,Q1. A patient with chronic heart failure is started on sacubitril/valsartan. Which
mechanism best explains the combined benefit of this drug in reducing mortality?
A. Inhibition of neprilysin and blockade of AT1 receptors, increasing natriuretic
peptides and reducing aldosterone release.
B. Combined ACE inhibition and angiotensin II receptor blockade, preventing
bradykinin degradation and reducing afterload.
C. Selective aldosterone antagonism with concurrent neprilysin inhibition, reducing
fibrosis and fluid retention.
D. Beta-1 selective blockade with vasodilatory properties, decreasing myocardial
oxygen demand and improving remodeling.
Correct Answer: A. Inhibition of neprilysin and blockade of AT1 receptors,
increasing natriuretic peptides and reducing aldosterone release.
Rationale: Sacubitril/valsartan is a first-in-class ARNI that inhibits neprilysin (increasing
natriuretic peptides) and blocks AT1 receptors (reducing aldosterone and
vasoconstriction). This dual action reduces preload/afterload and maladaptive
remodeling, lowering mortality in HFrEF. Option B incorrectly includes ACE inhibition
(not present); C misidentifies aldosterone antagonism; D describes a beta-blocker.
Why Wrong:
B - Incorrect because sacubitril/valsartan does not inhibit ACE; it combines neprilysin
inhibition with AT1 blockade.
C - Incorrect because it is not an aldosterone antagonist; it works via neprilysin
inhibition and AT1 blockade.
D - Incorrect because it has no beta-blocking activity; it acts through natriuretic
peptide enhancement and AT1 blockade.

Q2. In the pathogenesis of type 2 diabetes mellitus, which molecular alteration most
directly contributes to the failure of beta-cell compensation in the setting of insulin
resistance?
A. Increased amyloid polypeptide (amylin) deposition leading to beta-cell apoptosis.
B. Uncoupling of glucose-sensing from insulin secretion due to GLUT2
downregulation.
C. Chronic oxidative stress causing endoplasmic reticulum stress and beta-cell
dedifferentiation.
D. Autoimmune destruction of beta-cells mediated by cytotoxic T lymphocytes.
Correct Answer: C. Chronic oxidative stress causing endoplasmic reticulum stress
and beta-cell dedifferentiation.
Rationale: Chronic hyperglycemia and lipotoxicity induce oxidative stress and ER stress,
leading to beta-cell dedifferentiation and apoptosis, which underlies progressive beta-cell

, failure in T2DM. Amylin deposition (A) is associated but not the primary direct
mechanism; GLUT2 downregulation (B) is not the main trigger; autoimmune destruction
(D) characterizes T1DM.
Why Wrong:
A - Amylin deposition contributes but is not the most direct cause of beta-cell failure
in T2DM.
B - GLUT2 downregulation is not a primary mechanism; beta-cells can still sense
glucose via other pathways.
D - Autoimmune destruction is the hallmark of type 1 diabetes, not type 2.

for Disease in Adults and Children, 9th Ed., Ch. 20.
Q3. In acute respiratory distress syndrome (ARDS), the refractory hypoxemia is
primarily due to which pathophysiological mechanism?
A. Alveolar dead space expansion from microvascular thrombosis.
B. Right-to-left intrapulmonary shunting from alveolar fluid and collapse.
C. Diffusion impairment from thickened alveolar-capillary membrane.
D. Hypoventilation secondary to decreased central respiratory drive.
Correct Answer: B. Right-to-left intrapulmonary shunting from alveolar fluid and
collapse.
Rationale: ARDS is characterized by protein-rich alveolar edema and alveolar collapse,
causing profound ventilation-perfusion mismatch and true intrapulmonary shunt, which is
refractory to supplemental oxygen. Diffusion impairment (C) contributes but is not the
primary cause of severe hypoxemia; dead space (A) causes hypercapnia; hypoventilation
(D) is not a primary feature.
Why Wrong:
A - Increased dead space causes CO2 retention, not refractory hypoxemia.
C - Diffusion limitation is less significant than shunt in ARDS.
D - ARDS does not typically suppress central respiratory drive.
Reference: McCance, K.L. & Huether, S.E. (2023). Pathophysiology, 9th Ed., Ch. 34.
Q4. A patient with chronic kidney disease (CKD) has a serum calcium of 10.8 mg/dL
and an elevated PTH. Which laboratory finding best explains the persistence of
hypercalcemia despite high PTH?
A. Decreased renal 1-alpha-hydroxylase activity leading to low calcitriol.
B. Increased phosphate retention causing calcium-phosphate product elevation.
C. Skeletal resistance to PTH due to downregulation of PTH receptors.
D. Reduced renal excretion of calcium due to decreased glomerular filtration.
Correct Answer: D. Reduced renal excretion of calcium due to decreased glomerular
