Final answer:
Paradoxical movement is associated with c) Flail chest. It refers to an abnormal inward movement of a segment of the chest wall during inspiration, caused by the traumatic injury of multiple ribs.
Step-by-step explanation:
Paradoxical movement is associated with c) Flail chest.
Paradoxical movement refers to an abnormal inward movement of a segment of the chest wall during inspiration, caused by a traumatic injury to multiple ribs, leading to instability of the chest wall. This results in a paradoxical pattern of movement, where instead of expanding during inspiration, the affected segment of the chest wall moves inward, compromising the normal respiratory function. Flail chest is a condition caused by the fracture of multiple adjacent ribs, leading to paradoxical movement and impaired breathing.
For example, if a person has a flail chest due to rib fractures on one side of the chest, when they try to take a breath, the affected side of the chest may move inward instead of expanding outward.
