Bicarbonates are added to a dialysate for a person with acidosis. In dialysis, the dialysate solution is used to remove waste and excess fluid from the body. It is important to make sure the composition of the dialysate is appropriate for the patient's needs, and bicarbonates may be added to correct acidosis. The other statements are incorrect. The chemical composition of the dialysate does affect the movement of solutes across the semipermeable membrane, substances will only diffuse out of the blood if their concentration is higher in the blood than in the dialysate, and dialysate does contain urea and potassium. Bicarbonates are added to a dialysate for a person with acidosis. Dialysis removes excess acids from the body, and bicarbonates are added to the dialysate solution to help correct the acid-base balance. Option A is incorrect because the chemical composition of the dialysate does affect the movement of solutes across the semipermeable membrane. Option C is incorrect because when the concentration of a substance is higher in the blood than in the dialysate, the substance diffuses into the dialysate. Option D is incorrect because dialysate does contain urea and potassium, as well as other wastes and electrolytes.
