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 rationale Sucralfate should not be taken with meals. Food can interfere with the medication's ability to bind to the ulcer base. It is a mucosal protectant that works by creating a protective barrier, which requires an acidic environment and an empty stomach to be most effective. It should be taken at least one hour before meals. Choice B rationale Reducing dietary fiber is not a recommended instruction for sucralfate. This medication can cause constipation as a common side effect because of its aluminum content. Increasing dietary fiber, along with fluid intake, is a strategy to prevent or manage this gastrointestinal side effect. Choice C rationale Administering an antacid with sucralfate is not recommended. Antacids can neutralize the stomach's acidic environment, which is necessary for sucralfate to be activated and form its protective polymer barrier. A client should wait at least 30 minutes before or after taking sucralfate to take an antacid. Choice D rationale Sucralfate often causes constipation due to its aluminum-sucrose complex. Increasing fluid intake helps to soften stools, facilitating easier bowel movements and mitigating this common side effect. This instruction is crucial for client comfort and adherence to the medication regimen.
