A 28-year-old patient with a history of head injury is brought to the emergency department. The nurse performs a rapid neurological assessment using the Glasgow Coma Scale (GCS). The findings are recorded in the table below:

Behaviour	Response	Score
Eye opening response	Opens eyes to pain	2
Verbal response	Speaks inappropriate words	3
Motor response	Abnormal flexion observed	3
Total GCS score		8

The nurse in the ER makes a quick neurological assessment of the patient using Glasgow Coma Scale. Her assessment findings are shown in the given table. What will you interpret based on the given table?

1. A

   Moderate brain injury

2. B

   No neurological deficit

3. C

   Severe brain injury

4. D

   Mild brain injury

Appeared in: AIIMS Jodhpur SNO-2023

Explanation

• The Glasgow Coma Scale (GCS) is a standardized tool used to assess the level of consciousness and classify the severity of a brain injury.
• The patient's total score is calculated by summing the points for each response: Eye Opening (2) + Verbal Response (3) + Motor Response (3) = 8.
• According to standard clinical guidelines, a GCS score between 3 and 8 indicates a severe brain injury, which is often classified as a comatose state.
• This score signifies a critical condition requiring urgent medical intervention, particularly for airway protection, as reflexes are often compromised.

Why Other Options Were Wrong

• Option A: A moderate brain injury is incorrect. This classification corresponds to a GCS score of 9 to 12.
• Option B: A GCS score of 8 indicates a severe neurological deficit. A patient with no neurological deficit would have a GCS score of 15.
• Option D: A mild brain injury is incorrect. This classification is reserved for GCS scores of 13 to 15.

Clinical Relevance

• Nursing practice connection: Prioritize focused assessment, early escalation, and real-time monitoring when managing Interpretation of Glasgow Coma Scale (GCS) for classifying traumatic brain injury severity in acute care settings.
• The GCS is a fundamental skill for nurses in emergency, critical care, and neurology settings for rapid assessment and communication of a patient's neurological status.
• A declining GCS score is a critical warning sign of worsening brain injury (e.g., due to swelling or bleeding) and requires immediate escalation to the medical team.
• The mnemonic 'Less than 8, intubate' is a crucial patient safety principle, emphasizing that patients with a GCS ≤ 8 are unable to protect their airway and are at high risk for aspiration and respiratory failure.

How to Approach the Question

• First, identify the core task of the question, which is to interpret a set of findings from a Glasgow Coma Scale assessment.
• Review the table provided and sum the individual scores for each category: Eye Opening (2) + Verbal Response (3) + Motor Response (3).
• Calculate the total GCS score, which is 8 in this case.
• Recall the standard classification system for traumatic brain injury based on GCS scores: Mild (13-15), Moderate (9-12), and Severe (3-8).
• Compare the patient's calculated score (8) with the classification ranges.
• Select the option that correctly matches the patient's score to the severity level. A score of 8 falls squarely in the 'Severe brain injury' category.
