Question 4

Estimated glomerular filtration rate 30-60 mL/min is the first criteria for referring patients to nephrologists for chronic kidney disease (CKD) management.

Referring patients to nephrologists for chronic kidney disease management is typically based on an estimated glomerular filtration rate (eGFR) of 30-60 mL/min, as this range indicates a moderate reduction in kidney function that requires specialized care.

A) Estimated glomerular filtration rate 120 mL/min

This option reflects normal kidney function and does not indicate a need for nephrology referral. An eGFR of 120 mL/min suggests that the kidneys are functioning well, thus it is not a criterion for CKD management referral.

B) Estimated glomerular filtration rate 30 mL/min

While an eGFR of 30 mL/min denotes severe kidney impairment, it is not the primary threshold for referral. Patients with this level of kidney function are often already considered for nephrology care; however, the more commonly accepted range to initiate referral is 30-60 mL/min.

C) Estimated glomerular filtration rate 30-60 mL/min

This option is correct as it represents the criteria for referring patients to nephrologists for chronic kidney disease management. An eGFR within this range indicates a moderate decline in kidney function, warranting specialized evaluation and management.

D) Estimated glomerular filtration rate >90 mL/min

An eGFR greater than 90 mL/min indicates normal kidney function and does not necessitate a referral to nephrology. Patients in this category typically do not require specialized kidney management.

Conclusion

The correct answer is C, as an estimated glomerular filtration rate of 30-60 mL/min is the recognized criteria for initiating referral to nephrologists for chronic kidney disease management. Options A, B, and D either indicate normal kidney function or do not encapsulate the threshold for referral, thus failing to meet the criteria necessary for specialized care.
