Answer to Question 1

C
Unlike for asthma, short-acting beta2 adrenergic agonists often are prescribed on a schedule and as an additional rescue drug for the patient with COPD. Extra doses may be needed to open the airways whenever the patient feels especially breathless.

Answer to Question 2

C
Even though both drugs are beta2 agonists, they are both normally prescribed for the patient with asthma. Short-acting (but rapid-acting) beta2 agonists (albuterol) are used to reduce the severity or stop an asthma attack. Long-acting beta2 agonists (salmeterol) can prevent attacks when taken daily; however, their onset of action is so slow that these drugs are not helpful to stop an attack that has already started.
