A nurse is providing education to a school-age child who has a new diagnosis of asthma. Which of the following statements should the nurse include in the teaching?

Rationale: A. Avoiding triggers such as allergens, smoke, or exercise-induced triggers is a primary strategy in asthma management and prevention of exacerbations. B. The peak expiratory flow meter should be used daily or as prescribed, not once per week, to monitor asthma control effectively. C. Children with asthma should not be restricted from physical activity; exercise should be encouraged with proper preventive measures. D. Cromolyn sodium is a maintenance medication, not a rescue inhaler, and should be taken regularly for prevention, not at the first sign of an attack.
