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.
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 B
Explanation
Choice A rationale:
A lactose-free diet does not contraindicate acupuncture therapy. Lactose intolerance is a digestive condition that does not affect blood clotting or the ability to receive acupuncture safely.
Acupuncture needles are very fine and do not typically cause bleeding. Even if minor bleeding occurs, it is not a concern for individuals without bleeding disorders.
Therefore, a lactose-free diet does not pose a risk for acupuncture.
Choice B rationale:
Thrombocytopenia is a condition characterized by a low platelet count. Platelets are essential for blood clotting. Acupuncture involves the insertion of needles into the skin. This can cause minor bleeding, even when performed correctly.
In individuals with thrombocytopenia, even minor bleeding can be difficult to control and may lead to excessive bruising or hematoma formation.
Therefore, thrombocytopenia is a contraindication to acupuncture therapy due to the increased risk of bleeding complications.
Choice C rationale:
Herniated lumbar disks are a common condition that can cause back pain. Acupuncture is often used to treat back pain, including pain caused by herniated disks.
Studies have shown that acupuncture can be effective in reducing pain and improving function in patients with herniated disks.
Therefore, the presence of herniated lumbar disks does not contraindicate acupuncture therapy.
Choice D rationale:
Latex and strawberry allergies are not contraindications to acupuncture therapy. Acupuncture needles are typically made of stainless steel, which does not contain latex.
Additionally, acupuncture does not involve the use of strawberries or any other substances that are common allergens. Therefore, latex and strawberry allergies do not pose a risk for acupuncture.
