A client with a history of asthma reports having episodes of bronchoconstriction and increased mucus production while exercising. Which action should the nurse implement?

A. Review the client’s routine asthma management prescriptions: Reviewing daily medications is important for long-term asthma control but does not immediately address the trigger of exercise-induced bronchospasm. The priority is to ensure preventive action before exertion. B. Assess client for signs and symptoms of upper airway infection: Infections can worsen asthma, but the client specifically describes symptoms triggered by exercise. This makes infection assessment less relevant to the immediate concern. C. Teach client to use pursed lip breathing when episodes occur: Pursed lip breathing helps with air trapping in COPD, but it does not prevent exercise-induced bronchoconstriction. Relying on this technique during an acute episode is not as effective as pre-exercise prophylaxis. D. Determine if the client is using an inhaler before exercising: Using a short-acting bronchodilator before activity prevents exercise-induced bronchospasm by relaxing airway muscles and improving airflow. Confirming correct inhaler use is the most appropriate nursing action.
