Final answer:
The Glasgow Coma Scale score with just motor response information provided would be 6; however, a full assessment is necessary for a definitive GCS score. Medical intervention like aspirin therapy might be required if the cause is suspected to be an embolic event.
Step-by-step explanation:
The Glasgow Coma Scale (GCS) is a clinical tool used to assess a person's level of consciousness after a head injury. When a patient extends her arms and legs in response to a sternal rub, but shows no other response, we must score each of the three components of the GCS: eye response, verbal response, and motor response. As there is no mention of eye-opening or verbal response, we only have information on motor response.
Motor response to pain in a person who flexes (withdraws from pain) is a score of 4. Assuming no eye opening and no verbal response, those would each be scored as 1. Thus, without additional information on eye or verbal response, the GCS could be a minimum of 6 (M4+V1+E1).
It's essential to perform a complete assessment for an accurate GCS score. Onset of medical interventions such as aspirin therapy are critical if the suspected cause of the neurological deficit is an embolic event, which could be suggested from sensory deficits and the presence of pins and needles, known as paresthesia.
