What observation should you report to the registered nurse when caring for a patient with a peritoneal dialysis catheter?

In the context of caring for a patient with a peritoneal dialysis catheter, observing purulent drainage is significant and should be reported to the registered nurse. Purulent drainage typically indicates an infection, which is a serious complication in patients with indwelling catheters. This type of drainage is characterized by its thick, cloudy appearance, often accompanied by foul odor, and may contain pus, signaling the presence of bacteria or other pathogens. Reporting this observation is critical because timely intervention can prevent further complications, such as peritonitis or systemic infection.

Clear drainage is generally expected and often considered normal, while serous drainage may also be harmless unless accompanied by other concerning symptoms. Blood-stained drainage could indicate trauma or other issues needing evaluation, but purulent drainage is more immediately alarming due to its direct association with infection risks. Effective communication about such findings supports the ongoing safety and health of the patient.
