As an expert in healthcare, if the family member stated that they had given the patient naloxone (Narcan), the EMT's should suspect that the patient has likely overdosed on opioids. Naloxone is a medication used to reverse the effects of opioid overdose and is often carried by individuals who are at risk of encountering people who have overdosed. Therefore, the administration of naloxone by a family member suggests that the patient may have ingested opioids before becoming unresponsive or "found down". The EMT's should initiate appropriate emergency care and transport the patient to the hospital as soon as possible.
