Dialysis Technician Practice Exam

What is a common complication associated with hemodialysis?

1. Dehydration

2. Hypertension

3. Hypotension

4. Hyperkalemia

The correct answer is: Hypotension

Hypotension is a common complication associated with hemodialysis due to the rapid removal of fluid from the bloodstream. During the dialysis process, excess fluid is filtered out to cleanse the blood, which can lead to a significant drop in blood volume. This decrease in volume can cause blood pressure to fall, leading to hypotension. Other factors that can contribute to this condition during dialysis include the presence of certain medications, the patient's individual tolerance to fluid removal, and the setting of ultrafiltration rates. Managing hypotension in dialysis patients is critical, as it can lead to symptoms such as dizziness, fainting, and in severe cases, complications like cardiovascular stress. Understanding this complication is essential for dialysis technicians, as they need to monitor patients closely during treatments and implement strategies to prevent or address hypotension when it arises.
