#1
Which of the following is the correct compression-to-ventilation ratio for adult CPR?
30:2
ExplanationMore compressions to ventilations ensure adequate oxygenation and blood circulation.
#2
For which of the following patients would you use the Heimlich maneuver?
A conscious adult who is choking and cannot cough, speak, or breathe
ExplanationThe maneuver helps clear airway obstructions in conscious choking victims.
#3
When performing CPR on an infant, how should you deliver chest compressions?
Use two fingers in the center of the chest just below the nipple line
ExplanationProper technique ensures effective compressions without causing harm.
#4
Which of the following is a sign of effective chest compressions?
The chest visibly returns to its normal position after compression
ExplanationVisible chest recoil indicates adequate compression depth and recoil.
#5
For a choking infant, which method is recommended to relieve the obstruction?
Back slaps and chest thrusts
ExplanationThese techniques help dislodge the foreign object blocking the infant's airway.
#6
Which of the following is NOT a component of basic life support?
Administering oral medications
ExplanationBasic life support focuses on immediate interventions without medication administration.
#7
Which of the following best describes the purpose of an Automated External Defibrillator (AED)?
To deliver an electric shock to help the heart re-establish an effective rhythm
ExplanationAEDs intervene in cardiac arrest by restoring normal heart rhythm.
#8
If an adult is choking and unable to cough, speak, or breathe, what is the first step you should take?
Call for emergency medical services
ExplanationProfessional assistance may be needed to dislodge the obstruction.
#9
What is the recommended depth of chest compressions for an adult during CPR?
At least 2 inches
ExplanationSufficient depth ensures effective blood flow and organ perfusion.
#10
What is the first step you should take when you approach a scene as a first responder?
Check the scene for safety
ExplanationEnsuring safety prevents additional harm to victims and responders.
#11
How often should you check for responsiveness and normal breathing in an unresponsive victim not breathing normally?
Every 2 minutes
ExplanationRegular checks ensure timely intervention and adjustment of CPR procedures.
#12
What is the best action to take if a victim of choking becomes unconscious?
Start CPR beginning with chest compressions
ExplanationImmediate CPR helps maintain oxygenation and circulation.
#13
What is the primary purpose of giving rescue breaths during CPR?
To provide oxygen to the lungs
ExplanationRescue breaths help maintain oxygen levels in the bloodstream.
#14
In which scenario is it appropriate to stop CPR once it has been started?
All of the above
ExplanationStopping CPR depends on advanced medical intervention or the victim's recovery.
#15
What is the main reason for rotating CPR providers every 2 minutes?
To prevent provider fatigue and ensure high-quality compressions
ExplanationRotation maintains effective CPR quality and minimizes fatigue.
#16
What is the correct action if a victim of drowning is unresponsive and not breathing normally?
Give two rescue breaths before starting chest compressions
ExplanationEnsuring oxygenation is crucial before initiating chest compressions.
#17
In the absence of a pulse, but with occasional gasping breaths, how should you proceed?
Begin CPR immediately
ExplanationCPR should be initiated promptly to maximize chances of survival.
#18
What is the first step in using an AED?
Turn on the AED
ExplanationActivation ensures readiness for defibrillation and prompts subsequent actions.
#19
When performing CPR on a child, how should the depth of chest compressions compare to that of an adult?
About one-third the depth of the chest, approximately 2 inches
ExplanationChildren require gentler compressions to avoid injury.
#20
When using an Automated External Defibrillator (AED), what is the correct sequence of actions?
Turn on the AED, attach pads, stand back and then analyze the rhythm
ExplanationFollowing the correct sequence maximizes the chance of successful defibrillation.
#21
Which of the following best describes the chain of survival for adults?
Early access, early CPR, early defibrillation, early advanced care
ExplanationThe chain outlines crucial steps for maximizing survival rates in cardiac arrest.
#22
What is the purpose of early defibrillation in the chain of survival?
To normalize the heart's rhythm
ExplanationDefibrillation promptly addresses lethal heart rhythms, restoring normal activity.
#23
How should you modify CPR for a pregnant woman?
Tilt the patient to the left to relieve pressure on the inferior vena cava
ExplanationThis position maximizes blood flow to the heart and fetus.
#24
What is the significance of the 'Look, Listen, and Feel' technique in the context of CPR?
It is an outdated method for checking responsiveness
ExplanationModern CPR emphasizes immediate chest compressions over prolonged assessment.
#25
What action should be taken if defibrillation is needed and an AED indicates a 'shock advised' message?
Ensure no one is touching the victim and press the shock button
ExplanationSafety precautions minimize risks associated with defibrillation.
