Part 1: Cellular Adaptation, Injury, Inflammation & Immunity
(Questions 1–15)
Q1: A 68-year-old male with chronic hypertension presents with left ventricular wall
thickening on echocardiogram. The cardiologist explains this represents an adaptive
response to increased afterload. Which cellular adaptation best describes this finding?
A. Atrophy resulting from decreased workload demands on the myocardium
B. Hypertrophy characterized by increased cell size without cell division
C. Hyperplasia involving increased cell number through mitosis
D. Metaplasia representing replacement of cardiac muscle with fibrous tissue
Correct Answer: B
Rationale: Hypertrophy is the increase in cell size (not number) in response to increased
functional demand, such as the heart working against elevated blood pressure. Atrophy
(A) involves cell shrinkage from decreased demand, which is opposite to this scenario.
Hyperplasia (C) involves increased cell number but cardiac myocytes are terminally
,differentiated and rarely divide. Metaplasia (D) involves replacement of one
differentiated cell type with another, not relevant here.
Q2: During a histology lab, a pathology resident observes coagulative necrosis in kidney
tissue from a patient who suffered acute myocardial infarction with cardiogenic shock.
What pathophysiologic mechanism explains why this type of necrosis preserves tissue
architecture?
A. Liquefactive necrosis from enzymatic digestion by bacterial proteases
B. Coagulative necrosis from denaturation of structural and enzymatic proteins
C. Caseous necrosis with cheese-like appearance from tuberculosis infection
D. Fat necrosis involving saponification of adipose tissue by released lipases
Correct Answer: B
Rationale: Coagulative necrosis results from ischemia (like shock) causing protein
denaturation that preserves tissue architecture temporarily, classically seen in solid
organs like kidney, heart, and spleen. Liquefactive necrosis (A) involves enzymatic
digestion seen in brain infarcts or abscesses. Caseous necrosis (C) is specific to TB
with amorphous granular debris. Fat necrosis (D) occurs in pancreatic or breast tissue
with calcium soap formation.
,Q3: A 45-year-old woman develops acute appendicitis. During the vascular phase of
acute inflammation, which chemical mediator is primarily responsible for the immediate
transient vasoconstriction followed by sustained vasodilation?
A. Bradykinin acting through the kinin-kallikrein system
B. Histamine released from mast cells and basophils
C. Prostaglandins synthesized via the cyclooxygenase pathway
D. Complement component C3a acting as an anaphylatoxin
Correct Answer: B
Rationale: Histamine is the primary mediator causing immediate vascular
changes—initial brief vasoconstriction followed by sustained vasodilation and increased
vascular permeability. While prostaglandins (C) and bradykinin (A) contribute to
vasodilation and pain, histamine dominates the immediate vascular phase. C3a (D) is
more involved in leukocyte chemotaxis and mast cell degranulation amplification.
Q4: A patient with a deep surgical incision healing by secondary intention demonstrates
granulation tissue formation. Which cell type is the predominant source of collagen
deposition during this proliferative phase of wound healing?
A. Neutrophils migrating from circulating blood to phagocytose bacteria
, B. Fibroblasts differentiating from mesenchymal stem cells in the wound bed
C. Epithelial cells migrating from wound edges to restore surface integrity
D. Endothelial cells forming new capillary loops in granulation tissue
Correct Answer: B
Rationale: Fibroblasts are the key collagen-producing cells during wound healing,
synthesizing types I and III collagen that provide tensile strength. Neutrophils (A) are
inflammatory cells present early, not collagen producers. Epithelial cells (C) restore
surface barrier function but don't produce significant collagen. Endothelial cells (D) form
new vessels (angiogenesis) but don't synthesize collagen matrix.
Q5: A 7-year-old child experiences anaphylaxis after eating peanuts, developing
urticaria, bronchospasm, and hypotension within minutes. This represents which type of
hypersensitivity reaction?
A. Type I hypersensitivity mediated by IgE and mast cell degranulation
B. Type II hypersensitivity involving antibody-mediated cytotoxicity
C. Type III hypersensitivity from immune complex deposition
D. Type IV hypersensitivity requiring T-cell mediated delayed response
