A nurse is monitoring a client following a hemodialysis treatment through an arteriovenous (AV) fistula. Which of the following findings should the nurse report to the provider?

A. Palpable thrill at the AV fistula access site: A palpable thrill over the AV fistula is an expected finding and indicates that the fistula is patent with adequate blood flow. This vibration confirms proper functioning of the vascular access for hemodialysis. B. Headache, restlessness: Headache and restlessness following hemodialysis can indicate a complication such as disequilibrium syndrome, which occurs due to rapid shifts in fluid and electrolytes. These neurological symptoms can progress and require prompt reporting and intervention to prevent worsening cerebral edema or other complications. C. Heart rate 65 bpm: A heart rate of 65 beats per minute is within normal limits for most adults. Unless the client has symptomatic bradycardia or other cardiac concerns, this finding does not require immediate intervention. D. Blood pressure 134/82 mm Hg: This blood pressure is slightly elevated but not uncommon post-dialysis due to fluid shifts or vascular tone changes. It does not indicate an acute complication requiring urgent provider notification.
