Which of the following is the first step in administering Narcan?

The first step in administering Narcan is to call 911. This is crucial because an opioid overdose can be life-threatening, and while Narcan can temporarily reverse the effects, professional medical assistance is needed for continued care and support. Calling emergency services ensures that help is on the way, providing safety for the individual experiencing the overdose and allowing for further medical intervention when necessary.

The other choices involve actions that would follow after calling for emergency assistance. Administering Narcan would be the next immediate action, but without alerting medical personnel first, there is a risk of inadequate follow-up care. Stimulation techniques like sternum rubs may also be used to assess responsiveness or stimulate someone who is unresponsive, but they do not replace the need for emergency help. Monitoring response is vital after administering Narcan, but again, that can only happen after ensuring that emergency services are contacted so that ongoing medical support is guaranteed.
