,Q1. A 32-year-old male presents with hypertension and hypokalemia. Lab results
show elevated aldosterone and suppressed renin. Which of the following mechanisms
best explains the paradoxical hypokalemia in this patient?
A. Increased aldosterone enhances potassium secretion in the cortical collecting duct
B. Aldosterone directly inhibits the Na+/K+ ATPase in the distal tubule
C. Hyperaldosteronism causes metabolic acidosis, shifting potassium intracellularly
D. Suppressed renin reduces angiotensin II, decreasing potassium reabsorption
Correct Answer: A. Increased aldosterone enhances potassium secretion in the
cortical collecting duct
Rationale: In primary hyperaldosteronism, excess aldosterone stimulates sodium
reabsorption and potassium secretion in the principal cells of the cortical collecting duct,
leading to hypokalemia. Aldosterone upregulates apical ENaC and basolateral Na+/K+
ATPase, increasing potassium excretion. Aldosterone does not directly inhibit Na+/K+
ATPase; it enhances its activity. Metabolic alkalosis, not acidosis, typically accompanies
hyperaldosteronism and shifts potassium into cells, but the primary mechanism is renal
potassium wasting. Suppressed renin is a consequence, not a cause of the hypokalemia.
Why Wrong:
B - Aldosterone actually upregulates Na+/K+ ATPase, not inhibits it, so this is directly
opposite.
C - Hyperaldosteronism typically causes metabolic alkalosis, not acidosis, and the
potassium shift is not the primary cause of hypokalemia.
D - Suppressed renin is a result of volume expansion, and angiotensin II does not
directly regulate potassium reabsorption in this context.

Q2. In a patient with chronic obstructive pulmonary disease (COPD), which of the
following compensatory mechanisms is most likely to be observed in the renal
system?
A. Increased bicarbonate reabsorption and increased hydrogen ion secretion
B. Decreased bicarbonate reabsorption and increased hydrogen ion secretion
C. Increased bicarbonate excretion and decreased hydrogen ion secretion
D. Decreased bicarbonate reabsorption and decreased hydrogen ion secretion
Correct Answer: A. Increased bicarbonate reabsorption and increased hydrogen ion
secretion
Rationale: COPD causes chronic respiratory acidosis due to CO2 retention. The kidneys
compensate by increasing bicarbonate reabsorption and hydrogen ion secretion, which
raises plasma bicarbonate to buffer the acidosis. This is a classic renal compensation for
respiratory acidosis. Decreased bicarbonate reabsorption or excretion would worsen
acidosis. Decreased hydrogen ion secretion would also fail to compensate.
Page 3
, Why Wrong:
B - Decreased bicarbonate reabsorption would not compensate for acidosis; it would
lose buffer.
C - Increased bicarbonate excretion would lower plasma bicarbonate, worsening
acidosis.
D - Both decreased reabsorption and decreased secretion would fail to correct the
acid-base imbalance.

Q3. During the cardiac cycle, the second heart sound (S2) is produced by which of the
following events?
A. Closure of the atrioventricular valves at the onset of ventricular systole
B. Closure of the semilunar valves at the onset of ventricular diastole
C. Vibration of the chordae tendineae during ventricular contraction
D. Turbulent blood flow during rapid ventricular filling
Correct Answer: B. Closure of the semilunar valves at the onset of ventricular
diastole
Rationale: S2 is produced by the closure of the semilunar valves (aortic and pulmonary) at
the beginning of ventricular diastole, when ventricular pressure falls below arterial
pressure. S1 is due to AV valve closure at the onset of systole. Chordae tendineae vibration
and turbulent filling are not the primary causes of S2.
Why Wrong:
A - Closure of AV valves produces S1, not S2.
C - Chordae tendineae contribute to S1, not S2.
D - Rapid ventricular filling is associated with S3, not S2.

Q4. Which of the following best explains the phenomenon of 'ventilation-perfusion
mismatch' in a patient with a pulmonary embolism?
A. Decreased ventilation in the affected region with preserved perfusion
B. Decreased perfusion in the affected region with preserved ventilation
C. Increased perfusion in the affected region with decreased ventilation
D. Proportional decrease in both ventilation and perfusion in the affected region
Correct Answer: B. Decreased perfusion in the affected region with preserved
ventilation
Rationale: A pulmonary embolism obstructs blood flow to a lung region, creating an area
with normal ventilation but reduced perfusion (high V/Q ratio). This is a classic
ventilation-perfusion mismatch where alveolar dead space increases. Decreased
ventilation with preserved perfusion (low V/Q) occurs in airway obstruction, not
