What is an aneurysm?

  1. Blood clot in the lungs

  2. Blood vessel inflammation

  3. Ruptured blood vessel leading to massive hemorrhage

  4. Vein enlargement

The correct answer is: Ruptured blood vessel leading to massive hemorrhage

An aneurysm is defined as an abnormal enlargement or bulging in the wall of a blood vessel, often occurring in arteries. This condition arises when the pressure of blood flow causes a weakened area of the vessel wall to expand. While the serious consequence of an aneurysm can be a rupture, which indeed leads to massive hemorrhage, the term itself describes the condition of vessel enlargement. In the context of the other choices, a blood clot in the lungs refers to a pulmonary embolism, which is unrelated to the definition of an aneurysm. Blood vessel inflammation is known as vasculitis, which also does not correspond to the characteristics of an aneurysm. Vein enlargement refers more specifically to conditions like varicose veins and does not capture the concept of a bulging artery, which is central to understanding aneurysms. Therefore, the most accurate choice relating to the definition and implications of an aneurysm is the option that describes a ruptured blood vessel leading to massive hemorrhage, highlighting a critical complication that can arise from this condition.
