Which finding is the most concerning in a patient with suspected head injury?

• A. Glasgow Coma Score decreases from 13 to 10
• B. Pulse oximetry decreases to 93
• C. Pulse oximetry decreases from 95 to 92
• D. Glasgow Coma Score decreases from 13 to 12

Answer: (A)

In suspected head injury, changes in the patient’s level of consciousness are the most alarming signs, because they reflect how the brain is tolerating the injury and whether intracranial processes are worsening. A drop in Glasgow Coma Score from 13 to 10 shows a meaningful decline in brain function, suggesting evolving pathology such as bleeding, edema, or rising intracranial pressure. This kind of neurological deterioration requires immediate action—secure the airway, ensure adequate oxygenation, monitor closely, prepare for rapid transport, and notify the receiving facility—because it indicates the brain is not coping well with the injury. Lower oxygen saturation is important and should be corrected, but a decrease from 95 to 92 or to 93% is a systemic concern rather than a direct, rapid sign of neurological decline. The key reason this scenario is most concerning is that the neurological drop directly signals worsening brain injury rather than just a breath- or circulation-related issue.
