AAOS EMT Eleventh Edition Section 9: EMS Operations Actual Exam Newest With Complete
Questions And Correct Detailed Answers| Brand New Version!
Question 1
Which type of ambulance features a conventional, truck cab-chassis with a modular ambulance
body that can be transferred to a newer chassis as needed?
A) Type I
B) Type II
C) Type III
D) Type IV
E) Modular Van
Correct Answer: A) Type I
Rationale: A Type I ambulance is mounted on a truck chassis. A Type II is a standard van
with a forward-control integral cab body. A Type III is a specialty van with a modular body
that can also be transferred, but it is built on a van chassis rather than a truck chassis.
Question 2
How should medical equipment and supplies be stored in the patient compartment of an
ambulance?
A) By alphabetical order of the manufacturer.
B) By the size and weight of the items.
C) According to the urgency and frequency of their use.
D) In locked cabinets only to prevent theft.
E) Based on the preference of the senior paramedic.
Correct Answer: C) according to the urgency and frequency of their use.
Rationale: Items required for life-threatening conditions (airway management, bleeding
control) must be within easy reach of the primary patient care seat (usually the airway
seat) to ensure rapid access during emergencies.
Question 3
Which of the following is considered an example of "regional" equipment or supplies that may
vary by geographic location?
A) Sterile gauze pads
B) DuoDote Auto-Injector (Nerve Agent Antidote)
C) A standard blood pressure cuff
D) Rigid cervical collars
E) Portable oxygen cylinders
Correct Answer: B) DuoDote Auto-Injector
Rationale: Regional equipment is influenced by local terrain or specific local risks. For
example, areas near industrial plants may carry nerve agent kits, while mountain regions
may carry specialized cold-weather gear.

Question 4
In terms of accessibility and safety, where is the LEAST practical place to store a portable
oxygen cylinder?
A) In a jump kit
B) In a secure wall bracket in the patient compartment
C) Under the patient stretcher
D) In the driver's compartment
E) In an outside storage compartment
Correct Answer: D) in the driver's compartment.
Rationale: Storage in the driver's compartment makes the cylinder inaccessible during
patient care. Oxygen should be stored where the EMT providing care can reach it, or in a
secured external compartment if it is a large cylinder.
Question 5
Common safety equipment carried on an ambulance includes all of the following EXCEPT:
A) Fire extinguishers
B) Warning flares or triangles
C) Hazardous materials (HazMat) Level A encapsulated gear
D) Disposable gloves and eye protection
E) High-visibility safety vests
Correct Answer: C) hazardous materials gear.
Rationale: While EMTs carry Basic Life Support (BLS) and personal protective equipment,
fully encapsulated Level A HazMat gear requires specialized training and is carried by
technical HazMat teams, not standard ambulances.
Question 6
When a dispatcher receives an emergency request, they should routinely gather all of the
following information EXCEPT:
A) The caller's phone number
B) The exact location of the emergency
C) The nature of the call (e.g., chest pain, car crash)
D) The patient's detailed past medical history
E) The number of patients involved
Correct Answer: D) patient's medical history.
Rationale: Dispatchers must gather enough information to send the correct resources
(location, nature, number of patients). A detailed medical history is gathered by the EMT
on scene; gathering it during the call would delay the emergency response.
Question 7
What is the first priority for an EMT immediately upon arriving at the scene of a traumatic
injury?
, 3
A) Begin chest compressions
B) Notify dispatch of arrival and observe for safety hazards
C) Contact the patient's family
D) Check the patient's blood pressure
E) Move the patient into the ambulance immediately
Correct Answer: B) observe the scene for safety hazards.
Rationale: Scene size-up is the most critical first step. An EMT cannot help a patient if they
become a victim themselves due to traffic, downed power lines, or hazardous materials.
Question 8
You arrive at a crash involving a tractor-trailer that is emitting a green cloud. The conscious
driver is bleeding from the head. After calling for HazMat, where should you park?
A) Downwind of the rig to stay away from traffic.
B) Directly next to the driver's door to reach the patient faster.
C) Position the ambulance upwind and at a safe distance.
D) Downhill of the leaking rig.
E) Inside the green cloud so the driver can see you.
Correct Answer: C) position the ambulance upwind.
Rationale: If a chemical leak is suspected, the ambulance must be positioned upwind and
uphill. This prevents the crew from being exposed to potentially toxic vapors or runoff
while waiting for technical teams to secure the scene.
Question 9
During the "transport phase" of an ambulance call, what is the MOST important task for the
EMT in the back?
A) Completing all paperwork for the hospital.
B) Driving as fast as possible to save time.
C) Conversing with the patient and providing reassurance.
D) Calling the patient's insurance company.
E) Repacking the jump kit for the next call.
Correct Answer: C) converse with the patient and provide reassurance.
Rationale: During transport, the EMT's primary focus is on monitoring the patient,
reassessing vitals, and providing psychological support and reassurance to reduce the
patient's anxiety.
Question 10
You have just delivered a trauma patient and the ambulance is contaminated with blood and in
total disarray. Dispatch calls you for another emergency. You should:
A) Respond to the call and clean up later.
B) Advise dispatch you are out of service and to send another unit.
C) Tell dispatch you will be there in 30 seconds.
, 4
D) Have your partner clean while you drive to the next scene.
E) Clean only the equipment you think you will need.
Correct Answer: B) advise the dispatcher that you are out of service and to send another
unit.
Rationale: An ambulance is not ready for service if it is contaminated or missing essential
supplies. Returning to service before cleaning/restocking endangers the next patient and
the crew.
Question 11
What is the definition of "cleaning" in the context of ambulance maintenance?
A) Using heat to kill all microorganisms.
B) Using a high-level chemical to destroy spores.
C) The process of removing dirt, dust, blood, or visible contaminants.
D) Soaking equipment in bleach for 24 hours.
E) Painting the equipment to make it look new.
Correct Answer: C) cleaning.
Rationale: Cleaning is the basic removal of visible debris. Disinfection and sterilization are
higher levels of decontamination that involve killing pathogens.
Question 12
General guidelines for safe ambulance driving include all of the following EXCEPT:
A) Anticipating the actions of other drivers.
B) Driving with a "cushion of safety."
C) Regularly using the siren as much as possible to clear traffic.
D) Stopping at all red lights and stop signs.
E) Driving defensively.
Correct Answer: C) regularly using the siren as much as possible.
Rationale: Sirens can be distracting to the driver and can cause other motorists to panic and
behave unpredictably. They should only be used when necessary and with great caution.
Question 13
What does maintaining a "cushion of safety" mean when operating an ambulance?
A) Keeping your air bags turned on.
B) Keeping a safe distance in front of you and being aware of blind spots.
C) Driving in the shoulder of the highway.
D) Always driving with a police escort.
E) Padding the dashboard of the ambulance.
Correct Answer: B) keeping a safe distance between your ambulance and the vehicles in
front of you and remaining aware of vehicles potentially hiding in your mirrors' blind
spots.
Rationale: A cushion of safety allows for reaction time. Because ambulances are heavier and
