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: C
Rationale: The correct answer is C: Inject air into the NPH vial. This step is crucial to prevent creating a vacuum in the vial when withdrawing the NPH insulin, ensuring accurate dosage measurement. Injecting air into the NPH vial equalizes pressure, making it easier to withdraw the correct amount of insulin without causing air bubbles.
Choice A is incorrect as withdrawing regular insulin first may lead to air being drawn into the syringe when withdrawing NPH insulin.
Choice B is incorrect because withdrawing NPH insulin first without equalizing pressure may cause difficulty in drawing the correct amount of insulin.
Choice D is incorrect as injecting air into the regular insulin vial before withdrawing NPH insulin is unnecessary and may introduce air bubbles into the syringe.
