Final answer:
The patient's GCS score would be 8, indicating a severe altered mental state due to an unknown substance overdose, requiring immediate medical intervention.
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 or in the case of an overdose. The GCS assesses three aspects of a patient's responsiveness: eye, verbal, and motor responses. In the scenario described, where a 24-year-old female is overdose victim, staring off into space, writhing, and babbling, and cries out incomprehensibly to painful stimuli without pulling away, her GCS score would be calculated as follows:
- Eye response: 2 (Opens eyes to pain)
- Verbal response: 2 (Incomprehensible sounds)
- Motor response: 4 (Withdrawal from pain)
Adding these scores gives us a total GCS score of 8 (2+2+4). This indicates that the patient is in a severe altered mental state, which could potentially be life-threatening, and requires immediate medical attention.
