Basic Life Support (BLS) and Emergency Response Quiz

#1

What is the first step in basic life support (BLS) for an unresponsive adult?

Check for responsiveness
Explanation

Ensure the victim is unresponsive before proceeding.

#2

Which of the following is the recommended compression rate for adult CPR?

100-120 compressions per minute
Explanation

Maintain consistent compressions within this range for effectiveness.

#3

What is the acronym for the steps of basic life support (BLS)?

CAB
Explanation

Circulation, Airway, Breathing - in that order of priority.

#4

Which of the following is a common cause of sudden cardiac arrest in adults?

Heart attack
Explanation

A heart attack can lead to sudden cardiac arrest due to heart malfunction.

#5

What is the recommended compression rate for pediatric CPR?

100-120 compressions per minute
Explanation

Similar to adult CPR, maintain compressions within this range for children.

#6

Which of the following is a key aspect of delivering effective chest compressions during CPR?

Compression depth of at least 3 inches (7.5 cm)
Explanation

Adequate depth ensures sufficient blood flow.

#7

What does the acronym 'ABC' stand for in basic life support (BLS)?

Airway, Breathing, Circulation
Explanation

Sequential steps for life-saving interventions.

#8

When should you activate emergency medical services (EMS) during a cardiac arrest scenario?

Immediately upon recognizing cardiac arrest
Explanation

Prompt activation ensures timely professional intervention.

#9

What is the correct sequence of steps in the chain of survival for cardiac arrest?

Early recognition, early access to EMS, early advanced life support, early defibrillation, post-cardiac care
Explanation

Each step plays a critical role in increasing survival rates.

#10

What is the correct compression-to-ventilation ratio for CPR in newborns?

30 compressions to 2 breaths
Explanation

Similar to adults, maintain this ratio for effective resuscitation in newborns.

#11

During CPR, how should you position your hands for chest compressions on an adult?

Place the heel of one hand on the center of the chest
Explanation

This ensures effective compression on the sternum.

#12

What is the recommended compression depth for adult CPR?

At least 2 inches (5 cm)
Explanation

Adequate compression depth ensures proper blood circulation.

#13

What is the ratio of compressions to breaths in CPR for adult victims?

30 compressions to 2 breaths
Explanation

This ratio optimizes oxygenation and circulation.

#14

When should you stop CPR during an emergency situation?

When the emergency medical services (EMS) arrive
Explanation

Professional help ensures continuity of care.

#15

What is the correct hand placement for performing chest compressions on an infant during CPR?

Two fingers on the lower half of the sternum
Explanation

Infants require gentler compression using fingers.

#16

What is the ratio of compressions to breaths in CPR for infants and children?

15 compressions to 2 breaths
Explanation

Adjusted ratio for pediatric victims to ensure effective resuscitation.

#17

What is the recommended compression depth for pediatric CPR?

At least 0.5 inch (1.3 cm)
Explanation

Children require gentler compressions compared to adults.

#18

Which of the following is a step in the initial assessment of a victim in need of basic life support (BLS)?

Check for responsiveness
Explanation

Assessing responsiveness is the first step in determining necessary interventions.

#19

During CPR for adults, where should you place the heel of your hand for chest compressions?

Lower half of the sternum
Explanation

Positioning ensures effective compression on the sternum.

#20

What is the recommended compression rate for neonatal CPR?

140-160 compressions per minute
Explanation

Higher rate due to the needs of newborns for effective circulation.

#21

In basic life support (BLS), what is the purpose of the recovery position?

All of the above
Explanation

It facilitates clearing the airway and ensures breathing.

#22

Which of the following actions is NOT recommended during CPR for an adult victim?

Interrupting CPR to check for breathing
Explanation

Continuous compressions are crucial for circulation.

#23

What is the primary goal of automated external defibrillators (AEDs) in cardiac arrest emergencies?

To restart the heart
Explanation

AEDs deliver a shock to restore normal heart rhythm.

#24

What should you do if you suspect a person is experiencing a heart attack?

Call emergency medical services (EMS) immediately
Explanation

Early intervention is crucial for better outcomes in heart attacks.

#25

Which of the following actions should you take first when responding to an unconscious choking victim?

Open the airway and check for breathing
Explanation

Clearing the airway takes precedence to ensure breathing.
