Q1.
Which pathophysiological mechanism best explains the development of diuretic
resistance in a patient with chronic heart failure who is receiving high-dose loop
diuretics?
A. Downregulation of B. Compensatory hypertrophy of distal
sodium-potassium-chloride cotransporters in nephron segments leading to increased
the thick ascending limb sodium reabsorption
C. Decreased renal blood flow due to D. Increased aldosterone levels causing
reduced cardiac output enhanced sodium reabsorption in the
collecting duct
Correct: B - Compensatory hypertrophy of distal nephron segments leading to increased
sodium reabsorption
Rationale:Chronic loop diuretic use enhances distal tubular sodium reabsorption, a
phenomenon known as 'diuretic braking,' which limits the diuretic response. Distal tubular
hypertrophy increases the reabsorptive capacity, counteracting the effects of loop diuretics.
While reduced renal blood flow and hyperaldosteronism contribute to diuretic resistance, the
primary adaptation is hypertrophy of distal segments.
Q2.
A patient with type 2 diabetes and chronic kidney disease (eGFR 32 mL/min/1.73m²) is
being started on an SGLT2 inhibitor. Which statement best reflects the current
evidence-based recommendation?
A. SGLT2 inhibitors are contraindicated at B. SGLT2 inhibitors are recommended to
this eGFR due to lack of glucose-lowering slow CKD progression, regardless of
efficacy. glycemic control.
C. SGLT2 inhibitors should be avoided D. SGLT2 inhibitors are safe but require
because they increase the risk of acute dose adjustment based on baseline eGFR.
kidney injury.
Correct: B - SGLT2 inhibitors are recommended to slow CKD progression, regardless of
glycemic control.
Rationale:Current KDIGO guidelines recommend SGLT2 inhibitors for patients with CKD and
eGFR 25 mL/min/1.73m² (or 20 in some regions) to reduce the risk of CKD progression and
cardiovascular events, independent of diabetes status. Their efficacy is not solely dependent
on glycemic control, and they are not contraindicated at this eGFR. Dose adjustment is not
typically required for this class.

Q3.
Which of the following findings is most consistent with a diagnosis of primary
hyperaldosteronism rather than essential hypertension?
A. Plasma renin activity is suppressed and B. Plasma renin activity is elevated and
plasma aldosterone concentration is plasma aldosterone concentration is low
elevated
C. Plasma renin activity is normal and D. Plasma renin activity is elevated and
plasma aldosterone concentration is normal plasma aldosterone concentration is
elevated
Correct: A - Plasma renin activity is suppressed and plasma aldosterone concentration is
elevated
Rationale:Primary hyperaldosteronism is characterized by autonomous aldosterone
secretion, leading to sodium retention and hypertension while suppressing renin. Thus, the
hallmark is a low renin and high aldosterone. Elevated renin with low aldosterone suggests
secondary hyperaldosteronism (e.g., renal artery stenosis). Normal levels are not consistent
with the diagnosis.
Q4.
A patient with severe sepsis is receiving norepinephrine but remains hypotensive. Which
hemodynamic parameter would best indicate the need for adding vasopressin rather than
increasing norepinephrine further?
A. Cardiac index of 2.2 L/min/m² B. Central venous pressure of 8 mmHg
C. Mean arterial pressure of 62 mmHg D. Mixed venous oxygen saturation of 70%
despite norepinephrine at 0.5 mcg/kg/min
Correct: C - Mean arterial pressure of 62 mmHg despite norepinephrine at 0.5 mcg/kg/min
Rationale:The Surviving Sepsis Campaign recommends adding vasopressin when the
norepinephrine dose exceeds 0.25-0.5 mcg/kg/min to achieve target MAP, rather than
escalating norepinephrine further, due to diminishing returns and increased adverse effects.
The other parameters do not specifically indicate the need for a second vasopressor.
Q5.
Which pharmacokinetic change in elderly patients most significantly increases the risk of
toxicity from drugs that undergo hepatic metabolism via CYP450?
A. Increased hepatic blood flow B. Reduced first-pass metabolism
C. Decreased renal excretion D. Increased volume of distribution for
lipophilic drugs
