The nurse caring for a patient in acute renal failure should expect hypertonic glucose, insulin infusions, and sodium bicarbonate to be used to treat:
A) Hypernatremia
B) Hypokalemia
C) Hyperkalemia
D) Hypercalcemia
Ans: C
Feedback: Hyperkalemia is a common complication of acute renal failure. It's life-threatening if immediate action isn't taken to reverse it. The administration of glucose and regular insulin, with sodium bicarbonate if necessary, can temporarily prevent cardiac arrest by moving potassium into the cells and temporarily reducing serum potassium levels. Hypernatremia, hypokalemia, and hypercalcemia don't usually occur with acute renal failure and aren't treated with glucose, insulin, or sodium bicarbonate.
