A nurse is caring for a client who has chronic kidney failure. The client received hemodialysis 1 hr ago. The nurse should identify that which of the following findings is a manifestation of a complication related to the procedure?

Hemodialysis is used in chronic kidney failure to remove excess fluid, waste products, and electrolytes from the blood when the kidneys can no longer perform these functions effectively. Although it is life-sustaining, complications can occur during or shortly after the procedure, including hypotension, disequilibrium syndrome, bleeding, and neurological changes. Nurses must carefully assess for early signs of post-dialysis complications to prevent serious outcomes. Changes in neurological status after dialysis require immediate attention. A. A palpable thrill at the fistula site is an expected and desirable finding in a client with an arteriovenous fistula used for hemodialysis access. It indicates that blood is flowing properly through the fistula and confirms patency. Absence of a thrill would be concerning, but its presence is normal and not a complication. B. Hyperglycemia is not a common direct complication immediately related to hemodialysis. Post-dialysis complications are more commonly associated with fluid shifts, electrolyte changes, and vascular access issues rather than sudden increases in blood glucose. Therefore, this is not the priority finding associated with the procedure. C. Altered mental status may indicate dialysis disequilibrium syndrome, a serious complication caused by rapid shifts in fluid and solute levels during or after hemodialysis. Symptoms can include headache, nausea, confusion, restlessness, seizures, and decreased level of consciousness. Because neurological changes can signal cerebral edema, this finding requires prompt recognition and intervention. D. A decrease in weight is an expected finding after hemodialysis because excess fluid is removed from the body during the procedure. Weight loss reflects successful fluid removal and helps evaluate treatment effectiveness. It is not considered a complication unless accompanied by signs of excessive fluid loss or hemodynamic instability.
