Answer:
Correct Answer: A
Solution:
- The use of an artificial kidney during hemodialysis is intended to remove waste products and excess substances from the blood, mimicking the function of a healthy kidney. However, it can have some side effects or limitations.
(i) Nitrogenous waste build-up in the body: This is unlikely to occur during effective hemodialysis, as the primary purpose of the procedure is to remove nitrogenous wastes like urea from the blood.
(ii) Non-elimination of excess potassium ions: Hemodialysis is designed to remove excess potassium ions from the blood, so this is also unlikely to occur if the procedure is functioning properly.
(iii) Reduced absorption of calcium ions from the gastrointestinal tract: This is not directly related to the function of hemodialysis. Calcium absorption from the gastrointestinal tract is more related to dietary intake and vitamin D levels.
(iv) Reduced RBC production: This can occur because the kidneys produce erythropoietin, a hormone that stimulates red blood cell production. In patients with kidney failure, erythropoietin production is often reduced, leading to anemia. Hemodialysis itself does not correct this issue, so patients may still experience reduced RBC production.
