01
Front

What creatinine rise within 48 hours meets an AKI criterion?

Back

Yes. A serum creatinine rise of at least 0.3 mg/dL0.3\ \text{mg/dL} within 4848 hours meets an AKI criterion, even if urine output is unchanged.

02
Front

What defines prerenal AKI?

Back

Prerenal AKI results from inadequate kidney perfusion.

03
Front

What creatinine range defines KDIGO AKI Stage 2?

Back

Stage 2 includes a serum creatinine rise to 2.02.0–2.9×2.9\times baseline.

04
Front

What if creatinine and urine output indicate different AKI stages?

Back

When creatinine and urine-output criteria indicate different stages, use the more severe stage.

05
Front

What urine-output threshold and duration define Stage 2?

Back

Stage 2 by urine output is below 0.5 mL kg−1 hour−10.5\ \text{mL}\,\text{kg}^{-1}\,\text{hour}^{-1} for at least 1212 hours.

06
Front

What assessments help investigate AKI and monitor the patient?

Back

Review intake and output, weight, and volume status; review medicines and exposures; perform urinalysis; and assess for obstruction when indicated.

07
Front

Should electrolyte monitoring stop once AKI is diagnosed?

Back

Continue monitoring electrolytes and other complications after AKI is diagnosed; diagnosis is not a reason to stop monitoring.

08
Front

How should suspected volume depletion in AKI be managed?

Back

For volume depletion, assess and restore circulating volume with appropriate fluids, monitor response and fluid overload, and address the fluid loss. Treatment depends on the patient’s condition.

09
Front

Name practical steps to reduce AKI risk in hospitalized patients.

Back

Reduce risk through early monitoring of creatinine and urine output, treatment of dehydration or infection, review of potentially harmful medicines, and dose adjustment when kidney function is impaired.

10
Front

What creatinine change within 7 days meets an AKI criterion?

Back

A rise to at least 1.5×1.5\times baseline within 77 days meets a serum creatinine criterion for AKI.

11
Front

What urine output and duration meet an AKI criterion?

Back

Urine output below 0.5 mL kg−1 hour−10.5\ \text{mL}\,\text{kg}^{-1}\,\text{hour}^{-1} for at least 66 hours meets a urine-output criterion for AKI.

12
Front

What defines intrinsic renal AKI?

Back

Intrinsic renal AKI involves injury within the kidneys; acute glomerulonephritis is an example.
