What is the normal target lab value range for BUN in dialysis patients?

1. 0-10 mg/dL

2. 5-25 mg/dL

3. 20-40 mg/dL

4. 30-50 mg/dL

The correct answer is: 5-25 mg/dL

The normal target lab value range for Blood Urea Nitrogen (BUN) in dialysis patients is typically between 5-25 mg/dL. This range is important as it indicates the effectiveness of the dialysis treatment in removing urea and other waste products from the blood. In patients with chronic kidney disease or those undergoing dialysis, BUN levels can help monitor the patient's overall metabolic state and the adequacy of dialysis. A level within this range suggests that the dialysis is performing well in clearing waste products, while levels outside of this range might indicate insufficient dialysis or other complications that need to be addressed. Values below 5 mg/dL may suggest undernutrition or a lack of protein intake, while levels higher than 25 mg/dL can indicate renal insufficiency or inadequate dialysis treatment, leading to an accumulation of urea in the blood. Thus, maintaining BUN levels within this target range is crucial for ensuring the health and well-being of dialysis patients.
