ANS: B
Treatment for hyperkalemia includes infusion of a calcium salt to offset the effects of hyperkalemia on the heart and infusion of glucose and insulin to promote uptake of potassium by the cells.
A potassium-sparing diuretic would increase the serum potassium level even more.
The patient would not require hypotonic fluids to reduce hyperkalemia. In fact, with subsequent hyponatremia, the potassium level might increase more.
Calcium salts, not magnesium salts, would be used to manage the patient's hyperkalemia.
