BONENT Certified Peritoneal Dialysis Nurse Practice Exam

Free BONENT Certified Peritoneal Dialysis Nurse Practice Sample Questions & Answers

Question 1

A patient receiving peritoneal dialysis reports severe abdominal pain, cloudy dialysis effluent, and a low-grade fever. Which complication should the nurse suspect FIRST?

A. Hyperglycemia
B. Peritonitis
C. Catheter migration
D. Fluid overload

Correct Answer: B. 

Explanation:
Peritonitis is one of the most serious complications associated with peritoneal dialysis and commonly presents with abdominal pain, fever, and cloudy dialysate effluent. The nurse should recognize these findings as possible signs of infection and follow the appropriate protocol, including obtaining cultures if ordered and notifying the healthcare provider promptly. Catheter-related issues may cause drainage problems but typically do not produce cloudy fluid and systemic symptoms. Fluid overload may occur in dialysis patients but does not usually cause abdominal pain or cloudy effluent. Early recognition and treatment of peritonitis are essential to prevent complications such as catheter failure or loss of peritoneal dialysis effectiveness.

Question 2

A nurse is teaching a patient how to perform peritoneal dialysis exchanges at home. Which instruction is MOST important for preventing infection?

A. Perform exchanges quickly to reduce treatment time.
B. Maintain strict aseptic technique during every exchange.
C. Store dialysis supplies in the bathroom for convenience.
D. Reuse disposable dialysis equipment when possible.

Correct Answer: B. 

Explanation:
Strict aseptic technique is the foundation of infection prevention in peritoneal dialysis. Because the peritoneal cavity is accessed repeatedly through a catheter, contamination during exchanges can introduce bacteria and lead to peritonitis. Patients should receive education on hand hygiene, clean workspace preparation, proper connection techniques, and safe handling of dialysis supplies. Speed should never replace safety, and disposable equipment should not be reused unless specifically designed and approved for reuse. Proper patient education and adherence to infection prevention practices significantly reduce complications and improve long-term dialysis outcomes.

Question 3

Which finding indicates that a patient undergoing peritoneal dialysis may have inadequate fluid removal?

A. Clear effluent after exchange
B. Stable body weight
C. Increasing edema and shortness of breath
D. Improved blood pressure control

Correct Answer: C. 

Explanation:
Increasing edema, weight gain, and shortness of breath may indicate fluid retention and inadequate ultrafiltration in a patient receiving peritoneal dialysis. Nurses should assess fluid balance, review dialysis exchanges, monitor weight trends, and evaluate treatment effectiveness. Clear effluent is generally an expected finding and does not indicate inadequate dialysis. Stable weight and improved blood pressure control suggest better fluid management. Identifying signs of fluid overload early helps prevent complications such as pulmonary congestion, hypertension, and worsening cardiovascular strain.

Question 4

A patient using continuous ambulatory peritoneal dialysis (CAPD) asks why multiple exchanges are performed throughout the day. What is the BEST explanation by the nurse?

A. “The exchanges replace your body’s ability to produce insulin.”
B. “The exchanges allow removal of waste products and excess fluid through the peritoneal membrane.”
C. “The exchanges permanently restore kidney function.”
D. “The exchanges prevent all kidney-related complications.”

Correct Answer: B. 

Explanation:
Continuous ambulatory peritoneal dialysis uses the peritoneal membrane as a natural filter to remove waste products, electrolytes, and excess fluid from the bloodstream. Dialysis solution is infused into the peritoneal cavity, allowed to dwell, and then drained along with collected waste products. CAPD does not restore kidney function but provides renal replacement therapy for patients with kidney failure. It also does not eliminate every possible complication associated with kidney disease. Patient education is essential to ensure realistic expectations and proper treatment adherence.

Question 5

A nurse notices that a peritoneal dialysis patient has poor dialysate outflow during an exchange. What should the nurse assess FIRST?

A. Patient’s dietary preferences
B. Catheter position and possible mechanical obstruction
C. Patient’s vision changes
D. Medication refill schedule

Correct Answer: B. 

Explanation:
Poor dialysate drainage is often related to mechanical problems such as catheter displacement, kinking, constipation causing pressure on the catheter, or fibrin blockage. The nurse should first assess potential causes affecting catheter function, including checking tubing position and patient comfort. Other interventions may be required depending on findings and provider guidance. Dietary preferences, vision changes, and medication schedules are important aspects of overall patient care but are not immediate priorities when addressing impaired dialysis flow. Maintaining effective catheter function is essential for successful peritoneal dialysis therapy.

Question 6

Which laboratory value is MOST important for monitoring a patient receiving peritoneal dialysis?

A. Serum creatinine and electrolyte levels
B. White blood cell count only
C. Blood type
D. Liver enzymes only

Correct Answer: A. 

Explanation:
Monitoring serum creatinine and electrolyte levels helps evaluate kidney function, dialysis effectiveness, and metabolic balance in patients receiving peritoneal dialysis. Electrolyte abnormalities, including potassium and sodium disturbances, can create serious complications if not identified and managed appropriately. While white blood cell counts may be useful when infection is suspected, they do not provide a complete picture of dialysis adequacy. Blood type and liver enzymes are not primary indicators of dialysis effectiveness. Regular laboratory monitoring allows healthcare providers to adjust treatment plans and maintain safe patient outcomes.

Question 7

A patient with peritoneal dialysis develops redness, drainage, and tenderness around the catheter exit site. Which action should the nurse take?

A. Document the finding and continue routine care only.
B. Recognize possible exit-site infection and notify the healthcare provider.
C. Remove the catheter immediately without an order.
D. Encourage the patient to ignore the symptoms.

Correct Answer: B. 

Explanation:
Redness, drainage, and tenderness around the catheter exit site may indicate an infection that requires prompt evaluation and treatment. Exit-site infections can progress and increase the risk of serious complications, including tunnel infections and peritonitis. The nurse should assess the site, document findings, follow infection-control procedures, and notify the healthcare provider according to protocol. Removing the catheter without appropriate evaluation is unsafe. Early intervention improves the likelihood of preserving catheter function and preventing more severe infections.

Question 8

Which patient statement demonstrates correct understanding of peritoneal dialysis care?

A. “I can skip hand hygiene if my supplies are clean.”
B. “I should report cloudy drainage or abdominal discomfort to my healthcare team.”
C. “I should store supplies in areas with moisture and heat.”
D. “I do not need regular follow-up appointments.”

Correct Answer: B. 

Explanation:
Patient education is a critical component of successful peritoneal dialysis management. Patients should understand that cloudy effluent, abdominal pain, fever, or changes around the catheter site may indicate infection or complications requiring medical attention. Proper hand hygiene, safe storage of supplies, and regular follow-up appointments are essential parts of treatment. Self-management skills help patients recognize problems early, maintain treatment effectiveness, and reduce preventable complications associated with home dialysis therapy.

Question 9

What is the PRIMARY purpose of assessing peritoneal dialysis adequacy?

A. To determine whether dialysis is effectively removing waste and maintaining patient health
B. To decide the patient’s blood type
C. To eliminate the need for monitoring laboratory values
D. To determine the patient’s preferred dialysis schedule only

Correct Answer: A. 

Explanation:
Assessment of dialysis adequacy determines whether the prescribed peritoneal dialysis treatment is effectively removing toxins and excess fluid while maintaining acceptable metabolic balance. Evaluation may include clinical assessment, laboratory results, fluid status, and measures of dialysis performance. Adequate dialysis supports patient well-being and helps guide treatment adjustments when necessary. Dialysis adequacy does not replace routine monitoring or determine unrelated factors such as blood type. Regular evaluation ensures that patients receive appropriate renal replacement therapy based on their individual needs.

Question 10

A nurse is caring for a patient beginning automated peritoneal dialysis (APD). Which statement BEST describes this therapy?

A. It uses a machine to perform multiple exchanges, often during sleep.
B. It requires permanent hospitalization during treatment.
C. It completely replaces the need for kidney function monitoring.
D. It uses blood filtration through an external machine.

Correct Answer: A. 

Explanation:
Automated peritoneal dialysis (APD) uses a cycler machine to perform scheduled exchanges of dialysis solution, commonly during nighttime hours while the patient sleeps. This approach allows many patients greater daytime flexibility compared with continuous ambulatory peritoneal dialysis. APD still requires careful monitoring, patient education, infection prevention, and regular healthcare follow-up. It does not involve external blood filtration, which is a feature of hemodialysis. Understanding the differences between dialysis modalities helps nurses provide appropriate education and support for patients choosing or managing renal replacement therapies.
