What is an important discharge instruction for a patient with an arteriovenous shunt?

1. Keeping the operative arm elevated for several days

2. Checking blood pressure in the operative arm

3. Keeping the operative arm dependent for several days

4. Maintaining a pressure dressing over the site

The correct answer is: Keeping the operative arm elevated for several days

Keeping the operative arm elevated for several days is a critical discharge instruction for a patient with an arteriovenous shunt. Elevation of the arm helps to reduce swelling and promotes venous return, which can be particularly beneficial following surgical procedures where an arteriovenous shunt is established. This instructional practice not only aids in minimizing discomfort but also supports optimal healing of the site. While other discharge instructions may be relevant in different contexts, they do not address the specific needs associated with the care of an arteriovenous shunt after surgery. For instance, checking blood pressure in the operative arm may not be advisable as frequent BP checks can affect blood flow through the shunt, potentially leading to thrombosis or other complications. Keeping the operative arm dependent could increase the risk of swelling and impede healing, while maintaining a pressure dressing over the site would typically be relevant only for a limited time post-surgery, primarily to control bleeding rather than as a long-term care strategy. Therefore, the focus on elevation is paramount and aligns with best practices for ensuring a healthy recovery process.
