IV medications and treatments should be administered pursuant to a lawful order from a clinician with appropriate prescribing authority. How physician, APRN, and PA roles differ.
Clinical governance reviewed by Armando A. Falcon, MD (FL ME 84789) · Florida regulatory framework reviewed August 2026.
A registered nurse may administer medications and treatments prescribed or authorized by a duly licensed practitioner with authority to prescribe them — but an RN license does not itself create independent prescribing authority. The person who starts the IV and the person who authorizes the treatment may be different clinicians; build the workflow around that distinction.
Depending on license and practice structure: physicians may prescribe within scope; APRNs may have prescribing authority under Florida law (including autonomous practice for qualifying APRNs), subject to the applicable framework; and PAs provide delegated medical services with delegated prescribing authority consistent with Florida law. Verify the exact authority of the ordering clinician rather than labeling everyone a “provider.”
A clinically useful order or protocol framework addresses patient eligibility, solution, medication/nutrient components, concentration, volume, route, infusion rate, frequency, monitoring, contraindications, hold criteria, stop criteria, and escalation.
Separate the authorization decision (a prescriber, on a patient-specific basis or via a valid standing order) from the administration task (typically an RN within scope). Conflating them is where most IV-lounge scope problems start.
Identify an authorized ordering clinician and a patient-specific basis for treatment — don’t rely on the RN’s presence as if it were prescribing authority. Confirm with the practice acts and counsel.
