Question 1:
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 permeability during acute inflammation. Prostaglandins and
leukotrienes contribute to inflammation but are not the primary mediators of immediate
vascular permeability .
Question 2:
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 3:
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 4:
Which process 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 5:
Granuloma formation is most associated with:
, A) Acute bacterial infections
B) Viral infections
C) Persistent intracellular pathogens
D) Allergic reactions
Answer: C) Persistent intracellular pathogens
Rationale: Granuloma formation is a hallmark of chronic inflammation, particularly in
response to persistent intracellular pathogens such as Mycobacterium tuberculosis and
fungi. Macrophages and T lymphocytes aggregate to contain the pathogen .
Question 6:
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 .
Question 7:
The strongest risk factor for autoimmune disease development is:
A) Age
B) Female sex
C) Obesity
D) Viral exposure
Answer: B) Female sex
