Which of the following components is not assessed under Glasgow Coma Scale (GCS)?

Appeared in: Uttarakhand CHO - 2021

Explanation

The Glasgow Coma Scale (GCS) is a standardized tool for assessing a person's level of consciousness after a brain injury.
It exclusively evaluates three categories of behavior: Eye Opening (E), Verbal Response (V), and Motor Response (M).
Reflexes, such as pupillary, corneal, or deep tendon reflexes, are an essential part of a comprehensive neurological examination but are not included in the GCS scoring system.

Option A: This is incorrect because Verbal Response is a core component of the GCS, assessing a patient's ability to communicate and their orientation.
Option B: This is incorrect because Eye Opening is one of the three fundamental components evaluated in the GCS to determine a patient's level of arousal.
Option D: This is incorrect because Motor Response is the most heavily weighted component of the GCS, reflecting the brain's ability to process commands and respond to stimuli.

Clinical Relevance

Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain Components of the Glasgow Coma Scale (GCS) as background academic context rather than a clinical decision trigger.
Nurses use the GCS to objectively track changes in a patient's neurological status over time. A drop in the GCS score can be the first sign of worsening brain injury, prompting urgent intervention.
The GCS score helps guide clinical decisions, such as the need for intubation and airway protection (typically for a GCS score of 8 or less).
What if the patient is intubated? The verbal response cannot be assessed. The score is then documented with a 'T' (e.g., GCS 7T), and a total score is not calculated. The focus remains on the eye and motor responses to monitor for changes.

How to Approach the Question

First, identify the keywords in the question: 'not assessed' and 'Glasgow Coma Scale (GCS)'.
This is a negative question, so you are looking for the option that does NOT belong.
Recall the three components of the GCS. A common mnemonic is EVM: Eye, Verbal, Motor.
Systematically check each option against the EVM mnemonic.
Verbal Response is 'V', Eye opening is 'E', and Motor Response is 'M'. All are part of the GCS.
'Reflexes' is not part of the EVM mnemonic, making it the correct answer.

Concept Tested & Keywords

Concept Tested: Components of the Glasgow Coma Scale (GCS)
Stem keywords: Glasgow Coma Scale, GCS, assessed, components
Lead-in keywords: not
Negative lead-in flag: This question uses negative framing ('not'), asking you to identify the component that is excluded from the Glasgow Coma Scale (GCS).
