A nurse is assessing a client following hemodialysis. Which of the following findings indicates dialysis disequilibrium?

A. Elevated temperature is not a typical sign of dialysis disequilibrium. Fever suggests infection (e.g., access-site infection or bacteremia), not fluid shifts. B. Malaise is nonspecific and not a classic symptom of dialysis disequilibrium. It is common after dialysis due to fatigue, fluid shifts, and electrolyte changes. C. Headache is a common symptom of dialysis disequilibrium syndrome, caused by rapid changes in fluid and solute balance during dialysis. Indicates increased intracranial pressure from cerebral edema. Requires immediate assessment and provider notification. D. Nosebleed is not associated with dialysis disequilibrium. It suggests platelet dysfunction, anticoagulation effects, or hypertension.
