Section 1: Immunology & Hypersensitivity Reactions (Questions 1-25)
Question 1: Hypersensitivity is best defined as a(an):
A. Disturbance in immunologic tolerance of self-antigens
B. Immunologic reaction of one person to tissue of another person
,C. Altered immunologic response to an antigen that results in disease
D. Undetectable immune response in the presence of antigens
Correct ,,answer,,,,: C
Rationale: Hypersensitivity represents an excessive or inappropriate immune
response to an antigen that causes tissue damage and disease. This differs from
normal immunity, which protects without harming the host .
Question 2: Which antibody is involved in Type I hypersensitivity reactions?
A. IgA
B. IgE
C. IgG
D. IgM
Correct ,,answer,,,,: B
Rationale: Type I hypersensitivity is mediated by IgE antibodies that bind to mast
cells and basophils. Upon re-exposure to the allergen, cross-linking of IgE triggers
degranulation and release of histamine, leukotrienes, and prostaglandins .
Clinical Correlation: Type I reactions include anaphylaxis, asthma, urticaria
(hives), and allergic rhinitis. First-line treatment for anaphylaxis is epinephrine .
Question 3: A patient presents with widespread itching, rash, and wheezing within
minutes of eating peanuts. This is an example of which hypersensitivity type?
A. Type I
B. Type II
,C. Type III
D. Type IV
Correct ,,answer,,,,: A
Rationale: The rapid onset (minutes after exposure) with IgE-mediated mast cell
degranulation is characteristic of Type I hypersensitivity. Wheezing indicates
bronchoconstriction, and the rash represents urticaria .
Question 4: A patient develops a severe hemolytic transfusion reaction after
receiving mismatched blood. This represents which hypersensitivity type?
A. Type I
B. Type II
C. Type III
D. Type IV
Correct ,,answer,,,,: B
Rationale: Type II hypersensitivity is cytotoxic, mediated by IgG or IgM
antibodies binding to antigens on cell surfaces, leading to complement activation
and cell destruction. In incompatible blood transfusion, recipient antibodies destroy
donor RBCs .
Additional Examples: Graves' disease (antibodies stimulate TSH receptors
without destroying tissue), autoimmune hemolytic anemia, Goodpasture
syndrome .
, Question 5: Which statement correctly differentiates Type II from Type III
hypersensitivity?
A. Type II involves T cells; Type III involves B cells
B. Type II is organ-specific (antibody binds cell surface antigen); Type III is
not organ-specific (antigen-antibody complexes deposit in tissues)
C. Type II is delayed; Type III is immediate
D. Type II involves IgE; Type III involves IgG
Correct ,,answer,,,,: B
Rationale: Type II antibodies target antigens on specific cell surfaces (organ-
specific). Type III involves soluble antigens that form immune complexes in
circulation, which then deposit in vessel walls, joints, and glomeruli .
Question 6: Systemic Lupus Erythematosus (SLE) is primarily associated with
which hypersensitivity type?
A. Type I
B. Type II
C. Type III
D. Type IV
Correct ,,answer,,,,: C
Rationale: SLE is a classic Type III hypersensitivity disorder where
autoantibodies (ANA, anti-dsDNA) form immune complexes that deposit in
multiple organs, including kidneys (proteinuria), skin (malar rash,
photosensitivity), joints (non-erosive arthritis), and serosa (serositis) .
Key SLE Features: Malar rash, discoid rash, photosensitivity, oral ulcers,
arthritis, serositis, renal disorders, neurologic disorders, hematologic disorders .
