A patient who is on hemodialysis for chronic kidney disease is given sevelamer hydrochloride (Renagel) with meals. What explanation should be provided to the patient as the primary reason the medication is being given?
a. To prevent metabolic acidosis
b. To relieve gastric irritation from excess acid production
c. To prevent gastrointestinal ulcer formation
d. To prevent damage to bones from high phosphorus levels
ANS: D
Associated with a low calcium level is hyperphosphatemia, a phosphorous level above 5 mg/dL. These imbalances cause the bones to release calcium, causing patients to be prone to fractures. Sevelamer hydrochloride (Renagel) is the first-line ordered phosphate binder for those on dialysis. It must be given to the patient with meals, so that the medicines can bind with the phosphates in the stool and be eliminated.
