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?

A. "Take this medication with meals": Sucralfate should be taken on an empty stomach, usually 1 hour before meals or 2 hours after meals, to maximize its effectiveness in coating the ulcer. Taking it with meals may interfere with its protective effect. B. "Reduce dietary fiber while taking the medication": Sucralfate does not specifically require reducing dietary fiber. In fact, maintaining adequate fiber intake is important for overall digestive health. C. "Administer an antacid with the medication": Antacids should be avoided within 30 minutes before or after taking sucralfate. Antacids can reduce the medication's effectiveness by interfering with its ability to form the protective gel coating over the ulcer. D. "Increase fluid intake while taking the medication": Sucralfate can cause constipation as a side effect, and increasing fluid intake can help prevent or alleviate this. It also ensures proper hydration, which is important when taking any medication.
