A patient is admitted to the cardiac unit.


Everyone admitted to the cardiac unit will have an EKG done unless otherwise ordered. This is an example of which type of order?

Choice A rationale:

Incorrect. Mixing insulin detemir and insulin aspart in the same syringe is generally not recommended due to the following reasons:

Altered Pharmacokinetics: Mixing insulins can potentially alter their absorption and action profiles, leading to unpredictable blood glucose control.

Stability Concerns: The compatibility of different insulins in a mixed solution is not always guaranteed, potentially leading to precipitation or decreased potency.

Dosing Accuracy: Drawing up mixed insulins accurately can be challenging, especially when different dosages are required for each type.

Manufacturer Recommendations: Insulin manufacturers typically advise against mixing different insulins unless specifically instructed by a healthcare professional.

Choice B rationale:

Incorrect. While the order of drawing up insulins may have a minor impact on mixing, it does not address the fundamental concerns of mixing different insulins in the same syringe. The primary issue is the potential for altered pharmacokinetics, stability concerns, and dosing accuracy, as explained in the rationale for Choice A.

Choice D rationale:

Incorrect. Rolling insulin bottles between the palms is a technique used to gently resuspend insulin particles that may have settled at the bottom. However, it does not pertain to the correct procedure for drawing up different insulins for administration.

Choice C rationale:

Correct. Administering insulin detemir and insulin aspart using separate syringes and different injection sites is the most appropriate approach for several reasons:

Maintains Pharmacokinetics: It ensures that each insulin maintains its intended absorption and action profile, promoting optimal blood glucose control.

Ensures Stability: Using separate syringes eliminates the risk of potential incompatibility issues that could arise from mixing insulins.

Promotes Dosing Accuracy: Drawing up insulins in separate syringes allows for greater precision in administering the correct dosage of each type.

Aligns with Manufacturer Guidelines: This approach adheres to the recommendations of insulin manufacturers, ensuring safe and effective administration.

Additional Considerations:

Nurses should always consult the latest insulin administration guidelines and individual patient needs for optimal care.

Proper education and counseling should be provided to patients who require multiple insulin injections to ensure adherence and understanding of correct administration techniques.

Step 1: Convert the prescribed dose to milligrams. 400 mcg = 0.4 mg (since 1 mg = 1000 mcg)

Step 2: Compare the prescribed dose to the pill strength. The prescribed dose is 0.4 mg.

The pill strength is 0.4 mg.

Step 3: Determine the number of pills needed.

Since the prescribed dose and pill strength are equal, only one pill is needed to administer the correct dose.

Rationale for Choice A:

Correct: One pill of 0.4 mg will provide the exact dose of 400 mcg that has been prescribed.

Direct match: The pill strength matches the prescribed dose, eliminating the need for any calculations or adjustments.

Therapeutic equivalence: Administering one pill ensures that the patient receives the intended amount of medication to achieve the desired therapeutic effect.

Adherence to prescription: Conforms to the healthcare provider's instructions, promoting accurate and safe medication administration.
