The nurse is administering sucralfate to a client with stomatitis secondary to chemotherapy. The client wants to take the medication after breakfast. How should the nurse respond?

A. Document the client's refusal of the medication at this time: While documentation is necessary if a medication is refused, the priority is to educate the client first. The nurse should explain the proper timing of sucralfate to promote understanding and adherence rather than simply accepting refusal.B. Explain the need to take the medication at least 1 hour before meals: Sucralfate acts by forming a protective barrier over ulcerated mucosa and must be taken on an empty stomach for maximum effectiveness. Administering it one hour before meals ensures the stomach lining is properly coated before food intake.C. Allow the client to take the medication up to 1 hour after breakfast: Taking sucralfate after a meal diminishes its ability to bind effectively to the mucosa. Food interferes with its action, so post-meal dosing is inappropriate for achieving therapeutic benefit.D. Instruct the client to take it when the meal tray is delivered: Taking sucralfate at mealtime is too late for optimal therapeutic effect. At that point, gastric contents may interfere with its binding to ulcerated areas, reducing its protective action.
