Question 1: A 72-year-old male with a history of hypertension presents with a
sudden onset of severe, tearing chest pain radiating to his back. His blood
pressure is 180/100 mmHg in his right arm and 130/80 mmHg in his left arm.
Which of the following pathophysiological processes is most likely responsible
for his presentation?
A. Rupture of an atherosclerotic plaque in the coronary artery
B. Dissection of the tunica media of the aorta
C. Occlusion of the pulmonary artery by a thrombus
D. Spasm of the esophageal smooth muscle
CORRECT ANSWER: B. Dissection of the tunica media of the aorta
Rationale: The patient's presentation of acute, tearing chest pain radiating to the back,
along with a differential blood pressure between arms, is classic for an aortic dissection.
This occurs when a tear in the intima allows blood to enter the tunica media, creating a
false lumen that can propagate and compromise branch vessels, leading to pulse deficits.
Question 2: A 65-year-old female with a long history of type 2 diabetes
mellitus is diagnosed with chronic kidney disease. Her hemoglobin A1c is
9.2%. Which of the following best describes the primary mechanism by which
chronic hyperglycemia contributes to her renal pathology?
A. Non-enzymatic glycosylation of basement membrane proteins leading to thickening
B. Direct toxic effect of glucose on the glomerular podocytes
C. Autoimmune destruction of the renal tubules
D. Ischemic injury due to macrovascular atherosclerosis
CORRECT ANSWER: A. Non-enzymatic glycosylation of basement membrane
proteins leading to thickening
Rationale: Chronic hyperglycemia leads to the formation of advanced glycation end-
products (AGEs) through non-enzymatic glycosylation. These AGEs accumulate in the
glomerular basement membrane, causing thickening and increased permeability, which
is a hallmark of diabetic nephropathy. This process also stimulates mesangial expansion
and fibrosis.
Question 3: A patient with a history of heart failure develops ascites and
peripheral edema. This fluid accumulation is primarily due to which of the
following pathophysiological mechanisms?

A. Decreased plasma oncotic pressure due to liver failure
B. Increased hydrostatic pressure in the venous system
C. Increased capillary permeability due to systemic inflammation
D. Lymphatic obstruction causing impaired fluid return
CORRECT ANSWER: B. Increased hydrostatic pressure in the venous system
Rationale: In heart failure, the heart's inability to pump effectively leads to a backup of
blood, increasing venous hydrostatic pressure. This elevated pressure forces fluid out of
the capillaries and into the interstitial space, leading to edema and, when severe in the
liver and portal circulation, ascites.
Question 4: A 45-year-old male presents with jaundice, dark urine, and clay-
colored stools. Laboratory tests reveal elevated direct bilirubin and alkaline
phosphatase. This clinical picture is most consistent with which type of
jaundice?
A. Pre-hepatic jaundice
B. Hepatic jaundice
C. Post-hepatic (obstructive) jaundice
D. Unconjugated hyperbilirubinemia
CORRECT ANSWER: C. Post-hepatic (obstructive) jaundice
Rationale: The presence of dark urine, clay-colored stools, and elevated direct
(conjugated) bilirubin with a high alkaline phosphatase indicates an obstruction in the
biliary tree. This prevents conjugated bilirubin from reaching the intestines, where it is
normally converted to urobilinogen (causing brown stool), and it backs up into the
blood, being excreted in the urine.
Question 5: A patient with severe sepsis develops acute respiratory distress
syndrome (ARDS). Which of the following pathophysiological changes is the
hallmark of this condition?
A. Increased alveolar surface tension due to surfactant deficiency
B. Diffuse alveolar damage leading to increased capillary permeability
C. Bronchoconstriction and mucus hypersecretion
D. Atelectasis due to obstruction of airways by a foreign body

Material
CORRECT ANSWER: B. Diffuse alveolar damage leading to increased capillary
permeability
Rationale: ARDS is characterized by an acute inflammatory response in the lung
parenchyma, often triggered by a systemic insult like sepsis. This causes diffuse alveolar
damage, which disrupts the alveolar-capillary membrane and leads to increased
permeability. This results in the leakage of protein-rich fluid into the alveolar spaces,
causing pulmonary edema, impaired gas exchange, and stiff lungs.
Question 6: A child is diagnosed with cystic fibrosis. Which of the following
best describes the underlying genetic defect and its primary physiological
consequence?
A. Mutation in the CFTR gene leading to defective chloride transport and thick, viscous
secretions
B. Deletion of a phenylalanine residue in the alpha-1 antitrypsin protein
C. Autosomal dominant mutation causing abnormal hemoglobin structure
D. Mutation in the gene encoding for dystrophin protein
CORRECT ANSWER: A. Mutation in the CFTR gene leading to defective
chloride transport and thick, viscous secretions
Rationale: Cystic fibrosis is caused by a mutation in the cystic fibrosis transmembrane
conductance regulator (CFTR) gene, most commonly a deletion of phenylalanine at
position 508. This defect impairs chloride transport across epithelial cell membranes,
leading to increased sodium and water absorption. This results in the production of
thick, viscous secretions that obstruct various organ systems, including the lungs,
pancreas, and biliary tract.
Question 7: A 68-year-old male with a 40-pack-year smoking history presents
with a chronic cough, hemoptysis, and weight loss. Imaging reveals a central
mass in his right lung. A biopsy confirms small cell lung cancer (SCLC). Which
of the following paraneoplastic syndromes is most commonly associated with
this type of lung cancer?
A. Hypercalcemia
B. Syndrome of Inappropriate Antidiuretic Hormone (SIADH)
C. Hypertrophic pulmonary osteoarthropathy
D. Gynecomastia

CORRECT ANSWER: B. Syndrome of Inappropriate Antidiuretic Hormone
(SIADH)
Rationale: Small cell lung cancer (SCLC) is a neuroendocrine tumor that is highly
associated with paraneoplastic syndromes. The most common is SIADH, where the
tumor ectopically produces antidiuretic hormone (ADH). This leads to water retention,
hyponatremia, and concentrated urine. SCLC is also associated with Cushing's
syndrome due to ectopic ACTH production.
Question 8: A patient is diagnosed with a deep vein thrombosis (DVT) in the
left leg. A major concern is the risk of a pulmonary embolism (PE). What is the
most direct pathophysiological event leading to PE from a DVT?
A. A piece of the thrombus breaks off and travels through the arterial system to the
lungs
B. The thrombus extends proximally and obstructs the femoral vein
C. A piece of the thrombus embolizes and travels through the venous system to the
pulmonary artery
D. The thrombus causes local inflammation leading to a secondary clot in the
pulmonary vasculature
CORRECT ANSWER: C. A piece of the thrombus embolizes and travels through
the venous system to the pulmonary artery
Rationale: An embolus from a DVT, usually originating in the deep veins of the legs,
travels through the inferior vena cava, into the right atrium, right ventricle, and then
lodges in the pulmonary artery or its branches. This causes a pulmonary embolism,
obstructing pulmonary blood flow and leading to ventilation-perfusion (V/Q) mismatch
and potential right heart strain.
Question 9: A patient with a history of gout presents with an acutely painful,
swollen, and red great toe. Which of the following pathophysiological
processes is the primary cause of this inflammatory response?
A. Deposition of uric acid crystals in the synovial fluid and joint space
B. Autoimmune destruction of the joint cartilage
C. Infection of the joint by Staphylococcus aureus
D. Degeneration of the articular cartilage due to repetitive stress
