A nurse is providing teaching to a 14-year-old adolescent who has a new diagnosis of type 1 diabetes mellitus. Which of the following statements by the adolescent indicates an understanding of the teaching?

A. "I will increase my food intake before I exercise.": This indicates understanding, as additional carbohydrates may be needed before physical activity to prevent exercise-induced hypoglycemia. Adolescents with type 1 diabetes must learn to balance insulin, food intake, and activity. B. "As long as I take my insulin, I can eat whatever I want.": Insulin helps manage blood glucose, but dietary choices still matter. Consuming high-sugar or high-fat foods can lead to poor glycemic control, even with insulin administration. C. "As I get older, my sugar levels will automatically decrease.": Blood glucose levels do not automatically improve with age. Diabetes management remains essential throughout life and often requires adjustments during puberty due to hormonal changes. D. "The blood pressure medicine I'm taking will help to keep my insulin level low.": Antihypertensives do not regulate insulin levels. Insulin therapy must be managed separately, and medications for blood pressure address cardiovascular risk, not glycemic control.
