An aneurysm is present when

An aneurysm is present when

• A. The wall of a blood vessel is weakened
• B. The heart muscle is enlarged
• C. The blood vessel is blocked
• D. The blood pressure is low

Answer: (A)

An aneurysm is a localized dilation of a blood vessel caused by a weakened wall, allowing it to bulge outward under the pressure of blood. This describes the vessel wall becoming structurally fragile and expanding, which is what defines an aneurysm. It’s not about the heart muscle enlarging, which is a different condition affecting the heart itself; nor about a vessel that is blocked, which implies reduced or stopped blood flow; nor about low blood pressure, which is a systemic state not specific to wall weakening and dilation.
