Your answer:
Urine output
Blood urea
Calculated eGFR
AKI stages per KDIGO (2012)
Diagnosis: creatinine rise ≥0.3 mg/dL within 48 hours, or ≥1.5× baseline within 7 days, or urine output <0.5 mL/kg/h for 6 hours.
Stage 1: ≥0.3 mg/dL or 1.5–1.9× baseline, or urine output <0.5 mL/kg/h for 6–12 hours.
Stage 2: 2.0–2.9× baseline, or urine output <0.5 mL/kg/h for ≥12 hours.
Stage 3: ≥3.0× baseline, or creatinine ≥4.0 mg/dL, or initiation of dialysis, or urine output <0.3 mL/kg/h for ≥24 hours, or anuria ≥12 hours.
In this case: a difference of 0.27 mg/dL (under 0.3) and a ratio of 1.18× (under 1.5) — neither creatinine threshold was crossed. Urine output was never given, and without it AKI cannot be ruled out with confidence.

COMPARISON

Not a question bank. Not a general AI tool.

A question bank gives you practice with no guidance. A general AI tool gives you guidance — but only once you've gathered every source yourself and fed it the context. MeduXa comes pre-built around the board exam, with both already in place.
