Final answer:
Opioid-associated life-threatening emergencies can occur due to the depressant effects of opioids on the central nervous system, leading to breathing difficulties. Immediate medical intervention, such as the use of naloxone, is necessary to prevent death.
Step-by-step explanation:
opioid-associated life-threatening emergency refers to a condition that can occur as a result of opioid use and abuse. Opioids, such as heroin and prescription painkillers, can depress the central nervous system and slow down or even stop a person's breathing, leading to a life-threatening emergency. This condition often requires immediate medical intervention to prevent death. Naloxone (Narcan) is an opioid overdose antidote that can revive a person and restore normal breathing temporarily, providing time for emergency medical treatment.
