Final answer:
Call the MET team if there is a decrease in urine production or output. Injury, kidney failure, or loss of kidney function can cause this decrease.
Step-by-step explanation:
Call the MET (Medical Emergency Team) if there is a decrease in urine production or urine output. A decrease in urine production can indicate various conditions such as injury, kidney failure, or loss of kidney function.
Injury is indicated by urine production less than 0.5 ml/kg for 12 hours or creatinine levels 2.0 times higher than normal. Kidney failure is defined as urine output below 0.3 ml/kg for 24 hours or creatinine levels 3.0 times higher than normal. Loss of kidney function can be indicated by persistent acute renal failure or complete loss of kidney function for more than four weeks.
In some cases, a kidney biopsy may be performed to diagnose the cause of acute renal failure and determine the prognosis.
