What should be prioritized for a patient experiencing an asthma attack and showing signs of respiratory distress?

In a patient experiencing an asthma attack with signs of respiratory distress, the immediate priority is administering a bronchodilator. This medication works by relaxing the smooth muscles in the airways, leading to bronchodilation, which increases airflow and eases breathing. During an asthma attack, the airways become inflamed and constricted, making it crucial to act quickly to relieve this constriction and restore adequate airflow.

While the other measures, such as reassessing vital signs, providing oxygen therapy, and maintaining a calm environment, are important components of managing respiratory distress, they serve supportive roles rather than addressing the primary issue in an asthma attack. The bronchodilator directly targets the underlying cause of the respiratory distress by providing immediate relief, which is essential in emergencies. Once the patient's airway is stabilized, other interventions can be assessed and implemented as needed.
