A nurse is providing teaching to a client who has a duodenal ulcer and is starting to take sucralfate.Which of the following instructions should the nurse include in the teaching?

Choice A rationaleSucralfate forms a protective barrier when taken on an empty stomach, 1 hour before or 2 hours after meals, increasing its efficacy. Taking it with meals interferes with its mechanism of action.Choice B rationaleSucralfate does not require dietary fiber adjustments. Fiber affects bowel regularity and has no direct impact on the efficacy or absorption of sucralfate in treating duodenal ulcers.Choice C rationaleAdministering antacids with sucralfate can interfere with its action. Antacids should be taken at least 30 minutes before or after sucralfate to avoid interactions affecting drug absorption and efficacy.Choice D rationaleIncreasing fluid intake helps prevent constipation, a common side effect of sucralfate. Adequate hydration supports gastrointestinal motility, promoting bowel regularity and minimizing discomfort for the client.
