ascites. Which physiologic alteration is most directly responsible for the
reduced movement of water into the vascular compartment?
A. Increased plasma albumin concentration
B. Reduced plasma oncotic pressure caused by impaired protein synthesis
C. Increased renal sodium excretion
D. Reduced portal venous pressure
Answer: B
pg. 3
, 10. A 72-year-old patient with a history of atrial fibrillation suddenly develops
aphasia and right-sided weakness. Imaging confirms an ischemic cerebral
infarction. Which mechanism most likely initiated the neuronal injury?
A. Increased cerebral oxygen delivery
B. Excessive glucose availability to neurons
C. Increased ATP production by ischemic neurons
D. Loss of oxidative phosphorylation with cellular energy depletion
Answer: D
11. A patient develops severe tissue injury after prolonged ischemia followed
by restoration of blood flow. The injury is more extensive than expected
from ischemia alone. Which mechanism best explains this phenomenon?
A. Reperfusion-associated generation of reactive oxygen species
B. Complete inhibition of inflammatory leukocyte activity
C. Permanent reduction in mitochondrial oxygen consumption
D. Decreased intracellular calcium accumulation during reperfusion
Answer: A

dietary iron intake. Laboratory findings demonstrate decreased serum iron
and increased ferritin. Which mechanism best explains the anemia?
A. Increased intestinal iron absorption caused by elevated hepcidin
B. Excessive erythrocyte production caused by chronic inflammation
C. Hepcidin-mediated sequestration of iron within storage cells
D. Increased renal erythropoietin secretion caused by inflammation
