Answer to Question 1

ANS: D
One of the major causes of symptoms associated with an allergy is the release of histamine during the antigen-antibody reaction. Antihistamines suppress the symptoms of allergic reactions. Antibodies are not responsible for the allergic symptoms. Suppressing histamine diminishes the symptoms of allergies.

Answer to Question 2

ANS: B
Sneezing is a physiologic reflex used by the body to clear the nasal passages of foreign matter. Stimulation of the vagus nerve, stimulation of the tonsils, and enervation of the olfactory cranial nerve are not what initiate the sneezing reflex.
