Chest pain caused by a thoracic aortic aneurysm typically radiates to which area?

1. left arm

2. back

3. epigastric region

4. right shoulder

The correct answer is: back

Chest pain associated with a thoracic aortic aneurysm typically radiates to the back. This is due to the anatomical position of the aorta in relation to the spine and other structures in the thorax. When an aortic aneurysm develops or expands, it can put pressure on surrounding tissues and nerves, leading to pain that is often described as a severe, tearing sensation that can be felt in the back. The description of the pain as radiating to the back is important for healthcare providers to consider because it can help differentiate thoracic aortic aneurysm from other causes of chest pain, such as myocardial infarction or musculoskeletal pain, which often have different radiation patterns. Recognizing this pattern can guide further diagnostic testing and appropriate care for patients presenting with chest pain.
