Among the listed signs of head trauma with blood, which is a sign?
Correct Answer:
Altered mental status
Explanation:
In head trauma, the important distinction is between signs (what you can observe) and symptoms (what the patient reports). Altered mental status is a sign because you can notice it—watch for confusion, disorientation, inability to follow commands, or unresponsiveness. These observable changes point to brain involvement and possible intracranial injury, demanding prompt assessment and urgent transport. Dizziness, headache, and nausea are symptoms: they’re subjective experiences the patient describes. They’re common with many illnesses or injuries and don’t by themselves indicate a direct, observable change in brain function the way altered mental status does.
