Final answer:
The subject of the question is the correct use and administration order of bronchodilators and glucocorticoids in respiratory therapy for conditions like asthma and bronchitis. Bronchodilators are used first to open airways, followed by glucocorticoids for long-term control.
Step-by-step explanation:
The question pertains to the administration of medications for managing respiratory conditions such as asthma and bronchitis. Bronchodilators are inhaled medications that act rapidly to dilate constricted airways, making breathing easier during an asthma attack. Following this, glucocorticoids like beclomethasone dipropionate are then administered to exert a longer-term anti-inflammatory effect to control the disease. While there is currently no cure for asthma, these medications help to manage symptoms and prevent attacks. For illnesses such as bronchitis, treatments include hydration, humidifiers, and expectorants that help clear mucus from the airways, as opposed to cough suppressants which may inhibit the clearance of mucus.
