Rosie's T-FAST result indicated which finding?

• A. Pleural effusion with echogenic fluid
• B. No pleural effusion
• C. Pneumothorax
• D. Consolidation of lung tissue

Answer: (A)

T-FAST is used to quickly detect free fluid in the chest and abdomen after trauma. In the chest, fluid in the pleural space shows up as a dependent fluid collection; when that fluid is echogenic, it suggests blood products rather than clear fluid. So, seeing pleural fluid that is echogenic points to a pleural effusion due to bleeding—a hemothorax. That’s why this finding fits Rosie’s result. If there were no pleural effusion, you wouldn’t see fluid in the chest; a pneumothorax would present with air in the pleural space and loss of lung sliding, not fluid; consolidation refers to abnormal lung tissue rather than a free fluid collection in the pleural space.
