23 EMS Operations Practice Questions & Answers
Every EMS Operations practice question from the EMT (NREMT) Practice Test, with the correct answer and a short explanation.
Start practice test →1. During an adult mass-casualty incident you begin START triage. The first patient is breathing 34 times per minute and has a radial pulse. Using START, how should you tag this patient?
- A.BLACK / Deceased
- B.GREEN / Ambulatory
- C.RED / Immediate✓ Answer
- D.YELLOW / Delayed
In START, a respiratory rate greater than 30 per minute is an automatic Immediate (RED) tag because it signals inadequate oxygenation and ventilation; you stop and tag without checking perfusion or mental status.

2. A patient in an MCI is breathing 24 times per minute, but you cannot feel a radial pulse and capillary refill is 3 seconds. Under START, this patient is:
- A.GREEN / Ambulatory
- B.RED / Immediate✓ Answer
- C.BLACK / Deceased
- D.YELLOW / Delayed
Respirations are under 30, so you assess perfusion next; an absent radial pulse (or capillary refill greater than 2 seconds) indicates poor perfusion and requires an Immediate (RED) tag.

3. During START triage, a patient is breathing 20 times per minute and has a radial pulse, but cannot follow the simple command to squeeze your hand. This patient should be tagged:
- A.YELLOW / Delayed
- B.GREEN / Ambulatory
- C.BLACK / Deceased
- D.RED / Immediate✓ Answer
With adequate respirations and perfusion, the final START check is mental status; a patient who cannot follow simple commands is tagged Immediate (RED) because altered mentation may indicate hypoxia or serious head injury.

4. Using JumpSTART on a young child in an MCI, you find the child is not breathing but you can palpate a pulse. Your next action is to:
- A.Open the airway and give 5 rescue breaths✓ Answer
- B.Start chest compressions and ventilations
- C.Tag RED and move on without giving breaths
- D.Tag BLACK because the child is apneic
JumpSTART recognizes that pediatric arrests are usually respiratory in origin, so an apneic child WITH a pulse gets 5 rescue breaths; if breathing resumes, tag RED, and if it does not, tag BLACK.

5. While performing START primary triage in an MCI, which interventions are you permitted to perform on patients as you sort them?
- A.Opening the airway and stopping major bleeding✓ Answer
- B.Splinting fractures and bandaging open wounds
- C.Full BLS treatment before moving to the next
- D.A complete set of vital signs on each patient
During primary triage the goal is rapid sorting, so interventions are limited to opening the airway (repositioning) and controlling major hemorrhage; definitive treatment waits until triage is complete—triage precedes treatment.

6. You arrive first at a multi-vehicle crash with at least six injured people. Before providing patient care, your priority action is to:
- A.Load and transport the closest patient at once
- B.Establish command and call for more resources✓ Answer
- C.Treat the most seriously injured patient first
- D.Wait for a supervisor before doing anything
The first-arriving unit must establish command, perform a scene size-up, and request resources early—not begin treating one patient—because committing to a single patient (freelancing) leaves the incident unmanaged and resources unrequested.

7. You find an unconscious adult who was struck by a car. There is no family or guardian present. Under what type of consent may you treat him?
- A.Involuntary consent
- B.Expressed consent
- C.Implied consent✓ Answer
- D.Informed consent
Implied consent is the legal presumption that an unresponsive or otherwise incompetent patient would consent to the lifesaving care a reasonable person would want under the circumstances.

8. Which patient may legally refuse emergency medical care?
- A.An alert, oriented adult who knows the risks✓ Answer
- B.An adult knocked unconscious by a head injury
- C.A 15-year-old with a minor laceration, alone
- D.A visibly intoxicated adult who is confused
Only a competent adult who is alert, oriented, and able to understand the risks and consequences of refusal may legally decline care; intoxication, altered mentation, and minor status all invalidate a refusal.

9. A patient later sues, claiming an EMT harmed them. Which of the following is NOT one of the four elements of negligence?
- A.Damages and proximate causation
- B.Malicious intent to harm the patient✓ Answer
- C.The provider's legal duty to act
- D.A breach of the standard of care
The four elements of negligence are duty to act, breach of that duty (standard of care), damages/harm, and proximate causation linking the breach to the harm; malicious intent is not required—negligence is about a failure to meet the standard, not intent.

10. An EMT begins caring for a patient, then leaves the scene before another provider of equal or higher training takes over. This is best described as:
- A.Battery
- B.False imprisonment
- C.Assault
- D.Abandonment✓ Answer
Abandonment is terminating care of a patient without ensuring that care is transferred to a provider of equal or higher training once a duty to act has been established.

11. You respond to a patient in respiratory distress who has a valid, signed DNR order. The DNR means you should:
- A.Begin CPR at once despite the order
- B.Withhold all care and only monitor him
- C.Refuse to transport the patient at all
- D.Provide comfort and supportive care✓ Answer
A valid DNR directs only that resuscitation (CPR) be withheld in cardiac/respiratory arrest; it does not withhold care, so you must still provide comfort and supportive measures such as oxygen, positioning, and suctioning.
Source: Advance directive / DNR standard — withholds resuscitation only; comfort care continuesReport a problem with this question
12. Under HIPAA, in which situation may you share a patient's protected health information (PHI) without specific written authorization?
- A.Telling a curious off-duty coworker about the call
- B.Posting details on social media with no name
- C.Giving a verbal report to the receiving hospital✓ Answer
- D.Describing the patient to a friend who asks
HIPAA permits disclosure of PHI for treatment, payment, and health-care operations (or when legally required); handing off to the receiving hospital is a treatment disclosure, whereas the other options are unauthorized breaches even without a name.

13. You arrive at an overturned tanker leaking an unknown liquid and displaying a placard. As an EMT trained to the awareness level, you should:
- A.Isolate the area, deny entry, and call for HazMat✓ Answer
- B.Enter at once to rescue any trapped victims
- C.Drive downhill and downwind for a closer look
- D.Decontaminate patients inside the hot zone
EMTs are trained to the awareness level: recognize the hazard, isolate the scene, deny entry, and summon specialized HazMat resources—they do not enter the contaminated zone or attempt rescue/decon without proper training and PPE.

14. When staging near a hazardous-materials release, how should you position yourself and your ambulance?
- A.Uphill and upwind of the leak, in the cold zone✓ Answer
- B.Downhill and downwind for a faster approach
- C.As close to the leak as possible to observe it
- D.Within the warm decontamination corridor
You approach and stage uphill and upwind to avoid drifting vapors and liquid runoff, keeping the command post, staging, and patient treatment in the cold (safe) zone.

15. In the Incident Command System, which of the following is a Command Staff position rather than a General Staff section?
- A.Operations Section
- B.Planning Section
- C.Logistics Section
- D.Safety Officer✓ Answer
The Command Staff consists of the Safety Officer, Public Information Officer, and Liaison Officer, who report directly to the Incident Commander; Operations, Planning, Logistics, and Finance/Administration are the General Staff sections.

16. In ICS, what is the recommended span of control—the number of subordinates one supervisor should manage?
- A.1 to 2 subordinates
- B.Unlimited, as needed
- C.3 to 7 subordinates✓ Answer
- D.8 to 12 subordinates
Effective span of control in ICS is 3 to 7 subordinates per supervisor, with 5 being optimal; exceeding this range degrades supervision, so command is subdivided to keep spans manageable.

17. A medical helicopter has landed and the pilot signals you to approach. How should you approach the aircraft?
- A.From the uphill side when on a slope
- B.From any direction while staying crouched
- C.From the front, within the pilot's view✓ Answer
- D.From the rear, passing the tail rotor
Always approach a helicopter from the front within the pilot's line of sight and only after being signaled; the spinning tail rotor is nearly invisible and deadly, so you must never approach from the rear, and on a slope you approach from the downhill side.

18. You are driving to a call with lights and siren activated and approach a red traffic light at an intersection. What is required of you?
- A.Stop, and then proceed with due regard when clear✓ Answer
- B.Proceed through the red light without slowing
- C.Emergency status exempts you from traffic laws
- D.The siren legally grants you the right of way
Lights and siren only request the right of way; under the due-regard standard the operator remains legally responsible for everyone's safety, so you must stop at a red light and proceed cautiously only when clear—most ambulance collisions occur at intersections.

19. You and a partner must lift a heavy stretcher. Which technique best protects you from injury?
- A.Hold the weight out away from the body
- B.Twist toward the cot while lifting it
- C.Keep the back straight and use the legs✓ Answer
- D.Bend at the waist and lift with the back
The power lift keeps the back straight and locked while using the stronger leg muscles, with the weight held close to the body and no twisting, which minimizes spinal strain and injury.
Source: EMS body mechanics — power lift: straight back, lift with legs, load close, no twistingReport a problem with this question
20. In which situation is an emergency move (such as a clothes drag) justified before completing a full assessment and spinal precautions?
- A.When the stretcher is parked too far away
- B.For every trauma patient, to save time
- C.Only when there is an immediate danger✓ Answer
- D.Whenever the patient asks to be moved
An emergency move is used only when an immediate danger (fire, explosion, hazardous materials, or the need to reach a critical patient) outweighs the risk of moving without full spinal precautions; you drag along the long axis of the body to protect the spine.

21. You receive a medication order by radio from online medical control. Before administering the medication, you should:
- A.Use the patient's full name on the air
- B.Carry out the order without confirming it
- C.Repeat the order back to medical control✓ Answer
- D.Give your own diagnosis over the radio
You echo (repeat back) orders received from medical control so the physician can confirm the order was received accurately before you act, which reduces medication and dosing errors.

22. After completing your patient care report (PCR), you notice you wrote the wrong blood pressure. How should you correct this error on the legal document?
- A.Throw out the report and start a new one
- B.Draw a single line through it, initial it✓ Answer
- C.Erase it and write in the correct value
- D.Cover it with correction fluid and rewrite
Because the PCR is a legal document, errors are corrected by drawing a single line through the mistake (leaving it legible), writing the correction, and adding your initials and the date; erasing or obliterating an entry suggests falsification.
Source: PCR documentation standard — single line through error, correction, initial and date; never eraseReport a problem with this question
23. According to the standard sequence of scene size-up, what is the FIRST step you take upon arriving at any scene?
- A.Take BSI precautions and put on PPE✓ Answer
- B.Determine the total number of patients
- C.Identify the mechanism of injury
- D.Request more units and resources
Scene size-up begins with taking standard/BSI precautions and donning PPE, because provider safety comes first; you then assess scene safety, the mechanism or nature of illness, the number of patients, and the need for additional resources.
