Content Domains & Weight Distribution

Content Domains & Weight Distribution (April 2025 Restructure)

Effective April 2025, NREMT restructured the EMT exam from the older topic-based model to a patient-centered, assessment-flow model drawn from the 2023 BLS Practice Analysis. The new domains mirror the sequence of a real-world patient encounter, from scene arrival through transport. The weights below are published in the official EMT Candidate Handbook.

Important: If your study materials still reference the previous topic domains (Medical/OB/GYN, Cardiology & Resuscitation, Airway/Respiration/Ventilation, Trauma, EMS Operations), those category labels no longer drive the blueprint. The clinical content is the same, but it is now organized by the phase of patient care rather than by clinical topic.

Domain Weight Distribution (April 2025)

Patient Population Distribution

Pediatric questions are integrated throughout all five domains, not isolated to a single section.

Domain 1: Primary Assessment (39-43%) — LARGEST DOMAIN

This is the biggest section of the exam, reflecting how central accurate assessment is to EMS. Topics include:

• General impression & level of consciousness: AVPU, initial appearance, chief complaint
• Airway assessment: opening the airway, assessing patency, recognizing obstruction
• Breathing assessment: rate, quality, breath sounds, signs of distress or failure
• Circulation assessment: pulse, skin color/temperature/condition (CTC), capillary refill, major bleeding
• Priority/transport decision: identifying life threats, determining urgency
• Vital signs: baseline and serial measurement and interpretation
• Clinical decision-making: forming a field impression and identifying immediate interventions

Domain 2: Patient Treatment & Transport (20-24%)

• Airway management interventions: suctioning, OPA/NPA, head-tilt/chin-lift, jaw thrust
• Oxygen delivery & ventilation: nasal cannula, non-rebreather, BVM, assisted ventilations
• CPR & AED: high-quality CPR, AED use, cardiac arrest management
• Bleeding control & shock management: direct pressure, tourniquets, shock treatment
• Splinting & immobilization: musculoskeletal injury care, spinal motion restriction
• Medication administration: aspirin, epinephrine auto-injector, oral glucose, naloxone, albuterol
• OB emergencies: normal delivery, neonatal care, complications
• Transport decisions: facility selection, ongoing assessment

Domain 3: Scene Size-Up & Safety (15-19%)

• Scene safety: personal safety, hazard identification, BSI/PPE selection
• Mechanism of injury / nature of illness: reading scene clues
• Number of patients & resources: triage and requests for ALS, fire, hazmat, law enforcement
• Standard precautions: infection control and exposure prevention
• Environmental hazards: traffic, weather, structural, chemical, electrical

Domain 4: Operations (10-14%)

• EMS systems & roles: scope of practice, medical direction, quality improvement
• Communication & documentation: radio reports, patient care reports (PCR), handoff
• Legal & ethical: consent, refusal, advance directives, HIPAA, mandatory reporting, DNR
• Mass casualty incidents: START triage, incident command system (ICS)
• Ambulance operations: vehicle and equipment readiness, safe driving
• Hazmat awareness: recognition, isolation, notification (not mitigation)

Domain 5: Secondary Assessment (5-9%)

• History taking: SAMPLE history, OPQRST for pain
• Detailed physical exam: head-to-toe or focused assessment
• Reassessment: trending vitals, intervention effectiveness, status changes
• Glasgow Coma Scale: eye, verbal, motor scoring
• Special tools: stroke scales (Cincinnati, FAST), pediatric assessment triangle

How the Old Domains Map to the New Structure

What This Means for Your Study Plan

The restructure changes how questions are framed, not what you must know. Because Primary Assessment plus Patient Treatment & Transport together make up roughly 60-67% of the exam, the highest-yield use of your time is mastering the assessment-to-intervention pipeline: rapidly forming a general impression, working the ABCs, recognizing immediate life threats, and selecting the correct first intervention. A question that once read "What is the most likely cardiac rhythm?" is now more likely to read "Given this presentation, what should you do next?" — the clinical fact still matters, but it is wrapped in a decision.

The 85% adult / 15% pediatric split tells you where to concentrate volume while not neglecting children. Pediatric items appear in every domain — a choking infant (treatment), a febrile toddler in respiratory distress (primary assessment), a school bus crash with multiple patients (scene size-up). Because children compensate and then crash quickly, pediatric questions disproportionately test early recognition of distress. Practicing the Pediatric Assessment Triangle (appearance, work of breathing, circulation to skin) pays off across the blueprint.

Finally, do not under-prepare the smaller domains. Operations and Secondary Assessment together can be up to 23% of the exam, and they contain easy points for the prepared candidate: SAMPLE/OPQRST history, consent and refusal rules, HIPAA, DNR/POLST handling, and START triage are all rule-based topics that reward simple memorization. Missing them is missing the most predictable questions on the test.
