Final answer:
Manifestations of an occluded abdominal aorta graft include reduced blood flow leading to hypoxia in tissues, which can cause cyanotic areas in the lower extremities. A nurse should expect to find irregularly shaped cyanotic areas in the legs of a patient with a suspected graft occlusion.
Step-by-step explanation:
The symptoms associated with an occlusion of a graft in the abdominal aorta are related to the blockage of blood flow to areas of the body supplied by that artery. When a graft becomes occluded, or blocked, it can lead to decreased blood flow and consequently an insufficient oxygen supply (hypoxia) to the tissues beyond the occlusion. Of the options provided by the student, the manifestation that the nurse should expect is 'D. Lower extremities have
irregularly shaped cyanotic areas.' This occurs due to the reduced delivery of oxygenated blood to the tissues, causing them to appear blue or purplish (cyanosis). Increased abdominal girth may suggest aneurysm or other conditions, while a bounding pedal pulse is unlikely because the pulse would generally be decreased or absent due to poor circulation. Increased urinary output (UO) is not directly related to aortic graft occlusion.
