**Core Concept**
Fat embolism syndrome (FES) is a clinical condition characterized by the presence of fat globules in the bloodstream, leading to respiratory, neurological, and cardiovascular complications. It typically occurs after a significant traumatic injury, especially long bone fractures. The management of FES involves supportive care, stabilization of the patient, and addressing the underlying cause.

**Why the Correct Answer is Right**
The management of FES includes stabilizing the patient, maintaining adequate oxygenation and ventilation, and administering corticosteroids to reduce inflammation. Corticosteroids, such as dexamethasone, have been shown to decrease the severity and duration of FES symptoms by reducing the inflammatory response. Additionally, patients with FES may require transfusions of packed red blood cells, platelets, and fresh frozen plasma to correct coagulopathy.

**Why Each Wrong Option is Incorrect**
**Option A:** This option is not a standard treatment for FES. While some studies suggest the use of heparin in FES, it is not a widely accepted or recommended treatment.
**Option B:** Corticosteroids, such as dexamethasone, are a standard treatment for FES and are used to reduce inflammation and decrease the severity and duration of symptoms.
**Option C:** Supportive care, including maintaining adequate oxygenation and ventilation, is a critical component of FES management.
**Option D:** This option is not a standard treatment for FES. While some studies suggest the use of beta-blockers in FES, it is not a widely accepted or recommended treatment.

**Clinical Pearl / High-Yield Fact**
A significant traumatic injury, especially a long bone fracture, increases the risk of developing FES. Early recognition and management of FES are crucial to improve patient outcomes.

**Correct Answer: A.**
