Which risk factor should the nurse focus on when teaching a patient who has a 5-cm abdominal aortic aneurysm?

Rationale: A. Abdominal trauma history: While abdominal trauma can cause acute vascular injury, it is not considered a major contributing factor to the development or progression of an abdominal aortic aneurysm (AAA). AAAs are primarily related to chronic vascular changes rather than isolated trauma events. B. Uncontrolled hypertension: Elevated blood pressure increases stress on the arterial wall, accelerating dilation and risk of rupture in an aneurysm. Controlling hypertension is a key teaching focus for clients with AAA to reduce life-threatening complications. C. Turner syndrome: Turner syndrome is associated with congenital cardiovascular abnormalities, such as coarctation of the aorta or bicuspid aortic valve, but it is not a primary risk factor for abdominal aortic aneurysm formation. D. Male gender: Being male increases the likelihood of developing an AAA, but gender is a nonmodifiable risk factor. Education should focus on modifiable factors, such as blood pressure control, which have a direct impact on aneurysm progression and rupture risk.
