Correct Answer is B

Explanation

B. Sucralfate should be taken on an empty stomach, at least 1 hour before meals or 2 hours after meals, to maximize its effectiveness. Food can interfere with its ability to coat the stomach lining.

A. Constipation is a common side effect of sucralfate, but it does not typically require discontinuation of the medication. Instead, clients are often advised to manage constipation with dietary fiber, fluids, and sometimes mild laxatives if necessary.

C. Antacids can interfere with sucralfate by altering its pH-dependent activation and should not be taken simultaneously. If antacids are necessary for symptom relief, they should be taken at least 30 minutes before or after sucralfate.

D. There is no specific instruction to remain upright after taking sucralfate
