- A. 30 seconds

The nurse has taken shift report on her patients and has been told that one patient has an ocular condition that has primarily affected the rods in his eyes. Considering this information, what should the nurse do while caring for the patient?
- A. Ensure adequate lighting in the patients room.
- B. Provide a dimly lit room to aid vision by limiting contrast.
- C. Carefully point out color differences for the patient.
- D. Carefully point out fine details for the patient.
Correct Answer: A
Rationale: Rods are responsible for low-light vision, so adequate lighting compensates for rod impairment. Dim lighting worsens vision, and rods do not affect color or fine detail perception.

- C. Encourage the patient to explore surgical corrections for the vision problem.

The nurse is providing health education to a patient newly diagnosed with glaucoma. The nurse teaches the patient that this disease has a familial tendency. The nurse should encourage the patients immediate family members to undergo clinical examinations how often?
- A. At least monthly
- B. At least once every 2 years
- C. At least once every 5 years
