‍

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

‍

You are guiding someone over the phone to perform CPR on a victim who has collapsed. What is the first thing you instruct them to do?

• Tell them to begin chest compressions immediately.
• Instruct them to check for responsiveness and call emergency services.
• Tell them to look for an AED before starting CPR.
• Instruct them to give rescue breaths firs

‍

You come across a person in cardiac arrest who is also bleeding heavily. How do you manage both the cardiac arrest and the bleeding?

• Focus on CPR first and leave the bleeding unattende
• Stop CPR and manage the bleeding until it’s controlled, then resume CPR.
• Perform CPR while using a tourniquet or direct pressure to control the bleeding.
• Ignore the bleeding and wait for professional help.

‍

A victim has gone into cardiac arrest but also has a suspected spinal injury. How do you perform CPR while minimizing further damage to the spine?

• Perform chest compressions normally, ensuring the head and neck stay still.
• Avoid CPR to prevent further spinal injury.
• Use an AED only and avoid chest compressions.
• Provide CPR with as minimal head movement as possible, supporting the neck during any airway adjustments.

‍

You are performing BLS during a heatwave. How would you adjust your approach?

• Begin CPR immediately without considering the environmental conditions.
• Move the victim to a cooler or shaded area, if possible, before starting CPR.
• Provide less intense compressions to avoid heat exhaustion for yourself.
• Skip rescue breathing to avoid the spread of heat-induced illness.

‍

The victim has a pacemaker. How do you modify chest compressions during CPR?

• Avoid chest compressions to prevent damaging the pacemaker.
• Perform compressions directly over the pacemaker.
• Position your hands slightly away from the pacemaker and perform compressions as usual.
• Skip compressions and focus on rescue breathing.

‍

The victim is experiencing chest pain, shortness of breath, and has a history of heart disease. What is the likely cause of cardiac arrest, and how does that change your approach to BLS?

• Suspected myocardial infarction, continue CPR and use an AED as soon as possible.
• Stroke, focus on rescue breathing and avoid compressions.
