What is the desired outcome when a patient performs fistula exercises?

• A. Enlargement of the vein
• B. Decrease in blood flow
• C. Thickening of arterial wall
• D. No change in fistula

Answer: (A)

Fistula exercises are done to enlarge the vein used for dialysis. When an arteriovenous fistula is created, the vein is exposed to higher arterial pressure and flow. Regular hand exercises promote increased blood return and shear stress on the vein walls, encouraging dilation and remodeling so the vein becomes larger and easier to cannulate. This helps with successful dialysis access maturation and better long-term function. Enlarging the vein is the main goal; decreased flow or thickening of the artery would not be desirable outcomes, and no change would not improve the access.
