Question 1 of 5
A nurse is preparing to administer regular insulin 4 units and NPH insulin 10 units subcutaneously to a client who has type 1 diabetes mellitus. Which of the following actions should the nurse take first?
Correct Answer: C
Rationale: The correct answer is C: Inject 4 units of air into the regular insulin vial. This action is done to prevent negative pressure in the vial, making it easier to withdraw the correct dose of insulin. By injecting air first, the nurse ensures that the exact amount of insulin can be withdrawn accurately without causing any damage to the vial or affecting the dose.
Choice A is incorrect as injecting air into the NPH insulin vial is not necessary before drawing up the insulin.
Choice B is incorrect as drawing up the NPH insulin before preparing the regular insulin would be out of sequence.
Choice D is incorrect as drawing up the regular insulin before injecting air into the vial could lead to difficulty in withdrawing the correct dose.
