DaVita In-Center Hemodialysis (ICHD) Nurse/PCT Practice Test

Hypotension is a common complication associated with hemodialysis due to a variety of factors related to the procedure. During hemodialysis, fluid is removed from the patient's blood to reach a target weight, which can lead to a rapid decrease in blood volume. This acute shift can result in lowered blood pressure, especially if too much fluid is removed too quickly or if the patient has underlying conditions that affect their blood volume regulation.

Patients undergoing hemodialysis are often on fluid restrictions and may have residual kidney function affecting their volume status. As fluids are drawn off through the dialysis machine, the body may not be able to compensate enough, leading to symptoms such as dizziness, weakness, or fainting. Monitoring blood pressure during the treatment is critical to prevent hypotension and manage it effectively if it occurs.

Understanding the dynamics of fluid removal during dialysis helps in recognizing the risk factors and in managing treatment protocols to minimize this complication, ensuring patient safety and comfort.
