   Answer: B. NHTSA, within the Department of Transportation

   The National Highway Traffic Safety Administration has led EMS standards since the 1966 Highway Safety Act.

2. A system that helps dispatchers choose the right units and coach callers before EMS arrives is:

   1. A. Online medical direction
   2. B. Tiered response dispatching
   3. C. Emergency medical dispatch
   4. D. Mutual aid agreements
   Show answer

   Answer: C. Emergency medical dispatch

   Trained emergency medical dispatchers use structured call-taking cards.

3. Pre-arrival instructions are:

   1. A. Advance notifications sent to the receiving hospital
   2. B. Care instructions a dispatcher gives the caller
   3. C. Driving directions the dispatcher gives the crew
   4. D. Standing orders the medical director issues to crews
   Show answer

   Answer: B. Care instructions a dispatcher gives the caller

   They are care instructions the dispatcher gives the caller before EMS arrives. Dispatcher-coached CPR is a well-studied example that improves survival.

4. In a tiered response system:

   1. A. BLS or ALS units are sent based on call severity
   2. B. Only ALS units respond to any medical call
   3. C. Every call receives the same BLS and ALS response
   4. D. Fire units handle every call before an ambulance
   Show answer

   Answer: A. BLS or ALS units are sent based on call severity

   BLS and ALS units are dispatched according to the severity of the call. Tiering matches resources to need and keeps ALS units available for critical calls.

5. Mutual aid is:

   1. A. A public campaign teaching residents when to call 911 for help
   2. B. A federal grant program for rural EMS agencies
   3. C. A form of online medical direction between doctors
   4. D. An agreement among agencies to assist when overwhelmed
   Show answer

   Answer: D. An agreement among agencies to assist when overwhelmed

   Agencies agree to help each other when local resources are overwhelmed. Mutual aid agreements are arranged in advance, not during the emergency.

6. A 911 system that automatically shows the caller's phone number and location is called:

   1. A. Basic 911
   2. B. Enhanced 911
   3. C. A tiered system
   4. D. Mutual aid
   Show answer

   Answer: B. Enhanced 911

   Enhanced 911 helps dispatchers send help even when a caller can't speak or give an address.

7. A designated trauma center differs from other hospitals because it:

   1. A. Has surgical teams and resources ready around the clock
   2. B. Charges patients less for emergency trauma care
   3. C. Is always the closest hospital to the injury scene
   4. D. Accepts injured patients only when they arrive by air transport
   Show answer

   Answer: A. Has surgical teams and resources ready around the clock

   A trauma center has the staff, equipment, and surgical capability available at all times for severely injured patients. Designation is based on that readiness, verified by review.

8. Which of these is a specialty receiving center?

   1. A. An urgent care clinic
   2. B. A stroke center
   3. C. A physician's office
   4. D. A nursing home
   Show answer

   Answer: B. A stroke center

   Burn, stroke, cardiac, pediatric, and hyperbaric centers are other examples.

9. Community paramedicine and mobile integrated health care programs are designed to:

   1. A. Increase the number of billable patient transports
   2. B. Replace home health nurses in the community
   3. C. Respond only to high-acuity trauma calls
   4. D. Reduce avoidable emergency department visits
   Show answer

   Answer: D. Reduce avoidable emergency department visits

   These programs meet patients' health needs in the community and reduce avoidable emergency department visits. Providers may do home visits, follow-ups, and chronic disease checks instead of transporting.

10. Which best describes the paramedic's place in health care?

    1. A. A public safety officer with medical training
    2. B. A hospital employee assigned to field duty in every case
    3. C. An independent clinician who needs no oversight
    4. D. An extension of the physician's care into the field
    Show answer

    Answer: D. An extension of the physician's care into the field

    Paramedics practice under a physician medical director's authority.

11. EMS systems are most commonly funded by:

    1. A. Federal EMS grants that cover all operating costs
    2. B. Donations from local hospitals and health systems
    3. C. Patient billing alone, with no tax support
    4. D. A mix of billing, tax revenue, and subsidies
    Show answer

    Answer: D. A mix of billing, tax revenue, and subsidies

    Funding usually combines insurance, Medicare and Medicaid billing, taxes, and local subsidies. Reimbursement has historically been tied to transport, which is changing slowly. Federal grants cover a small share of costs, hospitals rarely fund EMS, and billing by itself seldom pays for round-the-clock readiness, so most systems also need tax support.

12. The main purpose of an EMS system's evaluation component is to:

    1. A. Build crew staffing schedules for each shift
    2. B. Measure performance and find ways to improve
    3. C. Identify employees for disciplinary action
    4. D. Set billing rates for each type of response
    Show answer

    Answer: B. Measure performance and find ways to improve

    Response times, clinical outcomes, and patient satisfaction are all measured.

13. The first link in most emergency response systems is:

    1. A. The hospital preparing to receive the patient
    2. B. A bystander recognizing the emergency and calling
    3. C. The dispatcher answering and triaging the call
    4. D. The first paramedic arriving on scene to begin assessment
    Show answer

    Answer: B. A bystander recognizing the emergency and calling

    The public must recognize an emergency and call for help. Public education shortens that delay.

14. Public access to EMS depends on:

    1. A. Available emergency department capacity nearby
    2. B. Having an ambulance available at all times
    3. C. The caller having health insurance coverage
    4. D. Knowing when to call and a working 911 system
    Show answer

    Answer: D. Knowing when to call and a working 911 system

    Access depends on knowing how and when to call, and on a working communication system. Language and disability access matter too.

15. Emergency medical dispatchers use structured protocols to:

    1. A. Hold response until a supervisor approves the call
    2. B. Ask set questions, prioritize, and coach callers
    3. C. Choose the destination hospital for each patient
    4. D. Assign billing codes and insurance information
    Show answer

    Answer: B. Ask set questions, prioritize, and coach callers

    Protocols have dispatchers ask consistent questions, assign priority, and provide pre-arrival instructions. Consistency is what makes the triage reliable.

16. Dispatcher-assisted CPR has been shown to:

    1. A. Increase bystander CPR rates and improve survival
    2. B. Confuse untrained callers and lower CPR quality
    3. C. Have no measurable effect on cardiac arrest survival
    4. D. Delay EMS arrival by keeping callers on the line
    Show answer

    Answer: A. Increase bystander CPR rates and improve survival

    It is a measured performance standard in many systems.

17. Priority dispatch allows a system to:

    1. A. Send every available unit to every call it receives
    2. B. Match response level and speed to call severity
    3. C. Eliminate BLS units in favor of all-ALS staffing
    4. D. Refuse transport for all low-priority 911 callers
    Show answer

    Answer: B. Match response level and speed to call severity

    It preserves ALS resources for critical patients.

18. First responders in a tiered system serve to:

    1. A. Handle trauma calls while ALS handles medical
    2. B. Start care while the ambulance is en route
    3. C. Transport stable patients in their own vehicles
    4. D. Replace transporting ambulances on most calls
    Show answer

    Answer: B. Start care while the ambulance is en route

    First responders begin care quickly while the transporting unit is en route. Police and fire units often fill this role.

19. System status management refers to:

    1. A. Scheduling crews for each shift and station
    2. B. Managing billing status for each transport
    3. C. Posting units based on predicted demand
    4. D. Tracking vehicle maintenance and readiness
    Show answer

    Answer: C. Posting units based on predicted demand

    System status management positions units based on predicted call demand by time and location. It aims to shorten response times.

20. A benefit of regionalized specialty care is that:

    1. A. Costs fall for every patient and hospital
    2. B. Transport times become shorter for everyone
    3. C. Every hospital offers every specialty service
    4. D. Time-critical patients go to experienced centers
    Show answer

    Answer: D. Time-critical patients go to experienced centers

    Patients with time-critical conditions go to facilities that handle them frequently and well. Volume and readiness improve outcomes.

21. Trauma system development is based on the principle that:

    1. A. Severely injured patients do better at trauma centers
    2. B. Ground transport is always better than air medical transport
    3. C. All hospitals provide equal care for major injuries
    4. D. Transport time does not affect trauma outcomes
    Show answer

    Answer: A. Severely injured patients do better at trauma centers

    Triage criteria guide the destination decision.

22. A Level I trauma center differs from a Level III by:

    1. A. Offering full subspecialty care, research, and teaching
    2. B. Operating without a general emergency department
    3. C. Being located closer to most rural injury scenes
    4. D. Accepting fewer patients with complex injuries
    Show answer

    Answer: A. Offering full subspecialty care, research, and teaching

    A Level I center has full surgical subspecialty coverage plus research and education programs. Level designations describe capability.

23. Stroke center designation matters because:

    1. A. Time-dependent therapy needs imaging and specialists
    2. B. Stroke cannot be treated once symptoms begin
    3. C. It shortens ambulance transport times to any hospital
    4. D. All hospitals already have neurologists on site
    Show answer

    Answer: A. Time-dependent therapy needs imaging and specialists

    Prehospital notification speeds the process.

24. Cardiac receiving centers are designated based on:

    1. A. Around-the-clock cath lab capability
    2. B. Contracts held with local ambulance services
    3. C. Distance from the center of the service area
    4. D. Number of inpatient cardiology beds available
    Show answer

    Answer: A. Around-the-clock cath lab capability

    Designation depends on availability of percutaneous coronary intervention (PCI) and the team to perform it at any hour. Field ECG transmission shortens door-to-balloon times.

25. Pediatric receiving facilities are important because:

    1. A. Adults cannot be treated at these facilities
    2. B. They are usually closer than adult hospitals
    3. C. Children are transported more often than adults
    4. D. Children need special equipment, dosing, and skill
    Show answer

    Answer: D. Children need special equipment, dosing, and skill

    Pediatric emergencies require specific equipment, medication dosing, and experience. Not every emergency department is prepared.

26. Burn centers provide:

    1. A. Trauma surgery but no burn rehabilitation
    2. B. Resuscitation, surgery, and rehab for major burns
    3. C. Outpatient dressing changes for minor burns only
    4. D. Ground and air transport for burn patients
    Show answer

    Answer: B. Resuscitation, surgery, and rehab for major burns

    Burn centers provide specialized resuscitation, surgical, and rehabilitation care for significant burns. Transfer criteria are well defined.

27. Interfacility transport exists to:

    1. A. Take patients home after ED discharge
    2. B. Avoid the 911 system for sick hospital patients
    3. C. Lower costs by moving patients to cheaper beds
    4. D. Move patients to a needed higher level of care
    Show answer

    Answer: D. Move patients to a needed higher level of care

    Interfacility transport moves patients to facilities offering a level of care the sending facility cannot provide. Crew capability must match patient needs. A ride home after discharge is a non-emergency transport, not a transfer between facilities.

28. Medical oversight is considered a required component of an EMS system because:

    1. A. It significantly lowers system operating costs
    2. B. Providers practice under physician authority
    3. C. Federal law requires a physician on scene
    4. D. It shortens response times on critical calls
    Show answer

    Answer: B. Providers practice under physician authority

    Prehospital providers practice medicine under physician authority. Without it, there is no legal basis for practice.

29. Continuing education is a system component because it:

    1. A. Fills the hours required on a renewal form
    2. B. Satisfies liability insurance carrier requirements
    3. C. Maintains competence and brings in new evidence
    4. D. Guarantees pay increases for completed hours
    Show answer

    Answer: C. Maintains competence and brings in new evidence

    Skills decay without practice.

30. System evaluation typically measures:

    1. A. Vehicle mileage, fuel use, and repair costs
    2. B. Response times as the only meaningful measure
    3. C. Employee attendance, overtime, and sick leave
    4. D. Outcomes, compliance, intervals, and experience
    Show answer

    Answer: D. Outcomes, compliance, intervals, and experience

    Evaluation typically measures clinical outcomes, protocol compliance, response intervals, and patient experience. Outcome measures matter most.

31. Public information and education programs serve to:

    1. A. Teach residents to treat emergencies without calling
    2. B. Advertise the agency to attract new members
    3. C. Teach when to call and what to do until EMS arrives
    4. D. Certify residents as emergency medical responders
    Show answer

    Answer: C. Teach when to call and what to do until EMS arrives

    CPR and bleeding control training are examples. Public education adds to an EMS response rather than replacing it, and it raises awareness rather than certifying responders. Recruiting members is a separate goal.

32. Disaster preparedness as a system component requires:

    1. A. Federal approval before any local plan takes effect
    2. B. Planning, training, mutual aid agreements, and exercises
    3. C. Dedicated hospital funding for surge capacity
    4. D. Additional reserve ambulances and stockpiled supplies
    Show answer

    Answer: B. Planning, training, mutual aid agreements, and exercises

    Plans that are never exercised fail.

33. Integration of health services means EMS should:

    1. A. Link with public health, primary care, and social services
    2. B. Operate independently from other health services
    3. C. Focus strictly on emergency transport to hospitals
    4. D. Route patients away from hospitals whenever possible
    Show answer

    Answer: A. Link with public health, primary care, and social services

    EMS should connect with public health, primary care, and social services as part of the larger health system. Patients often need services rather than an emergency department.

34. Communications interoperability is important because:

    1. A. Dispatch centers require it for call recording
    2. B. It speeds billing between neighboring agencies
    3. C. It lowers radio purchase and maintenance costs
    4. D. Agencies must talk to each other in big incidents
    Show answer

    Answer: D. Agencies must talk to each other in big incidents

    Agencies from different disciplines must be able to talk during large incidents. Incompatible radio systems have contributed to disasters.

35. Which measure most directly reflects EMS clinical quality?

    1. A. Survival to discharge after cardiac arrest
    2. B. Average age and mileage of the ambulance fleet
    3. C. Average response time to high-priority calls
    4. D. Total number of patients transported per year
    Show answer

    Answer: A. Survival to discharge after cardiac arrest

    Survival to hospital discharge after cardiac arrest is an outcome measure. Outcome measures are the meaningful test.

36. Ambulance deployment strategies aim to:

    1. A. Balance coverage, response time, and crew fatigue
    2. B. Reduce staffing to the minimum allowed by law
    3. C. Keep each unit parked at its assigned home station
    4. D. Eliminate the need for first responder units
    Show answer

    Answer: A. Balance coverage, response time, and crew fatigue

    Excessive posting contributes to fatigue. Fixed station posting ignores how demand shifts by hour and place, cutting staff lengthens responses, and first responders still bridge the gap before an ambulance arrives.

37. A community risk assessment helps an EMS system:

    1. A. Set response time targets for each type of medical call
    2. B. Review the quality of care on past calls
    3. C. Target resources to local hazards and at-risk groups
    4. D. Increase staffing equally across every district
    Show answer

    Answer: C. Target resources to local hazards and at-risk groups

    It identifies hazards and populations at risk so resources and prevention can be targeted. Rural and urban risks differ greatly. Response time targets come from system performance standards, and reviewing past care is quality improvement; neither is the purpose of a risk assessment. Spreading staff equally ignores where the risk actually is.

38. Which describes a benefit of a well-integrated EMS system?

    1. A. Seamless care from the call to definitive treatment
    2. B. More separate agencies responding to every call
    3. C. Fewer handoffs because a single agency does everything
    4. D. Longer scene times for more complete assessments
    Show answer

    Answer: A. Seamless care from the call to definitive treatment

    Gaps between components are where patients are lost.

39. Reimbursement models that pay only for transport create a problem because:

    1. A. They violate federal anti-kickback regulations
    2. B. They reduce call volume by deterring callers
    3. C. They pay agencies more than the cost of transport
    4. D. They discourage non-transport care that may help more
    Show answer

    Answer: D. They discourage non-transport care that may help more

    Paying only for transport discourages treat-and-refer and community paramedicine programs that may serve patients better. Payment reform is an ongoing effort.

40. Medical dispatch priority cards help ensure:

    1. A. Fewer repeat calls from the same callers
    2. B. Consistent questioning by every dispatcher
    3. C. Faster billing and insurance processing
    4. D. Every call receives the same level of response
    Show answer

    Answer: B. Consistent questioning by every dispatcher

    Cards ensure consistent questioning regardless of which dispatcher answers. Consistency improves both safety and data.

41. Critical care transport crews typically include:

    1. A. Critical care paramedics or nurses
    2. B. Any available EMT and driver on the schedule
    3. C. A physician on every critical care transport
    4. D. Registered nurses only, with no paramedics
    Show answer

    Answer: A. Critical care paramedics or nurses

    Crews include providers with additional training, such as critical care paramedics or flight nurses. They manage ventilators, infusions, and invasive monitoring.

42. EMS participation in the health care system as a whole has grown to include:

    1. A. Prevention, care navigation, and follow-up
    2. B. Only scene trauma care and rapid transport
    3. C. Only 911 emergency response and transport
    4. D. Only interfacility transport between hospitals
    Show answer

    Answer: A. Prevention, care navigation, and follow-up

    In some systems EMS now includes prevention, navigation to appropriate care, and follow-up. EMS Agenda 2050 anticipates further growth.
