A nurse is preparing to mix short-acting insulin with NPH insulin from two vials. Which of the following actions should the nurse take?
Correct answer
A
Rationale
The correct action is to inject air into the short-acting insulin vial before withdrawing it. This is because it prevents the formation of a vacuum in the vial, making it easier to withdraw the correct dose. Ensuring the NPH insulin is drawn first (B) is incorrect because it may lead to contamination of one insulin with the other. Using two separate syringes (C) is unnecessary and increases the risk of dosing errors. Administering the insulin within 20 minutes (D) is not relevant to the mixing process.
