BASIC LIFE SUPPORT EXAMS A AND B
2026 LATEST UPDATE REAL EXAM
QUESTIONS AND ANSWERS GRADED A+
⩥ When were the principles of BLS first introduced?
Answer: In 1960
⩥ What organization conducted the most recent review of BLS
techniques in 2020?
Answer: International Liaison Committee on Resuscitation (ILCOR)
⩥ What are the three main medical conditions treated by BLS?
Answer: Airway obstruction, respiratory arrest, cardiac arrest
⩥ What does the acronym ABC stand for in BLS?
Answer: Airway, Breathing, Circulation
⩥ How quickly should BLS treatment begin after recognizing a patient
needs it?
Answer: Ideally within seconds
,⩥ What is the maximum time the brain can be without oxygen before
permanent damage occurs?
Answer: 4 to 6 minutes
⩥ What is the primary purpose of cardiopulmonary resuscitation (CPR)?
Answer: To reestablish circulation and provide artificial ventilation
⩥ What are the first two steps in performing CPR?
Answer: Restore circulation (chest compressions) and open the airway
⩥ What is the difference between BLS and advanced life support
(ALS)?
Answer: BLS is noninvasive care; ALS includes cardiac monitoring, IV
fluids, and advanced airway adjuncts
⩥ What is the first step in assessing the need for BLS?
Answer: Survey the scene and complete a primary assessment
⩥ How long should it take to determine unresponsiveness in a patient?
Answer: Less than 10 seconds
⩥ What is the role of an Automated External Defibrillator (AED) in
CPR?
,Answer: To deliver an electric shock to restore normal heart rhythm in
cardiac arrest patients
⩥ When should an AED be applied to a patient?
Answer: As soon as it is available after cardiac arrest is witnessed
⩥ What should be done if a child is in cardiac arrest?
Answer: Apply the AED after the first five cycles of CPR using
pediatric-sized pads if available
⩥ What is the correct positioning for a patient during CPR?
Answer: The patient must be supine on a firm, flat surface
⩥ What is the technique for checking for breathing and a pulse?
Answer: Visualize the chest for breathing and palpate for a carotid pulse
⩥ What should be avoided during chest compressions?
Answer: Leaning on the chest between compressions
⩥ What is the head tilt-chin lift maneuver used for?
Answer: To open the airway in an unresponsive patient
, ⩥ What is the recovery position used for?
Answer: To maintain an open airway in an adequately breathing patient
with decreased consciousness
⩥ What device should be used for artificial ventilation?
Answer: A barrier device or bag-mask device
⩥ What can occur if artificial ventilation is not performed correctly?
Answer: Gastric distention
⩥ What is the importance of allowing the chest to completely recoil
during CPR?
Answer: It ensures proper blood circulation between compressions
⩥ What is the recommended compression to ventilation ratio for adults
during CPR?
Answer: 30 compressions to 2 breaths
⩥ What should be done if a patient has a stoma?
Answer: Place a bag-mask device directly over the stoma for ventilation
⩥ What is the significance of the 'chain of survival' in CPR?
