A rescuer arrives at the side of an adult victim and suspects an opioid-associated life-threatening emergency. The victim is unresponsive and not breathing normally but has a pulse. Which action should the rescuer do next?

A. Administer Naloxone.
B. Begin CPR with chest compressions.
C. Monitor the victim and wait for EMS.
D. Give rescue breaths.

If a victim is suspected of opioid overdose, is unresponsive, not breathing normally but has a pulse, the rescuer should administer Naloxone and provide rescue breaths while waiting for EMS. Therefore, the correct options are A and C.

Explanation:

In a situation where an adult victim is suspected to have an opioid-associated life-threatening emergency, is unresponsive, not breathing normally but has a pulse, the rescuer should administer Naloxone (a) if it's available and they are trained to do so. Naloxone (Narcan) is an opioid antagonist that can temporarily reverse the effects of opioid overdose and can restore normal breathing in the victim until emergency medical services (EMS) take over.

While waiting for EMS to arrive, the rescuer should also provide rescue breaths (c) to support the victim's breathing, assuming there are no signs of injuries that contraindicate giving rescue breaths.
