Dialysis Technician Practice Exam

During dialysis, the levels of waste in the blood should ideally:

1. Increase

2. Stay the same

3. Decrease

4. Fluctuate

The correct answer is: Decrease

During dialysis, the primary goal is to remove waste products and excess fluids from the blood in order to prevent toxicity and maintain a balanced biochemical environment. The procedure typically involves the use of a dialysis machine, which facilitates the diffusion of waste products from the blood into the dialysis solution, leading to a reduction in the levels of these harmful substances. When functioning effectively, dialysis should result in a significant decrease in blood urea nitrogen (BUN) and creatinine levels, both of which are important indicators of kidney function and overall metabolic waste accumulation. Therefore, as dialysis progresses, patients should observe a measurable decline in the concentration of these waste products in their blood. This decrease is essential for the patient's health, enabling them to manage the consequences of kidney failure effectively. Stability in waste levels or an increase would suggest inadequate dialysis treatment, which could lead to serious health complications. Consequently, ensuring a decrease in waste levels during dialysis is a critical aspect of patient monitoring and treatment effectiveness.
