A patient got a sliver of glass in his eye when a glass container at work fell and shattered. The glass had to be surgically removed and the patient is about to be discharged home. The patient asks the nurse for a topical anesthetic for the pain in his eye. What should the nurse respond?
- A. Overuse of these drops could soften your cornea and damage your eye.
- B. You could lose the peripheral vision in your eye if you used these drops too much.
- C. Im sorry, this medication is considered a controlled substance and patients cannot take it home.
- D. I know these drops will make your eye feel better, but I cant let you take them home.
Correct Answer: A
Rationale: Topical anesthetics can soften the cornea with overuse, risking permanent damage. They are not controlled substances, and peripheral vision loss is not a primary concern.

A 6-year-old child is brought to the pediatric clinic for the assessment of redness and discharge from the eye and is diagnosed with viral conjunctivitis. What is the most important information to discuss with the parents and child?
- A. Handwashing can prevent the spread of the disease to others.
- B. The importance of compliance with antibiotic therapy
- C. Signs and symptoms of complications, such as meningitis and septicemia

Rationale: Viral conjunctivitis is highly contagious, and handwashing prevents spread. Antibiotics are ineffective, meningitis is not a risk, and surgery is not indicated.
A patient with low vision has called the clinic and asked the nurse for help with acquiring some low-vision aids. What else can the nurse offer to help this patient manage his low vision?
- A. The patient uses OTC NSAIDs.
- B. The patient has a history of stroke.
- C. The patient has diabetes.
- D. The patient has Asian ancestry.
Correct Answer: C
Rationale: Diabetes is a risk factor for glaucoma, which can worsen low vision. The nurse can offer education on managing diabetes to protect vision. NSAIDs, stroke, and Asian ancestry are not directly relevant.
Several residents of a long-term care facility have developed signs and symptoms of viral conjunctivitis. What is the most appropriate action of the nurse who oversees care in the facility?
- A. Arrange for the administration of prophylactic antibiotics to unaffected residents.
- B. Instill normal saline into the eyes of affected residents two to three times daily.
- C. Swab the conjunctiva of unaffected residents for culture and sensitivity testing.
- D. Isolate affected residents from residents who have not developed conjunctivitis.
Correct Answer: D
Rationale: Isolating affected residents prevents the spread of viral conjunctivitis. Antibiotics, saline flushes, and swabbing unaffected residents are ineffective or unnecessary.
The nurses assessment of a patient with significant visual losses reveals that the patient cannot count fingers. How should the nurse proceed with assessment of the patients visual acuity?
- A. Assess the patients vision using a Snellen chart.
- B. Determine whether the patient is able to see the nurses hand motion.
- C. Perform a detailed examination of the patients external eye structures.
- D. Palpate the patients periocular regions.
Correct Answer: B
Rationale: If the patient cannot count fingers, testing hand motion detection is the next step to assess visual acuity. Snellen charts require better vision, and external exams or palpation do not measure acuity.
A patient with glaucoma has presented for a scheduled clinic visit and tells the nurse that she has begun taking an herbal remedy for her condition that was recommended by a work colleague. What instruction should the nurse provide to the patient?
- A. The patient should discuss this new remedy with her ophthalmologist promptly.
- B. The patient should monitor her IOP closely for the next several weeks.
- C. The patient should do further research on the herbal remedy.
- D. The patient should report any adverse effects to her pharmacist.
Correct Answer: A
Rationale: Herbal remedies may interact with glaucoma treatment, so prompt discussion with the ophthalmologist is essential. Self-monitoring IOP is not feasible, and research or pharmacist reporting is secondary.
