What is the sequence for peritoneal dialysis?

• A. Dialysate is infused into the abdominal cavity and the tubing is unclamped to allow drainage immediately after dwell
• B. Dialysate is infused into the abdominal cavity and allowed to dwell, then drained
• C. Dialysate is never infused
• D. Dialysate is infused and immediately drained with no dwell

Answer: (B)

Peritoneal dialysis relies on a fill-dwell-drain sequence. You infuse dialysate into the abdominal cavity, give it time to dwell so waste products and excess fluid can diffuse from the blood into the dialysate, and then drain it out. The dwell period is essential because, without it, little exchange occurs and toxins and fluid aren’t removed. After the prescribed dwell, drainage completes the exchange, and the cycle can be repeated as prescribed. In practice, this can be done manually or with an automated system, and you monitor for signs of infection and maintain sterile technique throughout the exchanges.
