Question 1

Which of the following is NOT determined in a scene size-up?
A) Chief complaint
B) Mechanism of injury
C) Potential hazards to the EMS crew
D) Need for additional resources

Accepted Answer

Chief complaint is typically gathered during the patient assessment phase, not during the scene size-up. The other options are all important factors to consider during the scene size-up.

Question 2

You and your partner respond to a residence for a fall.You arrive to find a group of approximately 30 adults surrounding a middle-aged man who appears to be unconscious.A police car pulls in behind you.You should:
A) wait for the police officer to assess the safety of the scene.
B) enter the scene ahead of the police officer to provide care.
C) leave the area and stage until the scene is cleared of people.
D) have the police officer drag the victim over to the ambulance.

Accepted Answer

The presence of a large, potentially hostile crowd can make a scene unsafe for responders. It is important to wait for the police officer to assess the safety of the scene before entering. They can provide crowd control and ensure the safety of everyone on scene, including the patient and responders. Once the scene is deemed safe, medical treatment can begin. Option B is not recommended as it could put responders in danger, and option C is not always necessary if the crowd can be safely controlled. Option D is not appropriate as it is not within the police officer's role to move or transport patients.

Question 3

When considering the potential for injury from a fall,which of the following is LEAST important?
A) Height of the fall
B) Type of surface onto which the patient fell
C) Whether the patient struck anything with his body on the way down
D) Patient's weight

Accepted Answer

The patient's weight is not directly related to the potential for injury from a fall. However, it may affect the severity of the injury once a fall has occurred. Therefore, it is the least important factor to consider when assessing the potential for injury from a fall. Height of the fall, type of surface onto which the patient fell, and whether the patient struck anything with his body on the way down are all important factors that can determine the risk and severity of injury in a fall.

Question 4

Which of the following is NOT a consideration that should be used by the EMT in establishing the size of the danger zone?
A) Presence of hazardous materials
B) Wind direction
C) Amount of equipment needed
D) Fire

Accepted Answer

The amount of equipment needed is not a consideration in establishing the size of the danger zone. The EMT should consider factors such as the presence of hazardous materials, wind direction, and fire when determining the appropriate size of the danger zone.

Question 5

As you approach the scene of a motorcycle accident,you see an EMR trying to stop the bleeding on the patient's left arm.You notice that the EMR has blood covering the front of his shirt and running down his arms.What Standard Precautions are needed?
A) There is no need for Standard Precautions because you have no open injuries.
B) Gloves, gown, and face mask with eye shield are needed.
C) Gloves, gown, eye protection, and an N-95 or HEPA respirator are needed.
D) Gloves and gown only are needed.

Accepted Answer

Standard Precautions are necessary in any situation where bodily fluids are present, regardless of the type of injury. In this case, the EMR has blood on his clothing and skin, which could contain infectious pathogens. Gloves, gown, and face mask with eye shield will provide protection against contact with blood or other bodily fluids. Option C is not necessary unless there is a risk of airborne transmission, which is not indicated in this scenario. Option A is incorrect because Standard Precautions always apply when there is potential exposure to bodily fluids. Option D is insufficient since eye protection is also necessary.

Question 6

Which of the following situations requires additional action by the EMT during scene size-up?
A) A vehicle collision involving a tractor-trailer that appears to be empty.
B) The sound of a barking and growling dog upon approaching the door to a residence.
C) A bystander who is smoking a cigarette at the scene of an assault at a local park.
D) A news media helicopter arrives and hovers overhead at the scene of a vehicle collision.

Accepted Answer

The presence of a barking and growling dog indicates a potential safety hazard that needs to be addressed to ensure the safety of the EMTs and others on the scene.

Question 7

As you arrive at the scene of a house fire,a very upset man screams at you to help his young son,who is trapped under a piece of burning wood on the ground.Which of the following should you do first?

B) Size-up the scene before acting.
C) Perform an initial assessment on the patient.
D) Use a blanket to put out the fire on the piece of wood.

Accepted Answer

It is always important to size-up the scene before acting, especially during an emergency situation. Assessing the situation can help determine any potential hazards or dangers and allow for a safe and effective rescue. Once the scene is assessed, proper action can be taken to help the young boy trapped under the burning wood.

Question 8

Which of the following is true concerning the potential for violence at the scene of an EMS call?
A) An unusual lack of activity at the scene may signal impending violence against the EMT.
B) The chance for violence is very low at emergency scenes.
C) You do not need to worry about violence at an emergency scene once the police have secured it.
D) Signs of impending violence are obvious if you know what to look for.

Accepted Answer

An unusual lack of activity at an EMS scene may signal impending violence, as it could indicate that the perpetrator is waiting or planning an attack. EMTs should be aware of this possibility and take precautions to protect themselves. The chances for violence at an emergency scene are unpredictable and can vary depending on the situation. Police securing the scene does not guarantee safety, and signs of impending violence may not always be obvious.

Question 9

You are called to a motor vehicle collision where the car is on fire.You should ensure safety by:
A) borrowing turnout gear from the fire department.
B) remaining a safe distance from the car until the fire is out.
C) putting your unit back in service and leaving the scene.
D) using your fire extinguisher to put out the fire.

Accepted Answer

The safest action in this situation is to remain a safe distance away from the car until the fire department arrives and extinguishes the fire. Attempting to use a fire extinguisher or borrowing turnout gear without proper training and equipment could result in serious injury or death. Leaving the scene without ensuring the safety of anyone involved would be a violation of duty.
