Answer to Question 1

ANS: A
The short-acting beta agonists have a rapid onset (few minutes) and are used to treat acute bronchospasm. Beta agonists are not used to treat allergies. Decongestants are used for nasal congestion. Long-acting beta agonists are used for exertional dyspnea.

Answer to Question 2

ANS: C
The patient is not tolerant to the drug if the serum theophylline levels are too low. Cimetidine would enhance the effects of theophylline, not decrease the effects. Smoking reduces the therapeutic effects of xanthine derivatives, including theophylline. Overuse of the inhaler would cause a high level of serum theophylline.
