What best describes dialysis disequilibrium syndrome and the symptoms you monitor during dialysis initiation?

• A. A neurological complication from rapid solute removal causing cerebral edema; monitor for headache, nausea, vomiting, confusion, restlessness, and seizures.
• B. A cardiovascular event caused by rapid fluid overload; monitor for chest pain and dyspnea.
• C. An infection associated with catheter use; monitor for fever and catheter site redness.
• D. A metabolic alkalosis due to bicarbonate imbalance; monitor for dizziness and tingling.

Answer: (A)

Dialysis disequilibrium syndrome arises when rapid removal of solutes during dialysis lowers plasma osmolality faster than the brain adjusts, causing water to move into brain tissue and leading to cerebral edema. This neurologic disturbance is most likely to appear during dialysis initiation when clearance is fastest. Monitor for symptoms that reflect brain involvement: headache, nausea, vomiting, confusion or altered mental status, restlessness, and, in severe cases, seizures. These signs point to cerebral edema from the osmotic shift rather than to cardiovascular events, infection, or metabolic alkalosis. In contrast, chest pain or dyspnea would suggest a cardiovascular issue; fever or catheter-site redness suggests infection; dizziness and tingling would fit metabolic disturbances, not DDS.
