Which data indicate a favorable resolution of a fat embolism following multiple fractures?

• A. Clear chest x-ray
• B. Elevated WBC count
• C. Persistent fever
• D. Chest pain with cough

Answer: (A)

Understanding fat embolism after multiple fractures hinges on how the lungs recover as the fat droplets are cleared and the inflammatory response settles. When the pulmonary involvement improves, the chest radiograph shows clearing of the diffuse infiltrates and edema that were present during the embolic event. A clear chest x-ray thus reflects reduced embolic burden and healing of the lung tissue, signaling favorable resolution. Elevated white blood cell count is a nonspecific stress or inflammatory response and doesn’t confirm that the embolic process has subsided. A persistent fever points to ongoing inflammation or infection, not improvement. Chest pain with cough can be part of the initial presentation but doesn’t indicate that the fat embolism is resolving. Therefore, the most reassuring sign of recovery in this context is a clear chest x-ray.
