Which three statements about dialysis are true? a. it’s a time-consuming procedure. b. it requires the patient to be on antirejection medication. c. it uses a machine to purify blood. d. it’s a temporary remedy for renal failure. e. it requires matching the patient’s blood with that of the donor.

A, C, and D are true.

Please correct me if I'm wrong :)

The true statements are A, C and D.

Explanation:

During kidney failure dialysis is carried out to remove the metabolic waste from the blood. Excess of waste, salt or water must be removed from the body or else there concentrations will increase to a toxic level in the blood. This function is usually performed by kidney, but if it fails to work then dialysis is carried out. There is no transplantation of graft so option B and option E are ruled out. Only when transplantation is done, person has to take antirejection medication to prevent rejection of graft and donors' blood must match with the recipients blood.
