Which physiologic sign is commonly associated with pain and can be present in acute distress?

• A. Tachycardia
• B. Hypotension
• C. Hypothermia
• D. Pallor

Answer: (A)

Acute pain and distress trigger a sympathetic nervous system response, often raising the heart rate as part of that fight-or-flight activation. This tachycardia reflects increased catecholamines and heightened bodily arousal in response to nociceptive input, making it a common and reliable sign in acutely distressed patients. While pallor, hypotension, or hypothermia can occur in various conditions, they are not as directly linked to the pain response as tachycardia, which is why it best fits the scenario.
