Answer to Question 1

ANS: B
Expectorants stimulate the flow of respiratory tract secretions to improve cough productivity. Guaifenesin does not dry secretions, because it does not have anticholinergic effects. Guaifenesin does not alleviate pain associated with cough. Guaifenesin does not stimulate immune responses.

Answer to Question 2

ANS: B
Intranasal glucocorticoids, such as fluticasone propionate, are the most effective drugs for prevention and treatment, because they prevent or suppress all the major symptoms of allergic rhinitis (congestion, rhinorrhea, sneezing, nasal itching, and erythema). Pseudoephedrine is an oral sympathomimetic used to reduce nasal congestion associated with allergic rhinitis. It has no effect on other symptoms. Loratadine, an oral antihistamine, reduces sneezing, rhinorrhea, and nasal itching only and is less effective than intranasal glucocorticoids. Intranasal cromolyn sodium is moderately effective in the treatment of allergic rhinitis, but the benefits are much less than those of intranasal glucocorticoids.
