Week 01: Medical Emergencies: CPR, Toxicology, and Wilderness Quiz Answers
Quiz : Cardiac Arrest and Shock Assessment
Q1. You are dispatched to a restaurant for a 28 yo female with trouble breathing. You arrive on scene and find a very worked up employee followed by a family member who is equally distraught. Both of them are urging you to hurry and get to the patient. She is in distress.
Given the above information what is your first priority?
- Perform your ABC’s
- Establish level of alertness using AVPU
- Be sure to bring your AED incase this is an arrest
- Establish the scene is safe
Q2. Your scene is safe and given the concern for a sick patient, you bring all of your equipment to evaluate the patient. You come across a patient that is sitting in a tripod position and appears in distress. Her eyes are open and she appears very anxious. She is able to answer your questions with one word answers, she is breathing about 40 times a minute and she has a weak radial pulse that you feel while you are beginning your assessment.
The patient’s airway and breathing are in tact although have very concerning features. A weak radial pulse in a patient with other signs of distress make you think this patient might have signs of shock. Which of the following are 3 of the 4 main categories of shock that you learned?
- Distributive, anaphylactic, neurogenic
- Cardiogenic, distributive, obstructive
- Hypovolemic, cardiogenic, distributive
- Neurogenic, septic, hemorrhagic
Q3. Because you are worried the patient is in shock, you lay the patient down on the floor and ask your partner to check a full set of vitals while you try to gather some more information. You call for advanced resources, strat to get the patient placed on a nonrebreather mask and the friend of the patient tells you while you are working that the patient is otherwise healthy. They were eating lunch and the symptoms started with her feeling a little short of breath and complaining of a scratchy voice. As you are placing the nonrebreather and doing a primary survey, the patient looks like this:
The eyes are swollen and there is a rash to the skin diffusely that the patient nods to say is itchy. Your partner reports the blood pressure is 84/50, the pulse is 130, the respiratory rate is still 40.
What do you think is the most likely cause of this patient’s shock?
- Pulmonary embolism
- Spinal cord problem
Q4. What are other symptoms that would suggest this patient’s symptoms are related to anaphylaxis? Choose all that apply
- Swelling to the back of the throat
- History of fever
- Recent trauma

- Check for a pulse, start CPR, apply AED pads, administer oxygen
- Administer oxygen, apply pads, start CPR, turn on the AED
- Start CPR, apply AED pads, turn on the monitor, check for a pulse
- Start CPR, gather more information from bystanders, apply oxygen, apply AED
Q7. Compression rate should be in a range of _______________ compressions per minute and depth of compression should be in a range of 2- 2.5 inches
Answer using range format (e.g., ___ to ___ ,or ___ – ___)
Q8. Where should AED pads should be placed? Choose all that apply
- On the stomach and the back
- On the left lateral chest wall and the back
- On the right anterior chest wall and left lateral chest wall

Q9. In contrast to many other types of medical emergencies, you will usually stay and work this cardiac arrests on scene rather than prioritizing rapid transport. What is the main reason for that?
- It’s easier to provide oxygenation and ventilations for patient on scene rather than while moving
- High quality chest compressions are difficult/impossible to provide while moving a patient
- ALS response will provide epinephrine faster than if you transported them to the hospital
- IV access is the most important thing in cardiac arrest care
Q10. Which of the following are good ways to maximize effectiveness of chest compressions? Choose all that apply
- Coordinate changing the person doing compressions with rhythm analysis
- Check for a pulse for at least 10-15 seconds
- Continue doing compressions while placing the AED pads

Week 03: Medical Emergencies: CPR, Toxicology, and Wilderness Quiz Answers
Quiz : Not All Who Wander Are Tox Assessment
Q1. Not all medical emergencies happen when you expect them to. Sometimes you are in uniform and dispatched there. Sometimes, because of your training, you will find yourself in a position to provide care outside the boundaries of usual work.
The alpine lake above sits at about 12,000 feet (3600 meters). You are on a backpacking trip with your friend near here. You are an experienced outdoors person and you have discovered that your friend is not as prepared for this adventure as you are. The weather this day started out comfortable around 65 degrees Fahrenheit (18 deg C) when you started hiking.
As you hike your body creates heat, you get warm and you start to sweat. Sweat evaporates off the body and carries heat away from us. This is an example of ___________
Q2. After hiking for 2 hours you decide to stop at the above lake. You decide to go for a walk around the lake while your friend starts to set up camp. You return from your short hike to find your friend had fallen in the lake while you were gone. He reports he is starting to get cold.
What will be the most reliable sign he has transitioned from mild to moderate hypothermia?
- He becomes confused
- He starts laughing for no reason
- He stops shivering
- His lips turn blue
Q3. You take over setting up camp and shortly thereafter you find him sitting next to his pack, staring off into space and doesn’t pay attention when you say his name. You rely on your EMT skills and assess his mental status. With AVPU and quickly realize your friend is alert but confused (he can’t describe why he is out hiking). Which of the following things could be causing his altered mental status in this scenario? Choose all that apply
- High altitude cerebral edema
- Heat stroke
Q4. You decide your friend is now a patient for you and kick into an initial evaluation. You quickly survey the area for safety or other clues that something happened while you were out on your walk around the lake. There is not anywhere he could have fallen, the scene is safe for you and your friend currently. Further primary evaluation is as follows:
Patient is able to speak, chest rise is symmetric bilaterally and he doesn’t look to be in any respiratory distress. His pulse is present and you notice it to be slow. His skin feels cool/cold. He is uncoordinated with basic movements. He is currently in his dry shirt but his shorts and shoes are wet from jumping in the lake.
You have decided his symptoms are related to being cold. It could be related to the altitude but that is less likely since he didn’t have any symptoms of altitude illness while you were hiking to the lake. What are your first 2 priorities for initial management?
- Rewarm the patient
- Descend from the elevation you currently are
- Prevent further heat loss
- Place an NPA (that you happened to bring in your bag for emergencies)
Q5You help your friend remove his wet clothing and put on the dry pants and extra pair of wool socks that you brought. You also give him your extra jacket. Other examples of active rewarming include (not limited to just the wilderness setting)? Choose all that apply
- Turning up the heat in the ambulance
- Heating some water for him to drink
- Making the patient start hiking out to help warm up
- Massaging his cold feet
On a different day and other adventure, you are on a search and rescue team that is dispatched to this very busy high mountain pass in the Colorado Rocky Mountains. You are told that there are multiple people down up on the pass. There was recently a thunderstorm that came through. Your time to get to the scene is relatively short (minutes) since you were stationed right near by.
The suspicion while you are making your way to the scene is that these patients are victims of lightning strike from the thunderstorm.
What is your priority when approaching the scene?
- The patients who are unresponsive need cpr and respiratory assistance immediately because of the effects of lightning on the respiratory center
- Determine what type of lightning injury this was (ground current, direct strike, splash)
- Evaluate the status of the storm and the current risk of additional strikes
- Put on your gloves and other protective equipment
Q7. You are dispatched to a scene for an 83 year old lady who is at home and cannot get up.
You arrive on scene to find a home that on the exterior is well kept. The scene appears safe and you enter the home. You find the rest of the house clean and things are put away but its summer, all the doors and windows have obviously been closed and the house is hot and stuffy. The patient is on the kitchen floor and there is a mess around her including urine and it looks like she might have also stooled herself. Her neighbor called 911 because she went to check on her after not seeing her out in the garden for the past 2 days which was unusual.
On initial evaluation, you have to really raise your voice to get the patient to open her eyes. When she does she asks you if you want some tea. She does not appear to be in any respiratory distress but is breathing quickly, she has a weak and fast radial pulse and her skin is hot and dry. Your initial assessment is this patient is sick given that she is confused and you call for additional resources. Which of the following are on the differential diagnosis for this patient? Choose all that apply
- Heat stroke
Q8. You obtain a set of vitals on the patient above once your establish her ABC’s are in tact. The patient has a heart rate of 120, a blood pressure of 80/60, and a respiratory rate of 28. The neighbor says the patient lives alone but hasn’t had any problems. She usually is alert, oriented and highly functional. The patient right now is unable to get up on her own and she tells you she is fine, just needs a hand to get up and that. Which of the following are true about your initial management and impression of this patient? Choose all that apply
- She likely doesn’t have a heat related problem because she has been down on the floor for a while and hasn’t been exerting herself
- Finding out if there are any medication bottles or other evidence of medical problems or medical wishes prior to leaving the house is a good use of time even though the patient is sick
- If she has a DNR form (not a MOST or MOLST form) you can leave her at home
- One indication for placing her on oxygen would be her fast breathing and altered mental status
Q9. You are concerned that this patient has heat stroke. What are the physical findings that would support heat stroke instead of heat exhaustion? Choose all that apply
- Age over 65
- Hot, dry skin
- Altered mental status
Q10. On a separate call, you find yourself called to a nursing facility who needs to be transported to the hospital for concern for a urine infection.
