The nurse is planning to administer sucralfate to a client with peptic ulcer disease. Which action should the nurse include in this client's plan of care?

A. Assess for secondary Candida infection: Sucralfate acts locally in the stomach to form a protective barrier over ulcers; it does not suppress the immune system or significantly alter the microbial flora. Therefore, it does not increase the risk of Candida infections, making this assessment unnecessary specifically for sucralfate therapy. B. Monitor for electrolyte imbalance: Sucralfate does not typically cause major electrolyte disturbances. Unlike antacids, which may alter serum electrolytes, sucralfate's mechanism is physical coating of the gastric mucosa rather than altering gastric pH significantly or causing systemic absorption issues. C. Administer sucralfate once a day, preferably at bedtime: Sucralfate is usually prescribed multiple times a day, typically four times daily, before meals and at bedtime. Administering it only once daily would not provide adequate mucosal protection necessary for ulcer healing. D. Give sucralfate on an empty stomach: Sucralfate must be given on an empty stomach for optimal binding to the ulcer site. Food can interfere with its ability to adhere properly to the mucosal lining, reducing its effectiveness in promoting ulcer healing.
