What complication may arise from rapid fluid removal during hemodialysis?

Rapid fluid removal during hemodialysis can lead to hypotension, which is characterized by a significant drop in blood pressure. This occurs because the sudden removal of excess fluid reduces the total blood volume, which can result in decreased venous return to the heart and subsequently lower cardiac output. Consequently, the body struggles to maintain adequate blood pressure, leading to symptoms such as dizziness, fainting, and weakness.

In the context of hemodialysis, managing fluid removal rates is critical to prevent this complication, as the patient's hemodynamic status must be closely monitored. Although hypotension is a common and recognizable risk of rapid fluid removal, the other options, while they represent potential concerns in different contexts, do not directly relate to the immediate effects of rapid fluid removal during dialysis. By focusing on the intricate balance of fluid and hemodynamics in dialysis settings, it becomes clear why hypotension is a primary concern in this situation.
