A nurse is caring for a 45-year-old client with end-stage renal disease who has been receiving continuous ambulatory peritoneal dialysis (CAPD) for 6 months. During a routine home visit, the nurse assesses the client and reviews the dialysis records. Which assessment finding would indicate the most serious complication requiring immediate intervention?
1Cloudy dialysate outflow with abdominal pain and fever
2Decreased ultrafiltration with fluid retention
3Exit site redness with purulent drainage
4Respiratory distress with decreased breath sounds bilaterally✓ 정답
해설
Respiratory distress with decreased breath sounds indicates potential pleural effusion or pneumothorax, which are life-threatening complications requiring immediate intervention.
Core Nursing Explanation
This question tests the nurse's ability to prioritize complications in a patient on Continuous Ambulatory Peritoneal Dialysis (CAPD). The key is to identify which finding represents an immediate, life-threatening risk to the patient's airway, breathing, or circulation (ABCs), versus a serious but more localized or chronic complication.
Key Concept Analysis
The core theme is complication prioritization in CAPD. CAPD involves instilling dialysate into the peritoneal cavity via a catheter. Complications range from infections (peritonitis, exit-site infection) to mechanical/physiological issues (ultrafiltration failure, hernia) and rare but severe complications like pleuroperitoneal communication.
Answer RationaleKey Point!Option ④, "Respiratory distress with decreased breath sounds bilaterally," is correct because it indicates a direct threat to the patient's breathing. In CAPD, this scenario strongly suggests a pleural effusion, often due to a diaphragmatic defect (pleuroperitoneal leak) allowing dialysate to move into the pleural space. This can cause significant respiratory compromise, hypoxia, and respiratory failure, requiring immediate cessation of dialysis, drainage of the effusion, and possibly surgical intervention. It is the most acute threat to life among the options.
Distractor Analysis
Option ① (Cloudy dialysate, abdominal pain, fever): This is the classic triad for peritonitis, a serious and common complication of CAPD. However, it is not typically an immediate life-threatening emergency if recognized and antibiotic treatment is initiated. The priority is high, but the threat to vital functions is not as immediate as respiratory failure.
Option ② (Decreased ultrafiltration, fluid retention): This indicates ultrafiltration failure, a long-term complication related to peritoneal membrane dysfunction. It requires adjustment of the dialysis prescription (e.g., using icodextrin solution) but is a chronic management issue, not an acute emergency.
Option ③ (Exit site redness with purulent drainage): This indicates a localized exit-site infection. While it requires prompt treatment with antibiotics to prevent progression to peritonitis or tunnel infection, it is not immediately life-threatening.
Related Concepts
The nursing process requires constant prioritization using frameworks like ABCs (Airway, Breathing, Circulation) and Maslow's Hierarchy of Needs. Any finding that compromises a physiological need (like oxygenation) takes precedence over other serious but non-life-threatening problems.

Key Findings
Priority Level
Immediate Action
Pleuroperitoneal Leak (Effusion)
Respiratory distress, decreased breath sounds, possible chest pain, dyspnea on exertion (often right-sided)
HIGHEST (Life-threatening)
Stop CAPD, assess airway/breathing, notify provider, prepare for chest X-ray/thoracentesis
Review dialysis regimen, consider different dialysate concentrations (e.g., 4.25% dextrose) or icodextrin
Anatomy, Physiology & Pharmacology Points
Anatomy: The peritoneum is a semi-permeable membrane lining the abdominal cavity. The diaphragm separates the peritoneal and pleural cavities. A defect can allow fluid to track upward.
Physiology: Dialysis works via diffusion (waste removal) and osmosis (fluid removal using hypertonic dextrose solutions). Ultrafiltration failure occurs when the osmotic gradient is lost or the membrane is damaged.
Pharmacology: Peritonitis treatment involves intraperitoneal (IP) antibiotics, often first-generation cephalosporins (e.g., cefazolin) and aminoglycosides (e.g., gentamicin), based on culture results.
Memory Tips
P for Priority Problems: Think "Pulmonary" (Pleural effusion) over "Peritonitis." When breathing is compromised, it's always the top priority.
CAPD Complications ABCs:Airway/Breathing first (Effusion), Circulation/Infection next (Peritonitis), then Dialysis adequacy (Ultrafiltration).
High-Frequency NCLEX Topics
NCLEX frequently tests priority setting and recognition of life-threatening complications. For dialysis patients, know that any sign of respiratory compromise (dyspnea, distress, abnormal breath sounds) is a RED FLAG requiring immediate action, as it can indicate fluid overload, pulmonary edema, or in CAPD, a pleural effusion.
Watch Out for Question Variations!
Instead of asking for the "most serious" finding, the question might present a patient with multiple symptoms and ask for the "priority nursing action" (Answer: Assess respiratory status and oxygen saturation).
The scenario could shift to Hemodialysis (HD) and test for complications like air embolism (sudden dyspnea, chest pain, coughing) or disequilibrium syndrome (headache, confusion, seizures).
Nursing Clinical Practice GuideClinical Scenario: You are a home health nurse visiting Mr. Chen, a 45-year-old with ESRD on CAPD. During your assessment, he reports sudden onset of shortness of breath that began about an hour after his last dialysate exchange. He appears anxious, is using accessory muscles to breathe, and his SpO2 is 92% on room air. Auscultation reveals diminished breath sounds at the right lung base.
Nursing Intervention Strategy:
Intervention: Apply supplemental oxygen via nasal cannula to maintain SpO2 > 95%. Assist the patient into a position of comfort (often high-Fowler's) to maximize lung expansion.
Communication & Orders: Immediately contact the nephrologist or on-call provider. Report your findings succinctly: "Patient on CAPD with acute respiratory distress and diminished breath sounds, suspect pleuroperitoneal leak."
Dialysis Management: Instruct the patient to drain the peritoneal cavity and keep it empty. Do not instill new dialysate. This reduces intra-abdominal pressure and may limit further fluid shift into the chest.
Preparation for Transfer: Prepare for possible hospital transfer. Anticipate orders for a chest X-ray, thoracentesis, and a temporary switch to hemodialysis.
Patient Safety and Precautions:
Never ignore new-onset respiratory symptoms in a CAPD patient. Assume it is related to the dialysis until proven otherwise.
When a pleural effusion is suspected, the peritoneal cavity should be kept dry. The patient may need temporary hemodialysis access.
Educate all CAPD patients to report any difficulty breathing, chest pain, or unexplained cough immediately.
Don gloves. Observe effluent in the drainage bag for cloudiness.
Using aseptic technique, obtain a sample of the cloudy dialysate for cell count, differential, and culture.
Administer intraperitoneal antibiotics as per protocol (e.g., "antibiotic in the bag"). This often involves adding the prescribed dose to the next exchange.
Monitor for fever, worsening pain, and changes in effluent clarity.
Key Difference: Peritonitis management is protocol-driven and urgent, but the patient's vital signs (especially respiration) are typically stable. In respiratory distress, managing the airway and breathing comes before any diagnostic procedure for peritonitis.
A Word from Your Senior Nurse
"In the world of dialysis nursing, your eyes and ears are your best assessment tools. A patient telling you they 'just can't catch their breath' is a five-alarm fire, especially in CAPD. While peritonitis is more common, respiratory distress is far more dangerous. On the NCLEX and in real life, always default to the ABCs. If breathing is compromised, that's your answer. This mindset protects your patient and demonstrates the critical thinking that defines our profession."
Continuous Ambulatory Peritoneal Dialysis — A type of peritoneal dialysis where the patient manually performs dialysate exchanges 4-5 times daily, with the dialysate remaining in the peritoneal cavity between exchanges. It provides continuous clearance and is performed independently by the patient at home.
Pleuroperitoneal Communication — An abnormal connection (often a congenital or acquired defect in the diaphragm) between the peritoneal and pleural cavities. In CAPD, this allows dialysate to flow into the pleural space, causing a hydrothorax (pleural effusion) and respiratory symptoms.
Peritonitis — Infection and inflammation of the peritoneum, a serious complication of peritoneal dialysis. Diagnosed by the presence of two of the following: cloudy dialysate effluent, abdominal pain, and >100 WBC/μL in dialysate with >50% neutrophils.
Ultrafiltration Failure — The inability of peritoneal dialysis to adequately remove fluid, leading to chronic fluid overload. Causes include peritoneal membrane failure, rapid solute absorption, and lymphatic reabsorption.
Exit-Site Infection — A localized infection at the skin site where the peritoneal dialysis catheter exits the body. Characterized by redness, swelling, tenderness, and purulent drainage. Requires prompt treatment to prevent progression to tunnel infection or peritonitis.
