Which physical sign would confirm opioid intoxication?

• A. Bradycardia
• B. Mydriasis
• C. Diaphoresis
• D. Rhinorrhea

Answer: (A)

Opioid intoxication slows the body's systems through increased vagal tone and CNS depression, so heart rate can drop as part of its autonomic effects. Among the given signs, a slower heart rate fits best with opioid overdose because it reflects this overall depressant effect on physiology. Pupillary constriction is the classic hallmark of opioid effect, but since dilated pupils would point away from opioids, that option is not supportive here. Excessive sweating can occur but is not specific to opioid intoxication and can be seen with many conditions. Rhinorrhea is more characteristic of withdrawal rather than intoxication. So, a slower heart rate is the most consistent clue for opioid intoxication among these choices.
