A nurse is preparing regular and NPH insulin in the same syringe for a client who has diabetes mellitus. Which of the following actions should the nurse take?
Correct answer
B
Rationale
The correct answer is B: Administer the mixture within 5 min of preparing it. This is important because regular insulin should always be drawn up before NPH insulin due to the risk of contaminating the regular insulin with NPH. Administering the mixture promptly ensures the insulin remains stable and effective.
Choice A is incorrect because shaking the vials can cause air bubbles and lead to inaccurate dosing. Choice C is incorrect as NPH insulin should be drawn up after regular insulin to avoid contamination. Choice D is incorrect as air should be injected into the vial after withdrawing insulin to prevent creating a vacuum.
