What is an expected outcome of proper needle site rotation in dialysis grafts?

Increased likelihood of infection
Reduced risk of pseudoaneurysm
Heightened pain sensation
Worsened blood flow

The correct answer is: Reduced risk of pseudoaneurysm

Proper needle site rotation in dialysis grafts is crucial for maintaining the health and longevity of the access site. When the needles are inserted into different areas of the graft during each dialysis session, it helps to distribute the trauma that occurs to the blood vessel walls. This practice significantly reduces the risk of pseudoaneurysm formation, which is a local dilation of the vessel that can occur due to repeated trauma in the same area. By rotating the needle sites, the body has a chance to heal itself between sessions, minimizing the development of scar tissue and allowing better blood flow through the graft. This not only preserves the integrity of the vascular access but also enhances overall patient outcomes by ensuring that the access remains functional for future treatments. Therefore, the expected outcome of proper needle site rotation is a reduced risk of pseudoaneurysm.
