,Q1. In the context of cellular adaptation, which molecular mechanism best explains
the transition from reversible hypertrophy to irreversible heart failure in chronic
pressure overload?
A. Upregulation of insulin-like growth factor 1 (IGF-1) signaling leading to sustained
protein synthesis
B. Activation of the fetal gene program including increased expression of atrial
natriuretic peptide (ANP)
C. Chronic activation of the calcineurin-NFAT pathway causing myocyte apoptosis and
fibrosis
D. Mitochondrial dysfunction and increased reactive oxygen species (ROS) production
triggering autophagy
Correct Answer: C. Chronic activation of the calcineurin-NFAT pathway causing
myocyte apoptosis and fibrosis
Rationale: The transition to heart failure involves maladaptive signaling pathways.
Chronic calcineurin-NFAT activation promotes myocyte apoptosis and fibrosis, leading to
irreversible remodeling. While IGF-1 and fetal gene program are adaptive initially, they
do not directly cause irreversible failure. Mitochondrial dysfunction contributes but is not
the primary switch.
Why Wrong:
A - IGF-1 signaling is generally adaptive and promotes hypertrophy without directly
causing irreversible failure.
B - Fetal gene program re-expression is an adaptive response, not a cause of
decompensation.
D - Mitochondrial dysfunction is a consequence rather than the primary trigger of the
transition.

Q2. A patient with sepsis develops acute kidney injury (AKI). Which
pathophysiological mechanism is most directly responsible for the early decline in
glomerular filtration rate (GFR)?
A. Tubular obstruction by casts and cellular debris
B. Afferent arteriolar vasoconstriction and reduced renal blood flow
C. Backleak of filtrate through damaged tubular epithelium
D. Increased renal interstitial pressure due to edema
Correct Answer: B. Afferent arteriolar vasoconstriction and reduced renal blood flow
Rationale: In sepsis, systemic vasodilation and release of vasoconstrictors (e.g.,
angiotensin II, norepinephrine) cause afferent arteriolar constriction, reducing renal
blood flow and GFR. Tubular obstruction and backleak occur later in established ATN.
Page 3
, Interstitial edema is a secondary phenomenon.
Why Wrong:
A - Tubular obstruction is a later feature of acute tubular necrosis, not the initial
cause.
C - Backleak occurs after tubular damage has already reduced GFR.
D - Interstitial edema is not the primary mechanism for early GFR decline.

Q3. Which of the following best describes the role of the JAK-STAT pathway in the
pathophysiology of myeloproliferative neoplasms (MPNs) such as polycythemia vera?
A. It mediates the anti-apoptotic effects of thrombopoietin on megakaryocytes.
B. A gain-of-function mutation in JAK2 leads to constitutive activation of downstream
signaling, causing unchecked myeloid proliferation.
C. It suppresses erythropoietin receptor expression, leading to erythrocytosis.
D. It promotes the degradation of tumor suppressor proteins, enhancing leukemic
transformation.
Correct Answer: B. A gain-of-function mutation in JAK2 leads to constitutive
activation of downstream signaling, causing unchecked myeloid proliferation.
Rationale: The JAK2 V617F mutation is found in most MPNs, causing constitutive
activation of JAK-STAT signaling and cytokine-independent proliferation of myeloid
lineages. This is a key molecular mechanism. Other options describe unrelated or
incorrect functions.
Why Wrong:
A - Thrombopoietin signaling is not the central pathway in MPNs.
C - JAK-STAT activation typically increases, not suppresses, erythropoietin receptor
signaling.
D - JAK-STAT does not directly degrade tumor suppressors.

10th Ed., Ch. 13
Q4. A patient with chronic obstructive pulmonary disease (COPD) presents with
increased dyspnea and a widened alveolar-arterial (A-a) gradient. Which mechanism
is the most likely contributor to the widened A-a gradient?
A. Decreased inspired oxygen concentration
B. Ventilation-perfusion (V/Q) mismatch due to emphysematous destruction of alveolar
walls
C. Right-to-left cardiac shunt from patent foramen ovale
D. Hypoventilation leading to increased PaCO2
Correct Answer: B. Ventilation-perfusion (V/Q) mismatch due to emphysematous
