Which pharmacologic treatment is most appropriate to order initially for the client's acute respiratory condition?

• A. Oxygen therapy
• B. Nebulized bronchodilator
• C. Intravenous glucocorticoids
• D. Intravenous antibiotics

Answer: (B)

Rapid relief of bronchospasm is the priority in acute respiratory episodes. A fast-acting inhaled bronchodilator delivered by nebulizer directly relaxes airway smooth muscle, opens the airways, and improves airflow within minutes. That immediate improvement makes it the best initial pharmacologic choice. Oxygen therapy may be needed to correct low oxygen levels, but it’s a supportive measure rather than a medication. Intravenous glucocorticoids help with inflammation but take longer to work and are added after bronchospasm is addressed. Intravenous antibiotics are reserved for infection and aren’t the immediate need in pure bronchoconstriction.
