What is the purpose of an Automated External Defibrillator (AED) during a cardiac emergency?
To restore normal heart rhythm by delivering an electric shock.
ExplanationAEDs aim to correct abnormal heart rhythms through controlled shocks.
#3
What is the recommended compression-to-ventilation ratio for adult CPR?
30 compressions to 1 ventilation
ExplanationMaintain a ratio of 30 compressions to 1 ventilation during adult CPR.
#4
Where should you place the pads of an AED on the victim's body?
One pad on the upper right chest, and the other on the lower left chest.
ExplanationProper pad placement ensures effective AED intervention.
#5
What is the recommended rate for chest compressions during CPR for adults?
80-100 compressions per minute
ExplanationMaintain a compression rate of 80-100 per minute for effective adult CPR.
#6
Which of the following is NOT a common symptom of a cardiac emergency?
Persistent hiccups
ExplanationPersistent hiccups are not indicative of a typical cardiac emergency.
#7
During the use of an AED, when should you avoid touching the patient?
After analyzing heart rhythm.
ExplanationRefrain from contact during AED analysis for accurate assessment.
#8
What is the recommended depth for chest compressions in adult CPR?
2 inches (5 centimeters)
ExplanationCompression depth of 2 inches aids effective cardiac pumping.
#9
Which of the following statements about AED use is true?
AEDs should not be used on infants younger than 1 year old.
ExplanationExercise caution with AED use on infants, avoiding application under 1 year.
#10
What is the first step you should take if you witness someone collapse and suspect a cardiac arrest?
Call for emergency medical help.
ExplanationPromptly summon professional assistance when suspecting cardiac arrest.
#11
What does 'AED' stand for?
Automated External Defibrillator
ExplanationAED stands for Automated External Defibrillator.
#12
During CPR, how should you position your hands for chest compressions?
Place the heel of one hand on the center of the chest.
ExplanationOptimal hand placement involves the heel on the center of the chest.
#13
Which rhythm is most commonly treated with defibrillation during a cardiac arrest?
Ventricular Fibrillation
ExplanationDefibrillate promptly in cases of Ventricular Fibrillation for optimal outcomes.
#14
During CPR, how should you position the victim's head to open the airway?
Tilt the head back and lift the chin.
ExplanationEnsure proper airway alignment by tilting the head and lifting the chin.
#15
Which of the following is a common cause of sudden cardiac arrest?
Electric shock
ExplanationElectric shock is a recognized cause of sudden cardiac arrest.
#16
What is the recommended depth for chest compressions during CPR for infants?
1/2 inch (1.25 centimeters)
ExplanationUse a compression depth of 1/2 inch for effective infant CPR.
#17
Which of the following rhythms indicates a non-shockable cardiac arrest rhythm?
Asystole
ExplanationAsystole is a non-shockable rhythm during cardiac arrest.
