Which statement about chest trauma in children is correct?

• A. Children are more prone to intrathoracic trauma due to compression forces.
• B. The rib cage in children is more rigid, reducing injury risk.
• C. Chest trauma in children rarely causes pneumothorax.
• D. The lungs are less susceptible to contusion in children.

Answer: (A)

In blunt chest trauma, the energy of impact in children is transmitted into the chest cavity because their chest wall is highly compliant and ribs are still cartilage-rich. That means external compression tends to deform the chest rather than absorb the energy with rigid bones, so intrathoracic structures are at higher risk even when there aren’t obvious rib fractures. This makes children more prone to intrathoracic injury from compression forces, which is why this statement is the best choice. The other points don’t fit pediatric anatomy and injury patterns. The rib cage in kids is not rigid; it’s more flexible, so injuries can occur without a fracture. Chest trauma can and often does cause pneumothorax, not rarely. And the lungs aren’t shielded from contusion in children; contusions can occur with blunt trauma as energy disrupts lung tissue.
