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.
