EXAM STUDY GUIDE COMPLETE
QUESTIONS AND SOLUTIONS
●● What is the main goal of BLS?
Answer: To maximize the chance of successful resuscitation based on
available scientific evidence.
●● What does BLS stand for?
Answer: Basic Life Support.
●● What are the primary medical conditions treated by BLS?
Answer: Airway obstruction, respiratory arrest, and cardiac arrest.
●● What does the acronym ABC stand for in BLS?
Answer: Airway, Breathing, Circulation.
●● What sequence is used in cardiac arrest situations?
Answer: CAB sequence (Compressions, Airway, Breathing).
●● How quickly should treatment begin after recognizing a need for
BLS?
, Answer: Within seconds.
●● What is the risk of brain damage if oxygen is cut off for more than
how many minutes?
Answer: More than 4 to 6 minutes.
●● What is the purpose of cardiopulmonary resuscitation (CPR)?
Answer: To reestablish circulation and artificial ventilation in a patient
who is not breathing and has no pulse.
●● What is the first step in performing CPR?
Answer: Restore circulation by performing high-quality chest
compressions.
●● What differentiates BLS from advanced life support (ALS)?
Answer: BLS is noninvasive and does not involve advanced procedures
like cardiac monitoring or IV medications.

Association?
Answer: Recognition of emergency response, immediate CPR, rapid
defibrillation, emergency medical services, ALS, and recovery.
