Final answer:
The statement by the adolescent indicating an understanding of insulin administration instructions is 'I rotate injection sites within the same region', as this practice helps prevent tissue damage and ensures consistent insulin absorption.
Step-by-step explanation:
The correct statement that would indicate an adolescent with type 1 diabetes mellitus understands the instructions for insulin administration and rotation sites is: b) I rotate injection sites within the same region.
Rotating injection sites helps to prevent the development of fatty deposits, also known as lipodystrophy, which can affect how insulin is absorbed. Using the same region ensures consistent absorption rates, while rotating within that region helps maintain healthy skin and tissue. The abdomen is a common area because it generally has a more consistent absorption rate, but it is just one of several sites that can be used, others include the thighs, buttocks, and arms. Reusing needles and injecting insulin into the same spot every time are incorrect practices that can lead to complications, including infections and variable insulin absorption.
People with type 1 diabetes must manage their condition carefully, monitoring their blood glucose levels frequently and administering insulin injections to reduce high blood glucose levels. Insulin injections facilitate the transport and storage of glucose which helps in lowering blood sugar levels. This is a lifelong requirement as there is currently no cure for type 1 diabetes.
