Which statement best describes the purpose of hemodialysis in end-stage renal disease?

• A. It removes waste and excess fluids from the blood.
• B. It cures kidney disease completely.
• C. It eliminates the need for any other therapy.
• D. It replaces the kidney permanently with a donor organ.

Answer: (A)

Hemodialysis is used to remove waste products and excess fluids from the blood when the kidneys can no longer perform filtration. In end-stage renal disease, the kidneys can’t adequately clear toxins like urea and creatinine or regulate fluid and electrolyte balance, so dialysis serves as a mechanical substitute to cleanse the blood and help control fluid status. It also helps stabilize electrolytes and acid-base balance, which is essential for overall homeostasis. However, dialysis is not a cure for kidney disease and does not restore normal kidney function. Patients may still need ongoing medical care, including medications, dietary management, and monitoring for complications, and some may pursue transplantation as a long-term option. Dialysis does not permanently replace the kidney with a donor organ; it provides ongoing filtration support but does not recreate the kidneys themselves.
