A patient is admitted to the emergency department with acute severe exacerbation of asthma. Which drug should the nurse anticipate will be included in the treatment plan?
A. Oral theophylline [Elixophyllin]
B. Subcutaneous omalizumab [Xolair]
C. Inhaled mometasone furoate [Asmanex]
D. High-dose albuterol [Proventil] via nebulizer treatment
Ans: D. High-dose albuterol [Proventil] via nebulizer treatment
Explanation: Nebulized high-dose SABAs, such as albuterol, are administered to relieve airflow obstruction. Oral theophylline is used for maintenance therapy of chronic stable asthma, not for treatment of exacerbation. Omalizumab is a second-line agent indicated for allergy-related asthma and only when preferred options have failed. Inhaled glucocorticoids, such as mometasone furoate, are not used to abort an acute attack. During an exacerbation they are administered systemically.
