A nurse is caring for a client newly diagnosed with glaucoma. Which would be a priority in the nurse's teaching about maintaining normal pressure range in the eye?
- A. Increase fiber in the diet.
- B. Avoid reading.
- C. Eat small meals.
- D. Treat allergy symptoms promptly.
Correct Answer: A
Rationale: Adding fiber to the diet will increase ease of bowel movements and prevent constipation and straining, which can inadvertently increase intraocular pressure. Eating small meals is insignificant in maintaining intraocular pressure. Avoid over-the-counter treatment of cold and allergy symptoms if contains cholinergic blockers. Reading is not significant in changing intraocular pressure, but eye strain should be avoided.

The nurse is caring for a client with open-angle glaucoma. What does the nurse know that this disease causes? Select all that apply.
- A. Atrophy of nerve fibers in the central area of the retina
- B. Edema of the lens
- C. Degeneration of the optic nerve
- D. Edema of the cornea
- E. Atrophy of nerve fibers in the peripheral areas of the retina
Correct Answer: C,D,E
Rationale: Open-angle glaucoma occurs when structures in the drainage system (i.e., trabecular meshwork and canal of Schlemm) degenerate, and the exit channels for aqueous fluid become blocked. As the intraocular pressure (IOP) rises, it causes edema of the cornea, atrophy of nerve fibers in the peripheral areas of the retina, and degeneration of the optic nerve. This makes the other options incorrect.
An older adult client is scheduled for cataract surgery and asks the nurse, 'Will I need to wear thick lenses after surgery?' Which is an appropriate response from the nurse?
- A. An implanted lens has replaced the need for corrective glasses.
- B. Contact lenses are preferred by most clients after this surgery.
- C. They can make corrective lenses much thinner now.
- D. No lens is necessary with cataract surgery.
Correct Answer: A
Rationale: Vision is usually restored after cataract surgery with an intraocular lens implant. Contact lenses can be used but can be burdensome for older adults. Corrective glass lenses can cause a distortion of peripheral vision and only one lens is required (over operative eye). To restore vision after cataract surgery, a lens is required.
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 who has exhibited repeated return of hordeolum (sty). Which assessment finding is most important in determining care for this client?
- A. Dabbing the eyes multiple times with a washcloth
- B. Presence of low blood sugar
- C. Use of disposable wash cloths
- D. Use of antibacterial facial wash
Correct Answer: A
Rationale: Hordeolum is an infection usually caused by Staphylococcus aureus. To avoid transferring microorganisms, the client should not dab the eyes multiple times with a washcloth but should instead clean the unaffected eye first and change the washcloth, towel, and water after contact with the affected eye. The nurse should also instruct the client to use separate fresh tissues, cotton balls, or gauze for each wiping stroke when cleaning exudate from the eye. Clients with high blood sugar are more likely to develop hordeolum. Use of disposable wash cloths, antibacterial cleansers, and good hygiene practices are preventable techniques.
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.
