Final answer:
The correct technique for routine insulin injections is subcutaneous (SC) administration, which is essential for the home management of blood glucose levels in individuals with type 1 diabetes.
Step-by-step explanation:
The appropriate technique to teach a patient for routine insulin injection is Subcutaneous (SC). This method allows insulin to be absorbed slowly, providing a more controlled and steady reduction in blood glucose levels after a person with diabetes consumes a large or high-glucose meal. Subcutaneous injections are administered into the fatty tissue just below the skin, which is a convenient and less painful route for patients who need to self-administer insulin, as often required in type 1 diabetes.
People with type 1 diabetes must frequently monitor their blood sugar levels and administer insulin to bring their blood sugar back to normal. Insulin is a hormone produced by the pancreas that facilitates the uptake and storage of glucose in the cells, thereby decreasing blood glucose levels. Since there is no cure for type 1 diabetes, patients must continue insulin injections for life, often learning to administer these shots themselves. Subcutaneous administration is the most suitable and practical method for home administration of insulin.
