Question

Given below are two statements:
Statement (I): Peritoneal dialysis is as efficient as haemodialysis.
Statement (II): Secretion of erythropoietin, renin and calcitriol by kidneys is not possible using dialysis machine.
In light of the above statements, choose the most appropriate answer from the options given below.

• A. Both Statement (I) and Statement (II) are correct.
• B. Both Statement (I) and Statement (II) are incorrect.
• C. Statement (I) is correct but Statement (II) is incorrect.
• D. Statement (I) is incorrect but Statement (II) is correct.

Hint:

A dialysis machine only removes wastes and cannot replace the hormone-producing role of the kidney.

Answer 1

The Correct Option is D

Step 1: Understanding the Concept
Dialysis helps remove nitrogenous wastes and extra fluid from the blood when the kidneys fail.

Step 2: Statement (I)
Peritoneal dialysis uses the peritoneum as the filtering membrane and is slower and less efficient than haemodialysis. Statement (I) is incorrect.

Step 3: Statement (II)
A dialyser only filters wastes. It cannot make erythropoietin, renin or calcitriol, which are secreted by the kidney. Statement (II) is correct.

Final Answer:
Statement (I) is incorrect but Statement (II) is correct. \[ \boxed{\text{(D) }\text{Statement (I) is incorrect but Statement (II) is correct}} \]
