Use of an artificial kidney during hemodialysis may result in:

1. Nitrogenous waste build-up in the body.
2. Non-elimination of excess potassium ions.
3. Reduced absorption of calcium ions from gastro-intestinal tract.
4. Reduced RBC production.

Correct answer: Reduced RBC production.

Solution

Hemodialysis can lower the kidney’s normal endocrine function, especially erythropoietin production. Less erythropoietin means the bone marrow makes fewer red blood cells, so RBC production falls.
