#1
What does CPR stand for?
Cardiopulmonary Resuscitation
ExplanationEmergency procedure to manually preserve brain function until further measures can restore spontaneous blood circulation and breathing.
#2
What is the first step in the CPR sequence?
Check for responsiveness
ExplanationDetermines if the victim is conscious and in need of immediate assistance.
#3
What does the acronym AED stand for in the context of CPR?
Automated External Defibrillator
ExplanationDevice used to analyze heart rhythm and deliver electric shock if necessary.
#4
What is the correct hand placement for chest compressions in adult CPR?
Lower half of the sternum
ExplanationMaximizes effectiveness by compressing the heart directly.
#5
What is the purpose of the head tilt-chin lift maneuver in CPR?
To open the airway
ExplanationFacilitates airflow by preventing obstruction of the upper airway.
#6
In CPR, what is the recommended depth of chest compressions for an adult?
2 inches
ExplanationDepth required to adequately circulate blood without causing unnecessary damage.
#7
What is the ratio of chest compressions to rescue breaths in CPR for adults?
20:2
ExplanationMaintains oxygenation while circulating blood to vital organs.
#8
In pediatric CPR, what is the recommended depth of chest compressions?
1 inch
ExplanationSufficient to maintain blood circulation without causing harm.
#9
What is the purpose of the recovery position in CPR?
To maintain an open airway
ExplanationPrevents obstruction of the airway and facilitates breathing.
#10
In CPR, what is the purpose of checking for a pulse?
To confirm cardiac arrest
ExplanationDetermines if CPR is necessary and guides appropriate intervention.
#11
What is the recommended compression depth for infant CPR?
0.5 inches
ExplanationSufficient to circulate blood without causing harm to infants.
#12
Why is it important to ensure the victim's airway is open during CPR?
To allow air to enter the lungs
ExplanationCritical for oxygenation and respiration during resuscitation.
#13
What is the purpose of rescue breaths in CPR?
To provide oxygen to the lungs
ExplanationCritical for maintaining oxygenation and supporting vital functions.
#14
Why is it essential to place the heel of the hand on the lower half of the sternum during chest compressions?
To maximize compression depth
ExplanationEnsures effective circulation by directly compressing the heart.
#15
What is the primary purpose of bystander CPR?
To provide immediate care until professional help arrives
ExplanationIncreases survival rates by initiating timely intervention.
#16
Which of the following is a common AED placement for pads during CPR?
Upper right chest and lower left chest
ExplanationAllows efficient delivery of electric shock to restore normal heart rhythm.
#17
During CPR, what should you do if the chest does not fully recoil after each compression?
Decrease compression depth
ExplanationPrevents impeding blood flow during chest compressions.
#18
Which of the following is a sign that CPR is effective?
The victim's chest rises with each breath
ExplanationIndicates successful delivery of rescue breaths and adequate circulation.
#19
What is the recommended rate of chest compressions per minute in adult CPR?
100-120
ExplanationOptimal rate to maintain blood flow and oxygenation.
#20
What is the primary goal of early defibrillation in CPR?
To restore a normal heart rhythm
ExplanationCritical to reversing potentially fatal arrhythmias.
#21
In adult CPR, what is the recommended compression-to-ventilation ratio?
15:2
ExplanationBalances oxygenation and circulation for optimal resuscitation.
#22
Which of the following is a common cause of cardiac arrest?
Choking
ExplanationCan lead to airway obstruction and cessation of breathing.
#23
What is the recommended compression depth for child CPR?
1 inch
ExplanationSufficient to circulate blood without causing harm to children.
#24
During infant CPR, where should chest compressions be performed?
Upper chest
ExplanationOptimal placement to avoid harm to infants' delicate structures.
#25
What is the recommended rate of rescue breaths per minute for adult CPR?
12-14
ExplanationMaintains oxygenation while minimizing interruptions in chest compressions.
