I don't know how to explain or if Ive got my homework answer correct. The question is: A patient on dialysis has a high level of urea, a high level of sodium and a low level of potassium in the blood. Why is the dialyzing solution prepared with a high level of potassium but no sodium or urea?
A dialysis solution contains no sodium or urea so that these substances will flow out of the blood into the dialyzing solution. High levels of potassium are maintained in the dialyzing solution so that the potassium will dialyze into the blood to increase the K+ level in the bloodstream back to a more normal range.
