The patient is scheduled to receive insulin aspart and insulin detemir.
What is the correct procedure for the nurse to draw up the insulins for administration?

Mix the detemir and aspart in the same syringe, drawing up the aspart first.

Mix the detemir and aspart in the same syringe, drawing up the detemir first.

Draw up the aspart in one syringe and the detemir in another.

Draw up the detemir in one syringe and the aspart in another.

Answer and Explanation

The Correct Answer is C

Rationale for Choice A:

Mixing insulin detemir and insulin aspart in the same syringe is not recommended due to their differing physicochemical properties and potential for altered absorption and action profiles.

It's crucial to follow manufacturer guidelines, as mixing may lead to suboptimal glycemic control or unpredictable insulin activity.

Rationale for Choice B:

The order of mixing insulin detemir and insulin aspart, even if done incorrectly in the same syringe, would not significantly impact the overall contraindication of mixing them.

The primary concern remains the potential for altered pharmacodynamics and pharmacokinetics when these insulins are combined.

Rationale for Choice C:

Drawing up insulin aspart and insulin detemir in separate syringes is the correct procedure.

This approach ensures that each insulin maintains its intended action profile and absorption characteristics, leading to more predictable glycemic control.

It also aligns with best practices and guidelines for insulin administration.

Rationale for Choice D:

While drawing up insulin detemir first in a separate syringe is technically correct, it offers no specific advantage over drawing up insulin aspart first in a separate syringe.

The key principle is to avoid mixing the two insulins in the same syringe.

Correct Answer is D

Explanation

Choice A rationale:

Aspirating prior to injecting enoxaparin is not recommended.

Aspiration was once a common practice to check if a needle had entered a blood vessel.

However, research has shown that aspiration is not necessary for subcutaneous injections and may even be harmful. It can cause pain, bruising, and hematoma formation.

Additionally, aspirating can increase the risk of needlestick injuries.

For these reasons, aspiration is no longer recommended for subcutaneous injections of enoxaparin or other anticoagulants.

Choice B rationale:

Massaging the injection site after administering enoxaparin is not recommended. Massaging can increase the risk of bruising and hematoma formation.

It can also cause the medication to be absorbed too quickly, which can increase the risk of bleeding.

The best practice is to apply gentle pressure to the injection site with a dry gauze pad for a few seconds after the injection. This will help to prevent bleeding and bruising.

Choice C rationale:

The size of the syringe and needle used to administer enoxaparin is not specified in the question. However, a 1-mL syringe with a 32-gauge needle is a common choice for subcutaneous injections.

This size syringe is small enough to be easy to handle, and the 32-gauge needle is thin enough to minimize discomfort.

Choice D rationale:

The abdomen is the preferred site for subcutaneous injections of enoxaparin.

The abdomen has a large surface area of soft tissue, which makes it easy to inject the medication.

The abdomen is also relatively free of blood vessels and nerves, which reduces the risk of bruising, bleeding, and pain. Other potential injection sites for enoxaparin include the upper arms, thighs, and buttocks.

However, the abdomen is generally the preferred site.
