Get All Weeks Trauma Emergencies and Care Coursera Quiz Answers
Welcome to Trauma Emergencies and Care. In this course, you will learn about some of the mechanics and physics of trauma on the human body, and how this can cause injury. You will continue to expand your new vocabulary with medical terminology, and learn how to describe the different injuries you may see. You will also learn about the trauma system itself- and when it is important to transport patients to a trauma center.
Then we will dive into specific injuries based on what part of the body may be injured- or trauma by the system. There are different considerations in the trauma patients depending on both how, and where, they are injured.
And of course- you will learn your standard approach to a history and physical exam of the trauma patient. Finally, you will learn about something that you hope to never encounter: mass casualty incidents, or MCIs. These are occurrences where you may have multiple patients, and there is an organized and specific approach as a provider in these circumstances.

Quiz 02 : Introduction and Kinetics of Trauma Assessment
Q1. You are dispatched to a call of bicycle hit by a car. It’s a warm, busy, weekend day and the call occurs downtown.
- As you are driving to the call and thinking about your approach what is your first priority?
- 10 minute scene time: think about rapid scene and patient evaluation
- Spinal immobilization: Don’t miss a cervical spine injury
- Scene safety: Think about how you will control your scene with traffic and people passing by
- The golden period for trauma: if you have a sick trauma patient get them to the trauma center quickly
You arrive on scene and find the above situation. The patient is found just to the right of the bicycle and car. She is helmeted and lying still in the street. Per bystanders the bicyclist was riding straight and the car turned into her resulting a head-on type collision.
When considering the kinetic energy in the car compared to the bicycle and bicyclist, which of the following are true?
- This is an example of penetrating trauma
- If the car and the bike are going the same speed, the mass of the car will result in the car having greater kinetic energy
- The object in motion will stay in motion
- If the car was stopped and it’s velocity was zero prior to the accident it would still have a high kinetic energy
Q3. Look at the picture of your scene and what you know about the accident so far. What are your considerations based on this visual information? Choose all that apply
- An auto vs. bike is going to be high risk for serious injuries
- The likely mechanism of injury for this patient is blunt trauma
- There is not evidence of damage to the hood or windshield so impacts for bicyclist must be minimal
- There is only one impact associated with this crash and that is the patient/bike with the vehicle
Q4. All of the following are part of your responsibility when formulating your initial scene assessment (Choose all that apply):
- Letting the police call for any additional medical resources that are needed
- Identifying all patients involved
- Controlling traffic around the scene
- Evaluating the scene and formulating suspected mechanism of injury
Q5. In this call, the driver of the car declines needing medical care or evaluation. There was only one rider on the bike. She is lying on the street and as you approach you note you have not yet seen her move.
As part of your initial priorities to stabilize this patient. What would be the first thing to address?
- Airway compromise
- C spine immobilization
- Rapid transport to a trauma center
- Active, significant hemorrhage
Q6. When you approach the patient once the scene is safe, you knee down by her and ask her name. She opens her eyes and says something about “going to lunch”. She doesn’t know what year it is but can talk to you. She has a radial pulse that is around 120. You do not see any active external bleeding.
What is your initial assessment and plan for this patient based on the above information?
- Concerning for airway compromise. Prioritize ABC’s
- Potentially sick trauma patient- gather more information at the scene
- Stable trauma patient- complete your assessment on scene
- Unstable trauma patient- complete a rapid trauma assessment, expedite transport
Q7. By now you should have already known what ABC stands for. In this course we have added D and E. What do D and E stands for
- Decontaminate and Disability but E stands for Evacuation6 or Evacuation and Evaluation. 7
Q8. You have identified your patient as a sick trauma patient and now want to make sure you maximize your patient’s outcomes and you are part of the team responsible for patient ongoing care and transport.
Which of the following are priorities while caring for this patient?
- Appropriate, early c spine immobilization based on mechanism and altered mental status
- Short scene time and rapid transport are very important
- Prevent hypothermia
- Perform a systematic secondary survey
Q9. You run a call on a patient who is 28 years old and fell 20 feet from a ladder and landed in some bushes mostly on his feet. The patient is alert, has a glascow coma score (GCS) of 15, has normal vital signs, and has pain isolated to his ankles and low back. He is moving all his extremities and doesn’t have evidence of trauma. Based on the 2011 trauma triage criteria set out by the Centers for Disease Control (CDC)
- This patient must go to the highest level trauma center in the area
- This patient does not meet any of the criteria in step one or two for needing a trauma center
- Based on mechanism, this patient should go to a trauma center. This patient might not need to go to a level one trauma center
- There are not any concerning features to this patient presentation and the patient can be transported anywhere
Q10. There is an explosion at a local factory and you are dispatched there as one of the many responding units. The patient you end up taking care of has a piece of metal in his left leg right in the middle of the thigh. He also is having a hard time hearing your questions because he says his hearing went bad at the time of the blast as well. Based on the three phases of blast injuries, the patient’s penetrating trauma to his leg is considered part of the __________ phase of blast injury while the suspected injury to his tympanic membrane is considered part of the _________ phase.
Please answer the fill in the blanks using this format: __________ , ___________

Q5. All of your patients have been triaged and transported. The chaos is over, and so is your shift. You go back to the garage and change into your regular clothes. You feel exhausted and emotional.
True or false- it is important to discuss the events of the day with someone, be it a therapist, a friend, or coworker to help decompress and process what you all went through.
Q6. You have a patient that you are transporting to a trauma center who has a gunshot wound to the abdomen. The patient has a heart rate of 120, a respiratory rate of 28, a systolic blood pressure of 130 and their skin is pale, cool, and clammy.

- Class III and 30-40%
- Class I and <15%
- Class IV and >40%

He was able to get out of his own car, and walk over to your ambulance when you pull up on scene. He is complaining of abdominal pain. You sit him on the cot, and your partner gets vital signs while you start your assessment. Your partner tells you his vitals, which are: Heart rate 110, BP 86/44, respiratory rate 26. What are some indications that your patient may have internal bleeding? Choose all that apply
- His elevated heart rate
- His mechanism of injury

What physiologic response is the body doing if this is hemorrhagic shock that would account for his skin exam?
- Nothing, this is decompensated shock and the body is not responding
- Shunting blood away from the distal aspects of the body to ensure perfusion of the vital organs
- Releasing more neurochemicals to signal the brain to shut down
- Activating the fight or flight response to dilate blood vessels to the more distal parts of the body
