Question

Use of artificial kidney during haemodialysis may result in :
(a) Nitrogenous waste build-up in the body
(b) Non-elimination of excess potassium ions
(c) Reduced absorption of calcium ions from gastro-intestinal tract
(d) Reduced RBC production

Which of the following options is the most appropriate?
(a) and (b) are correct
(b) and (c) are correct
(c) and (d) are correct
(a) and (d) are correct

Answer 1

Kidneys are a bean shaped structure which are present on the other side of the spine. Their role is to filter blood and remove waste materials.

Complete answer:
Haemodialysis is a treatment to filter wastes and water from your blood, as your kidneys did when they were healthy. Haemodialysis helps control blood pressure and balance important minerals like potassium, sodium, and calcium, in your blood.Haemodialysis is a procedure where a dialysis machine and a special filter called an artificial kidney, used to clean your blood.
Let's discuss the above option and find out the correct answer.
a)Nitrogenous waste build-up in the body: This statement is incorrect, because during the haemodialysis process or dialysis process, it eliminates the urea which is accumulated in the body. So nitrogenous waste does not build up in the body. Hence option a is incorrect.
b)Non-elimination of excess potassium ions: This statement is incorrect, because during the haemodialysis process or dialysis process, it also eliminates the potassium from the body. So excess potassium does not present in the body. Hence option b is incorrect.
c)Reduced absorption of calcium ions from gastro-intestinal tract: During haemodialysis process phosphate ions along with that calcium ions are eliminated. So, there will be reduced absorption of calcium ions from the gastro-intestinal tract. Hence option c is correct.
d)Reduced RBC production: Due to reduced erythropoietin hormone RBCs production will be reduced. Hence option d is correct.

Hence the option "c” (c) and (d) are correct.

Note: Due to the malfunction of the kidney, it does not do proper work that's why it can lead to accumulation of urea in the blood, this condition is called uremia. It is highly harmful and can cause kidney failure.
