The nurse is teaching a client with diabetes about self-care. Which activity does the nurse teach that can decrease insulin needs?

Choice A reason: Reducing liquid intake does not physiologically decrease the cellular requirement for insulin. In fact, adequate hydration is essential for patients with diabetes to help the kidneys excrete excess glucose. Dehydration can lead to concentrated blood glucose levels and potentially contribute to hyperosmolar hyperglycemic states or diabetic ketoacidosis in some patients. Choice B reason: Consuming animal organ meats does not provide a functional source of insulin. Insulin is a peptide hormone that is broken down by digestive enzymes in the gastrointestinal tract if ingested orally, rendering it biologically inactive. Furthermore, organ meats are often high in saturated fats and cholesterol, which may complicate the cardiovascular health of a diabetic patient. Choice C reason: Increasing carbohydrate intake directly increases the demand for insulin. Carbohydrates are metabolized into glucose, which requires insulin for transport into the cells. A higher glycemic load necessitates higher doses of exogenous insulin or increased endogenous secretion to maintain normoglycemia and prevent the deleterious effects of chronic or acute hyperglycemia. Choice D reason: Walking and other forms of aerobic exercise increase insulin sensitivity and facilitate glucose uptake by skeletal muscles via insulin-independent pathways, such as the translocation of GLUT4 transporters. By improving the body's efficiency in utilizing available glucose, regular physical activity can significantly reduce the overall daily requirement for exogenous insulin therapy.
