If the dialysate solution contains too little sodium, which of the following symptoms may occur in a patient undergoing dialysis?

When the dialysate solution contains insufficient sodium, it can lead to a condition known as hyponatremia, which can result in hypotension, or low blood pressure. Sodium plays a crucial role in maintaining blood volume and pressure by regulating fluid balance within the body. When sodium levels drop, there is a decrease in blood volume, which can lead to decreased perfusion of organs and systems, ultimately causing hypotension during the dialysis process.

Other symptoms associated with low sodium levels—such as cramping, profound thirst, and headache—while they may occur in certain situations, are not the primary symptoms directly associated with the acute effects of inadequate sodium in the dialysate during dialysis treatment. These symptoms can often arise from different underlying causes or imbalances but are less specific to the immediate physiological responses seen with low sodium in dialysate.
