What is the maximum score of Glasgow Coma (GCS) scale?

Appeared in: NORCET 3 - 2022 (Shift-2)

Explanation

The Glasgow Coma Scale (GCS) is the sum of scores from three categories: Eye Opening (E), Verbal Response (V), and Motor Response (M).
The maximum score for each category is E=4, V=5, and M=6.
The total maximum score is the sum of the individual maximums: 4 + 5 + 6 = 15.
A score of 15 indicates a fully awake, alert, and oriented patient.

Option B: A score of 12 falls into the 'moderate brain injury' category (GCS 9-12). It is not the maximum possible score.
Option C: A score of 3 is the minimum possible score on the GCS, indicating a deep coma or unresponsive state. It is the opposite of the maximum score.
Option D: A score of 10 is within the 'moderate brain injury' range (GCS 9-12). It is not the maximum score.

Clinical Relevance

Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain Glasgow Coma Scale (GCS) Scoring as background academic context rather than a clinical decision trigger.
The GCS is a universal tool for nurses to objectively assess and communicate a patient's neurological status, especially after head trauma.
A drop of 2 or more points on the GCS is a critical finding that requires immediate notification of the physician, as it can indicate neurological deterioration.
The phrase 'GCS less than 8, intubate' is a common clinical guideline, highlighting that a patient with a GCS score of 8 or less is unable to protect their own airway and may require mechanical ventilation.

How to Approach the Question

Identify the core concept of the question, which is the scoring system of the Glasgow Coma Scale (GCS).
Recall the three components of the GCS: Eye Opening, Verbal Response, and Motor Response.
Remember the maximum score for each individual component: Eye (4), Verbal (5), and Motor (6).
Sum the maximum scores of the three components to find the total maximum GCS score (4 + 5 + 6).
Select the option that matches your calculated total.
