Final answer:
The statement is false. Peritoneal dialysis can often be performed at home, while hemodialysis typically occurs a few times weekly at a medical facility due to the frequent need for waste removal in patients with kidney failure. Hemodialysis uses a semipermeable membrane to filter wastes while retaining blood cells.
Step-by-step explanation:
The statement "Patients receiving peritoneal dialysis must report to the hospital or dialysis center for the procedure" is false. Peritoneal dialysis is a type of dialysis that can often be done at home by the patient or a caregiver after proper training, and does not necessitate a visit to the hospital or a dialysis center for each treatment. This method involves installing a catheter into the peritoneal cavity, through which a dialysate solution is infused and drained several times a day, allowing the peritoneal membrane to serve as the filtration medium to remove waste products from the blood. The frequency of hemodialysis, another form of dialysis, is due to the need to consistently remove waste products from the bloodstream several times a week, as the kidneys are not able to perform this function adequately in patients with renal failure. In hemodialysis, a semipermeable membrane in the dialysis machine allows for the diffusion of wastes like urea, while retaining elements like red blood cells within the bloodstream.
Direct supervision of a registered nurse in hemodialysis is critical because nurses must monitor patients' vitals and be ready to respond to any immediate needs before and during the treatment. The nurses are also responsible for preparing solutions and equipment to ensure minimal risk of infection and accurate dialysis treatment.
Dialysis machines use a semipermeable membrane that is likely permeable to urea but impermeable to red blood cells, ensuring that blood cells remain in the blood while waste products such as urea are removed.
