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

Choice A reason: Regular physical activity, such as walking, improves insulin sensitivity and glucose uptake by muscle cells, thereby reducing the body's insulin requirements. Exercise is a cornerstone of diabetes management and helps maintain glycemic control. Choice B reason: Reducing fluid intake is not recommended for diabetic patients unless medically indicated. Dehydration can worsen hyperglycemia and increase the risk of diabetic ketoacidosis. Adequate hydration is essential for metabolic balance. Choice C reason: Severely limiting carbohydrate intake to 20 grams per day may lead to nutritional deficiencies and is not a standard recommendation for diabetes management. Balanced carbohydrate intake with portion control and monitoring is preferred. Choice D reason: Eating animal organ meats does not decrease insulin needs. While some organ meats contain trace amounts of insulin, they are not a reliable or safe source for managing diabetes. This practice is not supported by clinical guidelines.
