Final answer:
An abdominal bruit is the assessment data that would support the diagnosis of an abdominal aortic aneurysm (AAA), as it indicates turbulent blood flow caused by the aneurysm.
Step-by-step explanation:
The correct assessment data that a nurse would recognize to support the diagnosis of an abdominal aortic aneurysm (AAA) is b. Abdominal bruit. This is because an AAA can create a turbulent blood flow that leads to a bruit, which is a sound heard over an artery due to abnormal blood flow. While ripping abdominal pain may sometimes be associated with AAA, especially if it is leaking or rupturing, an abdominal bruit is a more direct indicator and may be detected in a physical exam. Options a, shortness of breath, and d, decreased urinary output, are less specifically related to AAA and could indicate other health issues. Furthermore, abdominal ultrasound is a diagnostic tool commonly used to visualize the size and shape of an aortic aneurysm and confirm its presence.
