A nurse is caring for a client who has been hospitalized with an acute asthma exacerbation. What drug should the nurse expect to be ordered for immediate bronchodilation for this acute asthma situation?

Choice A reason: Albuterol is a short-acting beta2-agonist (SABA) that acts rapidly on the smooth muscles of the bronchioles to cause bronchodilation. In an acute asthma exacerbation, a nebulized solution provides direct delivery to the airways to relieve bronchospasm and improve airflow, making it the first-line "rescue" medication in emergency situations. Choice B reason: Oral prednisone is a corticosteroid used to reduce the systemic inflammation associated with asthma. While critical for preventing late-phase responses and reducing the duration of an exacerbation, it takes several hours to become effective and does not provide the immediate mechanical bronchodilation required during an acute attack. Choice C reason: Antibiotics are only indicated if the asthma exacerbation was triggered by a documented bacterial infection, such as pneumonia or sinusitis. They do not have any direct effect on the reactive airway disease or the bronchospasm itself, and therefore do not provide any relief for acute respiratory distress. Choice D reason: Antitussives (cough suppressants) are generally avoided in acute asthma. Coughing is often a protective mechanism to clear mucus, and suppressing it can lead to further airway obstruction or atelectasis. Furthermore, an antitussive does nothing to address the underlying bronchoconstriction that is causing the patient's respiratory symptoms.
