A client with chronic renal failure has asked to be evaluated for a home continuous ambulatory peritoneal dialysis (CAPD) program. The nurse should explain that the major advantage of this approach is that it:
A. Is relatively low in cost.
B. Allows the client to be more independent.
C. Is faster and more efficient than standard peritoneal dialysis.
D. Has fewer potential complications than standard peritoneal dialysis.
Correct Answer: B. Allows the client to be more independent.
The major benefit of CAPD is that it frees the client from daily dependence on dialysis centers, home health care personnel, and machines for life-sustaining treatment. Independence is a valuable outcome for some people. Continuous ambulatory peritoneal dialysis (CAPD) represents a new method for the treatment of end-stage renal disease. It offers the advantages of greater clearance of higher molecular-weight substances than during haemodialysis, good control of blood pressure, marked improvement of anemia, and unrestricted diet.
Option A: CAPD is costly and must be done daily. In many developing countries, the annual cost of continuous ambulatory peritoneal dialysis (CAPD) is greater than the per-capita gross national income (GNI). The median cost of a 2-L bag of peritoneal dialysis (PD) fluid is around US$5. The absolute cost of PD fluid among countries with significant differences in per-capita GNI actually varies very little. Thus, most renal failure patients can be expected to have problems accessing PD therapy in developing countries in Asia.
Option C: Furthermore, CAPD is a time-consuming procedure. In spite of the need for technical improvements, CAPD is even now, for selected patients, a valuable alternative treatment to intermittent dialysis methods.
Option D: Side effects and complications are similar to those of standard peritoneal dialysis. In contrast, the risks of peritonitis, hypoproteinemia, and hypertriglyceridemia are major disadvantages.
