A nurse in an urgent care center is caring for a client who is having an acute asthma exacerbation. Which of the following actions is the nurse's highest priority?

Rationale: A. Administering nebulized albuterol is correct because it is a short-acting beta-agonist (SABA) that provides rapid bronchodilation. During an acute asthma exacerbation, airway constriction is the immediate threat to oxygenation. According to Airway-Breathing-Circulation (ABC) priorities, relieving bronchospasm to restore airflow takes precedence over other supportive measures. Prompt administration of albuterol can quickly improve ventilation, reduce wheezing, and stabilize the patient. B. Providing immediate rest for the client is incorrect because while reducing physical activity can help conserve energy, it does not directly relieve bronchospasm or improve airflow. Rest alone is not sufficient during an acute exacerbation. C. Positioning the client in high-Fowler's is incorrect as a sole intervention because it can assist with breathing by maximizing lung expansion, but it does not treat the underlying airway constriction, which is the priority during an acute exacerbation. D. Initiating oxygen therapy is incorrect as the highest priority in this scenario. Oxygen helps maintain oxygen saturation, but if the airway remains constricted due to bronchospasm, oxygen delivery alone will not correct hypoxemia effectively. Bronchodilation with albuterol addresses the root cause of airflow obstruction.
