In peritoneal dialysis, which is a common cause of insufficient outflow and what is an appropriate intervention?

• A. Infection at the catheter site; administer antibiotics and replace the catheter.
• B. Constipation; assess bowel pattern, soften stool, check for abdominal distention, check tubing for kinks, reposition and keep drainage bag below abdomen.
• C. Excessive physical activity; advise bed rest.
• D. Catheter dislodgement; schedule immediate surgery.

Answer: (B)

In peritoneal dialysis, outflow relies on gravity and normal intra-abdominal pressure. Constipation raises intra-abdominal pressure and can press on the catheter or kink the tubing, blocking drainage. The best intervention centers on relieving constipation and ensuring the drainage pathway is clear: assess bowel pattern and stool form, soften stool with prescribed laxatives or stool softeners, monitor for abdominal distention, inspect the catheter tubing for kinks or occlusions, reposition the patient to optimize flow, and keep the drainage bag positioned below the abdomen to use gravity for drainage.
