The nurse is providing care to a client who is 12 hours post-abdominal aortic aneurysm (AAA) repair. Which assessment finding by the nurse would indicate a possible complication?

1. Urinary output 360 mL since surgery
2. Temperature 100.2 degrees F (37.9 degrees C)
3. 2+/4+ pedal pulses
4. Mean arterial pressure 50

A mean arterial pressure of 50 after an abdominal aorta aneurysm repair indicates potential complications, as it is below the normal MAP range and could result in inadequate organ perfusion.

Explanation:

The fourth option, a mean arterial pressure (MAP) of 50, would indicate a possible complication in a patient 12 hours post abdominal aorta aneurysm (AAA) repair. A normal MAP is typically between 70 and 110 mmHg and a MAP of less than 60 mmHg is generally considered inadequate to maintain tissue perfusion. A MAP of 50 suggests hypotension, which could lead to inadequate organ perfusion postoperatively, possibly indicating complications such as bleeding, cardiac issues, or poor fluid management.
