A patient with chronic kidney disease has a potassium level of 6.2 mEq/L. Which immediate intervention should the nurse anticipate?

✓ Correct Answer: Option B

IV insulin with dextrose rapidly shifts potassium from the extracellular to the intracellular space, providing a quick, temporary reduction in serum potassium. While other options may be used, insulin and dextrose provide immediate stabilization.
