Hemodialysis involves

• A. An arteriovenous fistula is created for access
• B. Cleansing fluid injected into the peritoneal cavity
• C. Does not require regular visits
• D. Uses a dialysis catheter inserted into the urethra

Answer: (A)

Hemodialysis requires a reliable vascular access to draw blood from the body, send it through a dialyzer, and return it for cleansing. The single best way to achieve this is a surgically created arteriovenous fistula in the arm, which connects an artery to a vein to provide high-flow access that can endure repeated treatments. Because patients typically undergo dialysis sessions regularly—often three times a week—the access needs to be usable long-term and dialysis centers schedule these ongoing visits. The other statements reflect different ideas: injecting cleansing fluid into the peritoneal cavity describes peritoneal dialysis, not hemodialysis. Saying it does not require regular visits is inaccurate because ongoing treatment is needed. Using a dialysis catheter inserted into the urethra is anatomically incorrect—the access for hemodialysis is placed in a vein (or via a graft), not the urethra.
