QuestionChoice
This is incorrect. The GFR is calculated by multiplying the urine:plasma creatinine ratio by the rate of urine output in 24 hours. In this case, it is 6000/60 x 1.9/24 = 7.9 L/hour.

A man with a plasma creatinine concentration of 60 μmol/L (normal range 60-120μmol/L) undergoes a 24-hour urine collection. During the 24 hours, 1.9L of urine is collected with a urinary creatinine concentration of 6000 micromoles/L (normal ranges: (F) 6 - 13 (M) 9 - 19).

What is the man's GFR in L/hour?
