**Core Concept**
Management of head injury focuses on stabilizing the patient, controlling intracranial pressure (ICP), and preventing secondary brain injury. Key interventions include sedation, neuromuscular paralysis to reduce ICP, and vasopressors for hypotension. Glucocorticoids are not routinely used in head injury due to lack of proven benefit and potential adverse effects.

**Why the Correct Answer is Right**
Glucocorticoids (e.g., dexamethasone) are not recommended in head injury patients because they do not reduce intracranial pressure and may increase risk of infection and metabolic complications. In contrast, neuromuscular blockade (A) reduces cerebral metabolic demand and ICP, sedation (C) helps control agitation and ICP, and nor-epinephrine (B) is used in hypotensive patients to maintain perfusion pressure. Evidence shows no significant benefit from glucocorticoids in traumatic brain injury.

**Why Each Wrong Option is Incorrect**
Option A: Neuromuscular paralysis is used in severe head injury to reduce cerebral metabolic demand and ICP via decreased muscle activity.
Option B: Nor-epinephrine is used in hypotension to maintain cerebral perfusion pressure, especially in shock states post-injury.
Option C: Sedation is a cornerstone in head injury management to reduce ICP and agitation, commonly given in ICU settings.

**Clinical Pearl / High-Yield Fact**
Glucocorticoids have no role in traumatic brain injury — their use is contraindicated due to lack of benefit and potential harm. Avoid them in all head injury patients.
