What statement indicates that a client’s wife needs further teaching regarding care of an arteriovenous fistula?

The statement that indicates the client's wife needs further teaching is the one concerning taking blood pressure in the arm with the fistula. Understanding the importance of protecting the arteriovenous fistula is crucial for maintaining its function and preventing complications.

Taking blood pressure in the arm that has the fistula can pose a significant risk. It may compromise the fistula's integrity, potentially leading to changes in blood flow or even causing thrombosis. Therefore, healthcare providers instruct patients to avoid using the arm with the fistula for blood pressure measurements, venipuncture, or any invasive procedures to preserve the fistula for dialysis access.

The other statements reflect appropriate care and understanding of the arteriovenous fistula. Regularly feeling for the bruit allows for monitoring of the fistula's patency, while being cautious at night helps prevent accidental injury to the arm. Checking for signs of redness and swelling ensures any potential complications can be addressed promptly, promoting the fistula's health and function.
