The nurse cares for a client with a right-arm arteriovenous fistula (AVF) for hemodialysis treatments. Which nursing action is contraindicated?

A. Drawing blood from the left arm is appropriate and avoids compromising the AVF site. B. Wearing a watch on the left wrist poses no risk to the AVF in the right arm. C. Palpating for a "thrill" is a correct assessment technique to check AVF patency. D. Taking a blood pressure reading on the arm with an AVF is contraindicated because it can damage the fistula, reduce blood flow, or lead to thrombosis.
