Pathophysiology Chapter 09 - Alterations in Immunity and Inflammation
1. How is hypersensitivity best defined?
a. A disturbance in the immunologic tolerance of self-antigens
b. An immunologic reaction of one person to the tissue of another person
c. An altered immunologic response to an antigen that results in disease
d. An undetectable immune response in the presence of antigens
2. What is a hypersensitivity reaction that produces an allergic response called?
a. Hemolytic shock
b. Anaphylaxis

d. Systemic erythematosus
3. The common hay fever allergy is expressed through a reaction that is mediated by which
class of immunoglobulins?
a. IgE
b. IgG
c. IgM
d. T cells
4. What are blood transfusion reactions an example of?
a. Autoimmunity
b. Alloimmunity
