NSG5003 ADVANCED PATHOPHYSIOLOGY
COMPLETE QUESTION BANK
This premium study resource features a comprehensive
database of advanced pathophysiology exam questions
complete with clear answers and exhaustive, bold-italicised
rationales. Every entry is meticulously aligned with the core
modules of the NSG5003 curriculum from weeks 1 through
10 to guarantee mastery over complex cellular, systemic, and
genetic mechanisms. It serves as an high-yield study aid
explicitly formatted to optimize performance on graduate-
level nursing boards and advanced clinical assessments.
Q1. A 45-year-old male is admitted with acute ischemia of the
left lower extremity. At the cellular level, the lack of oxygen
directly impairs the oxidative phosphorylation pathway.
Which of the following is the most immediate consequence
of this metabolic failure?
A) Increased intracellular pH due to pyruvate accumulation
B) Failure of the Na+/K+ ATPase pump leading to cellular swelling
C) Decreased influx of extracellular calcium into the cytoplasm
D) Immediate rupture of the nuclear membrane
• Answer: B
• Rationale: Ischemia deprives the cell of oxygen, halting
oxidative phosphorylation and severely reducing ATP
, production. Without sufficient ATP, the energy-
dependent Na+/K+ ATPase pump fails. Sodium
accumulates inside the cell, creating an osmotic
gradient that draws water inward, causing acute cellular
swelling (hydropic degeneration). Intracellular pH
actually decreases due to anaerobic glycolysis and
lactic acid accumulation. Calcium influx increases rather
than decreases, activating destructive intracellular
enzymes. Nuclear membrane rupture occurs later during
irreversible cell death (necrosis), not as the most
immediate consequence.
Q2. During an autopsy of an elderly patient with a long
history of poorly controlled hypertension, the pathologist
notes a significant increase in the left ventricular wall
thickness without an increase in the number of
cardiomyocytes. This tissue adaptation is best classified as:
A) Hyperplasia
B) Physiological hypertrophy
C) Pathological hypertrophy
D) Metaplasia
• Answer: C
• Rationale: Hypertrophy refers to an increase in the size
of cells, resulting in an increase in the size of the organ.
Because cardiomyocytes have a highly limited capacity
for division, they adapt to the increased workload
(afterload) of chronic hypertension by synthesising
more structural proteins and myofibrils, increasing cell
size. Because this is a response to a chronic disease
state (hypertension) rather than a normal physiological
, stressor (like athletic training), it is classified as
pathological hypertrophy. Hyperplasia is an increase in
the number of cells. Metaplasia is the reversible
replacement of one mature cell type by another.
Q3. A 62-year-old female with a history of chronic hepatitis C
undergoes a liver biopsy. The pathology report notes the
presence of Councilman bodies, which represent
hepatocytes undergoing programmed cell death. Which
cellular enzyme family is directly responsible for executing
this process?
A) Caspases
B) Matrix metalloproteinases
C) Cyclin-dependent kinases
D) Lysosomal hydrolases
• Answer: A
• Rationale: Councilman bodies are apoptotic
hepatocytes. Apoptosis is a highly regulated,
programmed cell death pathway executed by a cascade
of proteolytic enzymes called caspases. Initiator
caspases activate executioner caspases, which
systematically cleave cellular proteins and activate
endonucleases to degrade DNA. Matrix
metalloproteinases are involved in extracellular matrix
remodelling. Cyclin-dependent kinases regulate the cell
cycle. Lysosomal hydrolases are primarily responsible
for autophagic digestion and heterolysis during
liquefactive or coagulative necrosis, not the clean
disassembly of apoptosis.
, Q4. A patient presents with severe right lower quadrant
abdominal pain, fever, and leukocytosis. An emergency
appendectomy is performed. Histopathological evaluation of
the excised appendix reveals a dense infiltration of
polymorphonuclear neutrophils within the muscularis
propria, accompanied by tissue liquefaction. What type of
necrosis is most characteristic of this acute bacterial
infection?
A) Coagulative necrosis
B) Caseous necrosis
C) Fat necrosis
D) Liquefactive necrosis
• Answer: D
• Rationale: Liquefactive necrosis is characteristic of
focal bacterial or fungal infections, as well as hypoxic
death of cells within the central nervous system.
Microbial substances and the rapid recruitment of
inflammatory cells (specifically neutrophils) release
potent hydrolytic enzymes that completely digest the
dead tissue, turning it into a liquid, viscous mass (pus).
Coagulative necrosis is typical of infarcts in solid
organs (excluding the brain) where tissue architecture is
preserved. Caseous necrosis is cheese-like and
characteristic of tuberculosis. Fat necrosis occurs from
pancreatic enzyme release or trauma to adipose tissue.
Q5. A 28-year-old female presents with persistent cough and
fatigue. A chest X-ray reveals hilar lymphadenopathy, and a
biopsy shows non-caseating granulomas containing
epithelioid histiocytes and Langhans giant cells. Which
