Which finding for a client with an arteriovenous fistula (AV Fistula) should the practical nurse (PN) report to the healthcare provider?

The correct answer is choice A: Descriptions of numbness and tingling in fingers distal to the AVF. Choice A rationale: Descriptions of numbness and tingling in fingers distal to the arteriovenous fistula (AVF) suggest possible nerve compression or impaired blood flow, which are concerning findings. These symptoms could indicate reduced perfusion to the distal extremities and require immediate attention to prevent further complications. Choice B rationale: A loud and consistent bruit auscultated at the AVF site is an expected finding and indicates adequate blood flow through the fistula. A bruit is the sound of turbulent blood flow and is commonly heard over functional AV fistulas. Choice C rationale: Bruising at the AVF site is a common occurrence after the creation of the fistula. It is expected due to the surgical intervention and the manipulation of blood vessels. As long as the bruising is not severe or accompanied by other concerning symptoms, it does not need immediate reporting. Choice D rationale: The absence of the radial pulse distal to the AVF and the presence of the ulnar pulse are normal findings in a functioning AV fistula. The AV fistula diverts blood flow away from the radial artery, leading to a diminished pulse. This is not a cause for concern as long as the ulnar pulse is present, indicating adequate perfusion to the hand.
