  • Ventricular fibrillation
  • Pulseless ventricular tachycardia
  • The sino-atrial node
What will you do to assess the pulse of an adult victim?

  • Check the carotid pulse for 5 to 10 seconds
  • Check the carotid artery pulse for at least 20 seconds
  • Checking the pulse is not necessary for adult victims
After offering resuscitation in the event of a cardiac arrest and your patient starts breathing, what's the best recovery position to put them in to maintain a clear airway?
  • In a still position
  • In a left lateral position
  • In a stable true lateral position, head-dependent on something and no pressure on the chest
  • In a stable true lateral position, head-dependent on something with pressure on the chest
What is the correct position to perform abdominal thrusts on a child?
  • Standing in front of the child
  • Standing behind the child with one foot in front of the other
  • Kneeling in front of the child
  • Kneeling on the left side of the child
What is the compressions to ventilation ratio for unconscious infant choking?
  • 5 compressions, 5 rescue breaths
  • 3 compressions, 1 rescue breath
  • 10 compressions, 2 rescue breath
  • 30 compressions, 2 rescue breaths
What is the action stated in rapid defibrillation?
  • AED should be used as soon as it's available
  • Use the AED when the victim doesn't have a pulse
  • Obtain permission first before using AED
  • Use AED after 10 cycles of CPR
What is Integrated post-cardiac arrest care?
  • Early use of an AED after a cardiac arrest
  • Providing high-quality CPR as soon as cardiac arrest is detected
  • Comprehensive system of care, including mild therapeutic hypothermia and other treatments.
  • Treatment of potential cardiac problems after the victim was resuscitated
What is the first thing you should do when you did not witness the infant collapse?
  • Perform 2 minutes of CPR
  • Call 911
  • Perform chest compression
  • Provide rescue breathing
Which of the following is true about AEDs and pacemakers?
  • AEDs can interfere with pacemakers, so the pads should not be placed directly on pacemakers.
  • AED pads should be placed directly over the pacemakers.
  • You don't need to worry about pacemakers when using an AED.

How should you open the airway of an unconscious choking victim?
  • Head tilt and chin lift.
  • Jaw thrust.
  • Head tilt and jaw thrust.
  • Lift the chin.

  • Call 911
According to the 2020 guidelines, what are the recommended steps when giving CPR to cardiac arrest patients?
  • Airway, Breathing, Chest compressions
  • Chest compressions, Airway, Breathing
  • Airway, Breathing, Check pulse
  • Check pulse, Airway, Breathing
What are the vital characteristics of high-quality CPR?
  • The victim's airway is opened, and the rescuer begins breathing into the victim's mouth
  • The rescuer provides 30 chest compressions followed by 2 rescue breaths
  • The rescuer pushes hard and fast in the center of the victim's chest
  • The rescuer checks for signs of life after 2 minutes of CPR
Rescue breathing is given to adults at the rate of:
  • 1 breath every 10-12 seconds
  • 1 breath every 5-6 seconds
  • 1 breath every 3-5 seconds
  • 2 breaths every 5-6 seconds
What should you do if the chest doesn't rise and fall when you give the first rescue breath?
  • Immediately shift to abdominal thrusts and perform thrusts
  • Reposition the victim's head, then use the head tilt chin lift maneuver again to open the airway and give the 2nd rescue breath.
  • Sit the guest upright and administer back blows until the object is dislodged
  • Perform a finger sweep and then attempt to ventilate again
What is the most important thing to remember when using a pocket mask?
  • Make sure the patient's nose and mouth are covered
  • Ensure a tight seal around the patient's face
  • Only use if supplemental oxygen is available
  • Use a one-way valve to prevent disease transmission

  • 5 cycles
  • 3 cycles
  • 4 cycles
  • 8 cycles
Which of the following best describes Opioids?

  • Opioids relieve mild or moderate pain, such as headaches and toothache
