The initial radiograph taken demonstrates an endotracheal tube in place with its tip at the level of T3-T4, a chest tube within the left hemithorax, and a sharp metallic object overlying the left hemithorax, suggestive of a foreign body. There is no evidence of pneumothorax, the lungs appear clear, and there is no pleural effusion. The cardiomediastinal silhouette is within normal limits, and there are no bony abnormalities.
