Sudden cardiac arrest is an abrupt occurrence where the heart ceases to function and results in death within minutes. According to the explanation of Basic CPR, what is the first step to begin administering CPR? Call 911 Give two breaths Check pulse Start Compressions

What will CPR do to help a person in cardiac arrest?increase action potential in the hearttemporarily supply body with oxygen until help arrivesdecrease action potential

1. What are the vital characteristics of first-rate CPR?Starting chest compressions within 10 seconds of recognition of cardiac arrestMinimizing interruptionsPushing hard and fastAll of the above2. What should you do if the individual chest is wet when using an AED?Quickly wipe it dry before proceeding with AED use.Do not use an AED device.Proceed with AED use as usual.Rub isopropyl alcohol on the individual skin before proceeding with AED use.3. Why are breaths so important for children and infants in cardiac arrest?Because they often have respiratory failure that reduces the oxygen content in the blood before the onset of arrest.Because breaths help to dislodge foreign bodies.Because they have smaller lungs.None of the above4. In both children and infants, the compression to ventilation ratio for two-rescuer CPR is:15:230:130:215:15. When looking for a pulse on a child from one year to puberty, where should you check?Popliteal arteryCarotid or femoral arteryBrachial arteryTemporal artery

Always begin each CPR cycle with compressions unless is the suspected cause of cardiac arrest, then deliver prior to compressions.

What is the next step when an adult choking individual becomes unresponsive?Check for pulse.Defibrillate.Give rescue breaths.Activate the emergency response system.3.

An AED can be used in which of the following special situations?Individual with an implanted pacemakerIndividual with an hairy chestIndividual with a transdermal medication patch onAll of the above5. Which of the following may be essential to maintaining an individual's open airway?Rescue breathsO2 administrationChest thrustsSuctioning6. Which of the following would be your next call to action if the rhythm is unshockable, and there is no pulse?Administer atropine if the individual has a fast heart rate.Resume CPR and prepare AED to administer a shock.Immediately resume CPR.None of the above7. What are the BLS (Basic Life Support) steps used for adults?Assess the individual, activate EMS and get AED, check pulse, and start CPRAssess the individual, give two rescue breaths, defibrillate, and start CPRCheck pulse, give rescue breaths, assess the individual, and defibrillateNone of the above8. What is the compression to ventilation ratio you should use when giving CPR to any adult?15:215:130:230:19. What is the appropriate way to clear an object from an infant’s airway?Blind finger sweepAbdominal thrustsBack blows and chest thrustsNone of the above10. Signs of severe airway obstruction include which of the following?Poor air exchangeHigh-pitched noise while inhalingInability to speakAll of the above11. What is the recommended BLS sequence for the 2020 ILCOR guidelines?Chest compressions, Airway, BreathingAirway, Breathing, Chest compressionsAirway, Breathing, Check PulseNone of the above12. When looking for a pulse on a child from one year to puberty, where should you check?Popliteal arteryCarotid or femoral arteryBrachial arteryTemporal artery13. Which step is NOT a part of the six steps in the Adult Chain of Survival?Early CPRRapid defibrillationIntegrated post-cardiac arrest careAdvanced airway placement14. All of the following are goals of resuscitation EXCEPT:Decrease glucose level.Increase survival rates.Provide CPR as a team.Minimize interruptions in CPR.15. What does BLS prioritize?A. Early high-quality CPRB. Immediate IV accessC. Delayed defibrillationD. Both A and C16. Which of the following is true regarding BLS?It should be mastered prior to ACLS.It has little impact on survival.It is obsolete.Recent changes prohibit mouth-to-mouth.17. When operating an AED, what are the correct steps to follow?Power on the AED, attach electrode pads, shock the individual, and analyze the rhythmPower on the AED, attach electrode pads, clear the individual, analyze the rhythm, and deliver shockAttach electrode pads, check pulse, shock the individual, and analyze rhythmNone of the above18. The rescuer's exhaled air contains approximately _____ oxygen and _____ carbon dioxide.6%, 12%10%, 8%21%, 2%17%, 4%19. At what age is it necessary to use the child AED pads?13 years of age or younger8 years of age or older10 years of age or youngerLess than 8 years of age20. In both children and infants, the compression to ventilation ratio for two-rescuer CPR is:15:230:130:215:121. You are alone when you encounter an adult with cardiac arrest. Individual is not breathing, has no pulse, and has no suspected cervical spine trauma. Which maneuver should you use to open the airway?Head-tilt-chin-lift maneuverHead-tilt maneuver onlyJaw-thrust maneuverBlind finger-sweeps22. You are alone when you encounter an individual in what appears to be cardiac or respiratory arrest. What are the first three steps you should take to stabilize the individual? Check for danger, check for response, and ____________.Activate EMS.Administer an initial shock.Start CPR.Insert an advanced airway.23. Thirty ____________ and two ____________ equal one cycle of CPR.chest compressions, jaw thrustschest compressions, pulse checksbreaths, chest compressionschest compressions, breaths24. Rescue breaths for children and infants should be administered how often?Every 2 to 3 seconds (20 to 30 breaths per minute)Every 5 to 6 seconds (10 to 12 breaths per minute)Every 10 to 12 seconds (5 to 6 breaths per minute)Every 20 to 30 seconds (2 to 3 breaths per minute)25. With an advanced airway in place during two-rescuer CPR for an adult, how often should breaths administered?

Once you begin CPR, you must continue until any of the following occurs EXCEPT:You are too tired to continue.Someone with equal or greater training takes over for you.EMS arrives and takes over.20 minutes have passed.
