Explain the elements of basic life support (BLS), how it differs from advanced life support (ALS),
and why BLS must be applied rapidly. ------- ✔ CORRECT ANSWER ✓✓Basic Life Support (BLS): is
noninvasive emergency lifesaving care that is used to treat medical conditions, including airway
obstruction, respiratory arrest, and cardiac arrest. BLS can maintain life for a short time, until
ALS measures can be started.
Focus on: Airway (Obstruction)
Breathing (Respiratory Arrest)
Circulation (Cardiac Arrest)
Advanced Life Support (ALS): involves advanced lifesaving procedures such as cardiac
monitoring, administration of intravenous (IV) fluids and medications, and the use of advanced
airway adjuncts
Explain the goals of cardiopulmonary resuscitation (CPR) and when it should be performed on a
patient. ------- ✔ CORRECT ANSWER ✓✓Steps for Cardiopulmonary Resuscitation (CPR):
1. Restore circulation by performing chest compressions to circulate blood
2. Perform 30 high-quality compressions to a depth of 2 to 2.4 inches at a rate of 100 to 120 per
minute
3. Open the airway with jaw-thrust or head tilt-chin lift maneuver
, 4. Restore breathing by providing rescue breaths (Via mouth-to-mask ventilation or bag-valve
mask)
Administer 2 breaths, each over 1 second, while visualizing for chest rise.
Explain the components of CPR, the five links in the American Heart Association (AHA) chain of
survival, and how each one relates to maximizing the survival of a patient. ------- ✔ CORRECT
ANSWER ✓✓Recognition and Activation of the Emergency Response System: Learn to recognize
early warning signs and immediately call 911
Immediate, high-quality CPR: Successful resuscitation of a person in cardiac arrest.
Rapid defibrillation: offers best opportunity to achieve a successful patient outcome
Basic and Advanced Emergency Medical Services: CPR, Basic airway management, Advanced
airway management, Manual defibrillation, Vascular access, Transcutaneous pacing
Advanced Life Support and Post Arrest Care:
Discuss guidelines for circumstances that require the use of an automated external defibrillator
(AED) on both adult and pediatric patients experiencing cardiac arrest. ------- ✔ CORRECT
ANSWER ✓✓AEDs can be safely be used on children using the pediatric-sized pads and a dose-
attenuating system (energy reducer)Apply AEDs after first five cycles of CPR has been completed
Cardiac arrest in children is usually the result of respiratory failure, therefore, oxygenation and
ventilation are vitally important
If the patient is an infant a manual defibrillator is preferred
