,Q1. A patient with chronic heart failure shows elevated B-type natriuretic peptide
(BNP). Which mechanism primarily explains the release of BNP in this context?
A. Increased atrial pressure leading to atrial natriuretic peptide (ANP) release and
cross-reactivity with BNP assays
B. Ventricular myocyte stretch due to volume overload triggering BNP gene expression
C. Renal hypoperfusion stimulating juxtaglomerular cells to secrete BNP
D. Sympathetic activation causing direct release of BNP from nerve terminals in the
ventricles
Correct Answer: B. Ventricular myocyte stretch due to volume overload triggering
BNP gene expression
Rationale: BNP is synthesized and released primarily by ventricular myocytes in response
to increased wall stress from volume or pressure overload. This reflects the ventricle's
attempt to counteract fluid retention via natriuresis and vasodilation.
Why Wrong:
A - ANP is released from atrial myocytes and does not significantly cross-react with
BNP assays; BNP elevation is specific to ventricular stretch.
C - Renal hypoperfusion triggers renin release, not BNP secretion.
D - BNP is not a neurotransmitter; it is a hormone released from cardiac myocytes, not
sympathetic nerves.

for Disease in Adults and Children, 9th Ed., Ch. 32
Q2. In a patient with sepsis, which of the following best explains the transition from
the hyperdynamic (warm) phase to the hypodynamic (cold) phase of septic shock?
A. Progressive depletion of endogenous catecholamines leading to loss of vascular tone
and cardiac depression
B. Downregulation of nitric oxide synthase and reduced nitric oxide production causing
vasoconstriction
C. Compensatory increase in systemic vascular resistance (SVR) due to activation of
the renin-angiotensin-aldosterone system
D. Myocardial depression mediated by cytokines and reduced effective circulating
volume due to capillary leak
Correct Answer: D. Myocardial depression mediated by cytokines and reduced
effective circulating volume due to capillary leak
Rationale: In septic shock, the cold phase results from myocardial depression (due to
cytokines like TNF- and IL-1) and profound hypovolemia from capillary endothelial injury
and fluid extravasation. This leads to decreased cardiac output and vasoconstriction.
Why Wrong:
A - Catecholamine depletion is not the primary cause; the transition is due to
Page 3
, myocardial dysfunction and hypovolemia.
B - Nitric oxide production is increased, not decreased, in sepsis, contributing to
vasodilation.
C - While RAAS is activated, SVR is initially low; the cold phase is characterized by
high SVR but the cause is not compensatory RAAS activation.
Reference: McCance, K.L. & Huether, S.E. (2023). Pathophysiology, 9th Ed., Ch. 23
Q3. Which molecular mechanism is primarily responsible for the resistance of cancer
cells to apoptosis induced by DNA-damaging chemotherapy?
A. Overexpression of Bcl-2, which inhibits the intrinsic mitochondrial pathway
B. Increased activity of caspases, promoting apoptosis
C. Upregulation of p53, enhancing DNA repair
D. Activation of the extrinsic death receptor pathway via Fas ligand
Correct Answer: A. Overexpression of Bcl-2, which inhibits the intrinsic
mitochondrial pathway
Rationale: Bcl-2 is an anti-apoptotic protein that prevents cytochrome c release from
mitochondria, thereby blocking the intrinsic pathway. Many cancers overexpress Bcl-2,
making them resistant to chemotherapy-induced apoptosis.
Why Wrong:
B - Increased caspase activity would promote apoptosis, not resistance.
C - p53 is a tumor suppressor that promotes apoptosis; its upregulation would
sensitize cells to apoptosis.
D - Activation of the extrinsic pathway would induce apoptosis, not resistance.

Basis of Disease, 10th Ed., Ch. 7
Q4. A researcher is studying a novel drug that inhibits the NLRP3 inflammasome.
Which downstream effect is most likely to be observed?
A. Reduced activation of caspase-1 and decreased IL-1 and IL-18 maturation
B. Increased production of type I interferons
C. Enhanced NF-B nuclear translocation and pro-inflammatory cytokine gene
transcription
D. Inhibition of the complement cascade, preventing opsonization
Correct Answer: A. Reduced activation of caspase-1 and decreased IL-1 and IL-18
maturation
Rationale: The NLRP3 inflammasome is a multiprotein complex that activates caspase-1,
which cleaves pro-IL-1 and pro-IL-18 into their active forms. Inhibiting it reduces these
cytokines.
