Question 5 of 5
A nurse is assessing a client's arteriovenous (AV) fistula. Which finding provides evidence of its normal function?
Correct Answer: A
Rationale: An enlarged vein is a normal finding in a functioning arteriovenous (AV) fistula, indicating adequate blood flow and patency. An AV fistula, used for dialysis, relies on arterialization of the vein, which causes it to dilate and thicken over time. Placelessness (likely a typo for 'pulselessness') suggests occlusion, redness may indicate infection, and an ecchymotic area points to trauma or bleeding—none of which are normal. The enlarged vein, often accompanied by a palpable thrill or audible bruit, confirms the fistula is working properly and ready for dialysis access.
