examinations by practicing with clinically relevant scenarios and evidence-based
rationales.
EXAM QUESTIONS
QUESTION 1: A 45-year-old patient presents with chronic hypertension. The
healthcare provider explains that sustained elevated blood pressure has led
to left ventricular hypertrophy. Which pathophysiological adaptation does
this represent?
A) Atrophy
B) Dysplasia
C) Hyperplasia
D) Hypertrophy
E) Metaplasia
CORRECT ANSWER: D - Hypertrophy
,RATIONALE: Hypertrophy is an increase in cell size in response to increased
workload or demand. In chronic hypertension, the left ventricle experiences
sustained increased pressure, causing individual cardiac myocytes to enlarge as an
adaptive response to maintain cardiac output. Atrophy is a decrease in cell size;
dysplasia is abnormal development; hyperplasia is an increase in cell number; and
metaplasia is replacement of one cell type with another. Hypertrophy represents
the appropriate adaptive mechanism in response to chronic hemodynamic stress.
QUESTION 2: A patient with severe burns covering 40% of body surface area
develops acute kidney injury within 24 hours. This is primarily due to which
pathophysiological mechanism?
A) Direct thermal injury to renal tissue
B) Myoglobinuria and hemoglobinuria causing acute tubular necrosis
C) Acute glomerulonephritis
D) Chronic pyelonephritis
E) Primary renal artery stenosis
CORRECT ANSWER: B - Myoglobinuria and hemoglobinuria causing acute
tubular necrosis
RATIONALE: Severe thermal burns cause massive tissue destruction, leading to
release of myoglobin from damaged muscle and hemoglobin from damaged red
blood cells. These large protein molecules overwhelm the renal tubular
reabsorption capacity, precipitate in the tubules, and cause direct tubular epithelial
damage (acute tubular necrosis). Additionally, hypovolemia from fluid loss in burns
further compromises renal perfusion. Direct thermal injury to kidneys is unlikely as
they are protected retroperitoneally. Options A, C, D, and E do not represent the
primary mechanism in acute burn injury.
QUESTION 3: Which of the following best describes the process of apoptosis in
comparison to necrosis?
,A) Apoptosis is uncontrolled and causes inflammation; necrosis is controlled and
does not cause inflammation
B) Apoptosis is controlled cell death without inflammation; necrosis is uncontrolled
cell death with inflammation
C) Both are identical processes occurring at the same rate
D) Apoptosis only occurs in cancer cells; necrosis occurs in normal cells
E) Necrosis is programmed; apoptosis is random
CORRECT ANSWER: B - Apoptosis is controlled cell death without
inflammation; necrosis is uncontrolled cell death with inflammation
RATIONALE: Apoptosis is programmed cell death (PCD) characterized by orderly
cell dismantling, fragmentation into apoptotic bodies, and removal by phagocytes
without triggering inflammation. Necrosis is uncontrolled cell death caused by
severe injury, leading to cell swelling, rupture, and release of intracellular contents
that trigger inflammatory responses. This distinction is clinically significant because
apoptosis maintains tissue homeostasis without causing collateral tissue damage,
while necrosis perpetuates tissue injury and inflammation. The other options
mischaracterize these fundamental biological processes.
QUESTION 4: A 52-year-old male with hypercholesterolemia develops
coronary artery atherosclerosis. At what stage does foam cell formation occur
in atherosclerotic plaque development?
A) Fatty streak stage
B) Fibrous plaque stage
C) Complicated lesion stage
D) Initial endothelial injury
E) Advanced calcification stage
CORRECT ANSWER: A - Fatty streak stage
, RATIONALE: Foam cells are macrophages that have engulfed oxidized low-density
lipoprotein (LDL) particles, appearing foamy under microscopy. They form early in
atherosclerosis during the fatty streak stage when circulating monocytes adhere to
areas of endothelial injury, differentiate into macrophages, and internalize oxidized
LDL. Fatty streaks are the earliest visible lesions and are considered potentially
reversible. While foam cells may persist in later stages, their initial and
characteristic formation occurs during the fatty streak stage. The other options
represent either earlier or later stages of plaque progression.
QUESTION 5: A patient develops Type 2 Diabetes Mellitus. Which
pathophysiological mechanism is most characteristic of this condition?
A) Autoimmune destruction of pancreatic beta cells
B) Insulin resistance with relative insulin deficiency
C) Complete absence of insulin secretion
D) Excessive glucagon secretion only
E) Pancreatic fibrosis preventing any hormone production
CORRECT ANSWER: B - Insulin resistance with relative insulin deficiency
RATIONALE: Type 2 Diabetes is characterized by insulin resistance (decreased
cellular response to insulin) combined with relative insulin deficiency (the pancreas
produces insufficient insulin to overcome the resistance). This is in contrast to Type
1 Diabetes, which involves autoimmune destruction of beta cells. In Type 2, the
pancreas retains some function but cannot produce enough insulin to maintain
normoglycemia. Genetic predisposition, obesity, and lifestyle factors contribute to
the development of insulin resistance. The other options describe different
metabolic disorders or Type 1 Diabetes pathophysiology.
QUESTION 6: A 68-year-old patient with COPD has a chronic arterial blood gas
showing pH 7.35, PaCO2 55 mmHg, HCO3- 30 mEq/L. What acid-base
disturbance is present?
