After performing a peritoneal dialysis session, which of the following might the nurse expect regarding dialysis outflow?

During a peritoneal dialysis session, the expectation regarding dialysis outflow is that it may be higher than inflow due to absorption. This phenomenon occurs because, while the dialysis solution is instilled into the peritoneal cavity, some of the fluid can be absorbed by the body's tissues or blood vessels during the dwell time, leading to a greater volume of fluid being returned via the outflow.

Moreover, the composition of the dialysis solution, including osmotic substances like dextrose, encourages fluid movement to balance concentrations inside and outside the peritoneal cavity. This osmotic gradient can draw extra fluid into the dialysate, which is then evacuated, contributing to a higher outflow volume.

Understanding the fluid dynamics involved in peritoneal dialysis is crucial, as it directly impacts the effectiveness of the treatment in removing waste products and excess fluids from the body. Thus, anticipating higher outflow than inflow helps healthcare providers assess the efficiency of the dialysis process and manage patient care effectively.
