A nurse in a clinic sees a client who has an acute asthma exacerbation. Which of the following medications should reduce the symptoms?

A. Cromolyn is a mast cell stabilizer used for the prevention of asthma symptoms, not for acute exacerbations. B. Montelukast is a leukotriene receptor antagonist that is used as a maintenance medication, not effective for immediate relief during an acute asthma attack. C. Budesonide, an inhaled corticosteroid, is used for long-term control, not rapid relief in acute situations. D. Albuterol is a short-acting beta₂-agonist that provides rapid bronchodilation, making it the treatment of choice for acute asthma exacerbations.
