5. The nurse is caring for a client on the first postoperative day following a surgical repair of an abdominal aortic aneurysm. Which nursing diagnosis is the most important for this client?

Correct answer: C

Rationale: Peripheral tissue perfusion is a major concern in the postoperative period following an abdominal aneurysm repair. Peripheral pulses should be checked frequently during the first 24 hours. A weak or absent pulse may be a sign of embolization or graft closure, especially if accompanied by a pale, cold, mottled extremity; the nurse should immediately report this to the surgeon. Risk for infection, deficient knowledge, and activity intolerance are all important nursing diagnoses in the postoperative period, but peripheral tissue perfusion is the most immediate concern.
