EMT Operations Study Guide

This study guide covers Operations for EMTs. It aligns with the NREMT EMT certification exam (updated format effective April 2025), National EMS Education Standards, National EMS Scope of Practice Model 2019 (with Change Notices through 2021), and current prehospital operations guidelines. Operations account for approximately 10–14% of the NREMT EMT exam and are tested across Scene Size-Up, Patient Treatment and Transport, and EMS Operations domains. EMT Role in Operations: Ensure scene safety first, manage single- and multi-patient incidents, perform basic triage, communicate effectively, document accurately, lift and move patients safely, interact appropriately with special populations, and follow EMS system rules (destination selection, patient refusal, mandatory reporting, etc.). Operations emphasize safety, teamwork, legal/ethical responsibilities, and efficient patient flow. Key Principle: Scene safety is non-negotiable—every single call. Use Incident Command System (ICS) principles even on routine calls. Always prioritize life threats, minimize on-scene time for unstable patients, and document everything as if it will be reviewed in court.

Section 1: Scene Size-Up & Personal/Scene Safety

Scene Size-Up Steps (NREMT Emphasis):

• BSI / Standard Precautions – Gloves, mask, eye protection before patient contact.
• Scene Safety – Traffic, fire, violence, downed wires, hazardous materials, unstable structures, animals.
• Mechanism of Injury / Nature of Illness – High-energy trauma? Medical vs. trauma?
• Number of Patients – Request additional resources early if multiple casualties.
• Need for Additional Resources – ALS intercept, law enforcement, fire, air medical, hazmat.
• C-spine Precautions – Apply if MOI suggests spinal injury.

Safety Red Flags:

• Domestic violence / behavioral emergency → Stage until law enforcement clears.
• Roadway incidents → Use traffic cones, flares, reflective vests; park appropriately (upstream blocking).
• Suspected hazmat → Stay upwind/uphill, request specialized team.
• Infectious disease outbreak → Droplet/airborne precautions, limit exposure.

Section 2: Lifting, Moving & Patient Packaging

Body Mechanics Rules:

• Keep load close to body.
• Bend at hips and knees, not waist.
• Use leg muscles, keep back straight.
• Communicate (“ready, lift”) with partner(s).

Emergency Moves (Immediate Danger):

• Clothes drag
• Extremity drag
• Firefighter’s carry
• Blanket drag

Non-Emergency Moves (Stable Patient):

• Direct ground lift
• Extremity lift
• Draw-sheet method
• Stair chair (preferred for stairs)

Devices & Packaging:

• Wheeled ambulance cot
• Stair chair
• Long backboard (spinal motion restriction)
• Scoop stretcher
• Flexible stretcher
• Bariatric equipment when needed

Special Populations:

• Pediatrics: Keep parent/guardian involved; pediatric immobilization devices.
• Geriatrics: Fragile skin/bones; gentle handling.
• Bariatric: Additional personnel, specialized cot/stretcher.
• NREMT Skill: Patient Handling – Verbalize BSI; choose correct method; maintain spinal alignment if indicated; secure patient safely.

Section 3: Multiple Casualty Incidents (MCI) & START Triage

START Triage (Simple Triage and Rapid Treatment):

• Walk – Ask patients to walk to a designated area → Minor (Green).
• Assess remaining patients: Respirations? No → Open airway → Still no → Deceased/Expectant (Black). Yes → RR >30 or <10 → Immediate (Red). RR normal → Check perfusion (radial pulse or cap refill >2 sec) → Absent/delayed → Immediate (Red). Perfusion normal → Check mental status → Cannot follow commands → Immediate (Red). Follows commands → Delayed (Yellow).

Color Categories:

• Red (Immediate) – Life threats that can be stabilized quickly (airway, severe bleeding, shock).
• Yellow (Delayed) – Serious but stable (fractures, burns without shock).
• Green (Minor) – Walking wounded.
• Black (Deceased/Expectant) – No respirations after airway opened.

EMT MCI Role:

• Initiate triage until relieved. Report findings to Incident Commander. Assist with treatment/transport as directed. Use triage tags if available.

Section 4: Transport Decisions & Destination Selection

Factors to Consider:

• Patient stability
• Closest appropriate facility (trauma center, stroke center, STEMI/PCI center, pediatric center)
• Specialty care availability (burn, spinal cord, hyperbaric)
• Traffic, weather, distance
• Patient/family preference (if stable and appropriate)

Lights & Sirens Justification:

• Use only when time to hospital will make a clinical difference. Document rationale (unstable vitals, time-sensitive condition).

Patient Refusal / AMA:

• Assess decision-making capacity (alert, oriented, understands risks/benefits). Explain risks clearly and document refusal. Have patient sign refusal form; obtain witness signature. Involve supervisor/medical control for high-risk refusals.

Restraint Application:

• Only if patient is danger to self/others. Soft restraints preferred; document justification, time applied, frequent reassessments (every 15 min), circulation checks.

Section 5: Radio Communication & Documentation

Radio Report Structure (Typical):

• Unit identification and destination.
• Patient age/sex.
• Chief complaint / MOI or NOI.
• Mental status (AVPU or GCS).
• Vital signs (most recent set).
• Pertinent history (SAMPLE/OPQRST).
• Interventions and patient response.
• ETA and any special requests.

PCR Documentation Essentials:

• Accurate, objective, timely. Include: Times (arrival, interventions, departure), vitals trends, reassessments, refusals, signatures.
• Errors: Single line-through, initial, date/time; never leave blank spaces.
• Narrative: Chronological, avoid slang, use “patient reports” not “patient stated.”

Mandatory Reporting (Common Requirements):

• Suspected child/elder abuse or neglect
• Gunshot/stab wounds
• Certain infectious diseases
• Impaired drivers (per state law)

Section 6: NREMT Operations Skill Emphasis & High-Yield Scenarios

• Bleeding Control / Shock Management – Often integrated with operations.
• Patient Assessment – Medical / Trauma – Scene size-up is first step.
• Scenarios: MVC with 5 patients → Initiate START triage, request additional units, establish treatment area. Domestic violence scene → Stage until law enforcement clears, then enter with officers. Patient refuses transport after chest pain → Assess capacity, explain risks of MI, document refusal thoroughly.

Example Math (Scene Time / ETA Calculation):

Question: Scene is 9 miles from hospital. Ambulance averages 36 mph in traffic. Estimated on-scene to hospital time (excluding loading)? Solution: Time = distance ÷ speed = 9 ÷ 36 = 0.25 hours = 15 minutes. Reasoning: Convert hours to minutes (0.25 × 60 = 15 min); add 3–5 min for loading/unloading in real scenarios. Review NREMT skill sheets (Patient Assessment – Medical/Trauma, Bleeding Control/Shock, Spinal Immobilization) and practice operations-focused scenarios: triage, lifting techniques, radio reports, refusal documentation, and scene safety decisions. Focus on safety, triage accuracy, and clear communication. Good luck on your EMT exam—scene safety first, every single time! 🚑
