- A. Pilocarpine

A patient has lost most of her vision as a result of macular degeneration. When attempting to meet this patients psychosocial needs, what nursing action is most appropriate?
- A. Encourage the patient to focus on her use of her other senses.
- B. Assess and promote the patients coping skills during interactions with the patient.
- C. Emphasize that her lifestyle will be unchanged once she adapts to her vision loss.
- D. Promote the patients hope for recovery.
Correct Answer: B
Rationale: Promoting coping skills supports psychosocial adjustment to vision loss from macular degeneration. Focusing on other senses or promising unchanged lifestyle may minimize the loss, and recovery is unlikely.
The nurse is administering eye drops to a patient with glaucoma. After instilling the patients first medication, how long should the nurse wait before instilling the patients second medication into the same eye?
- A. 30 seconds
- B. 1 minute
- C. 3 minutes
- D. 5 minutes
Correct Answer: D
Rationale: A 5-minute wait ensures adequate absorption of the first eye drop before administering the second, preventing dilution or reduced efficacy.
An older adult patient has been diagnosed with macular degeneration and the nurse is assessing him for changes in visual acuity since his last clinic visit. When assessing the patient for recent changes in visual acuity, the patient states that he sees the lines on an Amsler grid as being distorted. What is the nurses most appropriate response?
- A. Ask if the patient has been using OTC vasoconstrictors.
- B. Instruct the patient to repeat the test at different times of the day when at home.
- C. Arrange for the patient to visit his ophthalmologist.
- D. Encourage the patient to adhere to his prescribed drug regimen.
Correct Answer: C
Rationale: Amsler grid distortions in macular degeneration warrant immediate ophthalmologic evaluation. Vasoconstrictors, repeating tests, or drug adherence are not appropriate responses.
The nurse is teaching a patient to care for her new ocular prosthesis. What should the nurse emphasize during the patients health education?
- A. The need to limit exposure to bright light
- B. The need to maintain a low Fowlers position when removing the prosthesis
- C. The need to perform thorough hand hygiene before handling the prosthesis
- D. The need to apply antiviral ointment to the prosthesis daily
Correct Answer: C
Rationale: Hand hygiene prevents infection when handling an ocular prosthesis. Bright light, low Fowlers position, and antiviral ointment are not relevant to prosthesis care.
When administering a patients eye drops, the nurse recognizes the need to prevent absorption by the nasolacrimal duct. How can the nurse best achieve this goal?
- A. Ensure that the patient is well hydrated at all times.
- B. Encourage self-administration of eye drops.
- C. Occlude the puncta after applying the medication.
- D. Position the patient supine before administering eye drops.
Correct Answer: C
Rationale: Occluding the puncta prevents nasolacrimal duct absorption, reducing systemic side effects. Hydration, self-administration, and supine positioning do not address this issue.
