Question

Chris is teaching Derek and Deb about injection site rotation and insulin injection techniques. Which of the following statements by Derek indicates an understanding of the teaching?

a) "Insulin pens should be used on the same site for consecutive injections."
b) "Rotating injection sites helps prevent skin irritation and lipodystrophy."
c) "Injecting insulin deeply into muscles is recommended for better absorption."
d) "Using the same syringe for different types of insulin is a safe practice."

Answer 1

Derek displays his comprehension by acknowledging that rotating injection sites can prevent skin complications and ensure effective insulin absorption. Moreover, he understands that insulin is used to decrease, not increase, blood glucose levels after meals.

Step-by-step explanation:

The student, Derek, demonstrates an understanding of the teaching about injection site rotation and insulin injection techniques with his statement: "Rotating injection sites helps prevent skin irritation and lipodystrophy." This practice is essential for individuals who administer insulin regularly because using the same injection site repeatedly can lead to tissue damage under the skin, a condition known as lipodystrophy. Additionally, rotating sites ensures more consistent insulin absorption and aids in maintaining healthy skin.

It is important to clarify that insulin injections work to decrease blood glucose levels after a meal, contrary to the misinformation in statements c) and d). Insulin facilitates the uptake of glucose by cells, aiding in its storage and use, which ultimately lowers the blood glucose concentration.
