35 practice questions

1. Public health focuses on:

   1. A. Insurance coverage and access
   2. B. The individual patient in front of you
   3. C. Hospital operations and capacity
   4. D. The health of whole populations
   Show answer

   Answer: D. The health of whole populations

   Public health focuses on the health of populations and communities. EMS works at both levels, patient by patient and community-wide.

2. Epidemiology is the study of:

   1. A. How health care resources are funded
   2. B. How individual diseases are diagnosed
   3. C. Disease patterns in populations
   4. D. How medications act on body systems
   Show answer

   Answer: C. Disease patterns in populations

   Epidemiology studies how disease and injury are distributed in populations and what influences them. Epidemiologic data show EMS where to aim prevention efforts.

3. Primary prevention means:

   1. A. Rehabilitation after an injury
   2. B. Preventing a second incident
   3. C. Keeping an injury or illness from happening at all
   4. D. Stopping an event from getting worse after it starts
   Show answer

   Answer: C. Keeping an injury or illness from happening at all

   Car seat programs and swimming lessons are primary prevention.

4. Treating a patient's chest pain quickly to limit heart damage is an example of:

   1. A. Tertiary prevention
   2. B. Surveillance
   3. C. Primary prevention
   4. D. Secondary prevention
   Show answer

   Answer: D. Secondary prevention

   Secondary prevention limits the damage once an event has begun.

5. Rehabilitation that helps a stroke patient regain function is an example of:

   1. A. Primary prevention
   2. B. Tertiary prevention
   3. C. Secondary prevention
   4. D. Epidemiology
   Show answer

   Answer: B. Tertiary prevention

   Tertiary prevention reduces long-term disability.

6. A teachable moment is:

   1. A. The receptive window right after an event
   2. B. A crew debrief right after a difficult call
   3. C. A scheduled public safety lecture at a school
   4. D. A monthly in-service training day for crews
   Show answer

   Answer: A. The receptive window right after an event

   It is the point right after an event when a patient or family is most receptive to safety advice. A near-miss fall or crash opens a short window where advice lands.

7. Which is an example of EMS-led injury prevention?

   1. A. Car seat inspections and helmet programs
   2. B. Rapid transport to a designated trauma center
   3. C. Revising the trauma triage protocol each year
   4. D. Advanced airway skills training for all crews
   Show answer

   Answer: A. Car seat inspections and helmet programs

   Car seat inspections, fall risk assessments, and helmet programs are EMS-led prevention. Prevention avoids the injuries that transport can only respond to.

8. Data that EMS agencies contribute to state and national databases such as NEMSIS are used to:

   1. A. Identify trends and target improvements
   2. B. Certify agencies for federal funding
   3. C. Rank individual providers by performance
   4. D. Bill Medicare for each transport
   Show answer

   Answer: A. Identify trends and target improvements

   The data identify trends and target prevention and system improvements. Good documentation makes that data useful. NEMSIS is a data standard, not a funding certification or a billing system.

9. A community needs assessment helps an EMS agency:

   1. A. Set response time goals for the system
   2. B. Decide which new ambulance models to purchase
   3. C. Identify local health and injury problems
   4. D. Determine how many new staff to hire
   Show answer

   Answer: C. Identify local health and injury problems

   It identifies the specific health and injury problems in the area so programs can target them. What works in a rural county may not fit an urban neighborhood.

10. Years of productive life lost is a measure that:

    1. A. Weighs early deaths more heavily
    2. B. Counts EMS responses for each injury type
    3. C. Counts only deaths over age 65
    4. D. Measures total hospital costs of injury
    Show answer

    Answer: A. Weighs early deaths more heavily

    It weighs the impact of deaths that occur early in life, which highlights injury as a public health problem. Injury kills the young disproportionately, which this measure makes visible.

11. The connection between EMS and public health is strongest in:

    1. A. Ambulance and medical equipment design
    2. B. Prevention, surveillance, and outreach
    3. C. Dispatch protocols and call-taking
    4. D. Billing and reimbursement for transports
    Show answer

    Answer: B. Prevention, surveillance, and outreach

    The connection is strongest in prevention, surveillance, and access to care for vulnerable populations. EMS sees the community where it lives.

12. Which is an example of EMS surveillance data in action?

    1. A. Mapping overdoses to target naloxone
    2. B. Fleet maintenance and fuel use reports
    3. C. Monthly response time compliance reports
    4. D. Staffing levels and overtime data
    Show answer

    Answer: A. Mapping overdoses to target naloxone

    Tracking overdose calls by neighborhood lets agencies target naloxone distribution. Field documentation makes this possible.

13. Primary prevention aimed at falls might include:

    1. A. Rehabilitation after a hip fracture repair
    2. B. Hip protectors after a first hip fracture
    3. C. Rapid transport after an older adult falls
    4. D. Home hazard checks and balance classes
    Show answer

    Answer: D. Home hazard checks and balance classes

    Preventing the first fall is the goal.

14. Secondary prevention in stroke care involves:

    1. A. Public education about risk factors
    2. B. Smoking cessation programs
    3. C. Rehabilitation after a stroke
    4. D. Rapid recognition and transport
    Show answer

    Answer: D. Rapid recognition and transport

    Rapid recognition and transport allow time-sensitive treatment. Secondary prevention limits damage once the event begins.

15. Which activity best illustrates tertiary prevention?

    1. A. Cardiac rehabilitation after an MI
    2. B. Car seat checks at fire stations
    3. C. Helmet distribution to children
    4. D. Annual influenza vaccination
    Show answer

    Answer: A. Cardiac rehabilitation after an MI

    It reduces long-term disability and recurrence.

16. Injury prevention programs work best when they:

    1. A. Target every resident in the area equally
    2. B. Use local data and combined strategies
    3. C. Focus only on public education campaigns
    4. D. Rely on a single large public safety event
    Show answer

    Answer: B. Use local data and combined strategies

    Effective programs use local data, target a specific risk, and combine education, enforcement, and engineering. Combined strategies outperform education alone.

17. Which is an example of an engineering or environmental prevention strategy?

    1. A. Safer highway and vehicle design
    2. B. Public safety media campaigns
    3. C. Seat belt and helmet laws
    4. D. School-based safety education
    Show answer

    Answer: A. Safer highway and vehicle design

    Improved highway design and vehicle crashworthiness are engineering strategies. They protect without requiring behavior change.

18. Enforcement as a prevention strategy works by:

    1. A. Changing the design of products
    2. B. Educating the public about risks
    3. C. Laws with consequences, like DUI laws
    4. D. Providing treatment after injury
    Show answer

    Answer: C. Laws with consequences, like DUI laws

    Enforcement creates consequences that change behavior, such as impaired driving laws. Combined with education it is more effective.

19. A teachable moment for EMS might occur when:

    1. A. While working an active cardiac arrest
    2. B. Right after a fall or near miss
    3. C. During a routine scheduled transfer
    4. D. During routine station and vehicle duties
    Show answer

    Answer: B. Right after a fall or near miss

    The window is brief but powerful.

20. The purpose of community risk reduction programs is to:

    1. A. Lower the agency's exposure to legal liability
    2. B. Reduce the number of staff each shift needs
    3. C. Reduce incidence and severity of emergencies
    4. D. Improve unit response times across the area
    Show answer

    Answer: C. Reduce incidence and severity of emergencies

    Fire services have long used this model. Lower liability can be a side effect, but the aim is fewer and less severe emergencies.

21. EMS can contribute to vaccination efforts by:

    1. A. Staffing clinics and educating patients
    2. B. Referring patients to hospitals for vaccines
    3. C. Tracking vaccine supply for local hospitals
    4. D. Only transporting patients to vaccine clinics
    Show answer

    Answer: A. Staffing clinics and educating patients

    EMS can staff clinics, educate patients, and in some systems administer vaccines. This expanded during recent public health emergencies.

22. Community paramedicine programs typically target:

    1. A. Frequent 911 users and chronic disease
    2. B. Pediatric patients with acute illness only
    3. C. High-acuity trauma patients after a crash
    4. D. Interfacility critical care transfer patients
    Show answer

    Answer: A. Frequent 911 users and chronic disease

    Programs target frequent users of 911, recently discharged patients, and those with chronic disease. Goals include reducing avoidable readmissions.

23. Which is a measurable outcome of a successful prevention program?

    1. A. Amount of local media coverage
    2. B. Lower rate of the targeted injury
    3. C. Number of brochures handed out
    4. D. Attendance at a safety event
    Show answer

    Answer: B. Lower rate of the targeted injury

    Outputs are not outcomes.

24. Social determinants of health that EMS commonly observes include:

    1. A. Housing, food access, and isolation
    2. B. Age, biological sex, and family history
    3. C. Genetic risk for heart disease and stroke
    4. D. Chronic disease diagnoses and medications
    Show answer

    Answer: A. Housing, food access, and isolation

    Housing conditions, food availability, isolation, and access to medication are social determinants EMS often sees. Documenting them supports referrals.

25. A paramedic who notices a patient cannot afford medications should:

    1. A. Document it and connect them to resources
    2. B. Transport so the ED can refill the medication
    3. C. Say nothing, since it is not medical
    4. D. Note it in the chart and take no other step
    Show answer

    Answer: A. Document it and connect them to resources

    Document it and connect the patient with social work or community resources. Nonadherence often reflects cost, not choice. The ED is not a pharmacy, and documenting without a referral leaves the cost barrier in place.

26. Which population is most at risk during extreme heat?

    1. A. Healthy young adults
    2. B. Middle-aged adults who exercise
    3. C. Older adults and the chronically ill
    4. D. School-age children
    Show answer

    Answer: C. Older adults and the chronically ill

    Older adults, those with chronic illness, and people without cooling are most at risk. Wellness checks are a public health role.

27. Surveillance of EMS data was valuable during the opioid crisis because it:

    1. A. Reduced overall 911 call volume quickly
    2. B. Revealed overdose clusters quickly
    3. C. Confirmed the drugs involved in each death
    4. D. Replaced medical examiner death data
    Show answer

    Answer: B. Revealed overdose clusters quickly

    It provided near real-time information about overdose clusters. Data drove naloxone distribution programs. EMS records cannot confirm which drugs were involved; toxicology and medical examiner data still do that.

28. A community health needs assessment should include:

    1. A. Only the agency's own EMS run data
    2. B. Only hospital discharge and billing data
    3. C. Many data sources and community input
    4. D. Only community opinion survey results
    Show answer

    Answer: C. Many data sources and community input

    It should include demographic, health, and injury data from multiple sources with community input. Partnership improves both accuracy and buy-in.

29. Which is a barrier to EMS involvement in prevention?

    1. A. Laws prohibiting EMS from prevention work
    2. B. Lack of community need for prevention work
    3. C. Payment models that fund only transport
    4. D. Lack of any useful data from EMS charts
    Show answer

    Answer: C. Payment models that fund only transport

    Funding models pay for transport rather than prevention, and time is limited. Some systems have found grant and partner funding.

30. EMS providers serve as role models for health behavior, which means:

    1. A. Personal habits are entirely a private matter
    2. B. Their habits affect their credibility
    3. C. It applies only while they are on duty
    4. D. It matters only for designated public educators
    Show answer

    Answer: B. Their habits affect their credibility

    Their own habits affect the credibility of the advice they give. Communities notice.

31. Which describes EMS involvement in disaster public health?

    1. A. It is solely a hospital function
    2. B. It ends once patients are transported
    3. C. Surveillance, triage, prophylaxis, messaging
    4. D. It is limited to trauma care
    Show answer

    Answer: C. Surveillance, triage, prophylaxis, messaging

    It includes surveillance, triage, mass prophylaxis, and public messaging. Planning determines effectiveness.

32. A hazard vulnerability assessment helps an agency:

    1. A. Set daily unit posting by call volume
    2. B. Score how well crews performed in a drill
    3. C. Identify likely disasters to plan for
    4. D. Estimate the cost of each past disaster
    Show answer

    Answer: C. Identify likely disasters to plan for

    Coastal and inland systems face different risks. Daily posting is system status management and drill scoring is exercise evaluation; the assessment looks forward at likely hazards rather than pricing past events.

33. The value of EMS data in prevention work depends most on:

    1. A. Total volume of calls
    2. B. The agency's annual budget
    3. C. Accurate, complete documentation
    4. D. Average response times
    Show answer

    Answer: C. Accurate, complete documentation

    Poor charts produce useless data.

34. Health literacy affects patients by:

    1. A. Setting the priority of their EMS response
    2. B. Affecting whether they follow instructions
    3. C. Determining their insurance coverage options
    4. D. Changing how their diseases physically present
    Show answer

    Answer: B. Affecting whether they follow instructions

    Health literacy influences whether patients understand instructions, medications, and when to seek care. Plain language and teach-back improve it.

35. Which is the most appropriate EMS response to repeated calls from one household?

    1. A. Document less detail on the repeat calls
    2. B. Refuse transport on all of their future calls
    3. C. Look for causes and involve resources
    4. D. Reduce the level of service sent there
    Show answer

    Answer: C. Look for causes and involve resources

    Investigate underlying causes and involve community resources. Repeat calls often signal unmet needs.
