A nephrology nurse is providing information to a patient who is considering peritoneal dialysis as a treatment modality for his end-stage renal disease. Which of the following is a goal of peritoneal dialysis?
A) To provide a faster exchange than hemodialysis
B) To consistently remove wastes, fluid, and reestablish electrolyte balance
C) To maintain dialysis treatment until a hemodialysis access matures
D) To complete as many exchanges as possible in 6 hours
Ans: B
Feedback: The goals of peritoneal dialysis are to remove toxic substances and metabolic wastes and to reestablish normal fluid and electrolyte balance. Peritoneal dialysis is a treatment modality performed daily; thus, it provides a consistent removal of wastes and fluids. Hemodialysis, in contrast, is an intermittent therapy performed 3 times a week that does not provide consistent fluid and waste removal and results in greater fluctuations in electrolyte and laboratory values. Peritoneal dialysis may be the treatment of choice for patients with renal failure who are unable or unwilling to undergo hemodialysis or renal transplantation. Patients who are susceptible to the rapid fluid, electrolyte, and metabolic changes that occur during hemodialysis experience fewer of these problems with the slower rate of peritoneal dialysis.
