Final answer:
The correct answer to the question is a. Bronchodilators, oxygen. Bronchodilators help open the airways, while supplemental oxygen may be needed for those with severely compromised breathing.
Step-by-step explanation:
Treatments for chronic obstructive pulmonary disease (COPD) include bronchodilators and anti-inflammatory drugs. Sometimes supplemental oxygen must be given. Therefore, the correct answer is a. Bronchodilators, oxygen. Bronchodilators are inhaled medications that help to soothe and expand the constricted airways, making it easier for patients to breathe. In addition to bronchodilators, anti-inflammatory drugs such as corticosteroids can be administered to reduce inflammation in the airways. For COPD patients whose breathing is severely compromised, doctors may prescribe the use of supplemental oxygen to ensure that the body receives the necessary amount of oxygen.
