Cloudy effluent, abdominal pain, fever, or rebound tenderness — suspect peritonitis: send effluent for cell count and culture as ordered and notify the provider now; delayed antibiotics raise mortality.

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 run into the abdomen through a catheter, left to dwell while wastes diffuse into it and its dextrose pulls off extra water, then drained. It is done at home every day, by hand (CAPD) or overnight on a cycler (APD), and offers more independence than hemodialysis. Peritonitis is the most common serious complication, and cloudy effluent is its hallmark. The NCLEX-RN test plan lists caring for a client receiving PD under Physiological Adaptation.
Key points to remember
- Cycle: fill → dwell → drain. Outflow should exceed inflow; the extra volume is the fluid removed.
- Wastes such as urea, creatinine, and potassium diffuse into the dialysate; its dextrose pulls off extra water (ultrafiltration).
- CAPD: manual exchanges, typically 4 dwells a day of 1.5–3.0 L, each exchange taking about 30–40 minutes. APD: a cycler runs exchanges overnight for about 7–10 hours.
- Peritonitis: abdominal pain and/or cloudy effluent. Diagnosis needs 2 of 3: symptoms, effluent WBC above 100/µL with more than 50% neutrophils, or a positive culture.
- Poor outflow: constipation is the main cause; kinks, fibrin, or catheter migration are others.
- Dextrose absorption raises blood glucose; stronger dextrose removes more fluid but adds more glucose.
- Other complications: exit-site or tunnel infection, hernias (often umbilical), dialysate leaking into the chest (right-sided pleural effusion with shortness of breath), and low potassium or sodium.
Nursing priorities
- Use strict sterile technique with hand hygiene and a mask for every exchange, because the catheter is a direct route for bacteria into the peritoneum.
- Inspect every drain bag for clarity and color, because cloudy effluent is the key sign of peritonitis.
- Record inflow and outflow volumes and daily weight, because outflow less than inflow means fluid is being retained.
- Warm dialysate before instilling, because warming promotes comfort and dilates peritoneal vessels for better exchange.
- If outflow is slow, turn the client side to side or have them walk, check tubing for kinks, and treat constipation, because these restore drainage.
- Monitor glucose, potassium, sodium, and albumin, because PD can cause hyperglycemia, hypokalemia, hyponatremia, and albumin loss.
Labs & values
Worked example
- Cue: A client on CAPD reports belly pain, and the drained bag is cloudy.
- Meaning: Likely peritonitis, the most serious PD complication.
- Action: Save the bag, send effluent for cell count and culture as ordered, notify the provider, and expect prompt antibiotics.
- Evaluation: Effluent clears and pain eases within 48–72 hours of antibiotics; review exchange technique with the client.
Patient teaching
- Wash your hands, wear a mask, and keep the area clean for every exchange.
- Check every drained bag. Call right away if it is cloudy or if you have belly pain or fever.
- Clean the catheter exit site every day, use the antibiotic cream if prescribed, and keep it dry; report redness or pus.
- Prevent constipation, weigh yourself daily, and track how much fluid drains out.
Common mistakes
- Treating cloudy effluent as normal. Clear, pale-yellow effluent is expected; cloudy means peritonitis until proven otherwise.
- Expecting outflow to be less than inflow. It should be more.
- Forgetting constipation as the leading cause of poor outflow.
- Missing hyperglycemia in a client on PD, since the dextrose is absorbed.
Red flags: report now
- Cloudy effluent, abdominal pain, fever, or rebound tenderness — suspect peritonitis: send effluent for cell count and culture as ordered and notify the provider now; delayed antibiotics raise mortality.
- Outflow much less than inflow with weight gain or trouble breathing — fluid overload: escalate.
- Sudden shortness of breath with a right-sided pleural effusion — possible dialysate leak into the chest: notify the provider.
- Pus, redness, or swelling at the exit site or along the tunnel — report a possible catheter infection.
- Bloody or brown effluent beyond the first few exchanges — report it.
