Your patient is reporting a complete resolution of his symptoms 3 weeks after starting the H2 antagonist medication, cimetidine. His prescription is for 4 weeks of treatment, Which statement best reflects what the nurse's instructions should be?

A. “I’m glad to hear that. Keep the remaining medication in case your symptoms come back.” Stopping the medication early can prevent full healing and may lead to symptom recurrence or incomplete treatment of the underlying condition. Keeping leftover medication without completing the course is unsafe. B. “I’m glad to hear that. Continue with your medication until it is all done. We can set a follow-up appointment next month.” Completing the prescribed course ensures adequate healing of gastric or duodenal ulcers and reduces the risk of recurrence. Scheduling follow-up allows assessment of treatment effectiveness and monitoring for side effects. C. "I'm glad to hear that. Go ahead and discontinue the medication and schedule a follow-up for next month." Discontinuing the medication early, even if symptoms have resolved, can result in incomplete treatment and possible recurrence of ulcers or acid-related issues. Continuing the full course is necessary. D. "I'm glad to hear that. You should be clear to reintroduce all the food items we eliminated during your treatment." Dietary modifications are individualized. Abruptly reintroducing all restricted foods without guidance may trigger symptom recurrence. Education should include gradual reintroduction and monitoring tolerance.
