**Core Concept**
In head trauma, computed tomography (CT) scans are crucial for diagnosing and managing patients with acute injuries. The decision to perform a CT scan involves assessing the severity of the trauma, potential for intracranial hemorrhage, and the need for surgical intervention.

**Why the Correct Answer is Right**
A Glasgow Coma Scale (GCS) score of 14 is considered mild head injury, which typically does not require immediate surgical intervention or CT scanning. Patients with a GCS of 14 may be observed in a monitored setting, and a CT scan is not necessary unless there is a change in their clinical condition or other concerning features. In contrast, patients with a GCS score ≤ 13 require immediate CT scanning to evaluate for potential intracranial hemorrhage or other injuries.

**Why Each Wrong Option is Incorrect**
**Option A:** Seizures are a common complication of head trauma and may indicate the presence of an underlying intracranial hemorrhage or other injury. A CT scan is essential in these cases to identify the cause of the seizure and guide management.

**Option B:** Loss of consciousness is a significant indicator of head trauma and requires a thorough evaluation, including a CT scan, to rule out intracranial hemorrhage or other injuries.

**Option D:** ENT bleed, or bleeding from the ears, nose, or throat, can be a sign of a more severe head injury, such as a basilar skull fracture. A CT scan is necessary to evaluate the extent of the injury and guide management.

**Clinical Pearl / High-Yield Fact**
In head trauma, a CT scan is essential in patients with a GCS score ≤ 13, seizures, or other concerning features, such as loss of consciousness or ENT bleed. A GCS score of 14 or higher may not require immediate CT scanning, but close observation and serial neurological examinations are necessary.

**✓ Correct Answer: C. GCS < 14**
