Question 1

An unresponsive patient is found sitting in the front seat of a vehicle with his legs pinned under the dash.Once his legs have been freed,which of the following methods should be used for removal of the patient?

Accepted Answer

The rapid extrication technique is specifically designed for situations where a patient needs to be quickly removed from a vehicle, especially in cases where they might be in immediate danger or require urgent medical attention. This method is appropriate for an unresponsive patient with previously pinned legs, as it allows for a swift and safe removal from the vehicle to provide necessary medical care.

Question 2

Which of the following is an advantage of removing the roof of a vehicle that has sustained major damage in a collision?

Accepted Answer

Removing the roof of a vehicle that has sustained major damage in a collision can provide all three advantages listed - it makes the interior of the vehicle accessible, provides better access to patients for EMTs, and creates a large exit through which to remove patients.

Question 3

Which safety device prevents car doors from opening during a collision?

Accepted Answer

The Nader pin is a safety device designed to prevent car doors from opening during a collision, named after consumer advocate Ralph Nader.

Question 4

You are assessing a patient in the front seat of a vehicle that was involved in a head-on collision.As you examine the interior of the vehicle,you notice the air bags have not deployed.What action should you take in order to render the scene safe to work?

Accepted Answer

Disconnecting the battery and waiting 2 minutes before entering the vehicle is a safety measure to ensure that any residual electrical energy in the system is dissipated, reducing the risk of airbag deployment while the rescuer is inside the vehicle.

Question 5

When attempting to extinguish a fire inside the passenger compartment,it is important to:

Accepted Answer

Using the extinguishing agent sparingly is important to avoid creating a cloud of powder that can impair visibility and breathing. Overuse of the extinguishing agent may also spread the fire or cause damage to the vehicle and patients.

Question 6

You respond to the scene of a motor vehicle collision involving a small pickup truck that struck the rear of a moving tractor-trailer.The driver of the tractor-trailer is walking around and complains of neck pain.The driver of the pickup truck is conscious,but cannot exit the vehicle because the door is stuck and the steering wheel is displaced onto his lap.The passenger of the pickup truck is sitting upright in the passenger seat,is unconscious,but has radial pulses.Access to the passenger is not obstructed.A fourth patient,who was sitting in the pickup truck bed,is found about 10 feet away and responds to commands appropriately.Assuming your ambulance is the only emergency vehicle on the scene currently,which of the following patients should be packaged for transport first by the next arriving ambulance?

Accepted Answer

The passenger in the pickup truck's front seat is unconscious, but has radial pulses indicating adequate circulation. This patient should be packaged for transport first to a hospital because it is a potential airway and breathing emergency. The driver of the tractor-trailer is walking around and can wait for transport. The driver of the pickup truck cannot exit the vehicle and may need extrication, but their condition is stable. The passenger ejected from the pickup truck bed has responded to commands appropriately and is therefore considered a lower priority for transport compared to the unconscious passenger in the front seat.

Question 7

Which of the following is the rule of thumb for determining the stability of a vehicle that has been involved in a collision?

Accepted Answer

The rule of thumb for determining vehicle stability after a collision is that it should only be considered stable after assessment by trained rescue personnel. This is because there may be hidden damage or structural instability that could cause the vehicle to shift or tip over, even if it appears upright and stationary.

Question 8

Which of the following is a reason that the vehicle doors are removed to extricate the patient rather than pulling the patient through an open window?

Accepted Answer

Removing the doors allows for proper spinal immobilization, which is crucial in cases where a spinal injury is suspected. Pulling a patient through an open window can compromise spinal alignment and potentially worsen their condition. Avoiding criticism or being cut by glass are not valid reasons for choosing this method of extrication, and making the vehicle interior less accessible is not relevant to the patient's care.

Question 9

Which of the following is the EMT's key role at the scene of an auto extrication?

Accepted Answer

The EMT's key role at the scene of an auto extrication is to serve as a patient advocate, ensuring the patient's medical needs are prioritized during the extrication process.

Question 10

Which of the following methods should the EMT use first to attempt to access a patient in a vehicle while awaiting arrival of a rescue crew?

Accepted Answer

The EMT should first attempt to see if any of the vehicle's doors will open to gain access to the patient. This is the safest and most efficient method, as opposed to potentially causing damage to the vehicle or injuring the patient with broken glass. Only if all doors are locked and cannot be opened should the EMT consider alternative methods.

Question 11

Stabilizing a vehicle is unnecessary when a vehicle is on its roof with:

Accepted Answer

The answer of Stabilizing a vehicle is unnecessary when a...

Question 12

Once access to the patient is gained,which of the following is the next goal during an auto extrication?

Accepted Answer

Once access to the patient is gained, the next step is to perform a primary assessment and rapid trauma examination. This is important to determine the patient's condition and prioritize any necessary medical interventions. Disentanglement of the patient and extrication from the vehicle can occur concurrently with the primary assessment. Stabilization of the vehicle may be necessary during the extrication process, but it is not the immediate next goal.

Question 13

Upon arrival at the scene of a motor vehicle collision,you find a vehicle that is on fire.The fire is confined to the engine compartment and the hood is tightly closed.Of the following,which is the BEST course of action?

Accepted Answer

Opening the hood can increase the air supply and cause the fire to flare up, making the situation more dangerous. Wetting the interior of the vehicle or discharging a fire extinguisher onto the patient's clothing does not directly address the fire's containment or extinguishment. The priority in this scenario is to safely extricate the patient from the vehicle while ensuring the safety of rescuers and bystanders.

Question 14

You are managing a patient who is being extricated from a vehicle by a rescue crew using hydraulic tools.Which of the following items should you use in order to protect your patient during the extrication process?

Accepted Answer

The answer of You are managing a patient who is...

Question 15

When extrication will involve cutting the roof off a vehicle,stabilization of the vehicle should include:

Accepted Answer

The answer of When extrication will involve cutting the roof...

Question 16

Which of the following describes vehicle glass that is designed to break into small pieces rather than shattering into sharp fragments?

Accepted Answer

Tempered glass is designed to break into small, rounded pieces upon impact, rather than sharp fragments. This makes it safer for car windows and windshields, as the risk of severe injury from flying glass shards is reduced. Plexiglas is a type of plastic material, while leaded and alloy glass refer to different types of glass manufacturing processes and do not necessarily have the same safety properties as tempered glass.

Question 17

On arrival at a vehicle collision,you observe a small fire in the engine compartment.A bystander is attempting to smother the fire with a jacket as you approach with an A-B-C extinguisher from your ambulance.Which of the following is the BEST method of extinguishing the fire?

Accepted Answer

The best method of extinguishing the fire is to aim at the base of the fire and use short bursts until the fire is out. This will help to quickly extinguish the fire at its source and prevent it from spreading. Option A is not recommended as it may not effectively extinguish the fire and can waste the extinguishing agent. Option C is not recommended as closing the hood may trap the fire and cause it to spread. Option D is not recommended as it may push the fire towards the bystander or other parts of the vehicle, causing the fire to spread.
