Question

   • None of the above
5. The initial Basic Life Support (BLS) steps for adults are:
   • Assess the individual, give two rescue breaths, defibrillate, and start CPR
   • Check pulse, give rescue breaths, assess the individual, and defibrillate
   • None of the above

   • After every 10 cycles of CPR
   • After every five cycles of CPR
   • After every cycle of CPR
   • After every 15 cycles of CPR
8. In both children and infants, the compression to ventilation ratio for two-rescuer CPR is:
   • 30:01:00
   • 15:01
   • 15:02

9. Where should you attempt to perform a pulse check in a child from one year of age to puberty?
   • Temporal artery
   • Popliteal artery

    • Brachial artery
    • Popliteal artery
    • Temporal artery
    • Carotid or femoral artery
11. 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 they have smaller lungs.
    • Because breaths help to dislodge foreign bodies.
    • None of the above
12. The rescuer’s exhaled air contains approximately _____ oxygen and _____ carbon dioxide.

    • Back slaps
    • Finger sweep
    • None of the above
    • Abdominal thrusts (Heimlich maneuver)
15. What is the next step when an adult choking individual becomes unresponsive?
    • Check for pulse.
    • Activate the emergency response system.
    • Defibrillate.

    • Insert an advanced airway.
    • Administer an initial shock.
    • Start CPR.
    • Activate EMS.
19. Which of the following may be essential to maintaining an individual’s airway open?
    • An advanced airway
    • Rescue breaths
    • O2 administration
    • Chest thrusts
20. Thirty ____________ and two ____________ equal one cycle of CPR.
    • chest compressions, breaths
    • chest compressions, jaw thrusts
    • chest compressions, pulse checks
    • breaths, chest compressions
21. Which of the following would be your next call to action if the rhythm is unshockable, and there is no pulse?
    • Resume CPR and prepare AED to administer a shock.
    • Administer atropine if the individual has a fast heart rate.
    • None of the above
    • Immediately resume CPR.

Answer 1

Answer: False

( This is because when the heart is in VF state, it recieves the nurve impulses from the brain which are so intense that no heart rate can be produced).

Answer: Starting chest compressions within 10 seconds of recognition of cardiac arrest.

( The critical characteristics of high quality of CPR includes that starting chest compression within 10 seconds of recognition of cardiac arrest)

Answer: Advanced airway placement

( The advanced airway placement is not included in the five links in adult chain survival. )

Answer:Airway, Breathing, Chest compressions

( The first action includes mkaing airway passage then breathing and then the chest compression.)
