#1
What is the first step in basic life support (BLS) for an unresponsive victim?
Check for responsiveness
ExplanationInitiate BLS by ensuring the victim is unresponsive and in need of assistance.
#2
Which of the following is a common symptom of a heart attack?

#3
What does AED stand for in the context of emergency care?
Automated External Defibrillator
ExplanationAED stands for Automated External Defibrillator, a device used to deliver a shock to the heart during cardiac arrest.
#4
Which artery is often used to check a person's pulse during CPR?
Carotid artery
ExplanationThe carotid artery is commonly checked for a pulse during CPR to assess circulation.
#5
What does ROSC stand for in the context of resuscitation?
Return of Spontaneous Circulation
ExplanationROSC stands for Return of Spontaneous Circulation, indicating the restoration of a heartbeat.
#6
Which of the following is a common cause of cardiac arrest in adults?
Coronary artery disease
ExplanationCardiac arrest in adults is often caused by conditions such as coronary artery disease.
#7
Which of the following is a common sign of shock in a person experiencing cardiac arrest?
Low blood pressure
ExplanationLow blood pressure is a common sign of shock in a person experiencing cardiac arrest.
#8
What is the acronym for the chain of survival in emergency cardiac care?
CPR
ExplanationCPR represents the acronym for the chain of survival in emergency cardiac care.
#9
What is the recommended depth of chest compressions for adult CPR?
At least 2 inches (5 centimeters)
ExplanationEffective adult CPR requires chest compressions of at least 2 inches (5 centimeters) in depth.
#10
Which rhythm is most commonly associated with sudden cardiac arrest?
Ventricular fibrillation
ExplanationSudden cardiac arrest is often characterized by the rhythm of ventricular fibrillation.
#11
What is the first treatment for a person experiencing ventricular fibrillation?
Defibrillation
ExplanationDefibrillation is the primary treatment to restore a normal heart rhythm in ventricular fibrillation.
#12
In CPR, what does the acronym CAB stand for?
Circulation, Airway, Breathing
ExplanationCAB in CPR stands for Circulation, Airway, Breathing, emphasizing the sequence of interventions.
#13
What is the purpose of defibrillation in cardiac arrest?
To restart the heart
ExplanationDefibrillation aims to restart the heart and restore a normal rhythm during cardiac arrest.
#14
Which organization publishes guidelines for basic and advanced cardiac life support?
American Heart Association (AHA)
ExplanationThe American Heart Association (AHA) publishes guidelines for both basic and advanced cardiac life support.

1/2 inch (1.25 centimeters)
ExplanationFor pediatric patients during CPR, the recommended compression depth is 1/2 inch (1.25 centimeters).
#16
Which rhythm is characterized by a chaotic, irregular heartbeat during cardiac arrest?
Ventricular fibrillation
ExplanationA chaotic, irregular heartbeat during cardiac arrest is often characterized by ventricular fibrillation.
#17
What is the recommended ratio of chest compressions to rescue breaths in adult CPR?
30:2
ExplanationIn adult CPR, the recommended ratio of chest compressions to rescue breaths is 30:2.
#18
What is the recommended rate of chest compressions per minute for adult CPR?
100-120
ExplanationEffective adult CPR involves chest compressions at a rate of 100-120 compressions per minute.
#19
What is the term for the ineffective quivering of the heart muscle during cardiac arrest?
Ventricular fibrillation
ExplanationThe ineffective quivering of the heart muscle during cardiac arrest is termed ventricular fibrillation.
#20
