Practice Question

A nurse is mixing regular insulin and NPH insulin in the same syringe prior to administering it to a client who has diabetes mellitus. Which of the following actions should the nurse take first?

Answer Choices:

Correct Answer:

Inject air into the NPH vial.

Rationale:

💉When mixing NPH (cloudy) and regular (clear) insulin, the sequence prevents contamination of regular insulin with protamine from NPH.

☁️The first step is to inject air into the NPH vial, equal to the NPH dose, to maintain proper vial pressure without drawing any insulin yet.

🔄Next, inject air into the regular vial and then withdraw the regular insulin first, keeping the clear insulin free of NPH additives.

📏This sequence ensures accurate dosing and maintains insulin action profiles, reducing the risk of altered onset/peak.

📌Core Message

Start with air into NPH (cloudy), then handle the regular (clear) so the clear insulin stays uncontaminated and doses remain accurate.
