Q1.
A patient with prolonged ischemia to the myocardium has a serum troponin that is rising,
a lactate that is rising, and a new rise in intracellular enzymes. Which mechanism best
explains the shift from reversible to irreversible injury?
A. ATP depletion causing failure of the B. Increased lysosomal enzyme release into
Na+/K+ ATPase and calcium influx the cytosol with membrane digestion
C. Reperfusion-induced free radical D. Activation of caspase-9 and the intrinsic
generation and mitochondrial permeability apoptotic pathway
transition pore opening
Correct: C - Reperfusion-induced free radical generation and mitochondrial permeability
transition pore opening
Rationale:Irreversible injury after reperfusion is driven by reactive oxygen species and
opening of the mitochondrial permeability transition pore, which collapses ATP production and
commits the cell to death. ATP depletion and calcium influx initiate injury but are still
potentially reversible. Lysosomal release and caspase-9 activation occur downstream or in
apoptosis, not as the primary switch to irreversibility.
Q2.
A patient with a deep partial-thickness burn has a wound culture positive for
Pseudomonas aeruginosa and a white blood cell count of 18,000/mm3. Which finding
indicates the wound has progressed from inflammation to infection?
A. Presence of granulation tissue at the B. Purulent exudate with a foul odor and
wound margins surrounding induration
C. Mild erythema limited to the wound edges D. Serous drainage with a small amount of
slough
Correct: B - Purulent exudate with a foul odor and surrounding induration
Rationale:Purulent exudate, foul odor, and surrounding induration are classic signs of
bacterial invasion and tissue destruction, indicating infection rather than simple inflammation.
Granulation tissue, mild erythema, and serous drainage are expected inflammatory or healing
findings. The elevated white count supports but does not alone define local infection.

Q3.
Which statement best distinguishes the pathophysiology of type I from type II
hypersensitivity reactions?
A. Type I is IgG-mediated and type II is B. Type I involves IgE and mast cell
IgE-mediated degranulation; type II involves IgG or IgM
binding to fixed antigens
C. Type I is delayed and cell-mediated; type D. Type I requires complement; type II is
II is immediate and mediated by T lymphocytes
complement-independent
Correct: B - Type I involves IgE and mast cell degranulation; type II involves IgG or IgM
binding to fixed antigens
Rationale:Type I hypersensitivity is IgE-mediated with mast cell degranulation and immediate
mediator release, while type II is antibody (IgG or IgM) mediated against antigens on cell
surfaces or matrix. Type I is not IgG-mediated and type II is not IgE-mediated. Delayed
cell-mediated responses define type IV, not type I, and type II can activate complement.
Q4.
A patient with disseminated intravascular coagulation (DIC) has a platelet count of
40,000/mm3, a prolonged PT and aPTT, a fibrinogen of 90 mg/dL, and a D-dimer of 8.0
mcg/mL. Which pathophysiologic process best explains these results?
A. Primary fibrinolysis without thrombin B. Widespread activation of coagulation with
generation consumption of platelets and clotting factors
and secondary fibrinolysis
C. Isolated platelet destruction from immune D. Vitamin K deficiency causing reduced
thrombocytopenia synthesis of factors II, VII, IX, and X
Correct: B - Widespread activation of coagulation with consumption of platelets and
clotting factors and secondary fibrinolysis
Rationale:DIC is characterized by systemic activation of coagulation, consumption of
platelets and factors, and secondary fibrinolysis, which explains the low platelets, prolonged
PT/aPTT, low fibrinogen, and elevated D-dimer. Primary fibrinolysis does not cause thrombin
generation and factor consumption. Immune thrombocytopenia and vitamin K deficiency do
not produce the full constellation of low fibrinogen and elevated D-dimer.
Q5.
A patient with syndrome of inappropriate antidiuretic hormone (SIADH) has a serum
sodium of 122 mEq/L, serum osmolality of 260 mOsm/kg, and urine osmolality of 600
mOsm/kg. Which intervention is most appropriate initially?
