#1
What does the acronym BLS stand for in the context of emergency care?
Basic Life Support
ExplanationBasic life-saving techniques administered to victims of life-threatening injuries or illnesses.
#2
Which of the following is a primary component of the Chain of Survival?
Basic Life Support (BLS)
ExplanationCritical initial care provided to sustain life until advanced medical help arrives.
#3
What is the purpose of the recovery position in first aid?
To maintain an open airway
ExplanationEnsuring a clear passage for breathing while protecting the individual's spine.
#4
Which organization provides guidelines for Basic Life Support (BLS) and emergency resuscitation?
American Heart Association
ExplanationLeading authority offering standardized protocols for life-saving interventions.
#5
During CPR, what is the recommended compression depth for an adult victim?
At least 2 inches (5 centimeters)
ExplanationSufficient depth to effectively pump blood and restore circulation.
#6
What is the purpose of defibrillation in emergency resuscitation?
To restore normal heart rhythm
ExplanationResetting the heart's electrical activity to enable it to pump effectively.
#7
What is the recommended ratio of chest compressions to rescue breaths during CPR for adults?
30 compressions to 2 breaths
ExplanationOptimal balance to maintain oxygenation and circulation.
#8
Which of the following actions should be performed first in the event of witnessing a cardiac arrest?
Activate emergency medical services (EMS)
ExplanationPromptly alerting professional medical assistance to the emergency.
#9
What is the recommended compression rate for high-quality CPR?
100-120 compressions per minute
ExplanationOptimal rate to effectively circulate blood and maintain oxygenation.
#10
Which of the following is a common cause of cardiac arrest in children?
Drowning
ExplanationSubmersion leading to oxygen deprivation and subsequent cardiac failure.
#11
What is the recommended depth of compression for pediatric CPR?
At least 1.5 inches (4 centimeters)
ExplanationSufficient depth to effectively pump blood in pediatric patients.
#12
Which rhythm is considered shockable in cardiac arrest?
Ventricular Fibrillation (VF)
ExplanationAbnormal heart rhythm that can be corrected with defibrillation.
#13
Which of the following is NOT a characteristic of effective chest compressions during CPR?
Shallow depth
ExplanationInadequate compression depth leading to insufficient circulation.
#14
Which of the following is a potential complication of CPR?
Rib fractures
ExplanationInjury resulting from the force of chest compressions.
