Dialysis is a procedure that is a substitute for many of the normal functions of the kidney.

1. To remove waste, salt and extra water to prevent them from building up in the body.
2. To keep a safe level of certain chemicals in your blood, such as potassium, sodium and bicarbonate helping to control blood pressure.
3. There will be reduced absorption of calcium ions from gastrointestinal tract.
4. RBC production will be reduced, due to reduced erythropoietin hormone.

Correct answer: To remove waste, salt and extra water to prevent them from building up in the body.

Solution

Dialysis substitutes for the kidney’s excretory function by removing waste products, excess salts, and extra water from the blood. This prevents harmful buildup when the kidneys can no longer do this effectively.
