Question

Use of an artificial kidney during hemodialysis 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 the gastro-intestinal tract

(d) Reduced RBC production

Which of the following options is the most appropriate?

• A. (a) and (d) are correct
• B. (a) and (b) are correct
• C. (b) and (c) are correct
• D. (c) and (d) are correct

Answer 1

The correct option is: D

Explanation of the correct option:

As phosphate ions are also eliminated during dialysis, calcium ions are eliminated along with it. So, there will be reduced absorption of calcium ions from the gastrointestinal tract.

RBC production is also reduced due to reduced erythropoietin hormone which is produced by the glomerulus

Explanation of the incorrect option:

Option A: Dialysis eliminates urea and potassium from the body

Option B: Dialysis eliminates urea and potassium from the body

Option C: Dialysis eliminates urea and potassium from the body

Final answer: Use of an artificial kidney during hemodialysis may result in reduced absorption of calcium ions from the gastrointestinal tract and reduced RBC production.
