22 EMS Operations Practice Questions & Answers

1. 1. At a mass-casualty incident using START triage, an adult who cannot walk is breathing 24 times per minute, has no palpable radial pulse, and follows commands. Which triage category applies?

   • A.Expectant (Black)
   • B.Delayed (Yellow)
   • C.Immediate (Red)✓ Answer
   • D.Minor (Green)

   START screens Respiration, Perfusion, and Mental status in order (30-2-can do). The respiratory rate passes (under 30), but an absent radial pulse indicates failed perfusion, which by itself makes the patient Immediate (Red) — mental status is not even reached once perfusion fails.

2. 2. During JumpSTART triage after a school bus crash, a small child is not breathing but has a palpable pulse. What should the triage officer do next?

   • A.Tag the child Expectant and move on
   • B.Move the child to the treatment area
   • C.Give five rescue breaths, then reassess✓ Answer
   • D.Begin continuous chest compressions

   JumpSTART modifies START because pediatric arrest is usually respiratory in origin: an apneic child who still has a pulse receives five rescue breaths. If breathing resumes, the child is tagged Red (Immediate); if not, Black. An apneic adult in START would simply be tagged Black after one airway repositioning.

3. 3. A paramedic serving as triage officer at an MCI finds a patient with a painful, angulated forearm fracture. What is the correct action?

   • A.Give an analgesic before tagging
   • B.Walk the patient to treatment
   • C.Splint the arm before moving on
   • D.Tag the patient and keep moving✓ Answer

   Triage aims for the greatest good for the greatest number: the triage officer assigns a category and moves on without stopping to treat non-life threats. Only immediate lifesaving interventions (such as tourniquets for massive hemorrhage under SALT) are performed during triage; splinting and analgesia wait for the treatment area.

4. 4. A paramedic unit arrives first at a building collapse with dozens of victims. What should the crew do first?

   • A.Search the rubble for trapped survivors
   • B.Transport the first victims found quickly
   • C.Begin treating the most critical victims
   • D.Establish command and size up the scene✓ Answer

   Under NIMS/ICS, the first-arriving unit establishes incident command, sizes up the scene, and requests resources rather than beginning individual patient care. Committing the only on-scene crew to one patient leaves the whole incident without organization, which ultimately costs more lives than it saves.

5. 5. Under the Incident Command System, an effective span of control means one supervisor directly oversees how many subordinates?

   • A.3 to 7✓ Answer
   • B.8 to 12
   • C.12 to 20
   • D.1 to 2

   NIMS sets the manageable span of control at 3 to 7 subordinates per supervisor, with about 5 considered optimal. Fewer wastes supervisory capacity, while more than 7 exceeds what one person can safely track during a dynamic incident.

6. 6. During a prolonged vehicle extrication, an ICS officer notices a life-threatening structural shift and orders all activity stopped immediately. Which position holds this authority?

   • A.The Planning Chief
   • B.The Logistics Chief
   • C.The Liaison Officer
   • D.The Safety Officer✓ Answer

   The Safety Officer, a member of the command staff, monitors conditions and is the one position empowered to halt unsafe operations immediately, without first routing the order through the incident commander. The liaison, logistics, and planning roles coordinate agencies, resources, and documentation, not on-scene safety stops.

7. 7. On the NFPA 704 diamond posted on a chemical storage tank, which colored section describes the health hazard?

   • A.The red section
   • B.The yellow section
   • C.The blue section✓ Answer
   • D.The white section

   On the NFPA 704 diamond each color has a fixed meaning: blue rates the health hazard, red rates flammability, yellow rates instability/reactivity, and white carries special hazard symbols such as water reactivity. Knowing the color code lets responders judge risk from a distance with binoculars.

   Source: NFPA 704 standard: blue = health, red = flammability, yellow = instability, white = special hazardsReport a problem with this question

8. 8. A tanker truck is leaking an unidentified chemical on a highway. Where should the arriving ambulance stage?

   • A.Downhill and downwind, in the cold zone
   • B.Beside the tanker, in the hot zone
   • C.Uphill and upwind, in the warm zone
   • D.Uphill and upwind, in the cold zone✓ Answer

   Vapors travel downwind and liquids flow downhill, so staging uphill and upwind keeps the crew out of the product's path. EMS providers without hazmat training operate only in the cold zone; the warm zone is the decontamination corridor and the hot zone is the contaminated area, both reserved for trained, protected personnel.

   Source: DOT Emergency Response Guidebook / hazmat zone doctrine: stage upwind, uphill, in the cold zoneReport a problem with this question

9. 9. Dispatch reports a stabbing and the attacker's whereabouts are unknown. What should the paramedic crew do when nearing the address?

   • A.Enter quickly and control the bleeding
   • B.Approach with lights off and slip inside
   • C.Stage at a distance until police secure it✓ Answer
   • D.Park at the door and wait for the patient

   A scene with a potentially armed, unlocated assailant is not safe to enter: injured providers cannot help anyone and add casualties to the incident. The crew stages out of sight of the address and enters only after law enforcement declares the scene secure — and retreats if it becomes unsafe again.

10. 10. Statistically, most ambulance collisions during emergency responses happen in which location?

    • A.On interstate highways
    • B.In hospital parking structures
    • C.At roadway intersections✓ Answer
    • D.On rural two-lane roads

    Intersections concentrate crossing traffic, obstructed sight lines, and drivers who may not hear or heed the siren, so that is where most ambulance crashes occur. This is why emergency vehicle operators must slow or stop and clear every lane of an intersection before proceeding, even with a green light.

11. 11. While responding with lights and siren activated, what do these warning devices legally accomplish for the ambulance operator?

    • A.They compel other drivers to yield
    • B.They exempt the driver from liability
    • C.They authorize any speed necessary
    • D.They request the right-of-way only✓ Answer

    Lights and siren only ask other drivers to yield the right-of-way; they never guarantee it, and some drivers panic or stop suddenly when they hear a siren. The operator remains bound by the 'due regard' standard and stays liable for the consequences of driving that a reasonable, careful driver would not accept.

12. 12. A medical helicopter is en route to a rural crash. What is the recommended minimum landing zone size the ground crew should prepare?

    • A.300 by 300 feet
    • B.100 by 100 feet✓ Answer
    • C.200 by 200 feet
    • D.50 by 50 feet

    A landing zone of roughly 100 by 100 feet gives the rotor system a safe margin from obstacles while remaining achievable at most scenes. The area must also be flat, firm, free of debris and loose objects, and clear of wires, with vehicles and bystanders kept well back.

13. 13. A medical helicopter has landed at the designated LZ. How should the paramedic approach the aircraft?

    • A.From the rear, staying below the tail rotor
    • B.From either side, once the skids touch down
    • C.From the front, only after the pilot signals✓ Answer
    • D.From uphill, crouching beneath the rotors

    The safe approach corridor is from the front, within the pilot's field of view (roughly the 10-to-2 o'clock arc), and only after the pilot or crew signals — crouched, with loose items secured. The tail rotor is nearly invisible when spinning and lethal, and approaching from uphill brings the head closer to the main rotor disk.

14. 14. A 40-year-old is found unresponsive in a park with no relatives present. Under which type of consent does the paramedic provide care?

    • A.Involuntary consent
    • B.Expressed consent
    • C.Informed consent
    • D.Implied consent✓ Answer

    Implied consent applies because the law presumes a reasonable person with an emergency condition would want lifesaving care if able to ask for it. Expressed and informed consent require a patient competent enough to communicate a decision, and involuntary consent applies to persons treated under legal authority, such as those in custody.

15. 15. For a negligence claim against a paramedic to succeed, which complete set of elements must the plaintiff prove?

    • A.Duty, breach, intent, and malice
    • B.Breach, damage, consent, and malice
    • C.Duty, damages, transfer, and intent
    • D.Duty, breach, damages, and causation✓ Answer

    Negligence requires all four elements together: a duty to act, a breach of that duty, real damages, and proximate causation linking the breach to the harm. If any single element is missing — for example, the patient suffered no damages — the claim fails; intent and malice belong to intentional torts, not negligence.

16. 16. A competent adult with chest pain refuses transport after a full explanation of the risks. What should the paramedic do next?

    • A.Ask police to take the patient into custody
    • B.Transport the patient under implied consent
    • C.Leave once the patient promises to call back
    • D.Obtain a signed, witnessed refusal form✓ Answer

    A competent, informed adult has the right to refuse care, so the paramedic documents an informed refusal: capacity assessment, risks explained, medical direction involved per protocol, the patient's signature, and a witness. Transporting against a competent refusal is battery and false imprisonment; leaving with only a verbal promise leaves no legal record.

17. 17. A gunshot patient's shirt must be removed at a crime scene. Which action correctly balances patient care and evidence preservation?

    • A.Leave the clothing on until the hospital
    • B.Cut around, not through, the bullet hole✓ Answer
    • C.Delay all care until police photograph it
    • D.Cut directly through the bullet hole

    Patient care always precedes evidence preservation, but providers should disturb evidence as little as care allows: bullet and knife holes in clothing are themselves evidence, so cut around them, note original positions, and turn clothing over to police. Waiting for photographs or leaving clothing in place delays assessment of the wounds.

18. 18. While completing a paper PCR, a paramedic writes the wrong medication dose. How should the error be corrected?

    • A.Shred the paper form and write a new report
    • B.Cover the entry with fluid and rewrite it
    • C.Erase the entry completely and rewrite it
    • D.Line through it once, correct, and initial✓ Answer

    The original entry must remain legible to show the record was corrected, not concealed: draw a single line through the error, write the correction beside it, and add initials and the date. Erasing, obliterating, or destroying the record looks like falsification, which can cost the paramedic certification and licensure.

19. 19. Which element does NOT belong in the paramedic's radio report to the receiving hospital?

    • A.The patient's chief complaint
    • B.The estimated time of arrival
    • C.The patient's response to care
    • D.The paramedic's personal opinions✓ Answer

    The radio report is a concise, objective handoff — unit ID, ETA, patient age and sex, chief complaint, pertinent history, key findings, treatment given, and the response to that treatment. Personal opinions and subjective conclusions are excluded because radio traffic is not private and speculation can bias care and create liability.

20. 20. A paramedic gives aspirin for chest pain using a written protocol, without calling a physician. This is an example of which type of authority?

    • A.Expanded scope of practice
    • B.Independent practice authority
    • C.Off-line medical direction✓ Answer
    • D.On-line medical direction

    Standing orders and written protocols are off-line (indirect) medical direction: the medical director authorizes specified interventions in advance, so no real-time physician contact is needed. On-line (direct) medical direction means orders received by radio or phone during the call; paramedics always operate under physician delegation, never independently.

21. 21. A team leader orders '1 mg epinephrine IV.' The team member repeats back '1 mg epinephrine IV' before giving it. This exchange is an example of what?

    • A.On-line medical direction
    • B.Closed-loop communication✓ Answer
    • C.Span-of-control management
    • D.Standing-order verification

    Closed-loop communication — order given, repeated back, and confirmed — is a core crew resource management tool because it catches misheard drugs and doses before they reach the patient. It is a team practice between crew members, not a physician order channel or an ICS structural concept.

22. 22. A CQI review identifies a paramedic's repeated intubation errors. What is the primary purpose of the CQI process?

    • A.To protect agencies from legal liability
    • B.To discipline the provider involved
    • C.To find and fix system-level weaknesses✓ Answer
    • D.To rank crews for shift assignments

    Continuous quality improvement is an ongoing, non-punitive cycle: it reviews cases to find weaknesses in the system — training gaps, protocol problems, equipment issues — and fixes them, for example with remediation and skills practice. Treating it as discipline drives providers to hide errors, which defeats the entire process.
