Emergency Medical Technician (EMT) Intermediate Practice Exam

Which of the following statements regarding blunt chest trauma is correct?

1. Fractured ribs can tear the lung parenchyma or other vital intrathoracic organs

2. Blunt trauma does not affect internal organs

3. Fractures in the vertebrae are more serious than fractured ribs

4. All chest injuries present with visible deformity

The correct answer is: Fractured ribs can tear the lung parenchyma or other vital intrathoracic organs

The correct statement regarding blunt chest trauma is that fractured ribs can indeed tear the lung parenchyma or other vital intrathoracic organs. This is a critical concept in understanding the potential complications of chest injuries. When ribs are fractured due to blunt trauma, the sharp edges of the broken bones can puncture the lung tissue, leading to conditions such as pneumothorax (air in the pleural space), hemothorax (blood in the pleural space), or lung contusions. These injuries can compromise respiratory function and lead to significant morbidity if not promptly recognized and managed. Other statements in the question do not accurately reflect the realities of blunt chest trauma. For instance, blunt trauma can significantly affect internal organs, contradicting the notion that it does not. Additionally, while fractures in the vertebrae can be serious due to potential spinal cord involvement, they are not inherently more serious than fractured ribs, as the impact of any injury can vary based on multiple factors such as the mechanism of injury and the specific organs involved. Lastly, not all chest injuries present with visible deformity; many internal injuries may occur without any external signs, making it essential for medical professionals to consider symptoms and mechanisms of injury during assessment.
