The client with calcium renal calculi is prescribed cellulose sodium phosphate (Calcibind). The client asks the nurse, “How will this medication help prevent my stones from coming back?” Which statement is the nurse’s best response?

1. “Calcibind reduces the uric acid level in your bloodstream and the uric acid excreted in your urine.” 2. “This medication will decrease calcium levels in the bloodstream by increasing calcium excretion in the urine.” 3. “It binds calcium from food in the intestines, reducing the amount absorbed in the circulation.” 4. “The medication will help alkalinize the urine, which reduces the amount of cystine in the urine.”
