How should the needles be positioned during dialysis treatment?

Placing the arterial needle near the anastomosis, and ensuring that it is no closer than 1.5 to 2 inches from it, is critical for effective dialysis treatment. This positioning allows for optimal access to the blood flow while minimizing damage to the vascular site. The goal is to ensure that the arterial needle is close enough to be effective while avoiding complications such as the development of pseudoaneurysms or other traumatic injuries to the access site, which could compromise future dialysis sessions.

Additionally, this practice maintains the integrity of the access site by preventing excessive trauma, allowing skin and tissues to heal properly after needle insertion.

The other options, while they contain relevant practices, do not focus specifically on the importance of the distance from the anastomosis or fail to provide the necessary detail required for safe and effective dialysis access management. Thus, option B accurately captures an essential aspect of needle positioning during dialysis treatment.
