Which disorders are considered autoimmune?
(Select all that apply.)
a. Crohn disease
b. Addison disease
c. Rheumatoid arthritis
d. Systemic lupus erythematosus
e. Noninsulin-dependent diabetes - CORRECT ANSWER=a.
Exp: Crohn disease, Addison disease, rheumatoid arthritis, and systemic lupus
erythematosus are all diseases that result from autoimmune pathologic conditions. Insulin-
dependent diabetes is also an autoimmune disorder, but noninsulindependent diabetes is
not. page 264-265 Table 9-2
The common hay fever allergy is expressed through a reaction that is mediated by which
class of immunoglobulins?
a. IgE
,2 | Page
c. IgG
b. IgM
d. T cells - CORRECT ANSWER=a. IgE
Exp: Type I reactions are mediated by antigen-specific IgE and the products of tissue mast
cells (see figure 9-1). The most common allergies (e.g., pollen allergies) are type I
reactions. In addition, most type I reactions occur against environmental antigens and are
therefore allergic. The other options do not accurately identify the mediation factor related to
hay fever. page 263
Which type of antibody is involved in type I hypersensitivity reaction?
a. IgA
c. IgE
b. IgG
d. IgM - CORRECT ANSWER=c. IgE
Exp: Type I reactions are only mediated by antigen-specific IgE and the products of tissue
mast cells (see figure 9-1). page 263
Which statements are true concerning the humoral immune response? (Select all that
apply.)
a. The humoral immune response is divided into major and minor phases.
b. The response has IgG and IgM produced during each of its phrases.
c. It has a greater presence of IgG than IgM in one of its phases.

d. The humoral immune response is produced in reaction to the presence of an antigen.
e. Phases differ in their response time as a result of the effect of memory cells. -
CORRECT ANSWER=b. The response has IgG and IgM produced during each of its
phrases.
c. It has a greater presence of IgG than IgM in one of its phases.
d. The humoral immune response is produced in reaction to the presence of an antigen.
e. Phases differ in their response time as a result of the effect of memory cells.
Exp: The humoral immune response is divided into two phases, primary and secondary.
These phases differ in the relative amounts of IgG produced-the secondary response
having a significantly higher proportion of IgG relative to IgM. The two phases also differ in
the speed with which each occurs after the antigen challenge-the secondary phases is
significantly more rapid than the primary phase because of the presence of memory cells in
the secondary phase. page 247
Antibodies that are associated with mucosal immune system, such as immunoglobulins,
function to prevent which type of infections?
a. Infections that attack the respiratory system
b. Infections that tend to be chronic in nature
c. Infections likely to be resistant to antibiotics
d. Infections that focus on epithelial surfaces of the body - CORRECT ANSWER=d.
Infections that focus on epithelial surfaces of the body
Exp: Antibodies of the systemic immune system function throughout the body, whereas
antibodies of the secretory (mucosal) immune system-primarily immunoglobulins of the IgA
class-are associated with bodily secretions and function to prevent pathogenic infection on

epithelial surfaces. The other options are not necessarily true when considering the
immunoglobulins. page 252-253 Raynaud phenomenon is classified as a type III
hypersensitivity reaction and is due to:
a. Immune complexes that are deposited in capillary beds, blocking circulation
b. Mast cells that are bound to specific endothelial receptors, causing them to degranulate
and creating a localized inflammatory reaction that occludes capillary circulation
c. Cytotoxic T cells that attack and destroy the capillaries so that the" are unable to perfuse
local tissues
d. Antibodies that detect the capillaries as foreign protein and destroy them using lysosomal
enzymes and toxic oxygen species - CORRECT ANSWER=a. Immune complexes that
are deposited in capillary beds, blocking circulation
Exp: Raynaud phenomenon is a condition caused by the temperature-dependent deposition
of immune complexes in the capillary beds of the peripheral circulation.
None of the other options are involved in causing this condition. page 270
When the maternal immune system becomes sensitized against antigens expressed by the
fetus, that reaction occurs?
a. T-cell immunity
b. Alloimmunity
c. Fetal immunity
d. Autoimmunity - CORRECT ANSWER=b. Alloimmunity
