Aortic aneurysm is described as?

• A. Rupture of a plaque causing thrombus
• B. Weakened area of the aortic wall dilates
• C. Blockage of a coronary artery
• D. Inflammation of arteries

Answer: (B)

An aneurysm is a localized dilation of an artery caused by weakness in the arterial wall. In the aorta, this means a section of the wall loses strength and balloons outward. That description matches the concept of an aortic aneurysm: a weakened area that dilates.

The other descriptions refer to different problems: plaque rupture causing thrombus is related to acute coronary or peripheral vessel events, not a dilation; blockage of a coronary artery describes a heart attack; inflammation of arteries describes arteritis. In practice, an aneurysm may be asymptomatic until it ruptures, which is a medical emergency requiring rapid transport and supportive care.
