Which of the following is a sign of excited delirium?

• A. Elevated pulse
• B. Knowledge of suspect history
• C. Calm demeanor
• D. No sweating

Answer: (A)

Excited delirium is a state of extreme agitation with strong sympathetic nervous system activation, so the heart rate tends to climb as the body hypes up for action. An elevated pulse is a direct, observable sign of that heightened arousal, which is why it’s the most relevant option among the choices. The other options don’t reflect the current physiological state: knowledge of suspect history isn’t about how the body is behaving right now, a calm demeanor contradicts the intense agitation, and not sweating runs counter to the diaphoresis often seen with this condition (though sweating can vary). Recognizing a rising heart rate helps you gauge the level of urgency and necessary medical monitoring and safety measures.
