The onset of an aortic aneurysm is typically described as which of the following?

• A. Abrupt
• B. Gradual
• C. Intermittent
• D. None of the above

Answer: (A)

An aortic aneurysm is usually silent until a rupture or acute dissection occurs, at which point symptoms begin suddenly. The rapid, catastrophic nature of rupture causes abrupt onset of severe chest, back, or abdominal pain, often with signs of shock from sudden blood loss. Because the event is sudden and dramatic, abrupt best describes the onset. Gradual or intermittent onset would imply slowly developing or waxing symptoms, which isn’t typical for a rupturing aneurysm. None of the above isn’t needed since abrupt fits the scenario.
