QUESTIONS WITH CORRECT ANSWERS
After positioning yourself directly above the victim's head, what is the correct order of steps for using
a bag-mask device? - CORRECT 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
How are breaths delivered using a bag-mask device? - CORRECT ANSWER -
1 breath over 1 second, while watching for chest rise
Why an AED is needed - CORRECT 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 ve
ntricular Fibrillation (VF) where the heart's electrical impulses suddenly become chaotic and ineffectiv
e
- 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? - CORRECT ANSWER -To analyze the heart rhythm and provide a shock
After an AED delivers a shock, what should the rescuers do next? - CORRECT ANSWER -
Resume CPR, starting with chest compressions
How to Use an AED - CORRECT 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 victi
m, 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; oth
ers 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? - CORRECT ANSWER --Below the right collarbone
