Final answer:
The nurse should report cloudy dialysate effluent to the provider because it could indicate a serious infection in a CKD patient receiving peritoneal dialysis.
Step-by-step explanation:
The question pertains to a client with chronic kidney disease (CKD) who is undergoing peritoneal dialysis (PD). Among the findings listed, the nurse should report cloudy dialysate effluent to the provider. Cloudy dialysate is considered an abnormal finding and can indicate an infection, such as peritonitis, which is a medical emergency when it comes to patients on peritoneal dialysis. Greater outflow than inflow could simply mean effective drainage, while weight loss might be expected due to fluid removal. Pain during inflow may happen occasionally, but it is not as immediately concerning as a potential infection signified by cloudy effluent.
