A nurse is assessing a client who has an arteriovenous (AV) graft in the left forearm. Which of the following findings should indicate to the nurse a complication of vascular access?

A. Dilated appearance of the AV site: A dilated appearance of the AV site is not necessarily a complication. Some dilation may be expected as the graft matures. However, significant or sudden dilation could indicate an issue, such as stenosis or a developing clot, which should be assessed further. B. Absence of a bruit: The absence of a bruit over an arteriovenous graft is a sign of a potential complication, such as thrombosis or a blockage in the graft. The bruit indicates proper blood flow through the graft. Its absence suggests a lack of blood flow, which requires immediate attention. C. 2+ left radial pulse: A 2+ pulse is considered normal and indicates adequate peripheral circulation. It does not suggest a complication related to the AV graft. D. Presence of a palpable thrill: A palpable thrill is typically a normal finding when assessing an AV graft. It is the vibration felt over the graft site due to blood flow and indicates that the graft is functioning properly.
