Final answer:
The Glasgow Coma Scale (GCS) is used to assess the level of consciousness in a patient. Based on the patient's symptoms, their GCS score would be 13.
Step-by-step explanation:
The Glasgow Coma Scale (GCS) is used to assess the level of consciousness in a patient. It measures three key areas: eye-opening, motor response, and verbal response. The scores for each area range from 1 to 4, with a higher score indicating a higher level of consciousness. In this case, the patient has his eyes open, follows commands to squeeze his hands, but is confused about what happened and his whereabouts. Based on these findings, the GCS score would be 13, which corresponds to an eye-opening score of 4, a motor response score of 6 (following commands), and a verbal response score of 3 (confused).
