,Section A - Cellular Adaptation Injury AND Death
Q1.
Which of the following best explains the paradoxical hypoxia observed in septic shock
despite increased cardiac output?
A. Pulmonary vasoconstriction leading to B. Impaired oxygen extraction due to
ventilation-perfusion mismatch mitochondrial dysfunction and microvascular
shunting
C. Reduced oxygen-carrying capacity from D. Anemia caused by hemolysis from
hemodilution disseminated intravascular coagulation
Correct: B - Impaired oxygen extraction due to mitochondrial dysfunction and
microvascular shunting
Rationale:In septic shock, despite hyperdynamic circulation, cells cannot utilize oxygen due
to mitochondrial dysfunction and microvascular shunting that bypasses tissues. Pulmonary
vasoconstriction is not typical; rather, vasodilation occurs. Hemodilution and anemia may
contribute but do not explain the inability to extract oxygen.
Q2.
A patient with chronic kidney disease (stage 4) develops hyperkalemia. Which of the
following best explains the underlying mechanism?
A. Decreased aldosterone secretion due to B. Increased potassium intake from dietary
renin-angiotensin axis suppression sources
C. Reduced distal nephron flow and sodium D. Enhanced potassium reabsorption in the
delivery impairing potassium secretion proximal tubule
Correct: C - Reduced distal nephron flow and sodium delivery impairing potassium
secretion
Rationale:In chronic kidney disease, the reduced number of functioning nephrons leads to
decreased distal flow and sodium delivery, limiting potassium secretion in the collecting duct.
Aldosterone levels may be normal or elevated, not suppressed. Dietary intake is not the
primary mechanism, and proximal tubule reabsorption of potassium is minimal.
Q3.
Which of the following pathological findings is most consistent with the acute phase of
respiratory distress syndrome (ARDS)?
A. Hyaline membranes lining the alveolar B. Pulmonary fibrosis with honeycombing
walls
Page 3
, Section A - Cellular Adaptation Injury AND Death
C. Emphysematous changes with bullae D. Granulomatous inflammation with
caseation
Correct: A - Hyaline membranes lining the alveolar walls
Rationale:The acute exudative phase of ARDS is characterized by hyaline membranes,
alveolar edema, and hemorrhage. Fibrosis with honeycombing is seen in the chronic phase.
Emphysema and granulomas are features of other diseases, not ARDS.
Q4.
In a patient with type 2 diabetes, which of the following best explains the development of
insulin resistance at the cellular level?
A. Downregulation of insulin receptors due B. Increased glucagon secretion from
to chronic hyperinsulinemia pancreatic alpha cells
C. Autoimmune destruction of pancreatic D. Deficiency of insulin receptor substrate-1
beta cells (IRS-1) signaling
Correct: D - Deficiency of insulin receptor substrate-1 (IRS-1) signaling
Rationale:Insulin resistance involves impaired insulin receptor signaling, including reduced
IRS-1 phosphorylation and downstream PI3K activation. Downregulation of receptors occurs
but is not the primary mechanism. Glucagon excess contributes to hyperglycemia but not
peripheral resistance. Autoimmune destruction causes type 1 diabetes.
Q5.
Which of the following pathophysiological mechanisms is most directly responsible for
the clinical features of Parkinson's disease?
A. Loss of dopaminergic neurons in the B. Accumulation of beta-amyloid plaques in
substantia nigra pars compacta the cerebral cortex
C. Demyelination of the corticospinal tract D. Reduced gamma-aminobutyric acid
(GABA) in the basal ganglia
Correct: A - Loss of dopaminergic neurons in the substantia nigra pars compacta
Rationale:Parkinson's disease is primarily caused by degeneration of dopaminergic neurons
in the substantia nigra, leading to reduced dopamine in the striatum. Beta-amyloid plaques
are seen in Alzheimer's, demyelination in multiple sclerosis, and GABA changes are
secondary.
Q6.
A patient with severe asthma exacerbation has a PaCO2 of 55 mmHg. Which of the
following best explains this finding?
