The clinic practical nurse performs a physical examination on Mr. Fredericks. Which finding would support the diagnosis of an abdominal aortic aneurysm (AAA)?

• A. Epigastric discomfort
• B. Pyrosis
• C. Abdominal bruit
• D. Tearing abdominal pain

Answer: (C)

An abdominal bruit reflects turbulent blood flow in a widened abdominal aorta, which fits with an abdominal aortic aneurysm. When the aorta enlarges, blood moves through the vessel in a chaotic way, producing sounds you can hear with a stethoscope as a vascular bruit over the abdomen. This finding directly points to abnormal flow in the abdominal aorta and helps support the diagnosis of AAA. Epigastric discomfort is nonspecific and can arise from many GI conditions. Pyrosis is heartburn from reflux and does not indicate aneurysm. Tearing abdominal pain points more toward aortic dissection, a different and more acutely dangerous process than a simple aneurysm. In practice, a pulsatile abdominal mass can be a clue to AAA too, but a bruit is specifically about abnormal flow within the vessel and how you would detect it on exam.
