#1
What does AED stand for?
Automated External Defibrillator
ExplanationA device that analyzes heart rhythm and delivers a shock to restore normal rhythm.
#2
Which of the following is a common sign of sudden cardiac arrest?
Loss of consciousness
ExplanationTypically the first noticeable symptom, indicating a cardiac emergency.
#3
When should you use an AED on a person experiencing a cardiac arrest?
As soon as it is available
ExplanationPrompt application increases chances of survival.
#4
What is the primary purpose of CPR in a cardiac arrest situation?
To maintain oxygen supply to the brain and vital organs
ExplanationSustains life until normal heart function can be restored.
#5
When performing CPR on an adult, how should you position your hands for chest compressions?
Both hands on the lower half of the sternum
ExplanationMaximizes effectiveness of compressions over the heart.
#6
During CPR, what is the recommended compression depth for adults?
2 inches
ExplanationTo adequately compress the chest and circulate blood effectively.
#7
What is the first step to take when you find an unresponsive person?
Call for emergency help
ExplanationCritical to ensure timely arrival of professional assistance.
#8
What is the purpose of using an AED during a cardiac emergency?
To restore normal heart rhythm
ExplanationIts primary function is to reset the heart's electrical rhythm.
#9
Which part of the body should you place the AED pads for effective defibrillation?
Chest
ExplanationDirectly on the chest to deliver the electrical shock.
#10
What is the recommended depth for chest compressions in infant CPR?
0.5 inches
ExplanationDelicate infant physiology requires gentle but effective compressions.
#11
Which of the following is a potential complication of performing CPR on a person with a pulse?
Fractured ribs
ExplanationExcessive force can lead to bone damage despite a pulse.
#12
During infant CPR, where should chest compressions be performed?
Over the lower half of the sternum
ExplanationEnsures effective compression of the heart to circulate blood.
#13
How does an AED determine if a shock is needed?
By analyzing the heart rhythm
ExplanationAssesses the rhythm to decide if a shock is necessary for restoring normalcy.
#14
What is the ratio of chest compressions to rescue breaths in CPR for adults?
30:2
ExplanationOptimal balance for circulating blood and providing oxygen.
#15
In CPR, what is the recommended rate of chest compressions per minute for adults?
80-100
ExplanationMaintains adequate blood flow and oxygenation during resuscitation.
#16
What should you do if the AED pads are wrinkled or damaged?
Replace them with new ones
ExplanationEnsures effective conduction of the electrical shock.
#17
What is the recommended compression-to-ventilation ratio for one-rescuer infant CPR?
15:2
ExplanationBalances oxygenation and circulation effectively in infants.
#18
In the context of AED usage, what does the acronym 'PAD' stand for?
Public Access Defibrillator
ExplanationAEDs available for public use in various locations.
#19
Why is it important to minimize interruptions in chest compressions during CPR?
To maintain blood circulation
ExplanationEnsures continuous flow of oxygenated blood to vital organs.
