Part I: Cellular Adaptation, Injury, Inflammation & Immunity
(15 questions)
Q1: A 58-year-old man with a history of chronic hypertension presents for his annual
physical. His left ventricular wall thickness is noted to be increased on echocardiogram.
This cellular adaptation represents which of the following processes?
A. Hyperplasia, characterized by an increase in the number of cardiac myocytes
B. Hypertrophy, an increase in cell size without an increase in cell number [CORRECT]
C. Metaplasia, the replacement of cardiac muscle with fibrous connective tissue
D. Dysplasia, representing a pre-neoplastic change in ventricular tissue
Correct Answer: B
Rationale: Hypertrophy refers to an increase in cell size, not cell number. In response to
chronic pressure overload from hypertension, cardiac myocytes increase their
contractile protein content and organelle mass, leading to thicker ventricular walls.
,Hyperplasia (A) is incorrect because adult cardiac myocytes have limited regenerative
capacity and do not typically undergo hyperplasia. Metaplasia (C) involves replacement
of one differentiated cell type with another, which does not occur here. Dysplasia (D)
refers to disordered, pre-neoplastic growth and is not a normal adaptive response to
hemodynamic stress.
Q2: During a laboratory session, students are examining tissue samples from different
pathological processes. One slide shows preserved cellular architecture with loss of
nuclei and cytoplasmic eosinophilia in myocardial tissue. The professor explains this
represents coagulative necrosis. Which mechanism best explains the preservation of
tissue architecture in this type of cell death?
A. Rapid enzymatic digestion by released lysosomal enzymes causing tissue
liquefaction
B. Denaturation of structural proteins and enzymes preventing autolysis [CORRECT]
C. Ischemic injury primarily affecting the cell membrane with immediate cell lysis
D. Accumulation of calcium soaps following saponification of fatty acids
Correct Answer: B
Rationale: Coagulative necrosis results from ischemia that denatures structural proteins
and enzymes, effectively "fixing" the tissue and preventing the rapid autolysis seen in
liquefactive necrosis. The ghostly outlines of cells remain visible microscopically.
,Option A describes liquefactive necrosis (typical in brain infarcts or abscesses). Option
C is incorrect because coagulative necrosis involves more than just membrane damage.
Option D describes fat necrosis, which occurs in pancreatic or breast tissue.
Q3: A patient presents with fever, elevated white blood cell count, and increased
erythrocyte sedimentation rate following an episode of acute appendicitis. Which acute
phase reactant, produced by the liver in response to IL-6 stimulation, is most
responsible for the elevated ESR?
A. C-reactive protein, which opsonizes bacteria and activates complement
B. Fibrinogen, which promotes rouleaux formation of red blood cells [CORRECT]
C. Serum amyloid A, which recruits immune cells to sites of inflammation
D. Procalcitonin, which serves as a marker for bacterial infection
Correct Answer: B
Rationale: Fibrinogen is a large, asymmetric acute phase reactant that promotes
rouleaux formation—stacking of RBCs like coins—which increases the rate at which red
cells settle in the ESR test. While CRP (A) and serum amyloid A (C) are important acute
phase reactants, they do not directly affect ESR. Procalcitonin (D) is a marker for
bacterial infection severity but is not an acute phase reactant that influences
erythrocyte sedimentation.
, Q4: A 4-year-old child with a history of severe allergies to peanuts experiences
anaphylaxis after accidental ingestion. The rapid onset of bronchospasm, vasodilation,
and increased vascular permeability is mediated primarily by which immunological
mechanism?
A. IgG antibody-mediated activation of the classical complement pathway
B. IgE binding to mast cells with subsequent degranulation and histamine release
[CORRECT]
C. T-cell mediated cytotoxicity with direct cellular damage to respiratory epithelium
D. Immune complex deposition in pulmonary vessels activating the alternative
complement pathway
Correct Answer: B
Rationale: Type I hypersensitivity (anaphylaxis) involves allergen cross-linking of IgE
bound to FcεRI receptors on mast cells and basophils, triggering degranulation and
release of histamine, leukotrienes, and prostaglandins. This causes the classic triad of
vasodilation, increased vascular permeability, and smooth muscle contraction. IgG (A)
is not the primary antibody in immediate hypersensitivity. T-cell cytotoxicity (C)
describes Type IV hypersensitivity. Immune complex deposition (D) describes Type III
hypersensitivity.
