**Question:** Mild head injury is having Glasgow Coma Scale of

A. 13
B. 14
C. 15
D. 16

**Core Concept:** Glasgow Coma Scale (GCS) is a widely used clinical tool for assessing the severity of head injury and evaluating the level of consciousness in patients. The scale consists of three components: eye opening, verbal response, and motor response, each scored from 1 to 6. The total score ranges from 3 to 15, with lower scores indicating more severe injury and poorer prognosis.

**Why the Correct Answer is Right:** The Glasgow Coma Scale is used to evaluate the level of consciousness in head injury patients. Mild head injury is defined as a GCS score of 13-15, indicating a good prognosis and relatively normal neurological function. In this case, the correct answer is 14 because it falls within the range for mild head injury.

**Why Each Wrong Option is Incorrect:**

A. Lower GCS score (13) indicates a more severe head injury, not mild.
B. Higher GCS score (16) indicates an even milder injury, not a mild injury.
C. 15 is the maximum possible GCS score, indicating no neurological deficit, which is not consistent with mild head injury.

**Clinical Pearl:** The Glasgow Coma Scale plays an essential role in assessing the severity of head injury and guiding treatment decisions. It is crucial for healthcare professionals to accurately interpret GCS scores to ensure appropriate patient management and predict prognosis accurately.

**Correct Answer:** D. 14
