Certified Hemodialysis Technician Practice Exam 2025 – All-in-One Guide to Exam Success

Blood urea nitrogen (BUN) is an important parameter monitored in patients undergoing dialysis, as it reflects the balance between protein intake and protein metabolism, as well as kidney function. In the context of dialysis patients, a normal range for BUN levels is typically considered to be between 10 to 20 mg/dL. This range indicates that the body is adequately clearing waste products, including urea, during the dialysis process.

When BUN levels are within this range, it suggests that the dialysis treatment is effective in removing nitrogenous waste from the blood. Higher levels could indicate inadequate dialysis or increased protein breakdown, while significantly lower levels might suggest other metabolic issues or excessive dialysis.

This established normal range is crucial for dialysis technicians and healthcare providers to monitor because it guides adjustments in treatment plans, dietary recommendations, and overall patient management. Reliable monitoring of BUN levels helps to ensure that dialysis patients maintain their health and well-being.
