A client with diabetic ketoacidosis (DKA) receiving an insulin infusion has a blood glucose level of 450 mg/dL. The nurse monitors for which electrolyte imbalance as insulin begins to lower blood glucose?

✓ Correct Answer: Option B

Insulin causes potassium to shift from the extracellular to the intracellular compartment, leading to a decrease in serum potassium levels. Therefore, hypokalemia is a significant concern during DKA treatment.
