HEARTCODE BLS EXAM STUDY GUIDE 2026
FULL QUESTIONS AND SOLUTIONS
◉How are breaths delivered using a bag-mask device? Answer: 1
breath over 1 second, while watching for chest rise
◉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 ventricular Fibrillation
(VF) where the heart's electrical impulses suddenly become chaotic
and ineffective
- 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
◉Why is an AED needed? Answer: To analyze the heart rhythm and
provide a shock
,◉After an AED delivers a shock, what should the rescuers do next?
Answer: Resume CPR, starting with chest compressions
◉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 charge 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
◉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
◉AED pad placement: Adults and children 8 years and older.
Answer: 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
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
◉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
◉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 send that
person to get it
