A
Pneumothorax
B
Flail chest
C
ARDS
D
Tension pneumothorax
Explanation: 

Detailed explanation-1: -Paradoxical movement is an obvious sign that the portion of the chest wall is not assisting with the breathing function. Other symptoms of flail chest can include: Bruises, grazes, and/or discoloration in the chest area. Telltale markings from a seat belt.

Detailed explanation-2: -The priority for any chest trauma client is airway, breathing, circulation. The nurse first ensures the client has a patent airway.

Detailed explanation-3: -The characteristic paradoxical motion of the flail segment occurs due to pressure changes associated with respiration that the rib cage normally resists: During normal inspiration, the diaphragm contracts and intercostal muscles pull the rib cage out.

Detailed explanation-4: -Pneumothorax with Tension The following are features unique to tension pneumothorax: Mediastinum gets pushed to opposite side. Diaphragm gets pushed downward resulting in decreased diaphragmatic excursion. In extreme cases it becomes concave upwards resulting in paradoxical movement with respiration.
