Final answer:
Asthma treatments include corticosteroids for long-term control and bronchodilators like norepinephrine for immediate relief, which confirms that option d) Answers b and c are correct.
Step-by-step explanation:
Treatments for obstructive pulmonary diseases like asthma might include corticosteroids and bronchodilators. Corticosteroids are anti-inflammatory medications that help control long-term symptoms by reducing swelling and mucus production in the airways, making them effective in managing asthma and preventing asthma attacks. Bronchodilators, such as those that contain norepinephrine, work by relaxing the muscles around the airways, thus opening them up and making it easier to breathe. They are also used as rapid relief from an acute asthma attack. Therefore, the answer to the question would be d) Answers b and c are correct.
