#1
What does BLS stand for in medical terms?
Basic Life Support
ExplanationBLS stands for Basic Life Support, encompassing essential emergency medical interventions to sustain life.
#2
Which of the following is a primary goal of Basic Life Support (BLS)?
Restoring and maintaining circulation
ExplanationThe primary goal of BLS is to restore and maintain circulation, ensuring vital blood flow during emergencies.
#3
What is the purpose of the 'head-tilt, chin-lift' maneuver in BLS?
To open the airway
ExplanationThe 'head-tilt, chin-lift' maneuver in BLS is performed to open the airway, facilitating effective breathing in emergency situations.
#4
What action should be taken first when encountering an unresponsive victim?
Activate emergency medical services (EMS)
ExplanationThe first action when encountering an unresponsive victim is to activate emergency medical services (EMS) to initiate professional assistance.
#5
What is the purpose of the 'look, listen, and feel' approach in BLS?
To assess for signs of life
ExplanationThe 'look, listen, and feel' approach in BLS is used to systematically assess for signs of life, guiding the initiation of appropriate interventions.
#6
In the context of BLS, what does 'C-A-B' stand for?
Circulation, Airway, Breathing
Explanation'C-A-B' in BLS refers to the sequence of actions: Circulation first, followed by Airway and Breathing, prioritizing life-sustaining measures.
#7
During BLS, how should chest compressions be performed on an adult victim?
At least 3 inches deep and at a rate of 120 compressions per minute
ExplanationChest compressions on an adult during BLS should be at least 3 inches deep and delivered at a rate of 120 compressions per minute to optimize blood circulation.
#8
In BLS, what is the recommended compression-to-ventilation ratio for a single rescuer on an adult victim?
30:2
ExplanationFor a single rescuer in BLS on an adult victim, the recommended compression-to-ventilation ratio is 30 compressions followed by 2 ventilations.
#9
During BLS, what is the primary purpose of rescue breaths?
To provide oxygen to the lungs
ExplanationRescue breaths in BLS primarily aim to provide oxygen to the lungs, supporting oxygenation in cases of respiratory distress.
#10
In BLS, what is the recommended depth for chest compressions on an infant victim?
At least 1 inch
ExplanationWhen performing chest compressions on an infant during BLS, the recommended depth is at least 1 inch to ensure effective circulation.
#11
What is the purpose of the AED (Automated External Defibrillator) in BLS?
To analyze and deliver an electric shock to the heart
ExplanationThe AED in BLS serves to analyze heart rhythms and deliver an electric shock to restore normal heart activity, crucial in cardiac emergencies.
#12
What does the term 'chain of survival' refer to in BLS?
The continuum of care to improve outcomes in cardiac emergencies
ExplanationThe 'chain of survival' in BLS represents the coordinated continuum of care to enhance outcomes in cardiac emergencies, emphasizing timely and effective interventions.
#13
What is the primary purpose of the BLS team dynamics during a cardiac arrest scenario?
To coordinate and optimize resuscitation efforts
ExplanationBLS team dynamics during a cardiac arrest scenario aim to coordinate and optimize resuscitation efforts, enhancing the chances of successful outcomes.
#14
In BLS, what is the purpose of providing high-quality chest compressions?
To maintain blood flow to vital organs
ExplanationProviding high-quality chest compressions in BLS is essential to maintain consistent blood flow to vital organs, improving the chances of successful resuscitation.
#15
What is the purpose of the BLS algorithm?
To provide a step-by-step guide for the sequence of actions during resuscitation
ExplanationThe BLS algorithm serves as a step-by-step guide in resuscitation efforts, outlining the sequence of actions to optimize the chances of successful intervention.
