Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
In kidney dialysis, which of the following are usually at a higher concentration in dialysis fluid than in a patient’s blood?I. hydrogen carbonate ions (HCO3-)II. calcium ions (Ca2+)III. potassium ions (K+)
A
I and II only
B
I and III only
C
II and III only
D
I, II and III
Explanation: 

Detailed explanation-1: -The dialysate concentration of glucose is commonly between 100 and 200 mg/dL. Freshly prepared dialysate solution circulates continuously to the dialyzer in the extracorporeal circuit. After making a single pass through the dialyzer, the effluent dialysate goes to the drain.

Detailed explanation-2: -So, the correct answer is ‘Salt and urea’

Detailed explanation-3: -The dialysis fluid contains the same concentration of glucose and salts as normal blood plasma so there is no net movement of glucose out of the blood by diffusion.

Detailed explanation-4: -Dialysate, also called dialysis fluid, dialysis solution or bath, is a solution of pure water, electrolytes and salts, such as bicarbonate and sodium. The purpose of dialysate is to pull toxins from the blood into the dialysate. The way this works is through a process called diffusion.
