Question 1 of 5
A nurse is preparing to mix NPH insulin and regular insulin for administration. Which of the following actions should the nurse take?
Correct Answer: B
Rationale: The correct answer is B: Inject air into each vial. This is the correct action because it prevents creating a vacuum in the vial, making it easier to withdraw the insulin. Injecting air into the vial equalizes the pressure, allowing for smooth and accurate withdrawal of the desired amount of insulin. Option A is incorrect because a tuberculin syringe is not necessary for mixing insulin. Option C is incorrect because the regular insulin should be withdrawn first to prevent contamination. Option D is incorrect as shaking the regular insulin vial may cause bubbles or denature the insulin.
