The nurse notes a reddened area on the right heel that does not turn lighter in color when pressed with a finger.


Which term will the nurse use to describe this area?

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.

Choice A rationale:

Splinting the incision when coughing helps to minimize pain and discomfort, which can encourage deeper breathing and coughing. This is essential because deep breathing and coughing help to clear secretions from the lungs and prevent atelectasis (collapse of lung tissue).

Steps for splinting the incision:

Place a pillow or folded towel over the incision site.

Instruct the patient to apply gentle pressure to the pillow or towel with their hands when coughing or deep breathing. Encourage the patient to relax their abdominal muscles during coughing and deep breathing exercises.

Choice B rationale:

Sitting up in a chair and ambulating promote lung expansion and help to mobilize secretions. This is because gravity assists in moving secretions from the smaller airways into the larger airways, where they can be more easily coughed up.

Additional benefits of sitting up and ambulating: Improved circulation

Decreased risk of pneumonia Enhanced recovery from surgery Choice C rationale:

Using an incentive spirometer hourly helps to increase lung capacity and prevent atelectasis. The device encourages the patient to take slow, deep breaths, which helps to inflate the alveoli (air sacs) in the lungs.

Instructions for using an incentive spirometer:

Sit upright in a chair or bed.

Place the mouthpiece of the spirometer in your mouth and seal your lips around it.

Inhale slowly and deeply through the mouthpiece, aiming to raise the piston inside the device as high as possible. Hold your breath for 3-5 seconds.

Exhale slowly and completely through the mouthpiece.

Repeat the process 10-15 times per hour, or as instructed by your healthcare provider.
