Which client should be prioritized due to the risk of fat embolism?

The client who should be prioritized due to the risk of fat embolism is the 34-year-old with a femur fracture and low oxygen saturation. Fat embolism syndrome occurs when fat droplets enter the bloodstream, often following trauma, especially to long bones such as the femur. This can lead to serious complications, including respiratory distress and impaired oxygenation.

In this case, the femur fracture presents a significant risk for the development of fat embolism because the injury can release fat globules into the systemic circulation. The accompanying low oxygen saturation indicates that the client may already be experiencing respiratory issues, which could be exacerbated by a fat embolism. Therefore, this client requires immediate assessment and intervention to prevent further respiratory compromise and to address the potential for fat embolism-related complications.

Other clients, while they may have significant medical issues (such as cellulitis, hyponatremia, or a urinary tract infection), do not present the same acute risk for fat embolism as the patient with the femur fracture. The combination of the specific injury and the signs of hypoxia elevate the urgency for this client.
