What are classic signs of abdominal aortic aneurysm (AAA)?

1. Sudden onset of fever, chills

2. Sharp back pain, unexplained groin pain

3. Persistent cough, elevated white blood cell count

4. Elevated heart rate, increased blood pressure

The correct answer is: Sharp back pain, unexplained groin pain

The classic signs of an abdominal aortic aneurysm (AAA) are often related to the characteristics of the aneurysm's growth or rupture. Sharp back pain and unexplained groin pain are significant indicators because they occur due to the pressure the enlarged aorta places on surrounding nerves and structures. The back pain is typically described as a deep, aching sensation, while groin pain can arise from irritation of nearby anatomical structures or from vascular compromise, highlighting the emergent nature of this clinical presentation. In contrast, the other options do not align with the classic signs of AAA. Sudden onset of fever and chills may suggest an infectious process or inflammation, which is not characteristic of AAA. A persistent cough and elevated white blood cell count are more related to respiratory or infectious issues rather than vascular problems. Lastly, while elevated heart rate and increased blood pressure can occur in various conditions, they do not specifically indicate AAA and are not among the recognized classic symptoms. Understanding these characteristic signs is crucial for timely diagnosis and intervention in the case of an AAA.
