What GFR value is expected in a patient classified in stage 2 kidney disease?

In stage 2 chronic kidney disease (CKD), the glomerular filtration rate (GFR) is typically between 60 and 89 mL/min/1.73m². This stage is characterized by mild kidney damage, and while kidney function is reduced, it is not severely impaired.

The value of 70 mL/min/1.73m² falls within this range and reflects a moderate decrease in kidney function, consistent with the classification of stage 2 CKD. Patients at this stage often have few or no symptoms, and kidney function can remain stable for some time, allowing for monitoring and management before progressing to more severe stages.

In contrast, other GFR values presented in the options either indicate more advanced stages of kidney disease or are too high to represent the expected decline seen in stage 2. Thus, choosing a GFR of 70 mL/min/1.73m² aligns with the clinical understanding of stage 2 kidney disease.
