A

True or False: Osmosis is the process by which solutes move from an area of higher concentration to an area of lower concentration in dialysis.

False

True or False: An arteriovenous graft (AVG) has a lower risk of infection than an arteriovenous fistula (AVF).

False

True or False: Hemodialysis removes waste products and excess fluid by applying a pressure gradient across a semipermeable membrane.

True

True or False: Peritoneal dialysis is contraindicated in patients with a history of multiple abdominal surgeries.
