Answer to Question 1

ANS: C
The most rapid and severe immediate hypersensitivity type I reaction is anaphylaxis. Urticaria, or hives, is a dermal (skin) manifestation of allergic reactions. Hives and urticaria are similar re-sponses. ADCC is a mechanism that involves natural killer (NK) cells. Antibodies on the target cell are recognized by Fc receptors on the NK cells, which release toxic substances that destroy the target cell.

Answer to Question 2

ANS: B, D, E
Increased age is associated with diminished T-cell function, decreased immune function, dimin-ished production of antibody responses, decreased circulating immune complexes, and decreased ability to fight infection.
