Adult Health (AH) II Exam 1 Practice Test

The main idea is recognizing injuries to the major vessels, especially the aorta, in chest trauma. Aortic disruption or great vessel injury is a high-stakes vascular injury that can occur with blunt, high-energy chest trauma and rapid deceleration. It carries a high risk of rapid exsanguination, so it’s critical to identify promptly. In practice, mechanisms like heavy impacts from vehicle crashes raise suspicion. Imaging plays a key role: mediastinal widening on a chest X-ray can be an early clue, but the definitive assessment is with CT angiography in a stable patient or transesophageal echocardiography if the patient cannot undergo CT. Management aims for rapid control of bleeding, often through endovascular stenting or surgical repair, depending on stability and resources.

Pneumothorax and hemothorax, pulmonary contusion, and flail chest are important chest injuries to recognize and treat, but they involve the pleural space, lung tissue, or chest wall rather than a major vessel disruption.
