BLS HeartCode Online Questions and Answers
1. After positioning yourself directly above the victim's head, what is the correct order of
steps for using a bag-mask device?
Answer 1. Place the mask on the victim's face, using the bridge of the nose as a guide for the correct position
2. Use the E-C clamp technique to hold the mask in place while you lift the jaw to hold the airway open
3. Squeeze the bag to give breaths (1 second each) while watching for chest rise
2. How are breaths delivered using a bag-mask device?
Answer 1 breath over 1 second, while watching for chest rise
3. Why an AED is needed
Answer - Most sudden cardiac arrests are triggered by abnormal heart rhythms called arrhythmias
-Two life-threatening arrhythmias that can cause cardiac arrest are pulseless ventricular tachycardia(pVT) and ventric- ular
Fibrillation (VF) where the heart's electrical impulses suddenly become chaotic and inettective
-Blow flow to the brain stops abruptly, and the victim loses consciousness
-Death usually follows unless a normal heart rhythm and pulse are restored within minutes
4. Why is an AED needed?
1/

, Answer To analyze the heart rhythm and provide a shock
5. After an AED delivers a shock, what should the rescuers do next?
Answer Resume CPR,
starting with chest compressions
6. How to Use an AED
Answer Step 1
Power on the AED if needed
-Follow the prompts (as a guide to next steps)
Step 2
Choose adult pads for victim 8 years of age and older
-Attack the adhesive AED pads to the victim's bare chest
-Follow the diagrams on the pads
Step 3
When AED prompts you, clear the victim during analysis. Be sure no one is touching the victim, not even the rescuer in charg
of giving breaths
-Some AEDs will tell you to push a button to allow the AED to begin analyzing the heart rhythm; others will do
automatically
-The AED may take a few seconds to analyze
Step 4

,If the AED advises a shock
-it will charge and then tell you again to clear the victim
-Clear the victim before delivering the shock
-Pressure the shock button
-The shock will produce a sudden contraction of the victim's muscles
-After any shock delivery, immediately resume CPR
If no shock is needed
-Immediately resume CPR, starting with compressions
7. Where should the AED pads be placed in the anterolateral placement for adults
and children 8 years or older?
Answer -Below the right collarbone
-Side of left nipple
8. AED pad placement Adults and children 8 years and older
Anterolateral Placement
-place one pad directly bellow the right collarbone
-Place the other pad to the side of the left nipple, with the top edge of the pad a few inches below the armpit
3/

, Anteroposterior placement
-Place one AED pad on the left side of the chest, halfway between the tip of the breastbone and left nipple with upper edge
of the pad below the nipple line
-Place the other pad on the left side of victim's back, beneath the should blade, next to the spine
9. What is recommended to minimize interruptions in compressions when using an AED?
Answer - Continue with a high-quality CPR until an AED prompts to clear
-If no shock is advised and after any shock delivery, immediately resume high-quality CPR, starting with chest
compressions
-When 2 or more rescuers are present, one rescuer should continue chest compressions while the other prepares the
AED
10. Scene Safety, Responsive and Assessment
Answer The first step in the adult BLS sequence for 1 or 2
or more rescuers is to verify the scene is safe
Check for responsiveness and get help. Tap the victim's should and shout, "Are you OK?
If the victim is not responsive, shout for nearby help. If you are alone get the AED/defibrillator; if someone else is available se
that person to get it
