What should be avoided in the arm of a client with an AV shunt?

In a patient with an arteriovenous (AV) shunt, it is crucial to avoid both blood draws and blood pressure readings in that arm. The reason for this restriction lies in the function of the AV shunt, which is primarily used for dialysis access. The shunt indicates a site where an artery and vein have been surgically connected to facilitate hemodialysis.

Performing blood draws could lead to complications such as clotting or damage to the shunt, which could jeopardize the patient's access for any ongoing dialysis treatments. Likewise, taking blood pressure readings in the arm with an AV shunt can cause trauma to the shunt itself, potentially leading to vascular damage or compromising the function of the shunt. Additionally, measuring blood pressure can create excessive pressure, which may disrupt the delicate balance within the vascular system where the shunt facilitates blood flow.

Thus, both procedures should be meticulously avoided to ensure the integrity and functionality of the AV shunt and to prevent additional complications for the patient. This combination of avoidance is crucial for maintaining the shunt's viability for future treatments.
