QuestionChoice
This is the correct answer. Chronic kidney disease is defined as abnormalities in kidney function or structure for at least 3 months. The KDIGO guidelines classify the severity and progression of chronic kidney disease based on the level of persistent albuminuria and the Glomerular Filtration Rate (GFR). In this case, an eGFR of 20ml/min/1.73m^2 puts the patient in the category of stage 4, which ranges from 15-29ml/min/1.73m^2 and indicates severely decreased kidney function

a
Stage 4
QuestionChoice
This is not the correct answer. In stage 3b, the GFR ranges from 45-59ml/min/1.73m^2, which implies mild to moderately decreased kidney function.

c
Stage 3b
QuestionChoice
This is not the correct answer. In stage 1, the GFR range is 90ml/min/1.73m^2 and above, which implies normal or high kidney function.
