#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
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.
#14
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.
#15
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.
#16
What is the recommended rate of chest compressions per minute in adult CPR?
100-120
ExplanationOptimal rate to maintain blood flow and oxygenation.
#17
What is the primary goal of early defibrillation in CPR?
To restore a normal heart rhythm
ExplanationCritical to reversing potentially fatal arrhythmias.
#18
In adult CPR, what is the recommended compression-to-ventilation ratio?
15:2
ExplanationBalances oxygenation and circulation for optimal resuscitation.
#19
Which of the following is a common cause of cardiac arrest?
Choking
ExplanationCan lead to airway obstruction and cessation of breathing.
