Before open abdominal aneurysm repair, which baseline finding should be assessed?

• A. Peripheral pulses
• B. Lung sounds
• C. ABG values
• D. Blood glucose

Answer: (A)

The main idea is to assess distal arterial perfusion before a major vascular procedure. Establishing the status of peripheral pulses, especially in the lower extremities, gives a baseline measure of blood flow to the legs. This baseline is crucial because open abdominal aortic aneurysm repair can affect distal perfusion when the aorta is manipulated and the graft is placed. If postoperative checks show a change from this baseline—such as diminished or absent distal pulses—it can signal graft problems, emboli, or limb ischemia requiring prompt attention. While listening to lung sounds, checking ABG values, or monitoring blood glucose are important parts of preop assessment, they don’t provide the specific baseline needed to monitor perfusion to the legs after this vascular surgery.
