A nurse is preparing to administer regular and NPH insulin to a client. Which of the following actions should the nurse take?
Correct answer
A
Rationale
The correct answer is A: Withdraw the NPH insulin last. This is because regular insulin is a clear solution and should be withdrawn first to prevent contamination with the cloudy NPH insulin. Mixing the medications in a 3-mL syringe (B) is not recommended as it may alter the effectiveness of the insulin. Administering the medications in two separate syringes (C) is important to avoid mixing them prior to administration. Injecting air into the regular vial first (D) is unnecessary and not a standard practice.
