,Q1. A patient with chronic hypertension develops progressive renal dysfunction.
Which pathophysiological mechanism is most directly responsible for glomerular
injury in this setting?
A. Increased glomerular capillary hydrostatic pressure leading to mesangial cell stretch
and matrix expansion
B. Activation of the renin-angiotensin-aldosterone system causing efferent arteriole
dilation
C. Autoimmune deposition of immune complexes in the glomerular basement
membrane
D. Ischemic injury to tubular epithelial cells due to reduced renal blood flow
Correct Answer: A. Increased glomerular capillary hydrostatic pressure leading to
mesangial cell stretch and matrix expansion
Rationale: Chronic hypertension transmits elevated systemic pressure to glomerular
capillaries, causing glomerular hypertension. This mechanically stresses mesangial cells,
promoting matrix expansion and sclerosis. RAAS activation actually constricts efferent
arterioles, not dilates. Immune complex deposition is more typical of glomerulonephritis,
and tubular ischemia is secondary.
Why Wrong:
B - RAAS activation causes efferent arteriole constriction (not dilation), and while it
contributes, the primary injury is hemodynamic.
C - Immune complex deposition is characteristic of immune-mediated
glomerulonephritis, not hypertensive nephrosclerosis.
D - Ischemic tubular injury is a consequence of advanced disease, not the primary
mechanism of glomerular damage.

Q2. In a patient with type 2 diabetes, which molecular alteration in the insulin
signaling pathway most directly contributes to insulin resistance?
A. Increased phosphorylation of IRS-1 on serine residues
B. Enhanced tyrosine kinase activity of the insulin receptor
C. Upregulation of GLUT4 translocation to the plasma membrane
D. Overexpression of insulin receptor substrate-2 (IRS-2)
Correct Answer: A. Increased phosphorylation of IRS-1 on serine residues
Rationale: Serine phosphorylation of IRS-1 (by kinases like JNK or PKC) inhibits its
ability to engage PI3K, impairing downstream signaling and GLUT4 translocation.
Enhanced tyrosine kinase activity and GLUT4 upregulation would improve sensitivity.
IRS-2 overexpression is compensatory, not a cause of resistance.
Why Wrong:
B - Enhanced tyrosine kinase activity would increase insulin signaling, not cause
Page 3
, resistance.
C - Upregulation of GLUT4 would enhance glucose uptake, improving sensitivity.
D - IRS-2 overexpression is a compensatory mechanism, not a primary cause of
resistance.

for Disease in Adults and Children, 9th Ed., Ch. 21
Q3. Which of the following best explains the phenomenon of referred pain in
myocardial ischemia?
A. Convergence of visceral and somatic afferent fibers on the same spinal cord neurons
B. Direct spread of ischemic mediators through the pericardium to adjacent somatic
structures
C. Activation of sympathetic efferent fibers that sensitize somatic nociceptors
D. Irradiation of action potentials from the heart to the skin via electrical synapses
Correct Answer: A. Convergence of visceral and somatic afferent fibers on the same
spinal cord neurons
Rationale: Referred pain arises because visceral afferents from the heart converge on the
same dorsal horn neurons that receive somatic input from the arm or jaw. The brain
misinterprets the origin. Ischemic mediators do not spread directly, sympathetic efferents
are not involved in sensation, and electrical synapses are not implicated.
Why Wrong:
B - Mediators do not physically spread; convergence is the established mechanism.
C - Sympathetic efferents are motor, not sensory, and do not sensitize somatic
nociceptors.
D - Action potentials do not jump via electrical synapses in this context.
Reference: McCance & Huether (2026), Ch. 5
Q4. In the pathogenesis of asthma, which inflammatory mediator is most directly
responsible for bronchial hyperresponsiveness and airway remodeling?
A. Leukotriene D4
B. Histamine
C. Interleukin-5
D. Interleukin-13
Correct Answer: D. Interleukin-13
Rationale: IL-13 drives key features of asthma: goblet cell metaplasia, subepithelial
fibrosis, and smooth muscle hyperplasia, contributing to remodeling and
hyperresponsiveness. LTD4 and histamine cause acute bronchoconstriction. IL-5 mainly
promotes eosinophil survival and recruitment.
