What is the appropriate action for a patient with a GCS of 15?

When a patient presents with a Glasgow Coma Scale (GCS) score of 15, it indicates that they are fully alert and functioning normally, as this score reflects the highest level of cognitive response. In this context, routine observation is the most appropriate course of action.

A GCS of 15 typically signifies that the patient does not have any apparent neurological deficits and is not in immediate danger of respiratory failure or significant brain injury. Consequently, closely monitoring the patient's condition without unnecessary interventions is appropriate.

While the other options, such as immediate surgery, emergency intubation, and diagnostic imaging, may be warranted in cases where a patient's GCS is lower than 15 or if other concerning symptoms are present (such as significant trauma, altered mental status, or respiratory distress), none of these are indicated for a patient who is fully alert and engaged. Routine observation allows healthcare providers to track any changes in the patient's condition over time without exposing them to unnecessary risk or procedures.
