**Core Concept**
The patient's myelopathy is likely due to acute spinal cord injury (SCI), which causes an inflammatory response and subsequent damage to the spinal cord. The goal of treatment is to minimize further injury and promote recovery by reducing inflammation and edema.

**Why the Correct Answer is Right**
Methylprednisolone is a corticosteroid that has anti-inflammatory properties. In the context of acute SCI, it is believed to work by reducing the production of pro-inflammatory cytokines and inhibiting the influx of neutrophils into the injured spinal cord. The recommended dose of methylprednisolone for acute SCI is 30 mg/kg administered intravenously over 15 minutes, followed by a continuous infusion of 5.4 mg/kg/hour for 23 hours. This dose has been shown to improve neurological outcomes and reduce the risk of complications.

**Why Each Wrong Option is Incorrect**
**Option A:** This dose is too low and would not be effective in reducing inflammation and edema in the spinal cord.
**Option B:** This dose is too high and may increase the risk of adverse effects, such as hyperglycemia and gastrointestinal bleeding.
**Option C:** This dose is not the recommended dose for acute SCI and would not provide the optimal anti-inflammatory effects.

**Clinical Pearl / High-Yield Fact**
In patients with acute SCI, early administration of methylprednisolone within 3-8 hours of injury is critical to maximize its effectiveness.

**Correct Answer:** C. 30 mg/kg + 5.4 mg/kg/hour
