Which symptom pattern is characteristic of an acute aortic dissection?

• A. Fever and cough
• B. Productive cough with chest pain
• C. Abrupt tearing pain migrating to the back
• D. Gradual dull abdominal pain

Answer: (C)

Acute aortic dissection is suggested by sudden, severe chest or back pain that patients often describe as tearing or ripping, and it may move or migrate as the false lumen extends along the aorta. This abrupt, intensely painful pattern happens because blood forces its way between the layers of the aortic wall, creating a dissection that can propagate upstream or downstream, causing the pain to shift toward the back or between the shoulder blades.

This presentation stands in contrast to the other patterns: fever and cough point toward infection such as pneumonia; a productive cough with chest pain suggests a pulmonary process rather than a vascular one; and gradual dull abdominal pain indicates a non-acute abdominal issue. The key clue here is the abrupt onset of tearing pain with potential radiating back involvement, signaling a high-stakes vascular emergency that requires immediate assessment and management.
