#1
Which of the following is a primary goal of Basic Life Support (BLS)?
To restore normal breathing
ExplanationBLS aims to restore normal breathing in emergency situations.
#2
What is the purpose of the recovery position in first aid?
To maximize blood flow to the brain
ExplanationThe recovery position maximizes blood flow to the brain, aiding recovery.
#3
What does the term 'AED' stand for in the context of emergency response?
Automated External Defibrillator
ExplanationAED stands for Automated External Defibrillator, used for emergency cardiac care.
#4
What is the correct hand placement for chest compressions in adult CPR?
Lower half of the sternum, just above the xiphoid process
ExplanationCorrect hand placement ensures effective compression over the sternum.
#5
What is the first step in the BLS algorithm for a healthcare provider encountering an unresponsive victim?
Check for responsiveness
ExplanationThe first step is assessing responsiveness to determine the need for CPR.
#6
What is the recommended depth for chest compressions in adult CPR?
2 inches (5 centimeters)
ExplanationRecommended depth ensures effective compression for adult CPR.
#7
During team resuscitation, what is the primary role of the team leader?
Coordinating and directing the team's actions
ExplanationThe team leader coordinates and directs actions during resuscitation efforts.
#8
What does the acronym 'C-A-B' stand for in the context of CPR?
Circulation, Airway, Breathing
ExplanationC-A-B represents the sequence of priorities in CPR: Circulation, Airway, Breathing.
#9
Which of the following is a common cause of cardiac arrest?
Heart attack
ExplanationHeart attack is a common cause of sudden cardiac arrest.
#10
What is the recommended compression rate for adult CPR?
100 compressions per minute
ExplanationRecommended rate ensures adequate blood circulation during adult CPR.
#11
During CPR, where should chest compressions be delivered on an adult victim?
Over the sternum, between the nipples
ExplanationChest compressions should be centered over the sternum for effective CPR.
#12
Which of the following actions is NOT part of the initial assessment in BLS?
Starting chest compressions immediately
ExplanationImmediate chest compressions are not initially recommended in BLS assessment.
#13
What is the recommended compression-to-ventilation ratio for adult CPR?
30:2
ExplanationRecommended ratio balances compression and ventilation for effective adult CPR.
#14
In the chain of survival, what is the role of early defibrillation?
To deliver a shock to restore normal heart rhythm
ExplanationEarly defibrillation aims to restore normal heart rhythm promptly.
#15
In BLS, what is the purpose of checking for a pulse?
To verify cardiac arrest
ExplanationChecking for a pulse confirms the absence of cardiac activity, indicating arrest.
#16
What is the recommended compression-to-ventilation ratio for infant CPR?
15:2
ExplanationRecommended ratio balances compression and ventilation for effective infant CPR.
#17
What is the purpose of the jaw thrust maneuver during CPR?
To manually open the airway while minimizing movement of the neck
ExplanationJaw thrust maneuver aids airway opening with minimal neck movement during CPR.
