4 Hemodialysis with low potassium dialysate *****

Actually also hemodialysis is also used in the patients with renal failure BUT i haven't read about low potassium dialysate. I think they use plain hemo- or peritoneal dialysis.
What was the answer given in the book?

Thanks for the answer, I thought it was that too

But can u believe it-the answer was 1-calcium gluconate, which i believe is absolutely wrong.

But that is wrong!
If you read Harrison's Internal Medicine, the Ca-gluconate is the first choice treatment of hyperkaliemia!
Probably that was error.

administration of calcium gluconate IV is correct answer.
All are treatment of Hyperkalemia, But except ca+ all lower K, ca+ act as antagonist to low K.

You are right!
Ca reduces K effects to cell membranes, not lowers K.
I didn`t pay enough attention.

Ca gluconate is the right answer coz all the others reduce K+ except Ca gluconate..Ca acts on the Heart ..it is given in hyperK+

In hyperkalemia, calcium gluconate may aid in antagonizing the cardiac toxicity provided the patient is not receiving digitalis therapy.

Hyperkalemia is reduced by each of the following except:

1 administration of calcium gluconate IV----------- is to counteract and protect the Heart not to decrese the K+
2 Administration of Glucose, Insulin and sodium bicarbonate IV
3 Oral administration of potassium exchange resins with sorbitol
4 Hemodialysis with low potassium dialysate
