A nurse is caring for a child who is experiencing status asthmaticus. Which of the following interventions is the priority for the nurse to take?

A. Obtaining a peak flow reading is useful for assessing asthma severity but is not the immediate priority in an acute situation. B. Administering an inhaled glucocorticoid is part of the long-term management of asthma and may not provide immediate relief during an acute exacerbation. C. Administering a short-acting β-agonist (SABA) is the priority intervention for immediate relief of acute asthma symptoms and helps to quickly open the airways. D. Determining the cause of the exacerbation is important for long-term management but does not address the immediate need for symptom relief.
