A) Stage 1
B) Stage 2
C) Stage 3
D) Stage 4
Ans: C
Feedback: Stages of chronic renal failure are based on the glomerular filtration rate (GFR).
Stage 3 is defined by a GFR in the range of 30–59 mL/min/1.73 m2. This is considered a moderate decrease in GFR. Stage 1 is defined by a GFR ? 90 mL/min/1.73 m2. Stage 2 is defined by a GFR of 60–89 mL/min/1.73 m2. Stage 4 is a GFR in the range of 15–29 mL/min/1.73 m2. Stage 5 is a GFR > 15 mL/min/1.73 m2. Therefore options A, B, and D are incorrect.
