Which GFR range defines stage 2 kidney damage?

• A. >90
• B. 60-80
• C. 30-59
• D. 15-20

Answer: (B)

Stage 2 reflects a mild decline in kidney filtration accompanied by evidence of kidney damage. In this stage, the GFR is not normal, but it isn’t severely reduced, and kidney damage markers (like protein in the urine or structural changes) are present. Among the options, the middle range best represents this mild decrease with damage. The higher range would indicate near-normal function with damage (Stage 1), while the lower ranges indicate progressively more severe impairment (Stages 3–5). So the middle option matches the concept of Stage 2 kidney damage.
