Question 1 of 5

The client is receiving a continuous infusion of insulin for diabetic ketoacidosis. Which laboratory value should the nurse monitor most closely?

Correct Answer: A

Rationale: Insulin therapy in diabetic ketoacidosis shifts potassium into cells, risking hypokalemia, which can cause arrhythmias. Sodium, BUN, and A1C are monitored but are less critical during acute treatment.

Diuretics are used with caution to avoid causing hypovolemia. Antidysrhythmics are typically needed to treat both atrial and ventricular dysrhythmias.
