#1
Which of the following is a correct step in performing CPR on an adult?
Check for responsiveness first
ExplanationInitiating CPR by ensuring the victim is unresponsive is crucial.
#2
What is the purpose of an Automated External Defibrillator (AED) in CPR?
To analyze heart rhythm and deliver a shock if necessary
ExplanationAEDs assess heart rhythm and administer shocks if abnormalities are detected.
#3
What is the first step to take when encountering a person who has collapsed and is unresponsive?
Call emergency medical services (EMS)
ExplanationImmediate activation of EMS is vital in such emergencies to ensure timely medical assistance.
#4
Which of the following is a symptom of sudden cardiac arrest?
Loss of consciousness
ExplanationLoss of consciousness is a hallmark symptom of sudden cardiac arrest.
#5
Which of the following is a correct step in performing CPR on a child?
Use the heel of one hand for compressions
ExplanationUsing the heel of one hand is recommended for pediatric CPR to adapt to smaller chest sizes.
#6
What is the compression-to-ventilation ratio for adult CPR?
30:2
ExplanationThe recommended ratio for chest compressions to rescue breaths in adult CPR is 30 compressions to 2 breaths.
#7
In which situation should an AED be used?
When a person is unresponsive and not breathing
ExplanationAEDs are employed when individuals are both unresponsive and not breathing.
#8
What is the correct hand placement for performing chest compressions on an adult?
Center of the chest, just below the nipple line
ExplanationCorrect hand placement facilitates effective chest compressions, ensuring proper circulation.
#9
What should be done before delivering a shock with an AED?
Ensure no one is touching the person
ExplanationSafety precautions include ensuring no contact with the individual to avoid injury.
#10
What is the recommended depth for chest compressions in adult CPR?
At least 2 inches (5 centimeters)
ExplanationA compression depth of at least 2 inches ensures effective circulation during adult CPR.
#11
What is the correct placement of AED pads on the victim's chest?
One pad on the upper right chest and the other on the lower left side of the chest
ExplanationProper pad placement on the chest ensures effective delivery of electrical shocks.
#12
What is the purpose of the 'shock advised' prompt on an AED?
To prompt the rescuer to deliver a shock if indicated
ExplanationPrompting rescuers to administer a shock when necessary aids in timely intervention.
#13
What is the recommended age for using pediatric AED pads?
1 to 8 years old
ExplanationPediatric AED pads are designed for children aged 1 to 8 years to ensure proper energy delivery.
#14
What is the primary purpose of CPR in a cardiac arrest situation?
To maintain blood flow to vital organs
ExplanationCPR sustains circulation, ensuring oxygen-rich blood reaches vital organs during cardiac arrest.
#15
What does an AED analyze to determine if a shock is needed?
Heart rhythm
ExplanationAEDs analyze the victim's heart rhythm to determine whether a shock is required to restore normal cardiac activity.
