During an admission assessment, which clinical finding should a nurse expect with an abdominal aortic aneurysm diagnosis?

A pulsating abdominal mass is a classic clinical finding associated with an abdominal aortic aneurysm. This occurs due to the abnormal dilation of the aorta, which can create a bulge that can often be felt as a mass in the abdomen. As the aneurysm enlarges, the increased pressure and turbulence of blood flow make the mass palpable, often leading to a distinct, rhythmic pulsation that mirrors the heartbeat.

Other symptoms may present in different contexts but are not as definitive in identifying an abdominal aortic aneurysm. Severe abdominal pain typically indicates potential complications such as rupture or dissection, but it is not a universal finding in all patients with an aneurysm. Nausea and vomiting can arise from numerous gastrointestinal issues, and weight loss might occur over time but is not a direct symptom of an abdominal aortic aneurysm. Therefore, the presence of a pulsating abdominal mass is the indicator that most directly correlates with this condition.
