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

A. Radial pulse distal to AVF is absent and ulnar pulse is present: The presence of a palpable ulnar pulse suggests some distal perfusion remains. While changes in distal pulses should be monitored, this finding alone may not indicate an acute complication requiring immediate reporting. B. Bruising at the AVF site is purple and green in color: Minor bruising can occur after fistula creation and is typically expected during healing. Unless accompanied by swelling, pain, or signs of hematoma expansion, it does not necessitate immediate reporting. C. Descriptions of numbness and tingling in fingers distal to the AVF: Numbness and tingling may indicate ischemia or compromised circulation distal to the fistula, a serious complication that requires prompt evaluation by the healthcare provider to prevent tissue damage. D. A loud and consistent bruit is auscultated at the AVF site: A palpable thrill and auscultated bruit are normal findings indicating proper fistula function. Continuous monitoring is necessary, but this finding does not require reporting if consistent and expected.
