Final answer:
In a life-threatening emergency associated with opioids, where a person is unresponsive and not breathing normally but has a pulse, the administration of naloxone (Narcan) can help wake up the person and maintain their breathing until emergency medical treatment is provided.
Step-by-step explanation:
In the case of a person who is unresponsive and not breathing normally but has a pulse, it could be a life-threatening emergency associated with opioids. Opioids can slow or stop a person's breathing, causing overdose deaths. In this situation, the immediate administration of naloxone (Narcan) can help wake up the person and keep them breathing until they can receive emergency medical treatment.
