Question

A client with diabetic ketoacidosis is prescribed IV insulin. The potassium level is 2.9 mEq/L. Which action should the nurse anticipate before starting the insulin infusion?

Explanation
Insulin shifts potassium into cells and can worsen hypokalemia, increasing dysrhythmia risk. A potassium level of 2.9 mEq/L requires replacement and monitoring before or with insulin according to protocol. DKA also requires fluids and close monitoring, not discharge.

In-depth explanation

Clinical Judgment
In DKA, insulin treats acidosis but can make low potassium dangerous.

Memory Tip
Check potassium before insulin.

Clinical scenario

Clinical Practice Guide
DKA management includes fluids, insulin, potassium monitoring and replacement, glucose trends, and acid-base correction.

Caution
Hypokalemia can become life-threatening when insulin is started.
