**Core Concept**
CSF rhinorrhea is a condition where cerebrospinal fluid (CSF) leaks through the nose due to a defect in the dura mater or cribriform plate. Immediate management aims to prevent complications like meningitis by stopping the CSF leak.

**Why the Correct Answer is Right**
The immediate goal is to reduce intracranial pressure (ICP) and prevent further CSF leakage. This is achieved by administering intravenous corticosteroids, such as dexamethasone, to reduce inflammation and swelling around the leak site. Additionally, patients are placed on bed rest with the head of the bed elevated to decrease ICP. **Option A** is correct because it involves the initial stabilization of the patient and reduction of ICP.

**Why Each Wrong Option is Incorrect**

**Option B:** This option is incorrect because it involves immediate surgical intervention, which is not typically required in the initial management of CSF rhinorrhea. Surgical repair is usually reserved for cases where conservative management fails.

**Option C:** This option is incorrect because it involves the use of nasal packing, which may worsen the CSF leak and increase the risk of complications.

**Clinical Pearl / High-Yield Fact**
It's essential to remember that the initial management of CSF rhinorrhea focuses on reducing ICP and preventing meningitis. Patients with CSF rhinorrhea should be treated as a neurosurgical emergency.

**Correct Answer: A. Immediate stabilization of the patient with intravenous corticosteroids and bed rest.**
