Answer to Question 1

ANS: C
The cholinergic fibers innervate the secretory glands; when stimulated, they produce serous and mucous secretions within the nostrils. Nasal dryness is the result of treatment with anticholinergic medications. Bleeding may be a result of overtreatment with anticholinergic medications, as a result of dryness of the nasal mucous membranes. Medications tend to dull olfactory function rather than enhance it.

Answer to Question 2

ANS: C
Antihistamines are used for inflammation and swelling resulting from the release of histamine during an antigen-antibody reaction. A grass allergy means that the patient experiences a release of histamine (antibody reaction) when exposed to the antigen, grass. Antitussive medications are for relief of cough. Expectorants are for the loosening of mucus so the patient can expel it by coughing. Decongestants would not help these symptoms as much as antihistamines.
