Medication Orders and Medical Direction

Category: Operations Sources: UCLA EMT Ultimate Study Guide (2026) Last updated: 2026-05-06

Overview

EMT-B providers operate under physician medical direction. Every medication administered and every intervention performed is authorized by a physician — either in advance (standing orders) or in real time (online medical control). Understanding the distinction between off-line and on-line medical direction, the process for medication verification, and the limits of EMT-B scope is essential both for patient safety and for NREMT testing.

Key Points

  • Medical Director is a physician who authorizes EMT-B scope of practice and oversees clinical quality; all EMS agencies must have one
  • Off-line medical direction = standing orders; pre-authorized protocols for conditions where delayed treatment is harmful
  • On-line medical direction = real-time physician contact (radio or phone) for orders not covered by standing orders
  • EMT-B may NOT administer medications without authorization — either from standing order or on-line physician order
  • Two-provider medication check: before administering any medication, verify the right patient, right drug, right dose, right route, right time, right documentation
  • Assist vs. administer: EMT-B typically assists patients with their own prescribed medications (epi auto-injector, nitroglycerin, albuterol inhaler) — some systems allow EMT-B to administer from agency stock

Medical Direction Framework

Type Also Called Description When Used
Off-line medical direction Standing orders; protocols; off-line control Pre-written physician-authorized protocols — no contact required at time of use Most field interventions: assessment, O2, splinting, hemorrhage control
On-line medical direction Medical control; on-line control Real-time physician contact via radio or phone Orders outside standing protocols; medication orders not pre-authorized; destination decisions; patient refusals
Prospective (a form of off-line) Protocol development Medical director designs protocols, training, equipment standards Before calls — sets the framework
Retrospective (a form of off-line) QA/QI Medical director reviews past PCRs and performance After calls — quality improvement

KEY DIFFERENTIATOR — Off-line vs. On-line: Off-line = standing orders written in advance by the medical director — no call needed at time of use. On-line = you are on the radio or phone with a physician RIGHT NOW getting a specific order. Most EMT-B interventions are off-line. Contact medical control when the situation is outside your standing orders, when the patient is refusing care, or when you need a destination decision.

Medications in EMT-B Scope

EMT-B scope includes assisting patients with their own prescribed medications and administering a small set of agency-stocked medications, depending on protocol:

Medication Route Authorization Needed Indication
Oxygen Inhalation Standing order Any hypoxia or suspected hypoxia
Oral glucose Oral (PO) Standing order Conscious hypoglycemic patient who can swallow
Epinephrine auto-injector (EpiPen) IM — lateral thigh Standing order or on-line Anaphylaxis — no contraindications in true anaphylaxis
Aspirin (ASA 324 mg) Oral (chew) Standing order or on-line Suspected MI (ACS) — contraindicated if allergy or active bleeding
Nitroglycerin (NTG) Sublingual On-line medical control required (in most systems) Chest pain — significant contraindications apply
Albuterol / MDI Inhalation On-line medical control required (in most systems) Bronchospasm — assist with patient's own prescribed inhaler
Activated charcoal Oral On-line medical control required Certain poisonings — many systems have removed from EMT scope
Naloxone (Narcan) IM, intranasal Standing order (most systems) Opioid overdose with respiratory depression

NREMT RULE — Assist vs. Administer: The NREMT distinguishes between assisting a patient with their own prescribed medication (patient has prescription, EMT helps with administration) and administering agency-stocked medication. In both cases, authorization (standing order or on-line) is required. For assisting: the medication must be prescribed to THIS patient, not a bystander's prescription.

Medication Administration — Safety Steps

The six rights of medication administration:

Right What to Check
Right Patient Is this medication for this patient? Is it their prescription (if assisting)?
Right Drug Does the medication match the order? Check label twice.
Right Dose Correct amount for patient weight/age? Adult vs. pediatric dose?
Right Route IM? Sublingual? Oral? Inhalation? Route determines speed of onset.
Right Time Not expired? Not contraindicated by recent doses?
Right Documentation Record: drug, dose, route, time, patient response, provider giving medication

Two-provider check: For any medication given from agency stock, a second EMT-B (or higher level provider) should independently verify the drug, dose, and route before administration. Both providers document.

Before any medication — contraindication check: - Patient allergies (ask every time) - Contraindications for the specific drug (e.g., NTG: no recent PDE-5 inhibitor use; no systolic BP <90 mmHg) - Patient's current medications (interactions) - Patient consent

Nitroglycerin — On-Line Order Requirements

NTG requires on-line medical control in most systems because of significant contraindications:

Absolute contraindications (do NOT give without physician order overriding): - Systolic BP < 90 mmHg (will cause dangerous hypotension) - HR < 50 or > 100 bpm (relative) - Patient took sildenafil (Viagra), tadalafil (Cialis), or similar PDE-5 inhibitor within 24 hours (48–72 hours for longer-acting agents) — combination causes severe refractory hypotension - Suspected right ventricular MI (inferior MI with RV involvement) — RV depends on preload; NTG drops preload and can precipitate cardiovascular collapse

If authorized: 0.4 mg sublingual (1 tablet or 1 spray); may repeat every 5 minutes × 3 doses if BP remains adequate. Reassess BP before each dose.

On-Line Medical Control — Communication Protocol

When contacting medical control, provide: 1. Unit identification and location 2. Patient age, sex, chief complaint 3. Pertinent history: SAMPLE, medications, allergies 4. Vital signs (current) 5. Assessment findings and treatments already given 6. Specific request: "Requesting authorization to administer [medication] [dose] [route]" 7. Repeat back any order received — state it back to confirm: "Copy, you want me to administer [medication] [dose] [route]" 8. Document the order, the physician's name, and exact time

NREMT RULE — Repeat Orders: Always repeat an on-line order back to the physician before implementing. This closes the loop and confirms you heard the order correctly. Document the order and the physician who gave it — this is your authorization trail.

Refusing/Stopping Treatment

Patient refusal: A competent adult may refuse any treatment or transport. Requirements: 1. Patient must have decision-making capacity (oriented, sober, not in shock) 2. Patient must be informed of the risks of refusal 3. EMT-B must encourage the patient to reconsider and offer alternatives 4. Contact on-line medical control — medical director guidance on refusal situations 5. Patient signs AMA (Against Medical Advice) form; have a witness 6. Document extensively: assessment findings, what was explained, patient's stated reason for refusal

Stopping resuscitation: EMT-B generally initiates and continues resuscitation unless a valid DNR/POLST is present, on-line medical control authorizes termination, or patient meets obvious death criteria.

NREMT Relevance

  • Off-line = standing orders (pre-authorized, no contact needed); on-line = real-time physician call
  • EMT-B requires authorization (off-line or on-line) before any medication
  • Six rights of medication: Right patient, drug, dose, route, time, documentation
  • NTG requires on-line medical control in most systems; never give if SBP <90 or recent PDE-5 inhibitor
  • Repeat back any on-line order before implementing; document physician name and time
  • Assist = patient's own prescription; administer = agency stock — both require authorization
  • AMA refusal: must have capacity, be informed of risks, sign form, contact medical control, document thoroughly
