The nurse is providing discharge instructions to a patient with chronic kidney disease who is on hemodialysis and prescribed sevelamer carbonate. Which statement by the patient requires further intervention by the nurse?

A. "I will take this medication with food.": Sevelamer carbonate binds dietary phosphate in the gut, so taking it with meals optimizes phosphate control in patients with chronic kidney disease. This demonstrates correct understanding of the timing and purpose of the medication. B. "I will take this medication two to three hours after I have eaten meat.": Sevelamer carbonate should be taken with meals to bind dietary phosphate effectively. Delaying the dose after eating protein-rich foods like meat reduces its efficacy, increasing the risk of hyperphosphatemia. This statement indicates a misunderstanding that requires correction by the nurse. C. "I will wait three hours after taking this medication before taking other medications.": Sevelamer can bind other orally administered drugs and reduce their absorption. Waiting at least two to three hours between sevelamer and other medications is appropriate and demonstrates correct understanding of drug interactions. D. "I will drink fluids to prevent constipation": Sevelamer can cause constipation as a side effect. Maintaining adequate fluid intake is an appropriate measure to prevent constipation and demonstrates understanding of safe self-care while taking this medication.
