What is the initial nursing action for a client in peritoneal dialysis who reports nausea and diarrhea?

• A. Check blood pressure
• B. Collect the fluid from peritoneal catheter and send for culture
• C. Administer an antacid
• D. Ensure the drainage bag is positioned correctly

Answer: (B)

The initial nursing action for a client in peritoneal dialysis who reports nausea and diarrhea should focus on assessing the patient's condition and monitoring for any potential complications. Collecting the fluid from the peritoneal catheter and sending it for culture is an essential step to determine if there is an infection, such as peritonitis, which is a serious complication associated with peritoneal dialysis. Symptoms like nausea and diarrhea could indicate such an infection or other complications, making it critical to obtain a culture for accurate diagnosis and treatment.

The other options may provide relief or information but do not address the possibility of a serious underlying issue. Checking blood pressure can help assess the patient's hemodynamic status but wouldn’t directly address the potential cause of the symptoms. Administering an antacid may relieve gastrointestinal discomfort but doesn’t investigate or treat the underlying cause. Ensuring the drainage bag is positioned correctly is important for effective dialysis, but it does not directly address the new and potentially serious symptoms the patient is experiencing. Thus, obtaining and analyzing the fluid is the most clinically relevant action to ensure the patient's safety and appropriate care.
