Dialysis করা প্রয়োজন হয় কোন রোগে?

The answer is correct because dialysis is a medical treatment primarily used for patients with renal failure, also known as kidney failure. In renal failure, the kidneys are unable to remove waste products and excess fluids from the blood. Dialysis performs the role of the kidneys by filtering the blood and removing these harmful substances.

Here is a brief description of the other options:

    
• Respiratory failure: This condition occurs when the lungs cannot provide enough oxygen to the body or cannot remove carbon dioxide adequately.
    
• Hepatic failure: This refers to severe liver dysfunction and is not treated with dialysis.
    
• Cardiac failure: This involves the heart's inability to pump effectively, and it also does not require dialysis.

Therefore, among the options given, renal failure is the only condition that necessitates dialysis treatment.
