,Q1 ANALYZE THE ETIOLOGY AND PATHOGENESIS OF MAJOR DISEASES ACROSS ORGAN
SYSTEMS
A patient with chronic heart failure develops worsening dyspnea and orthopnea.
Which pathophysiological mechanism most directly contributes to the pulmonary
edema in this setting?
A. Decreased colloid osmotic pressure due to hypoalbuminemia
B. Increased pulmonary capillary hydrostatic pressure due to elevated left atrial pressure
CORRECT
C. Increased capillary permeability due to systemic inflammatory response
D. Lymphatic obstruction due to interstitial fibrosis
RATIONALE: In left-sided heart failure, reduced cardiac output leads to elevated left atrial
pressure, which is transmitted backward to the pulmonary veins and capillaries, increasing
hydrostatic pressure and causing fluid transudation into the alveoli. Hypoalbuminemia (A) lowers
oncotic pressure but is not the primary mechanism in heart failure. Increased permeability (C) is
typical of ARDS, not cardiogenic edema. Lymphatic obstruction (D) is a chronic contributor but
not the acute precipitant.
Q2 ANALYZE THE ETIOLOGY AND PATHOGENESIS OF MAJOR DISEASES ACROSS ORGAN
SYSTEMS
A researcher is studying a mutation that eliminates the function of the cystic
fibrosis transmembrane conductance regulator (CFTR) protein. Which
downstream effect on airway surface liquid is most directly expected?
A. Increased sodium reabsorption leading to dehydrated mucus
B. Impaired chloride secretion causing reduced water secretion and thick mucus CORRECT
C. Excessive chloride secretion resulting in watery secretions
D. Enhanced bicarbonate secretion leading to alkaline mucus
RATIONALE: CFTR primarily mediates chloride secretion in airway epithelial cells. Loss of
function reduces chloride efflux, which in turn decreases sodium and water secretion (via ENaC
coupling), leading to dehydrated, viscous mucus. Sodium reabsorption is increased secondarily,
but the primary defect is chloride secretion, so B is correct. A describes a secondary effect, not
the direct consequence. C and D are opposite of CFTR function.

,Q3 ANALYZE THE ETIOLOGY AND PATHOGENESIS OF MAJOR DISEASES ACROSS ORGAN
SYSTEMS
In a patient with chronic kidney disease, which combination of laboratory findings
is most consistent with the progression to uremia?
A. Increased GFR, decreased creatinine, normal potassium
B. Decreased GFR, increased creatinine, hyperkalemia, metabolic acidosis CORRECT
C. Increased GFR, increased creatinine, hypokalemia, metabolic alkalosis
D. Decreased GFR, normal creatinine, hypocalcemia, respiratory acidosis
RATIONALE: Progressive CKD leads to nephron loss, causing decreased GFR and accumulation
of creatinine. Hyperkalemia results from decreased excretion, and metabolic acidosis from
reduced ammonia synthesis and bicarbonate reabsorption. Increased GFR (A, C) is not seen in
CKD. Respiratory acidosis (D) is not a primary feature of uremia.
Q4 ANALYZE THE ETIOLOGY AND PATHOGENESIS OF MAJOR DISEASES ACROSS ORGAN
SYSTEMS
A patient with type 1 diabetes mellitus has a HbA1c of 9.2%. Which
pathophysiological process is most likely contributing to the development of
microvascular complications?
A. Increased polyol pathway activity leading to sorbitol accumulation in endothelial cells
CORRECT
B. Decreased advanced glycation end-product (AGE) formation due to hyperglycemia
C. Increased nitric oxide production causing vasodilation and capillary leakage
D. Reduced protein kinase C (PKC) activation in vascular smooth muscle
RATIONALE: Chronic hyperglycemia activates the polyol pathway, converting glucose to sorbitol,
which accumulates in cells and causes osmotic damage, contributing to microvascular
complications. Hyperglycemia increases AGE formation (B), not decreases it. Nitric oxide is
typically decreased, not increased (C), and PKC activation is increased (D), not reduced.

, Q5 ANALYZE THE ETIOLOGY AND PATHOGENESIS OF MAJOR DISEASES ACROSS ORGAN
SYSTEMS
A patient with sepsis develops disseminated intravascular coagulation (DIC).
Which laboratory finding is most consistent with the consumption of coagulation
factors?
A. Elevated fibrinogen level
B. Prolonged prothrombin time (PT) CORRECT
C. Elevated platelet count
D. Decreased D-dimer
RATIONALE: In DIC, widespread clotting consumes platelets and coagulation factors, leading to
prolonged PT and aPTT. Fibrinogen is decreased (A), platelets are decreased (C), and D-dimer is
elevated (D) due to fibrinolysis. PT prolongation reflects factor consumption.
Q6 ANALYZE THE ETIOLOGY AND PATHOGENESIS OF MAJOR DISEASES ACROSS ORGAN
SYSTEMS
A patient with chronic liver disease develops ascites. Which combination of
pathophysiological mechanisms is most responsible for the fluid accumulation?
A. Increased portal hydrostatic pressure and decreased plasma oncotic pressure CORRECT
B. Decreased portal hydrostatic pressure and increased plasma oncotic pressure
C. Increased lymphatic drainage and decreased aldosterone
D. Reduced sodium retention and increased albumin synthesis
RATIONALE: Cirrhosis causes portal hypertension (increased hydrostatic pressure in portal
capillaries) and reduced albumin synthesis (decreased plasma oncotic pressure), both favoring
fluid movement into the peritoneal cavity. Secondary hyperaldosteronism worsens sodium
retention. B, C, and D are opposite or incorrect.
