Question 1

Which of the following human factors can lead to an increased risk of injury for an EMT at the scene of a vehicle collision?

Accepted Answer

All of the listed human factors could lead to an increased risk of injury for an EMT at the scene of a vehicle collision. Physical problems may impede an EMT's ability to effectively perform necessary tasks. A careless attitude toward personal safety can lead to reckless behaviors, increasing the likelihood of injury. Lack of proficiency in the use of rescue tools can also lead to mistakes or accidents that could result in injury.

Question 2

Which of the following is the BEST protection for an EMT's upper body during an extrication operation?

Accepted Answer

A firefighting turnout coat provides the best protection for an EMT's upper body during an extrication operation, as it is specifically designed to protect against heat, flames, and chemicals. Thick wool coats and nylon jackets with asbestos lining are not appropriate for this purpose, as they do not offer adequate protection against these hazards. A thick fireproof blanket draped around the shoulders may provide some level of protection, but it is not as effective as a turnout coat designed for this purpose.

Question 3

Which of the following can serve as appropriate eye protection for an EMT on the scene of an extrication?

Accepted Answer

Face conforming goggles would provide appropriate eye protection for an EMT on the scene of an extrication, as they would protect the eyes from debris and other hazards without obstructing vision. Prescription eyeglasses may provide some protection, but are not specifically designed to protect against debris or impact. Plastic face shields and shields of a firefighter's helmet may be too large or restrictive for an EMT's needs on an extrication scene.

Question 4

The safest way to extinguish a road flare is to:

Accepted Answer

It is safest to let a road flare burn out completely. Trying to extinguish it can result in accidental burns or even further ignition of flammable materials.

Question 5

Which of the following may be a source of ignition when an ambulance is parked off the roadway in a field of dried grass?

Accepted Answer

The catalytic converter can become extremely hot and potentially ignite dried grass or other flammable materials that come into contact with it.

Question 6

Which of the following is NOT an example of a specialty rescue team?

Accepted Answer

Advanced cardiac life support is not a specialty rescue team, but rather a medical intervention used by healthcare professionals to manage cardiac emergencies. Water rescue, confined space, and high angle rescue are all examples of specialty rescue teams that require specialized training and equipment to respond to specific types of emergencies.

Question 7

When working at a nighttime emergency on a roadway,which of the following safety considerations should the prudent EMS provider do to increase safety?

Accepted Answer

Operating amber warning lights only is the best choice as it allows the EMS provider to warn oncoming traffic of the emergency without potentially blinding drivers or causing confusion with other emergency response lighting. Keeping all lights on or using high beams can result in decreased visibility for drivers, while keeping only the fog lights on may not provide enough warning to oncoming traffic.

Question 8

Which of the following is the MOST common type of rescue across the United States?

Accepted Answer

Vehicle rescue is the most common type of rescue across the United States, primarily due to the high number of vehicles and traffic incidents occurring daily.

Question 9

When placing cribbing:

Accepted Answer

The answer of When placing cribbing:
...

Question 10

You are at the scene of a vehicle collision on an interstate highway.There are two cars involved and both are out of the lanes against the median wall.As an EMS provider,what is your primary safety concern?

Accepted Answer

The primary safety concern for an EMS provider at the scene of a vehicle collision on an interstate highway is watching for distracted drivers who are driving past the scene. This is because the EMS provider and other responders are at risk of being struck by passing vehicles, especially if the scene is not properly marked with flares or other warning devices. It is important to ensure that the scene is safe for all involved, including responders and bystanders, before proceeding with patient care. The other options presented are also important safety considerations, but not the primary concern in this scenario.

Question 11

When controlling the scene of an emergency involving damaged power poles and downed electrical wires,the EMT must remember to:

Accepted Answer

The EMT should request appropriate personnel, such as utility workers, to cut the power source to ensure safety, as they are trained and equipped to handle electrical hazards.

Question 12

Which of the following phases of extrication comes before the other three phrases?

Accepted Answer

Preparing for the rescue is the initial phase of extrication, where planning and gathering necessary equipment and personnel occurs before assessing the situation or managing hazards.

Question 13

The largest single hazard associated with EMS highway operations is:

Accepted Answer

The largest single hazard associated with EMS highway operations is traffic flow. EMS providers are often required to work in the middle of busy highways where they are at risk of being struck by passing vehicles. Therefore, it is crucial for emergency responders to take appropriate measures to ensure their own safety while operating on the highway.

Question 14

Which of the following is a common reason that EMTs are struck by motor vehicles at the scene of motor vehicle collisions on roadways?

Accepted Answer

Drivers often get distracted by the scene of a collision and fail to pay attention to their surroundings, including the presence of EMTs. This can put EMTs at risk of being struck by a motor vehicle. The other options (B and C) are not common reasons for EMTs being struck by motor vehicles.

Question 15

Which of the following is NOT a phase of the extrication process?

Accepted Answer

The extrication process typically includes four phases: gaining access to the patient, disentanglement, extrication, and termination/rescue of the patient. Simplification is not a recognized phase of this process.

Question 16

Which of the following is a common hazard associated with the inner circle of a typical auto extrication?

Accepted Answer

The answer of Which of the following is a common...

Question 17

While performing night operations,which of the following combinations of lights provide maximum visibility?

Accepted Answer

The answer of While performing night operations,which of the following...

Question 18

When responding to an emergency located on an interstate highway in a medium-duty ambulance,the vehicle should be positioned:

Accepted Answer

Positioning the ambulance in the same direction as other response vehicles in a single line ensures a coordinated and organized response, minimizing disruption to traffic and enhancing safety for both responders and other road users.

Question 19

You have arrived at the scene of a vehicle collision in which there are utility wires down around the vehicle.The three occupants appear dazed and other responding units have not yet arrived.Which of the following is the BEST course of action?

Accepted Answer

The best course of action is to stay back and caution the occupants to stay inside the vehicle until utility company personnel arrive to secure the downed wires. The wires may be energized and can cause electrocution if touched. Encouraging the occupants to exit the vehicle by jumping free of the vehicle before touching the ground may also result in electrocution. Cooling the wires with large amounts of water is also not recommended as it may conduct electricity and cause electrocution. Pushing the wires out of the way with a long pry-bar is also not recommended as it may cause the wires to shift and may result in electrocution.

Question 20

Which of the following considerations should be determined when conducting a scene size-up at night of a single vehicle collision involving a rollover?

Accepted Answer

The mechanism of injury is important to determine in any collision, and especially in a rollover, as it can provide valuable information about the types and severity of injuries the patient may have sustained. The make and model of the vehicle, number of supervisors needed, and determining which patient is the least injured are not priorities in the initial scene size-up.
