On arrival at an emergency scene where substance abuse is suspected, what is the priority action?

• A. Begin chest compressions
• B. Summoning more advanced medical personnel
• C. Check for a pulse
• D. Administering naloxone

Answer: (B)

The priority is to summon more advanced medical personnel. When you arrive at a scene with suspected substance abuse, bringing in ALS or other advanced responders ensures there’s immediate access to airway control, ventilation support, monitoring, IV access, naloxone administration, and rapid transport. This allows you to provide essential support while awaiting or coordinating definitive care.

As part of your rapid assessment, you would still check responsiveness, breathing, and pulse, but delaying to call for backup can hinder the patient’s chances, since overdoses often require interventions that go beyond basic first aid. Administering naloxone is important, but it should follow proper protocol and under appropriate supervision once advanced help is en route or present. Beginning chest compressions is appropriate only if there is no pulse.
