Q1.
A patient with chronic kidney disease has an arterial blood gas: pH 7.28, PaCO 30 mm Hg,
HCO 14 mEq/L. Which compensatory mechanism is primarily responsible for the PaCO
value?
A. Increased renal reabsorption of B. Hyperventilation via chemoreceptor
bicarbonate stimulation
C. Hypoventilation due to respiratory muscle D. Increased production of carbonic acid
fatigue
Correct: B - Hyperventilation via chemoreceptor stimulation
Rationale:The low pH with low HCO ƒ { indicates metabolic acidosis; the low PaCO ‚ reflects
respiratory compensation via hyperventilation triggered by chemoreceptors. Renal
compensation (A) would raise HCO but is slow and not the cause of the low PaCO.
Hypoventilation (C) would raise PaCO, and increased carbonic acid (D) would worsen
acidosis.
Q2.
Which molecular event best explains the irreversible cell injury seen in
ischemia-reperfusion injury?
A. ATP depletion causing failure of the B. Generation of reactive oxygen species
Na/K-ATPase pump and mitochondrial permeability transition
C. Influx of calcium leading to activation of D. Anaerobic glycolysis producing lactic acid
proteases and phospholipases and intracellular acidosis
Correct: B - Generation of reactive oxygen species and mitochondrial permeability
transition
Rationale:Reperfusion injury is characterized by a burst of reactive oxygen species and
opening of the mitochondrial permeability transition pore, which triggers apoptosis and
necrosis. ATP depletion (A) and calcium influx (C) occur in ischemia but are not specific to
reperfusion. Lactic acidosis (D) contributes to injury but is not the primary irreversible
mechanism upon reperfusion.

Q3.
A patient with sepsis has a lactate level of 4.2 mmol/L and a central venous oxygen
saturation (ScvO) of 58%. Which pathophysiologic process is most consistent with these
findings?
A. Increased oxygen delivery with impaired B. Impaired oxygen utilization due to
extraction mitochondrial dysfunction
C. Adequate tissue perfusion with anaerobic D. Reduced cardiac output with
metabolism compensatory vasoconstriction
Correct: B - Impaired oxygen utilization due to mitochondrial dysfunction
Rationale:In septic shock, mitochondrial dysfunction impairs oxygen utilization despite
adequate delivery, leading to low ScvO and elevated lactate. Option A would show high
ScvO. Option C is incorrect because elevated lactate indicates anaerobic metabolism. Option
D may occur but does not directly explain the low ScvO and high lactate.
Q4.
Which statement accurately distinguishes apoptosis from necrosis in the context of
cellular injury?
A. Apoptosis is an energy-dependent, B. Necrosis is a regulated process that
programmed process that avoids requires caspase activation.
inflammation.
C. Apoptosis typically triggers a robust D. Necrosis is always reversible if the
inflammatory response due to cell lysis. injurious stimulus is removed.
Correct: A - Apoptosis is an energy-dependent, programmed process that avoids
inflammation.
Rationale:Apoptosis is an active, ATP-dependent form of programmed cell death that does
not incite inflammation. Necrosis (B) is generally unregulated and does not require caspases.
Apoptosis (C) does not cause inflammation because the membrane remains intact. Necrosis
(D) is often irreversible once membrane integrity is lost.
Q5.
A patient with a history of myocardial infarction develops a new-onset third heart sound
(S3) and jugular venous distension. Which pathophysiologic mechanism best explains
these findings?
A. Reduced left ventricular compliance B. Increased left ventricular afterload
causing pulmonary congestion leading to hypertrophy
C. Volume overload and decreased left D. Impaired right ventricular emptying due to
ventricular ejection fraction pulmonary hypertension
