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. A dilated appearance of the AV graft site can be expected due to the high-pressure blood flow between the artery and vein. B. The absence of a bruit indicates a complication—likely occlusion or thrombosis of the graft. A bruit (whooshing sound) is normally heard over a functioning AV graft due to turbulent blood flow. C. A 2+ radial pulse is normal and does not indicate a complication related to the graft. D. A palpable thrill (vibration felt over the graft) is an expected finding and indicates patency of the vascular access.
