What are the phases of a peritoneal dialysis exchange?

The phases of a peritoneal dialysis exchange consist of drain, fill, and dwell as essential steps. The correct choice reflects the correct sequence of fluid management essential for maintaining effective dialysis therapy.

During the draining phase, the solution that has absorbed waste products through the peritoneal membrane is removed from the abdominal cavity. This step is crucial as it ensures that toxins and excess fluid are effectively cleared from the patient’s system.

Then, during the fill phase, a fresh dialysate solution is introduced into the peritoneal cavity. This step is vital as it replaces the used solution with a new one that will facilitate the exchange of waste products and fluids through the peritoneal membrane.

Once the solution is filled, the dwell phase begins. This phase allows the dialysate to remain in the abdomen for a designated period, giving it time to equilibrate, absorb toxins and waste, and remove excess fluid from the bloodstream. This equilibrium phase is essential for optimizing the dialysis process.

The incorrect aspects in the other options typically involve misordering these critical phases or including steps that are not recognized in standard protocol for peritoneal dialysis exchanges. The established procedure ensures that each phase follows a logical progression leading to effective dialysis treatment.
