Rationale: Treatment of hyperphosphatemia is directed at lowering serum levels. This is accomplished by either administering agents that bind phosphate in the gastrointestinal tract or administering an intravenous solution with saline since saline promotes the renal excretion of phosphate. The intravenous solution of choice for this patient would be 0.9% normal saline. The other intravenous solutions either do not contain saline or contain saline in insufficient amounts.
