#1
What does the acronym BLS stand for in the context of medical procedures?
Basic Life Support
ExplanationEssential emergency care to sustain life.
#2
Which of the following is a primary objective of Basic Life Support (BLS)?
Restoring and maintaining airway, breathing, and circulation
ExplanationEnsuring vital functions are sustained.
#3
In BLS, what is the recommended compression depth for adults during CPR?
2 inches (5 cm)
ExplanationEffective compression depth for cardiac support.
#4
What is the recommended compression rate for adult CPR in Basic Life Support (BLS)?
120 compressions per minute
ExplanationOptimal rate for effective cardiac support.
#5
In BLS, how should rescuers position their hands during chest compressions for adults?
One hand on top of the other, interlocked, over the center of the chest
ExplanationEnsures proper force distribution and efficacy.
#6
What is the ratio of chest compressions to rescue breaths in adult BLS?
30:2
ExplanationBalances oxygenation and circulation.
#7
Which of the following is a common early sign of cardiac arrest?
Chest pain
ExplanationOften precedes cardiac arrest.
#8

Early access to emergency care
ExplanationCritical for maximizing survival chances.
#9
What is the purpose of the recovery position in BLS?
To maintain an open airway in unconscious non-breathing individuals
ExplanationFacilitates breathing while ensuring safety.
#10
What is the purpose of the automated external defibrillator (AED) in BLS?
To analyze and deliver an electric shock to restore a normal heart rhythm
ExplanationCorrects life-threatening heart rhythms.
#11
Which of the following is a key component of the BLS sequence for adult cardiac arrest?
Starting chest compressions before checking for responsiveness
ExplanationMaximizes early intervention and survival.
#12
In BLS, what is the recommended compression depth for infants during CPR?
0.5 inches (1.25 cm)
ExplanationAppropriate for infant chest wall.
#13
Which of the following actions is NOT part of the BLS algorithm for pediatric cardiac arrest?
Checking for a pulse before starting CPR
ExplanationImmediate initiation of CPR for pediatric arrest.
