A 35-year-old female presents to the emergency department with severe dyspnea, wheezing, and accessory muscle use. She has a history of asthma and uses an albuterol inhaler. Her oxygen saturation is 88% on room air. Her peak expiratory flow (PEF) is 30% of her personal best. What is the most appropriate initial management step?
✓ Correct Answer: Option B
Initial management of severe asthma exacerbation includes supplemental oxygen, frequent or continuous inhaled short-acting beta-agonists (albuterol) and anticholinergics (ipratropium), and systemic corticosteroids. These interventions rapidly target bronchoconstriction and inflammation.
