A nurse is caring for a client who has undergone hemodialysis. Which of the following findings should the nurse report to the provider?

A. Decrease in weight: A reduction in weight after hemodialysis is expected due to removal of excess fluid. This finding indicates the procedure is effectively managing fluid overload and does not require immediate reporting. B. Headache: Headaches can indicate rapid shifts in fluid and electrolytes during or after dialysis, sometimes signaling dialysis disequilibrium syndrome or other complications. Prompt reporting allows timely assessment and intervention to prevent worsening neurological symptoms. C. Fatigue: Mild fatigue is common following hemodialysis due to fluid shifts and changes in blood pressure. This is typically self-limiting and expected, so it does not require urgent reporting. D. Vibration at fistula site: A palpable thrill or vibration at the arteriovenous fistula is expected and indicates patency. This is a normal finding and does not warrant reporting to the provider.
