Which of the following medications should the nurse expect to administer first?

The correct answer is B: Albuterol. Albuterol is a short-acting beta-agonist bronchodilator used for acute bronchospasm, making it the priority to administer first in a patient experiencing respiratory distress. It acts quickly to dilate the airways and improve airflow, providing immediate relief. Budesonide (A) and Fluticasone (C) are inhaled corticosteroids used for long-term control and prevention of asthma symptoms, not for immediate relief. Montelukast (D) is a leukotriene receptor antagonist used for chronic asthma management, also not for acute exacerbations. In summary, Albuterol is the most appropriate choice for immediate relief of bronchospasm in an emergency situation.
