What condition may develop due to rapid fluid shifts in dialysis patients?

Disequilibrium syndrome is a condition that can arise due to rapid fluid and electrolyte shifts during dialysis. This syndrome occurs when there is a sudden change in the serum osmolality of the blood. During dialysis, excess fluid and waste products are removed from the bloodstream, which can lead to a rapid decrease in serum osmolality.

As a result, fluid may shift from the blood vessels into brain tissue, causing symptoms such as headache, nausea, vomiting, and in severe cases, seizures. These symptoms highlight the importance of closely monitoring fluid removal rates during dialysis sessions to minimize the risk of fluid shifts that can lead to this syndrome.

Other choices describe conditions that may not be directly related to the rapid changes in fluid balance seen in dialysis, such as pulmonary edema, which is typically caused by fluid overload rather than shifts, anemia, which results from factors like decreased erythropoietin production or iron deficiency, and ascites, which is related to conditions like cirrhosis or heart failure rather than dialysis itself. Understanding these distinctions helps clarify why disequilibrium syndrome is particularly associated with the rapid fluid shifts experienced by dialysis patients.
