**Question:** Total score in Glasgow Coma Scale of a conscious person is

A. 15
B. 14
C. 13
D. 12

**Core Concept:**
The Glasgow Coma Scale (GCS) is a widely used assessment tool to evaluate the level of consciousness in patients. It is composed of three components: eye opening (E), verbal response (V), and motor response (M). Each component is scored on a scale from 1 to 4, with higher scores indicating better consciousness level. A conscious person typically scores 4 in each component.

**Why the Correct Answer is Right:**
A conscious person would score 4 in each component of the Glasgow Coma Scale, resulting in a total score of 12 (4 x 3). Option A (15) is incorrect because it represents the worst possible score for a conscious person. Option B (14) is also incorrect as it is a score achieved by a patient with impaired consciousness. Option C (13) is not correct because it represents a score for a patient with mild impairment in consciousness.

**Why Each Wrong Option is Incorrect:**
Option D (12) is incorrect because it represents a score for a patient with a moderate impairment in consciousness, which is higher than the score for a conscious person (12 vs. 15).

**Clinical Pearl:**
The Glasgow Coma Scale is a valuable tool to monitor changes in a patient's level of consciousness during clinical care. It helps in assessing the severity of a patient's neurological impairment and guides the appropriate management and interventions. A score of 15 for a conscious patient indicates no neurological deficit and suggests minimal risk of complications. On the other hand, a score of 3 or less indicates a critical neurological condition necessitating immediate clinical action.

**Correct Answer:** .

A conscious person typically scores 4 in each component of the Glasgow Coma Scale, resulting in a total score of 12 (4 x 3).
