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. "Avoid triggers that cause an attack" is correct because identifying and avoiding asthma triggers, such as allergens, smoke, pollution, or respiratory infections, is a fundamental component of asthma management. Trigger avoidance helps prevent exacerbations and reduces the need for rescue medications. B. "Use the peak expiratory flow meter once per week" is incorrect because a peak flow meter should be used daily or as directed by a provider, particularly during periods of worsening asthma, to monitor airflow and detect early signs of obstruction. Using it only once per week is insufficient for effective asthma management. C. "Take cromolyn sodium at the first sign of breathing difficulty" is incorrect because cromolyn sodium is a controller medication, not a rescue inhaler. It is used regularly to prevent inflammation, not for acute symptoms. Using it during an attack will not provide immediate relief. D. "You should stop playing basketball, but you can swim instead" is incorrect because children with asthma should not be restricted from physical activity if their condition is controlled. Exercise is encouraged, and proper pre-exercise use of a rescue inhaler or warm-up strategies can help prevent exercise-induced bronchospasm. Limiting activities unnecessarily can affect physical and social development.
