Question 1 of 5
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?
Correct Answer: A
Rationale: The correct answer is A: Inject air into the NPH vial. This step is crucial to prevent creating a vacuum in the vial when withdrawing the insulin. Injecting air into the NPH vial equalizes the pressure, making it easier to withdraw the insulin without causing leakage or difficulty in drawing up the correct dose. It ensures accurate measurement and prevents contamination.
Choice B is incorrect because withdrawing the NPH insulin before injecting air can create a vacuum in the vial, making it difficult to withdraw the correct dose.
Choice C is incorrect because regular insulin should be drawn after preparing the NPH insulin.
Choice D is incorrect because air should be injected into the NPH vial first.
