Final answer:
Hyperactivity is not a sign of narcotic/opioid overdose; rather, signs include pinpoint pupils, slow or shallow breathing, and unresponsiveness. Naloxone is a life-saving drug that can reverse the effects of opioid overdose.
Step-by-step explanation:
The physical sign of narcotic/opioid overdose that is not typically associated with such an event is Option 3: Hyperactivity. The common physical signs of an opioid overdose include pinpoint pupils, slow or shallow breathing, and unresponsiveness. Opioids typically lead to depressive effects on the central nervous system, which manifest as reduced breathing, drowsiness, and unresponsiveness. Hyperactivity is not a symptom of opioid overdose; it is more likely associated with stimulant overdose or other conditions.
In the context of opioid overdose, it is crucial to note that substances like Naloxone (Narcan) are essential life-saving drugs that can reverse the effects of an overdose by antagonizing the actions of opioids. With overdoses, timely administration of Naloxone can prevent death by restoring normal breathing in the affected individual.
