A nurse is teaching an adolescent how to manage his cystic fibrosis. Which of the following statements by the adolescent indicates an understanding of the teaching?

A. "I will be excused from physical education class.": Physical activity is actually encouraged in adolescents with cystic fibrosis, as it helps improve lung function, mobilize secretions, and enhance overall health. Avoiding exercise would not support effective disease management. B. "I will limit my calcium intake to prevent kidney stones.": Children with cystic fibrosis are at risk for osteoporosis due to malabsorption of fat-soluble vitamins and poor bone health, not kidney stones from calcium. Adequate calcium intake is essential for bone strength. C. "I will take fewer enzymes when I eat high-fat foods.": Pancreatic enzymes should be taken with all meals and snacks, especially those high in fat, to aid in digestion and nutrient absorption. Taking fewer enzymes would worsen malabsorption and nutritional deficiencies. D. "I will increase my intake of vitamin D.": Fat-soluble vitamin deficiencies, including vitamin D, are common in cystic fibrosis due to malabsorption. Supplementing vitamin D supports bone health and calcium absorption.
