Following an ophthalmologic exam, an anxious client asks the nurse, 'How serious is a refraction error?' Which is the best response from the nurse?
- A. It is nothing serious.
- B. It means corrective lenses are required.
- C. Simple surgery can fix this problem.
- D. This is normal for anyone your age.
Correct Answer: B
Rationale: Refractive errors can be corrected with glasses or contact lenses. Telling a client that 'nothing is serious' does not provide the necessary information to help alleviate fears. The word surgery can increase fears. If the refractive error is associated with aging, this is a normal finding but does not provide information about the condition.

A nurse is caring for a client who has undergone enucleation. What complication of enucleation should be addressed by the nurse?
- A. Hypotension
- B. Nausea and vomiting
- C. Hemorrhage
- D. Pneumonia
Correct Answer: C
Rationale: The nurse should take measures to prevent hemorrhage, a complication of enucleation, by applying a pressure dressing. Nausea and vomiting are common side effects of surgery. Enucleation does not increase risk of developing hypotension or pneumonia.
A client is diagnosed with blepharitis. What symptoms should a nurse monitor in this client?
- A. Patchy flakes clinging to the eyelashes
- B. A red pustule in the internal tissue of the eyelid
- C. Redness surrounding the conjunctival sac
- D. A halo around the pupil
Correct Answer: A
Rationale: Blepharitis is an inflammation of the lid margins. The nurse monitors visible patchy flakes clinging to the eyelashes and about the lids. The condition does not cause redness or a halo around the pupil. In case of a sty, the nurse would observe a red pustule in the internal tissue of the eyelid.
A nurse is caring for a client immediately following cataract removal. Which symptom would be most alarming to the nurse?
- A. Irritation in the operative eye
- B. Dilation of the pupil
- C. Dry, tickling cough
- D. Fever
Correct Answer: C
Rationale: Coughing can rise the intraocular pressure and should be avoided. A cough suppressant can be prescribed. The pupil was intentionally dilated during the surgical approach and will resolve. The client may complain of mild eye irritation in the immediate postoperative period. Fever can be a complication of cataract surgery but not expected in the immediate period postoperatively.
A client with chronic open-angle glaucoma is now presenting with eye pain and intraocular pressure of 50 mm Hg. An immediate iridotomy is scheduled. Which explanation by the nurse describes the desired effects of this procedure?
- A. Reverse optic nerve damage
- B. Restore vision
- C. Improve outflow drainage
- D. To relieve pain
Correct Answer: C
Rationale: Laser iridotomy or standard iridotomy is a surgical procedure that provides additional outlet drainage of aqueous humor. This is done to lower the IOP as quickly as possible since permanent vision loss can occur in 1 to 2 days. Once optic nerve damage occurs, it cannot be reversed, and vision is not restored. Pain that occurs with rising IOP will be controlled once pressure is lowered through improved outflow drainage.
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.
