Question 1:
A patient with chronic hypertension develops left ventricular hypertrophy. This is an
example of which type of cellular adaptation?
A) Hyperplasia
B) Metaplasia
C) Hypertrophy
D) Dysplasia
Answer: C) Hypertrophy
Rationale: Hypertrophy is an increase in cell size in response to increased workload. In
hypertension, the left ventricle works against increased pressure, causing myocyte
enlargement. This is initially compensatory but can become pathologic if sustained.
Question 2:
Which event occurs FIRST in acute inflammation?
A) Leukocyte migration
B) Increased capillary permeability
C) Vasodilation
D) Phagocytosis
Answer: C) Vasodilation
Rationale: Vasodilation is the earliest vascular response in acute inflammation,
increasing blood flow to the injured area. This is followed by increased capillary
permeability, leukocyte migration, and phagocytosis .
,Question 3:
Which mediator is MOST responsible for increased vascular permeability during acute
inflammation?
A) Prostaglandins
B) Bradykinin
C) Histamine
D) Leukotrienes
Answer: C) Histamine
Rationale: Histamine, released from mast cells, is the primary early mediator causing
vasodilation and increased vascular permeability. Prostaglandins and leukotrienes
contribute to inflammation but are not the primary mediators of immediate vascular
permeability .
Question 4:
Apoptosis differs from necrosis because apoptosis:
A) Causes inflammation
B) Results in cell swelling
C) Is ATP-dependent
D) Damages surrounding tissue
Answer: C) Is ATP-dependent
Rationale: Apoptosis is an energy-dependent, programmed process that does not
provoke inflammation. Necrosis is unprogrammed, ATP-independent, and causes
inflammation. Apoptosis involves cell shrinkage and formation of apoptotic bodies .
Question 5:
The hallmark of chronic inflammation is:
A) Neutrophil predominance
B) Tissue regeneration
, C) Fibrosis and macrophage infiltration
D) Platelet aggregation
Answer: C) Fibrosis and macrophage infiltration
Rationale: Chronic inflammation features macrophages, lymphocytes, fibrosis, and
angiogenesis. Neutrophil predominance is characteristic of acute inflammation. Tissue
regeneration may occur but is not the hallmark .
Question 6:
Which mechanism explains fever development during infection?
A) Increased cortisol
B) Prostaglandin E2 acting on hypothalamus
C) Histamine release
D) Sympathetic nervous system activation
Answer: B) Prostaglandin E2 acting on hypothalamus
Rationale: Pyrogens stimulate the production of prostaglandin E2 (PGE2), which raises
the hypothalamic temperature set point, causing fever. Cortisol and histamine are not
directly responsible for fever generation .
Question 7:
Which electrolyte imbalance is MOST likely with extensive cell lysis?
A) Hypokalemia
B) Hyperkalemia
C) Hypocalcemia
D) Hypernatremia
Answer: B) Hyperkalemia
Rationale: Cell lysis releases intracellular potassium into the extracellular space, causing
hyperkalemia. This is a common complication of tumor lysis syndrome, rhabdomyolysis,
and massive tissue injury .
