Sample Practice Questions

Try these 10 sample questions from the National Registry Emergency Medical Responder (EMR) Certification Examination practice bank. Each includes the answer and explanation. Continue with the interactive practice above to review the full question set.

  1. 1Before reaching a reported chemical spill on level ground, an EMR learns that wind is blowing steadily from west to east. Which approach keeps the crew upwind?

    1. A. Approach from the north.
    2. B. Approach from the south.
    3. C. Approach from the west.
    4. D. Approach from the east.

    Answer: C

    Explanation: The ERG directs responders to "APPROACH CAUTIOUSLY FROM UPWIND, UPHILL AND/OR UPSTREAM". Wind from the west reaches the spill from the west, making that the upwind approach.

    Reference: 2024 Emergency Response Guidebook — Safety Precautions, p. 4

  2. 2Several occupants of a house have headache and nausea without fever after a power outage. Which shared exposure should an EMR specifically investigate?

    1. A. Carbon monoxide
    2. B. Carbon dioxide
    3. C. Nitrogen dioxide
    4. D. Hydrogen sulfide

    Answer: A

    Explanation: "Consider CO poisoning especially in these situations: No fever associated with symptoms, history of exposure, multiple patients with similar complaints." The cluster and outage suggest a shared combustion-related CO exposure, rather than an isolated illness.

    Reference: Clinical Guidance for Carbon Monoxide Poisoning Following Disasters and Severe Weather — How to Recognize CO Poisoning

  3. 3During the focused examination of an injured extremity, an EMR checks distal pulses, skin color, and capillary refill. Which assessment component do these findings primarily describe?

    1. A. Movement
    2. B. Sensation
    3. C. Symmetry
    4. D. Circulation

    Answer: D

    Explanation: "circulation a) pulses b) color c) capillary refill" is the original extremity circulation sublist. Movement, sensation, and symmetry are separately listed components.

    Reference: National EMS Education Standards: Emergency Medical Responder Instructional Guidelines — Page 51 — Secondary Assessment, Extremity Circulation

  4. 4An unresponsive trauma patient's airway remains obstructed despite a jaw thrust with manual cervical stabilization. Which maneuver does the EMR guideline identify as the next airway-opening attempt?

    1. A. Head-tilt/chin-lift
    2. B. Abdominal thrusts
    3. C. Recovery-position roll
    4. D. Cricoid pressure

    Answer: A

    Explanation: "If airway is not open and jaw thrust maneuver does not open it, use head tilt/chin lift maneuver" An ineffective jaw thrust must not leave the airway obstructed; the guideline calls for head-tilt/chin-lift.

    Reference: National EMS Education Standards: Emergency Medical Responder Instructional Guidelines — Page 31 — Airway Management, Failed Jaw Thrust

  5. 5A reusable semicritical patient-care device is being reprocessed. Which named stage must remove organic material before high-level disinfection?

    1. A. Drying
    2. B. Cleaning
    3. C. Packaging
    4. D. Sterilization

    Answer: B

    Explanation: "Remove organic material from critical and semi-critical instrument/devices, using recommended cleaning agents before high level disinfection and sterilization" requires cleaning first. Drying and packaging do not remove the organic soil, and sterilization is not the preliminary cleaning stage.

    Reference: Guideline for Isolation Precautions: Summary of Recommendations — Standard Precautions, IV.E.2

  6. 6While responding to a tanker crash, an EMR receives the cargo's four-digit UN identification number. Which ERG section should the EMR search first to locate the response guide?

    1. A. The yellow identification-number pages
    2. B. The blue alphabetical material pages
    3. C. The orange response-guide pages
    4. D. The green protective-distance pages

    Answer: A

    Explanation: The ERG identifies a "4-digit identification number, UN or NA (go to yellow section)". The known UN number is the entry into the yellow index; the other sections organize names, response guidance, or protective distances.

    Reference: 2024 Emergency Response Guidebook — Shipping Papers, inside front cover; How to Use This Guidebook, p. 1

  7. 7A frightened adult asks who an approaching EMR is. Which information should the EMR give first to establish identity and the purpose of the encounter?

    1. A. The working diagnosis and the patient's symptom severity
    2. B. The transport destination and the proposed ambulance route
    3. C. The responder's identity and explanation of being there to help
    4. D. The initial examination findings and the patient's prior history

    Answer: C

    Explanation: "EMR should explain that he or she is there to help" Introducing the responder and purpose establishes the initial relationship before a detailed clinical or administrative discussion.

    Reference: National EMS Education Standards: Emergency Medical Responder Instructional Guidelines — Page 44 — Primary Assessment, Initial Patient Contact

  8. 8During a focused examination, an EMR gently feels an injured area for tenderness and swelling. Which examination technique is this?

    1. A. Inspection
    2. B. Palpation
    3. C. Auscultation
    4. D. Percussion

    Answer: B

    Explanation: "Inspect (look) and palpate (feel) for the following signs of injury" Feeling the tissues is palpation; inspection is looking, auscultation is listening, and percussion uses tapping.

    Reference: National EMS Education Standards: Emergency Medical Responder Instructional Guidelines — Page 50 — Secondary Assessment, Inspection and Palpation

  9. 9An EMR is assisting a spontaneously breathing patient's inadequate respirations with a bag-mask. When should the EMR initially squeeze the bag to coordinate with the patient?

    1. A. As the patient finishes exhaling
    2. B. As the patient begins to inhale
    3. C. Halfway through the patient's exhalation
    4. D. During the pause after each exhalation

    Answer: B

    Explanation: "squeeze the bag each time the patient begins to inhale" Assistance is initially synchronized with the patient's inspiratory effort.

    Reference: National EMS Education Standards: Emergency Medical Responder Instructional Guidelines — Page 38 — Artificial Ventilation, Assisting Spontaneous Breathing

  10. 10After care of a patient suspected of VHF, an EMR must contain a reusable contaminated blood-pressure cuff for cleaning or disposal. Which container category does CDC specify?

    1. A. A sharps disposal container
    2. B. A pharmaceutical-waste container
    3. C. A labeled biohazard bag
    4. D. A reusable instrument cassette

    Answer: C

    Explanation: "Contaminated reusable patient care equipment (such as glucometer, blood pressure cuff) should be placed in biohazard bags and labeled for cleaning and disinfection or disposal" directly identifies the container for this device. The other genuine medical containers serve different material categories.
