In addition to CPR and AED application for a patient in cardiac arrest with drug paraphernalia, what should be administered?

In cases of cardiac arrest, particularly when drug paraphernalia is present, it is crucial to consider the possibility of opioid overdose as a contributing factor. Naloxone is an opioid antagonist that can effectively reverse the effects of opioids, restoring the patient's respiratory drive and perfusion if they're in cardiac arrest due to opioid use.

Administering Naloxone in this scenario aligns with the emergency response protocols, as it allows for potential restoration of consciousness and improved hemodynamics, thereby increasing the chances of successful resuscitation. The rapid administration of Naloxone in conjunction with CPR and AED can be life-saving in a situation where opioids are involved.

The other options do not address the specific needs of a patient potentially experiencing an opioid-related cardiac arrest. Oral instant glucose, for example, is used for hypoglycemia and would not be appropriate in an unresponsive patient without a secured airway. Nitroglycerin is indicated for chest pain associated with angina or myocardial infarction, but it is not suitable for a patient in cardiac arrest. A metered dose inhaler is typically used for respiratory conditions like asthma, which would not be relevant to a patient undergoing cardiac arrest. Thus, Naloxone is the most appropriate and potentially life-saving
