WEEK 1: Cellular Pathophysiology, Inflammation & Immunity
1. A patient presents with tissue swelling after a bee sting. This response is
mediated primarily by which type of hypersensitivity reaction?
A) Type I
B) Type II
C) Type III
D) Type IV
Correct ,,answer,,,: A
Rationale: A bee sting causes an immediate hypersensitivity reaction (Type I)
mediated by IgE antibodies binding to mast cells, triggering histamine release and
resulting in localized swelling, redness, and itching. Type I reactions are IgE-
mediated and occur within minutes.
,2. A 35-year-old woman with systemic lupus erythematosus (SLE) develops
glomerulonephritis. This manifestation is characteristic of which
hypersensitivity reaction?
A) Type I
B) Type II
C) Type III
D) Type IV
Correct ,,answer,,,: C
Rationale: SLE glomerulonephritis is a Type III hypersensitivity reaction
involving immune complex deposition (antigen-antibody complexes) in the
glomerular basement membrane, leading to complement activation and tissue
damage. Type III reactions are immune-complex mediated.
3. Which of the following best describes the role of p53 in cancer
development?
A) It promotes cell division
B) It functions as a tumor suppressor gene
C) It activates oncogenes
D) It increases angiogenesis
Correct ,,answer,,,: B
Rationale: p53 is a tumor suppressor gene that regulates the cell cycle and
prevents abnormal cell proliferation. It can initiate apoptosis in cells with damaged
DNA, thereby preventing cancer development.
,4. A patient with chronic alcohol abuse develops liver cirrhosis. The type of
necrosis most likely seen in this patient's liver is:
A) Coagulative necrosis
B) Liquefactive necrosis
C) Caseous necrosis
D) Fatty necrosis
Correct ,,answer,,,: A
Rationale: Coagulative necrosis is the most common type of necrosis seen in
ischemic injury and is characteristic of liver damage in chronic alcohol abuse. The
architecture of the tissue is preserved for several days, with dead cells becoming
eosinophilic and ghost-like.
5. Which type of necrosis is characteristic of hypoxic death in the brain?
A) Coagulative necrosis
B) Liquefactive necrosis
C) Caseous necrosis
D) Gangrenous necrosis
Correct ,,answer,,,: B
Rationale: Liquefactive necrosis is characteristic of hypoxic death in the brain.
The dead tissue is digested by hydrolytic enzymes, resulting in liquefaction and
cyst formation.
, 6. A patient with tuberculosis develops granulomas in the lungs. The necrosis
seen in these granulomas is most likely:
A) Coagulative necrosis
B) Liquefactive necrosis
C) Caseous necrosis
D) Fat necrosis
Correct ,,answer,,,: C
Rationale: Caseous necrosis is characteristic of tuberculosis and other
granulomatous diseases. The necrotic tissue has a cheese-like, white appearance
due to the combination of coagulative and liquefactive necrosis.
7. A 60-year-old patient with a history of smoking presents with a chronic
cough and weight loss. Chest X-ray reveals a lung mass. Biopsy shows atypical
cells with large, hyperchromatic nuclei. This finding is most consistent with:
A) Dysplasia
B) Metaplasia
C) Neoplasia
D) Hyperplasia
Correct ,,answer,,,: C
Rationale: Neoplasia refers to abnormal, uncontrolled cell growth. The presence
of atypical cells with large, hyperchromatic nuclei is characteristic of malignancy.
Dysplasia and metaplasia are reversible changes, while hyperplasia is an increase
in cell number.
