A nurse is caring for a client who is receiving peritoneal dialysis. The nurse should monitor the client for which of the following manifestations of peritonitis?

A. Bradycardia: Bradycardia is not a typical manifestation of peritonitis in clients receiving peritoneal dialysis. Peritonitis usually presents with systemic signs of infection rather than isolated changes in heart rate, and bradycardia is more likely related to cardiac or medication issues. B. Hyperactive bowel sounds: Hyperactive bowel sounds are not commonly associated with peritonitis. Clients with peritonitis often experience abdominal tenderness and decreased bowel motility due to inflammation, making hyperactive sounds an unlikely finding. C. Nausea and vomiting: Nausea and vomiting are common signs of peritonitis in peritoneal dialysis patients. The infection of the peritoneal cavity can cause gastrointestinal upset, abdominal pain, and systemic symptoms such as fever, making close monitoring essential for early detection and treatment. D. Increased urinary output: Peritonitis does not cause increased urinary output. Changes in urine output are more commonly associated with kidney function status or fluid balance rather than infection of the peritoneal cavity.
