A nurse is preparing regular and NPH insulin in the same syringe for a client who has diabetes mellitus. Which of the following actions should the nurse take?
Shake both insulin vials for 2 min before withdrawing the doses.
Administer the mixture within 5 min of preparing it.
Withdraw the NPH insulin before the regular insulin.
Inject air into the regular insulin vial before injecting air into the NPH vial.
None
None
The Correct Answer is B
A. Shaking insulin vials can cause bubbles and denature the insulin, especially NPH, which should be gently rolled between the hands to mix. Vigorous shaking can reduce effectiveness and increase the risk of inaccurate dosing.
B. Once regular and NPH insulin are drawn into the same syringe, the mixture should be administered promptly, ideally within 5 minutes, to maintain potency and prevent clumping. Delays can alter absorption and efficacy of the insulin.
C. The correct technique is to withdraw regular insulin first and then NPH, not the other way around. Drawing NPH first could contaminate the regular insulin vial with NPH, affecting rapid-acting insulin activity.
D. Air should be injected into each vial to equalize pressure before withdrawing the insulin, but the sequence should be air into NPH first, then air into regular insulin, to avoid contamination. Incorrect sequencing can introduce NPH into the regular insulin vial.

Correct Answer is C
Explanation
A. The client has been in the restraints for 4 hr. This is incorrect because the duration of restraint use is determined by the client's behavior and safety, not a set time frame. Restraints should be discontinued as soon as they are no longer necessary.
B. The client can explain the reasons for their behavior. This is incorrect because insight into behavior does not necessarily indicate that the client is no longer a danger to themselves or others.
C. The client is able to calmly follow commands. This is correct because the primary indication for removing restraints is when the client demonstrates self-control and the ability to follow directions, reducing the risk of harm.
D. The client reports that the restraints are too tight. This is incorrect because a complaint of tight restraints indicates a need for reassessment and possible adjustment, but not necessarily discontinuation.
Correct Answer is A
