Which statement best reflects understanding of renal replacement therapy in CKD?

• A. Dialysis cures CKD completely
• B. CKD is fatal unless a transplant is done
• C. Dialysis is optional and rarely used
• D. Renal replacement therapy will need to be initiated immediately to rid the body of waste and maintain fluid balance

Answer: (D)

Renal replacement therapy is used when the kidneys can no longer keep waste products, fluids, and electrolytes in balance. It doesn’t cure CKD; it substitutes kidney function to keep the body steady while kidney disease progresses or until a transplant can be considered. The goal is to remove waste, correct electrolyte disturbances, and control fluid balance, which are essential for life when kidney function is severely impaired. The timing of starting replacement therapy depends on clinical signs and lab findings such as rising waste products, electrolyte abnormalities, acidosis, and fluid overload—not every patient needs it immediately, but it becomes necessary as kidney function declines and symptoms or risks become unmanageable. The other statements misstate the role: dialysis is not a cure, CKD isn’t universally fatal without a transplant, and dialysis is not merely optional or rarely used.
