Sample item

Which urine output criterion contributes to the KDIGO definition of acute kidney injury in a critically ill adult?

ALess than 0.5 mL/kg/h for 6 hours or moreBLess than 2 mL/kg/h for 12 hoursCLess than 0.5 mL/kg/h for 1 hourDLess than 1 mL/kg/h for 6 hours

Original practice item, not a recalled exam question. Nothing here is recorded.

The answer and the reasoning

A. Less than 0.5 mL/kg/h for 6 hours or more

KDIGO defines acute kidney injury by a creatinine rise of 0.3 mg/dL within 48 hours, a rise of at least 1.5 times baseline within 7 days, or a urine output below 0.5 mL/kg/h for 6 hours. A single hour of low output is too short and is common during anaesthesia.

Option by option

A. Less than 0.5 mL/kg/h for 6 hours or more (correct)
Correct. Sustained oliguria for 6 hours meets the urine criterion.
B. Less than 2 mL/kg/h for 12 hours
A threshold of 2 mL/kg/h is far above the oliguria range.
C. Less than 0.5 mL/kg/h for 1 hour
One hour of low output is too brief to define injury.
D. Less than 1 mL/kg/h for 6 hours
A threshold of 1 mL/kg/h is higher than the KDIGO value.

A threshold of 2 mL/kg/h is far above the oliguria range.

Why is "Less than 0.5 mL/kg/h for 1 hour" not the answer?

One hour of low output is too brief to define injury.

Why is "Less than 1 mL/kg/h for 6 hours" not the answer?

A threshold of 1 mL/kg/h is higher than the KDIGO value.

What concept does this question test?

It tests Critical care, resuscitation, and emergency principles: curriculum recognition in Anaesthesia. 3 mg/dL within 48 hours, a rise of at least 1.5 times baseline within 7 days, or a urine output below 0.5 mL/kg/h for 6 hours. A single hour of low output is too short and is common during anaesthesia.
