A client with peptic ulcer disease has been prescribed sucralfate. What health education should the nurse provide to this client?

A. Take the medication at bedtime to accommodate sedative effects: Sucralfate does not have sedative properties. It acts locally in the gastrointestinal tract by forming a protective barrier over ulcers, so timing is related to food and drug interactions, not sleep. B. Ensure adequate potassium intake during therapy: Sucralfate does not cause potassium depletion and does not interfere with potassium balance. There is no need for specific potassium intake adjustments during therapy with this medication. C. Blood levels will be evaluated after 1 week: Sucralfate is not absorbed systemically to a significant extent, so blood level monitoring is not required. Its effects are localized to the gastric mucosa, making serum concentration irrelevant. D. Take the medication 2 hours before or after other medications: Sucralfate can interfere with the absorption of many drugs by forming a coating in the GI tract. To prevent reduced efficacy of other medications, it should be spaced at least 2 hours apart from them.
