Question 3 of 34

The Glasgow Coma Scale (GCS) includes:

Oculomotor response, best verbal response, best motor response, light touch.

Eye opening, best motor response.

Best verbal response, best motor response, eye opening.

Best verbal response, best motor response, oculomotor response.

Pupillary response, best verbal response, best motor response.

Total GCS = Best Motor Response (1–6) + Best Verbal Response (1–5) + Eye Opening (1–4) = 3–15. The score ranges from 3 (no response) to 15 (best response). There are helpful mnemonics; the letter “E” (for eye) has four straight lines, and Eye Opening has a maximum score of 4. “Verbal” begins with the letter “V,” which is also the Roman numeral for “5,” and Best Verbal Response has a maximum score of 5. The value of this system is the ability to rapidly quantify a patient's level of consciousness (LOC) with an easily repoduced system. The LOC is the most important factor in the assessment of the head injured patient. This examination is reproducible by all levels of health care providers. The motor response is the most important and reproducible component of the examination. Severe injury is defined as a score of 8 or less persisting for at least 6 hours. Moderate injury is defined as a score of 9–12. A patient with a score of 8 or below (in the setting of head trauma) should be intubated for airway protection.
