Final answer:
The correct understanding of insulin injections is demonstrated by the patient's statement about rotating injection sites within the same region. Insulin is essential for the uptake of glucose to manage high blood sugar levels in people with diabetes, particularly those with type 1 diabetes who require it for life.
Step-by-step explanation:
A medical assistant is reinforcing teaching with a patient about the self-administration of insulin injections. When the patient states, "I'll rotate injection sites within the same region," it indicates a proper understanding of the teaching. This practice helps to prevent the formation of subcutaneous fatty lumps, which can occur if the same site is used repeatedly. Insulin, a hormone produced by the pancreas, facilitates the uptake of glucose by cells. When blood sugar levels rise after a meal, insulin assists in the transport and storage of glucose, effectively helping to lower blood glucose levels.
For those with type 1 diabetes, monitoring blood sugar levels is crucial, and insulin injections are required whenever blood sugar starts to get too high, as there is no cure for this condition. These injections are part of managing diabetes mellitus and may be crucial for life. It's important to note that insulin injections should not be administered into the muscle for faster absorption, nor should needles be reused. Moreover, insulin should not be taken only when blood sugar is very high, as consistent management is necessary.
