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: C
Rationale: The correct answer is C: Inject air into the vial to withdraw the short-acting insulin. This is the correct action because when mixing short-acting insulin with NPH insulin, it is important to prevent contamination and ensure accurate dosing. By injecting air into the vial before withdrawing the short-acting insulin, the nurse prevents a vacuum from forming in the vial and makes it easier to withdraw the correct amount of insulin. This step helps maintain the integrity of both insulins and ensures accurate dosing.
Incorrect choices:
A: Administer the insulin within 20 min of preparing it - This is incorrect as insulin should be administered immediately after mixing.
B: Ensure the NPH insulin is drawn into the syringe first - This is incorrect as the short-acting insulin should be drawn first to prevent contamination.
D: Use two separate syringes to mix the insulin - This is incorrect as mixing in the same syringe is not recommended to avoid inaccurate dosing.
