Which finding is most consistent with AKI progression?

Explanation:
AKI progression is best reflected by an increase in serum creatinine because it directly mirrors the kidneys’ declining filtration ability. As glomerular filtration rate falls, creatinine clearance drops and serum creatinine rises, signaling worsening kidney function. BUN can go up too, but it’s influenced by hydration and protein intake, so it’s less specific for progression. A decreasing white blood cell count or a stable platelet count doesn’t track kidney function itself; those values reflect hematologic or inflammatory status rather than changes in renal filtration. So the key indicator of AKI progression is rising creatinine.
