Q

You are called to a minor traffic accident. One driver reports no injuries. The other driver’s car was hit on its side, and the occupant reports a “tearing” or “ripping” sensation in their lower back. The patient has a pulse of 112, BP 82/52, respirations 26, and has no neck tenderness on palpation. The most immediate concern is that this patient could have?

  1. An abdominal aortic aneurysm (AAA)
  2. A spinal injury that will require c-spine stabilization and a backboard
  3. Severe external bleeding that has not yet been discovered
  4. A spinal injury that will require only a neck collar and bandaging for any lacerations
A

An abdominal aortic aneurysm (AAA)

All symptoms are common of an AAA. The patient is showing signs of shock and denies any neck pain, making c-spine a lower priority than O2 therapy and immediate transport.

Lung sounds are clear on both sides, but heart tones are muffled. What do you suspect is going on with this patient?

  1. Cardiac tamponade
  2. Pulmonary embolism
  3. Tension pneumothorax
  4. Hemothorax
A

Cardiac tamponade

Trauma to the chest is a common cause of cardiac tamponade. This patient is exhibiting the classic signs of hypotension, JVD and muffled heart tones.

Q

How often should rescuers switch roles during CPR?

  1. Every two minutes or five cycles of CPR
  2. After every round of CPR
  3. Whenever the rescuers begin to feel fatigued
  4. Every five minutes
A

Every two minutes or every five cycles of CPR

It is important rescuers switch between compressions and breaths every two minutes to ensure high-quality CPR. If you become tired during CPR, chances are high that your compressions will become inadequate, reducing the victim’s chance of survival.

Q

How do you calculate cardiac output?

  1. Blood pressure x Heart rate
  2. Heart rate x Respiratory rate
  3. Stroke volume x Heart rate
  4. Stroke volume x Lung capacity
A

Stroke volume x Heart rate

Cardiac output is the amount of blood your heart pumps out in one minute. Stroke volume is the amount of blood pumped out to the body with every beat. To calculate cardiac output, you need to multiply the amount of blood pumped out during every beat by the heart rate.

Q

When performing adult CPR, how far should you compress the chest?

  1. At least two inches, not more than 2.4 inches
  2. 1.5 inches - 2 inches
  3. At least one inch
  4. 1/3 the depth of the torso
A

At least two inches, not more than 2.4 inches

The depth on an adult is at least 2” (not more than 2.4”) and the compression rate is 100 - 120/min. The key to good compressions is to ensure that you have proper recoil, allowing the chest to come back up completely before giving another compression.

Q

Arteries carry blood _____ the heart and veins bring blood _____ the heart

  1. Away from, Through
  2. Away from, Back to
  3. Back to, Away from
  4. Through, Away from
A

Away from, Back to

The Great Vessels are a combination of arteries and veins that allow blood flow between the heart, lungs, and the rest of the body. Arteries carry blood away from the heart and veins bring blood to the heart.

15
Q

Which of the following is correct in ranking the importance of CPR components during a pediatric arrest?

  1. Chest compressions, breathing, airway
  2. Airway, breathing, chest compressions
  3. Chest compressions, airway, breathing
  4. Airway, chest compressions. breathing
A

Chest compressions, airway, breathing

Chest compressions are the most important part of CPR as they circulate blood through the body and perfuse vital organs. Interruptions to chest compressions should be minimal (pulse check, shock delivery) and chest compressions should be resumed as soon as possible.

16
Q

Your patient is a 64-year-old female reporting 8/10 chest pain. Which finding most raises your index of suspicion for a cardiac history?

  1. A four-inch scar directly above the sternum
  2. Taking one 81 mg tablet of acetaminophen per day
  3. Blood pressure of 114/78
  4. HR of 82
A

A four-inch scar directly above the sternum

A scar above the heart can be a sign that the patient has had a major cardiac surgery in the past. Both the BP and HR are within normal limits, and although taking a daily aspirin can be a sign of a cardiac history, it alone is not indicative of major heart problems.

17
Q

How many valves does the heart have?

  1. 4
  2. 3
  3. 2
  4. 5
A

4

The heart has four valves. Tricuspid, Bicuspid (mitral), Aortic, Pulmonary.

18
Q

Which of the following BEST describes Pericarditis?

  1. Inflammation affecting all of the lung tissue
  2. Inflammation affecting the innermost layer of the heart
  3. Inflammation affecting the outermost layer of the heart
  4. Inflammation affecting the muscle tissue of the heart
A

Inflammation affecting the outermost layer of the heart4

Pericarditis is the inflammation affecting the pericardium, which is the lining surrounding the heart, responsible for enclosing it and protecting it from surrounding structures.

19
Q

Which one of these statements about compression depth is true?

  1. You should push hard and fast, erring on the side of going too deep rather than too shallow
  2. Making sure not to compress the chest too deep ensures that the victim will not have permanent chest wall damage
  3. Compression depth is not nearly as important as giving proper breaths
  4. You should compress the chest wall just enough to see a slight impression on the victim’s chest
A

You should push hard and fast, erring on the side of going too deep rather than too shallow

When CPR is being performed, the goal is to pump blood to the vital organs; this can be directly hindered by not compressing the chest deep enough. Proper CPR is crucial to a victim’s chance of survival.

20
Q

Brain damage begins roughly how long after the patient suffers cardiac arrest?

  1. 8-10 minutes
  2. 1-2 minutes
  3. 4-6 minutes
  4. 12-15 minutes
A

4-6 minutes

Brain damage begins roughly 4-6 minutes after patients experience cardiac arrest. Circulating blood and getting oxygen to the brain is why good chest compressions are so vital during cardiac arrest.

21
Q

You are driving your ambulance to the ER while your partner is treating a middle-aged man in the back of the ambulance for an AMI. He has been stabilized, is on high-flow oxygen, and is conscious. After a brief commotion, your partner informs you that the patient has lost consciousness and his EKG reading is indicating cardiac arrest. You are 10 minutes out from the hospital. What should you do?

  1. Request additional resources, pull over and help your partner with CPR
  2. Request additional resources to meet at a specified location
  3. Have your partner apply 15 Lpm of high-flow oxygen
  4. Increase your speed slightly and go emergent
A

Request additional resources, pull over and help your partner with CPR

Cardiac arrest is a life threat that needs to be dealt with immediately and because the time from ER is so significant, the patient’s best chance of survival depends on immediate compressions.

22
Q

Which of the following is a contraindication for Nitroglycerin administration?

  1. Tachycardia
  2. Bradycardia
  3. Hypertension
  4. Hypotension
A

Hypotension

Due to the vasodilator effects of nitroglycerin, it is important to assess the patient’s blood pressure prior to administration. Patients who are experiencing hypotension should not take nitroglycerin because it may worsen their hypotension.

23
Q

Your ALS partner suspects the patient you are treating is experiencing cardiogenic shock. Which of the following presentations would your patient most likely not have?

  1. Pulmonary edema with wheezes or rales
  2. Slow heart rate
  3. Hives
  4. Chest pain
A

Hives

24
Q

The left atrium is responsible for which of the following actions?

  1. Pumping blood to the lungs
  2. Receiving blood from the lungs
  3. Pumping blood to the body
  4. Receiving blood from the veins of the body
A

Receiving blood from the lungs

The left atrium is responsible for receiving blood from the lungs. This blood is oxygenated.

25
Q

If your patient is experiencing 10/10 chest pain but states that they get hives when they take Aspirin, you should?

  1. Administer a half-dose of Aspirin
  2. Withhold Aspirin
  3. Administer Aspirin
  4. Administer only one tablet of Aspirin (81mg)
A

Withhold Aspirin

A contraindication of Aspirin administration is an allergic reaction or sensitivity to the drug.

26
Q

While performing chest compressions, what should you allow time for after each compression?

  1. Recoil
  2. Rhythm check
  3. Delivery of ventilations
  4. Pulse check
A

Recoil

You want to ensure that every time you deliver a chest compression you are allowing for proper recoil of the chest wall.

27
Q

The sinoatrial node is also called the?

  1. The left ventricle
  2. The pacemaker of the heart
  3. The electrical conduction system of the heart
  4. The bundle branch of the heart
A

The pacemaker of the heart

The sinoatrial node generates nerve impulses that allow the heart to fire or contract.

28
Q

After you have checked your patient for responsiveness during the BLS survey, what is your next course of action?

  1. Deliver two rescue breaths
  2. Attach the AED
  3. Start compressions
  4. Activate the emergency response system and get an AED
A

Activate the emergency response system and get an AED

If you are able , you should get an AED after activating the emergency response system. If someone is available, you can send them to do this for you.
