Cardiopulmonary Resuscitation
ExplanationEmergency procedure to maintain blood circulation and oxygenation during cardiac arrest.
#2
When performing CPR, what is the correct compression-to-ventilation ratio for adults?
30:2
Explanation30 compressions followed by 2 ventilations to maintain oxygenation and blood flow.
#3
What is the first step in the CPR sequence for an unresponsive adult?
Check for responsiveness

Lower half of the sternum
ExplanationApply pressure to the lower sternum to effectively pump blood.
#5
What is the recommended depth for chest compressions during CPR for adults?
At least 2 inches (5 centimeters)
ExplanationEnsure sufficient compression depth to adequately circulate blood.
#6
When should an AED (Automated External Defibrillator) be used during CPR?
Immediately after starting chest compressions
ExplanationTo analyze heart rhythm and deliver shocks if necessary to restore normal rhythm.
#7
What is the purpose of CPR in the event of cardiac arrest?
To improve blood circulation
ExplanationRestore blood flow to vital organs to prevent brain damage.
#8
Which of the following is a potential complication of CPR?
Rib fractures
ExplanationCommon side effect due to chest compressions but necessary for effective CPR.
#9
What is the recommended rate for chest compressions during CPR?
100-120 compressions per minute
ExplanationMaintain a steady rhythm to ensure adequate blood flow.
#10
Which of the following is a common cause of cardiac arrest in adults?
Heart attack
ExplanationSudden cessation of heart function due to cardiovascular issues.
#11
How should rescuers perform chest compressions on a pregnant woman during CPR?
Place hands higher on the sternum
ExplanationTo avoid compression of the uterus, compress slightly higher on the sternum.
