Question 1 of 5
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: B
Rationale: The correct answer is B: Inject air into the vial to withdraw the short-acting insulin. This step is essential to prevent creating a vacuum in the vial, making it difficult to withdraw the correct dose. Injecting air equal to the amount of insulin needed prevents negative pressure. Other choices are incorrect: A is not necessary as long as a vacuum is not created; C is not required if the same syringe is used for both insulins; and D is incorrect as NPH insulin is usually drawn last to prevent contamination.
