#1
What is the first step in the Basic Life Support (BLS) algorithm?
Check for responsiveness
ExplanationAssessing if the person is conscious.
#2
What is the ratio of compressions to breaths during CPR for adults?
30:2
ExplanationOptimal ratio for maintaining oxygenation and circulation.
#3
Which of the following is a common cause of cardiac arrest?
Arrhythmia
ExplanationDisruption in the heart's rhythm, leading to ineffective pumping.
#4
What is the recommended compression rate for infant CPR?
100-120 compressions per minute
ExplanationMaintaining adequate circulation for infants' smaller bodies.
#5
What is the preferred method to open the airway during CPR?
Head tilt-chin lift
ExplanationEnsuring a clear passage for air into the lungs.
#6
What is the recommended rate for chest compressions during CPR in adults?
100 compressions per minute
ExplanationMaintaining a consistent rhythm for effective circulation.
#7
What does the acronym AED stand for in relation to resuscitation?
Automatic External Defibrillator
ExplanationA device to deliver a shock to the heart to restore normal rhythm.
#8
During CPR, where should you place your hands for chest compressions on an adult?
Over the lower half of the sternum
ExplanationOptimal position for effective compression of the heart.
#9
What is the recommended compression depth for adult CPR?
At least 2 inches
ExplanationSufficient depth to effectively compress the heart for circulation.
#10
What should you do first if you find an unresponsive person?
Call for help
ExplanationInitiating assistance to manage the emergency effectively.
#11
Which of the following is NOT a sign of effective chest compressions during CPR?
Cracking sound in the chest
ExplanationIndicates possible injury and ineffective compression technique.
#12
Which of the following is a step in the Chain of Survival for cardiac arrest?
Defibrillation within 2 minutes
ExplanationCritical intervention to restore normal heart rhythm promptly.
#13
Which of the following is NOT a common cause of pediatric cardiac arrest?
Hypertension
ExplanationNot typically a primary cause of sudden cardiac arrest in children.
#14
Which of the following is NOT an indication to stop CPR?
Fatigue of the rescuer
ExplanationRescuer's fatigue doesn't override the need for continued resuscitation.
#15
What should you do if the victim of a cardiac arrest has a suspected neck injury?
Perform chest compressions only
ExplanationMinimizing movement to prevent potential spinal cord damage.
