Answer to Question 1

D
Feedback:
B cells are programmed to identify specific proteins, or antigens. They provide what is called humoral immunity. Autoimmunity occurs when the body attacks its own self-cells. Passive immunity is the transfer of antibodies from one person to another. Active immunity is immunity produced by the body in response to an organism.

Answer to Question 2

D
Feedback:
Topical decongestants are sympathomimetics, meaning that they imitate the effects of the sympathetic nervous system to cause vasoconstriction, leading to decreased edema and reduced inflammation of the nasal membranes. They are available as nasal sprays that are used to relieve the discomfort of nasal congestion that accompanies the common cold, sinusitis, and allergic rhinitis. Topical nasal steroid decongestants are used for the treatment of allergic rhinitis and to relieve inflammation after the removal of nasal polyps. First- and second-generation antihistamines are not ordered for sinusitis.
