Final answer:
The man's Glasgow Coma Score would be 12, based on his eye opening and motor response. The Glasgow Coma Scale assesses a person's level of consciousness after a severe brain injury.
Step-by-step explanation:
The Glasgow Coma Scale (GCS) is used to assess a person's level of consciousness after a severe brain injury. It evaluates three parameters: eye opening, verbal response, and motor response. Each parameter is given a score from 1 to 5 or 1 to 6, and the scores are then added together to give an overall GCS score.
In this case, the man opened his eyes when you gave him a sternal rub, which suggests a GCS score of 3 for eye opening. He also pushed your hand away, indicating a purposeful motor response, which corresponds to a GCS score of 6 for motor response.
The verbal response is not mentioned in the question, so we cannot assign a specific score for that parameter. However, since the man told you to go away, we can assume he had some form of verbal response, which would give a minimum score of 3 for this parameter.
To calculate the Glasgow Coma Score, add the scores for eye opening, verbal response, and motor response. In this case, it would be 3 + 3 + 6 = 12. So the man's Glasgow Coma Score would be 12.
