Cloudy outflow, abdominal pain, fever, or rebound tenderness - signs of peritonitis; report immediately.

Test yourself first: 5 questions
Question 1 of 5
The nurse is monitoring a client undergoing peritoneal dialysis. The outflow (drained) dialysate is cloudy. Which complication does this finding indicate?
Answer: A. Cloudy or opaque dialysate outflow is the classic sign of peritonitis, the most common serious complication of peritoneal dialysis, usually caused by contamination during exchanges. The nurse should obtain a culture and notify the provider. Clear or pale-yellow outflow is normal; cloudiness signals infection, not simple fluid overload or a kink.
Question 2 of 5
During peritoneal dialysis, the nurse notes that the dialysate outflow is significantly less than the amount instilled. Which is the BEST initial action by the nurse?
Answer: A. Inadequate outflow during peritoneal dialysis is most often due to a positional issue or constipation/full bowel impeding drainage. The nurse first reposition the client (turn side to side) or has them sit up, and checks the catheter for kinks. These simple measures often restore flow before any pharmacologic or provider intervention is needed.
Question 3 of 5
During peritoneal dialysis, the nurse notes that the dialysate outflow is significantly less than the amount instilled. Which nursing action should the nurse take first?
Answer: A. When outflow is inadequate, the catheter may be kinked or the client's position may obstruct drainage. Repositioning the client (turning side to side) and checking the tubing for kinks are simple first measures to promote drainage before notifying the provider.
Question 4 of 5
A client receiving hemodialysis develops nausea, headache, restlessness, and a decreased level of consciousness during the first dialysis session. The nurse suspects which complication?
Answer: A. These are signs of dialysis disequilibrium syndrome, caused by rapid removal of urea and other solutes that creates an osmotic shift of water into the brain, leading to cerebral edema. It is most common during the first few treatments. The dialysis rate is slowed. It is not an air embolism (chest pain, dyspnea) or simple hypotension.
Question 5 of 5
A client with chronic kidney disease on dialysis arrives with shortness of breath, crackles, and a 4-kg weight gain since the last session. The nurse recognizes:
Answer: B. Rapid weight gain, crackles, edema, and dyspnea between dialysis sessions indicate fluid volume overload — anticipate dialysis/ultrafiltration and fluid/sodium restriction; monitor for hyperkalemia too.
Keep the streak going with more questions like these, each with a full rationale.
What is peritoneal dialysis?
Dialysate is instilled into the abdominal cavity via a catheter, dwells while waste and fluid diffuse across the membrane, then is drained out. It can be done at home and offers more independence but carries a high risk of peritonitis. It is an alternative to hemodialysis for ESRD.
Key points to remember
- The process is fill, dwell, and drain; the dwell time allows exchange of wastes and fluid.
- Peritonitis is the most common and serious complication, signaled by CLOUDY drain effluent.
- Drained dialysate (outflow) should be clear and pale yellow; cloudy fluid indicates infection.
- Warming the dialysate before instillation promotes comfort and dilates peritoneal vessels for better exchange.
- Outflow that is less than inflow (fluid retention) may indicate a kinked catheter, constipation, or fibrin clot.
- Higher dextrose concentration dialysate pulls off more fluid but raises blood glucose.
Nursing priorities
- Use strict sterile technique with every exchange and catheter handling.
- Assess the color of outflow each exchange; report cloudy effluent as a sign of peritonitis.
- Track inflow versus outflow volumes and document; warm dialysate before instilling.
- Reposition the patient, check for kinks/constipation if outflow is inadequate.
- Monitor blood glucose because dialysate dextrose is absorbed.
Labs & values
Patient teaching
- Always wash hands and use sterile technique; wear a mask during exchanges.
- Report cloudy fluid, abdominal pain, or fever immediately as signs of infection.
- Keep the catheter exit site clean and dry, prevent constipation, and weigh daily.
Red flags: report now
- Cloudy outflow, abdominal pain, fever, or rebound tenderness - signs of peritonitis; report immediately.
- Never instill cold dialysate or use breaks in sterile technique.
- Significant fluid retention (much less drained than instilled) with respiratory difficulty - escalate.
- Bloody or brown effluent (beyond the first few exchanges) - report.
