Question 1

Which of the following is the highest priority during extrication?

Accepted Answer

Ensuring your personal safety is always the highest priority during extrication to prevent adding yourself as another victim, following the principle of "scene safety" in emergency response protocols.

Question 2

Which of the following should be used to protect a patient during extrication?

Accepted Answer

Goggles are used to protect a patient's eyes from debris and other hazards during extrication.

Question 3

Under which of the following conditions are safety vests with reflective trim effective in increasing the visibility of the EMT?

Accepted Answer

Safety vests with reflective trim are effective in increasing the visibility of the EMT on sunny days, cloudy days, and at night. The reflective trim can reflect light back to its source, making the EMT more visible in low light conditions.

Question 4

You are at the scene of a motor vehicle collision in which a single vehicle has collided with a tree.You note that the driver's side air bag has deployed.Which of the following is recommended by air bag manufacturers?

Accepted Answer

According to air bag manufacturers, it is recommended to lift the air bag and inspect the steering wheel for damage. Cutting away the fabric portion of the air bag can be dangerous and can cause the airbag to deflate unpredictably. Using a portable fan to ventilate the car is not necessary as the powder from the airbag will settle quickly. Sharply striking the front bumper is not recommended as it can cause further damage to the vehicle and potentially harm the individuals involved in the collision. It is important to prioritize safety and follow the recommendations provided by the manufacturers.

Question 5

Which of the following BEST describes why it is important for the EMT to understand the extrication process?

Accepted Answer

As the EMT on scene, it is important to anticipate any potential dangers during the extrication process in order to ensure the safety of the patient and all personnel involved. Anticipating these dangers can help the EMT make informed decisions and take appropriate action as necessary. Providing direction or taking over the extrication process should only be done if requested by the rescue technicians and with the understanding that the EMT may not have the same level of training and expertise as the technicians.

Question 6

Which of the following provides the BEST protection for the EMT's hands during a vehicle rescue operation?

Accepted Answer

Leather gloves offer the best protection for EMTs during vehicle rescue operations due to their durability and ability to protect against cuts, abrasions, and other injuries that can occur when working with metal, glass, and other materials found in vehicle wreckage.

Question 7

Which of the following is an important reason for controlling spectators at the scene of an extrication incident?

Accepted Answer

Controlling spectators at the scene of an extrication incident is important for several reasons. First, spectators may get injured if they are not kept at a safe distance from the incident. Secondly, it ensures respect for the patient's privacy by not allowing onlookers to witness the potentially traumatic event. Lastly, spectators may interfere with rescue efforts by getting in the way of responders or trying to assist in the rescue without proper training. Therefore, all of the above reasons are important for controlling spectators at the scene of an extrication incident.

Question 8

Which of the following is a good choice for preventing further injury to a patient during auto extrication?

Accepted Answer

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

Question 9

Which of the following should the EMT consider when protecting a patient during extrication?

Accepted Answer

All of the listed factors should be considered when protecting a patient during extrication. Noise can be damaging to a patient's hearing, weather can increase the risk of hypothermia or heat exhaustion, and debris can cause further injury if not cleared from the area.

Question 10

Which of the following is the first concern when you are caring for a patient who has been in a vehicle collision?

Accepted Answer

Your own safety is always the first concern when responding to any emergency situation, including a vehicle collision. This ensures that you can effectively assist others without becoming a victim yourself.

Question 11

You are on the scene of a vehicle collision involving a downed power line.You are walking in an area you feel is a safe distance from the line and begin to feel a tingling sensation in your feet.Which of the following would be a proper method of ensuring your safety while exiting the area?

Accepted Answer

Turning 180 degrees and shuffling away (keeping your feet close together and taking small steps) is the safest method for avoiding electric shock in this scenario. This will minimize the chances of your feet being at different voltages, which could create an electrical circuit through your body. Hopping or running could also create an electrical circuit through your body and increase the risk of shock.

Question 12

If you are first on scene,what should you do first in determining where and how should you park your apparatus?

Accepted Answer

Before parking the apparatus, it is important to establish command and confirm the exact location of the incident with the dispatch center. This will ensure that the apparatus is parked in the most strategic location for the situation at hand.

Question 13

You have arrived at the scene of a motor vehicle collision to find that there are several critically injured patients.Which of the following should you do first?

Accepted Answer

In a situation with multiple critically injured patients, the first step is to ensure there are enough resources on the scene to manage the situation effectively. Calling for additional rescue units and transporting ambulances ensures that there will be sufficient personnel and equipment to triage, treat, and transport all patients as needed.

Question 14

Which of the following phases of extrication follows the other three phases?

Accepted Answer

The phases of extrication should be followed in the following order: 1) recognizing and managing hazards, 2) stabilizing the vehicle, 3) gaining access to the patient, and 4) immobilizing and extricating the patient. Therefore, choice B (immobilizing and extricating the patient) follows the other three phases.

Question 15

When disconnecting a battery cable to disrupt a vehicle's electrical system,the EMT should disconnect the:

Accepted Answer

The EMT should disconnect the negative cable from the battery. This reduces the risk of electrical shock or damage to the vehicle's electrical system.

Question 16

If the steering wheel must be displaced during extrication and the air bag has not deployed,which of the following actions is recommended by air bag manufacturers?

Accepted Answer

Disconnecting the battery cables is recommended to help ensure the electrical system is deactivated, reducing the risk of accidental airbag deployment during extrication.

Question 17

Which of the following is adequate protection for the EMT's head while at the scene of an auto extrication?

Accepted Answer

A standard construction hardhat is appropriate protection for the EMT's head during an auto extrication. It provides impact protection from falling debris or objects and protection from head injuries due to blunt force trauma. Firefighting helmets are designed for protection from heat and flame, but may not provide sufficient impact protection. A watch cap and Nomex hood provide some insulation and prevent burns, but do not provide adequate head protection.

Question 18

Which of the following activities should NOT occur during the scene size-up?

Accepted Answer

Providing airway management should not occur during the scene size-up, as this should be done during the primary assessment. The scene size-up is focused on assessing the situation and determining the resources needed to provide care. B, C, and D are all appropriate activities during the scene size-up.

Question 19

Which of the following measures can the EMT take to create a safer extrication scene?

Accepted Answer

Setting up road flares every 10 feet for a safe distance to divert traffic away from the collision helps create a safer extrication scene by alerting oncoming traffic to the hazard and directing them away from the scene.

Question 20

Which of the following is an unsafe behavior that contributes to most injuries at the scene of vehicle collisions?

Accepted Answer

Not wearing proper protective gear is the most unsafe behavior that contributes to most injuries at the scene of vehicle collisions. This can include not wearing high visibility clothing, gloves, helmets, and other protective equipment.
