Why is dextrose added to the dialysate?

• A. To increase dialysate osmolality
• B. To prevent hypoglycemia
• C. To improve color
• D. To provide lubrication

Answer: (B)

Dextrose in the dialysate provides a glucose source for the patient during dialysis. As the blood passes through the dialysis circuit, glucose can be lost or its blood level can drop, so having glucose in the dialysate allows glucose to diffuse into the bloodstream, helping prevent hypoglycemia and giving the patient needed energy during the treatment. While dextrose does raise dialysate osmolality a bit, the primary reason for adding it is to prevent low blood sugar, not to change color or provide lubrication.
