What is the most appropriate immediate nursing intervention? ## 보기 1. Increase the dwell time of the dialysate to improve clearance 2. Irrigate the peritoneal catheter with normal saline 3. Continue the dialysis cycle and monitor vital signs 4. Stop the dialysis immediately and notify the healthcare provider **✔ 정답** **정답: 4** ## 해설 Cloudy dialysate with pain and fever signals peritonitis, an emergency requiring immediate dialysis cessation and provider notification. Continuing dialysis could worsen infection. ## 심화 해설 Clinical Presentation and Pathophysiology The client’s triad of cloudy dialysate, abdominal pain, and fever is the classic presentation for peritoneal dialysis (PD)-associated peritonitis. This condition represents a serious infection of the peritoneal cavity, most commonly caused by bacterial contamination, and is associated with substantial morbidity, mortality, and technique failure [1,2]. The cloudiness of the effluent is due to an elevated white blood cell count, typically with a predominance of polymorphonuclear neutrophils, indicating an active inflammatory response within the peritoneal membrane. Rationale for Immediate Intervention The most appropriate immediate nursing intervention is to stop the dialysis immediately and notify the healthcare provider. When peritonitis is suspected, the priority is to halt the instillation of fresh dialysate into an infected peritoneal cavity. Continuing the dialysis cycle, even for a short period, can dilute the local immune response, exacerbate inflammation, and potentially contribute to systemic sepsis [1,2]. The International Society for Peritoneal Dialysis (ISPD) guidelines emphasize that management of a peritonitis episode must be swift and appropriate to minimize morbidity, and the first step in the clinical setting is to recognize the emergency and prepare for diagnostic and therapeutic interventions under a provider’s direction [1,2]. Analysis of Incorrect Options - Option 1 (Increase dwell time): Increasing the dwell time is contraindicated. Prolonging the exposure of the peritoneal membrane to a contaminated solution will worsen the infection and inflammation, increasing patient discomfort and the risk of systemic complications . - Option 2 (Irrigate with normal saline): Routine irrigation of the catheter is not a standard or recommended intervention for suspected peritonitis. Unnecessary manipulation of the catheter and infusion of fluid can introduce new pathogens or mechanically disrupt the peritoneal membrane, worsening the infection. The priority is to obtain a sample of the cloudy effluent for culture and cell count, not to flush the system . - Option 3 (Continue dialysis and monitor): Continuing the dialysis cycle is a critical error. It delays definitive diagnosis and treatment, allowing the infectious process to progress. Peritonitis is the most common reason for transfer from PD to hemodialysis, and a delay in management directly contributes to technique failure and increased hospitalization events [1,2]. Clinical Significance and Nursing Implications PD-associated peritonitis is a time-sensitive emergency. The nurse’s role is to recognize the hallmark signs, immediately discontinue the dialysis exchange, and secure a sample of the cloudy dialysate effluent for laboratory analysis (cell count with differential, Gram stain, and culture) before any antibiotics are administered . The nurse must then prepare to support the healthcare provider with the initiation of empiric antibiotic therapy, typically administered intraperitoneally, as per unit protocol and ISPD guidelines. Prompt recognition and cessation of the exchange are key measures that directly impact patient outcomes, including the preservation of the peritoneal catheter and the continuation of PD as a renal replacement therapy modality [1,2]. ## 임상 시나리오 Recognizing & Responding to PD PeritonitisImmediate nursing action for cloudy effluent, pain, and fever The classic triad of cloudy dialysate, abdominal pain, and fever indicates peritoneal dialysis-associated peritonitis. The cloudiness results from an elevated white blood cell count (predominantly neutrophils). The priority intervention is to stop the dialysis immediately and notify the healthcare provider. Continuing the cycle dilutes the local immune response and risks systemic sepsis. Management must follow ISPD guidelines for rapid diagnosis and treatment. CautionDo not increase dwell time, irrigate the catheter, or simply monitor. Save the cloudy effluent bag for cell count, Gram stain, and culture as ordered. ## 핵심 개념 - **CAPD** — Continuous Ambulatory Peritoneal Dialysis; a form of PD using gravity to fill and drain dialysate without a machine. - **Peritonitis** — Inflammation of the peritoneum, often infectious, presenting with cloudy effluent, abdominal pain, and fever in PD patients. - **Cloudy Dialysate** — Effluent with elevated white blood cells (>100 cells/µL, >50% neutrophils), the hallmark sign of PD-related peritonitis. - **ISPD Guidelines** — International Society for Peritoneal Dialysis recommendations for prompt diagnosis and management of PD-related infections. - **Dwell Time** — The period dialysate remains in the peritoneal cavity; prolonging it during infection is contraindicated. ## 같은 주제 문제 - [A nurse is caring for a client who has been receiving peritoneal dialysis for 6 months.
