Naloxone administration routes in EMS standing orders may include which of the following?

• A. Intramuscular
• B. Intravenous
• C. Intranasal
• D. Oral

Answer: (C)

Naloxone in EMS standing orders is chosen for routes that allow rapid reversal of opioid overdose with minimal setup and safety concerns. The intranasal route fits best because it is needleless and easy to administer, so providers can deliver a dose quickly without obtaining IV access. This quick, accessible delivery is crucial in the field where seconds count and IV lines may not be readily available. The nasal mucosa absorbs the medication promptly, producing a fast onset of action, which is essential for reversing respiratory depression.

Oral naloxone, by contrast, is not suitable in this setting because it has poor bioavailability and takes too long to work, which could leave the patient at risk during an overdose. Intramuscular or intravenous administration can occur, but they require injections or IV access, more equipment, and stepwise procedures that slow treatment in the prehospital environment. Intranasal naloxone thus represents the most practical and effective route for EMS standing orders.
