
- D. The client has diplopia.
Correct Answer: D
Rationale: If the bony orbit is fractured, the eyes may appear asymmetric, and the client has diplopia or double vision. Excessive tearing, presence of rust rings, or blurry vision do not indicate a fractured bony orbit.
While cleaning gutters, a client reports getting debris in the eyes. On inspection, the nurse notes no obvious foreign object. Which diagnostic evaluation technique would be most beneficial for this client?
- A. Administer fluorescein dye.
- B. Obtain an x-ray for orbital fractures.
- C. Assess intraocular movements.
- D. Assess with tonometer.
Correct Answer: A
Rationale: Fluorescein dye stains the eye and helps to identify minute foreign body or abrasions in the cornea. X-ray of the eye orbit would be done if a blow to the area preceded the visit. Assessment of intraocular movements (cranial nerves III, IV, and VI) would not be indicated. Tonometry is done for assessment of intraocular pressure and would not be indicated.
A nurse is doing preoperative and postoperative teaching with a client who is undergoing cataract surgery. What is an important teaching point the nurse should emphasize to the client?
- A. Prepare for possible feelings of depression.
- B. Expect increased urine output.
- C. Eat soft, easily chewed food until healing is complete.
- D. Anticipate development of a periorbital hematoma.
Correct Answer: C
Rationale: Advise clients who have had cataract surgery to eat soft, easily chewed foods until healing is complete to avoid tearing from excessive facial movements. Clients who undergo cataract surgery do not become depressed, have increased urine output, or develop a periorbital hematoma.
The client with chronic open-angle glaucoma is receiving timolol eye drops. Which evaluation finding would indicate to the nurse the treatment is working?
- A. Intraocular pressure 15 mm Hg
- B. Reduced peripheral vision
- C. Halos around lights
- D. Decrease in nausea and vomiting
Correct Answer: A
Rationale: Timolol is a beta-blocker that is used topically to decrease the flow rate of aqueous humor in the eye. As flow rate decreases, the intraocular pressure decreases. IOP of 12 to 21 mm Hg is within normal range. Reduced peripheral vision, halos around lights, and blurred vision are all symptoms of open-angle glaucoma. Nausea and vomiting are more likely to occur with acute angle-closure glaucoma.
