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?

Choice A rationale: Cantaloupe is high in potassium. Clients with acute kidney injury (AKI) have impaired potassium excretion, and consuming high-potassium foods increases the risk of hyperkalemia, which can lead to cardiac arrhythmias.

Choice B rationale: Baked potatoes contain significant potassium, especially in the skin. In AKI, potassium retention is dangerous, so this choice reflects poor understanding of dietary restrictions for renal safety.

Choice C rationale: Yogurt is rich in potassium and phosphorus. In AKI, both electrolytes may accumulate due to reduced renal clearance, making yogurt an inappropriate choice without close monitoring.

Choice D rationale: Pecans are low in potassium, making them a safer snack for clients with AKI. Choosing low-potassium foods demonstrates appropriate understanding of renal dietary management.

Choice A reason: Diabetes can increase the risk of infection, including peritonitis, due to immune system impairment.

Choice B reason: Obesity may contribute to surgical complications but is not directly linked to an increased risk of peritonitis in the context of peritoneal dialysis.

Choice C reason: Hemochromatosis can affect many organs but is not directly linked to an increased risk of peritonitis in peritoneal dialysis.

Choice D reason: Ulcerative colitis affects the colon and is not directly linked to an increased risk of peritonitis in peritoneal dialysis.
