Q1.
In a patient with chronic heart failure, which compensatory mechanism is most directly
responsible for the transition from compensated to decompensated state?
A. Sustained activation of the B. Increased sympathetic nervous system
renin-angiotensin-aldosterone system activity causing tachycardia and increased
leading to myocardial fibrosis contractility
C. Ventricular remodeling with eccentric D. Upregulation of beta-adrenergic
hypertrophy and increased wall stress receptors in the myocardium
Correct: A - Sustained activation of the renin-angiotensin-aldosterone system leading to
myocardial fibrosis
Rationale:Chronic RAAS activation promotes fibrosis, sodium retention, and afterload
increase, driving decompensation. Sympathetic activity initially compensates but becomes
maladaptive via receptor downregulation (not upregulation). Remodeling is a consequence,
not the primary trigger.
Q2.
Which combination of findings best distinguishes syndrome of inappropriate antidiuretic
hormone secretion (SIADH) from cerebral salt wasting (CSW)?
A. Plasma osmolality and urine sodium B. Urine osmolality and serum potassium
concentration level
C. Volume status and urine sodium D. Serum sodium level and urine output
concentration
Correct: C - Volume status and urine sodium concentration
Rationale:SIADH is euvolemic or hypervolemic with high urine sodium; CSW is hypovolemic
with high urine sodium. Volume status is key. Plasma/urine osmolality are similar. Potassium
and sodium levels are not distinguishing.

Q3.
A patient with acute respiratory distress syndrome (ARDS) has a PaO2 of 55 mmHg on
100% oxygen. Which finding would most likely explain the refractory hypoxemia?
A. Decreased cardiac output leading to B. Right-to-left intrapulmonary shunting due
reduced mixed venous oxygen content to alveolar flooding
C. Increased dead space ventilation from D. Diffusion limitation due to thickened
pulmonary embolism alveolar-capillary membrane
Correct: B - Right-to-left intrapulmonary shunting due to alveolar flooding
Rationale:ARDS causes severe shunting from alveolar fluid/collapse; 100% O2 cannot
overcome shunted blood. Decreased cardiac output worsens hypoxemia but is not the
primary cause. Diffusion limitation is less prominent. Dead space causes hypercapnia, not
hypoxemia.
Q4.
Which laboratory finding is most consistent with the early proliferative phase of acute
post-streptococcal glomerulonephritis?
A. Decreased serum C3 and C4 levels B. Elevated antinuclear antibody titer
C. Positive cytoplasmic antineutrophil D. Decreased serum albumin and total
cytoplasmic antibody protein
Correct: A - Decreased serum C3 and C4 levels
Rationale:Post-strep GN is immune-complex mediated, consuming complement (low C3/C4).
ANA is for lupus, c-ANCA for vasculitis. Hypoalbuminemia is typical of nephrotic syndrome,
not nephritic.
Q5.
A patient with chronic obstructive pulmonary disease (COPD) develops cor pulmonale.
Which hemodynamic change is the primary driver of right ventricular failure?
A. Decreased pulmonary capillary wedge B. Increased pulmonary vascular resistance
pressure from hypoxic vasoconstriction
C. Decreased right ventricular preload due D. Increased systemic vascular resistance
to hyperinflation from hypercapnia
Correct: B - Increased pulmonary vascular resistance from hypoxic vasoconstriction
Rationale:Chronic hypoxia causes pulmonary vasoconstriction and remodeling, raising PVR
and afterload on the RV. PCWP is normal. Hyperinflation may affect RV filling but is not
primary. Systemic resistance is not directly increased.
