Title: Advanced Cardiovascular Life Support and Emergency Response:
A Comprehensive 150-Question Examination for Healthcare
Professionals Based on 2025 AHA Guidelines – Version 2.0
,Instructions
This examination consists of 150 multiple-choice questions designed to assess advanced knowledge of
cardiopulmonary resuscitation (CPR), emergency response protocols, and advanced cardiovascular life
support (ACLS) for healthcare professionals. Each question has one correct answer. Select the best
answer for each question. Questions cover basic life support (BLS), advanced cardiovascular life
support (ACLS), pediatric and neonatal resuscitation, emergency response systems, and special
circumstances based on the 2025 American Heart Association Guidelines for Cardiopulmonary
Resuscitation and Emergency Cardiovascular Care.
Section 1: Basic Life Support – Adult (Questions 1–25)
1. A nurse enters a patient's room and finds the patient unresponsive on the floor. After
confirmingunresponsiveness and calling for help, what is the nurse's immediate next action
in the C-A-B sequence?
A. Open the airway using head-tilt, chin-lift
B. Check for a carotid pulse for 5-10 seconds
C. Begin chest compressions at the center of the chest
D. Provide two rescue breaths
- detailed answer 100 % correct :-C
Rationale: The C-A-B sequence prioritizes chest compressions over airway and breathing. After
confirming unresponsiveness and activating the emergency response system, the nurse should
immediately begin chest compressions at the center of the chest. Compressions are the most critical
intervention in cardiac arrest and should not be delayed for pulse checks or airway management.
2. An adult patient in cardiac arrest is receiving CPR. The monitor shows a shockable rhythm.
Thedefibrillator is charging. What should the compressor do during defibrillator charging?
, A. Continue compressions until the defibrillator is fully charged and the operator signals to clear
B. Stop compressions immediately to allow the defibrillator to charge
C. Continue compressions at a slower rate during charging
D. Stop compressions and check for a pulse
- detailed answer 100 % correct :-A
Rationale: Chest compressions should continue while the defibrillator is charging to maintain coronary
perfusion pressure. Compressions should only be stopped when the defibrillator is fully charged and
the operator signals "clear" to deliver the shock. This minimizes interruptions in CPR.
3. A nurse is performing CPR on an adult patient. The patient's ETCO2 reading is 12 mmHg.
Whatdoes this indicate?
A. The patient has achieved ROSC
B. The quality of chest compressions is inadequate
C. The patient is developing acidosis
D. The patient is hyperventilating
- detailed answer 100 % correct :-B
Rationale: An ETCO2 reading of less than 10-15 mmHg during CPR indicates inadequate cardiac
output and poor-quality chest compressions. The nurse should reassess compression depth, rate, and
technique to improve perfusion. ETCO2 monitoring provides real-time feedback on CPR effectiveness.
4. What is the maximum recommended time for interrupting chest compressions to deliver
tworescue breaths during adult CPR?
A. 5 seconds
B. 10 seconds
C. 15 seconds
D. 20 seconds
- detailed answer 100 % correct :-B
, Rationale: Interruptions in chest compressions should be minimized, with pauses limited to less than
10 seconds. This includes pauses for ventilations. Prolonged interruptions decrease coronary perfusion
pressure and reduce the likelihood of ROSC.
5. An adult patient is in cardiac arrest with a shockable rhythm. The nurse delivers a shock and
therhythm check reveals asystole. What is the appropriate next action?
A. Defibrillate immediately again
B. Resume CPR and administer epinephrine
C. Check for a pulse
D. Administer amiodarone
- detailed answer 100 % correct :-B
Rationale: Asystole is a non-shockable rhythm. The nurse should resume CPR immediately and
administer epinephrine. Defibrillation is not indicated for asystole. The priority is high-quality CPR and
identifying/treating reversible causes.
6. A nurse is providing CPR to an adult patient. The patient is intubated with an advanced
airway inplace. How should the nurse coordinate compressions and ventilations?
A. Provide continuous compressions at 100-120/min with 1 breath every 6 seconds
B. Provide 30 compressions followed by 2 ventilations
C. Provide 15 compressions followed by 2 ventilations
D. Provide continuous compressions at 100-120/min with 2 breaths every 30 compressions
- detailed answer 100 % correct :-A
Rationale: When an advanced airway is in place, ventilations should be delivered at a rate of 1 breath
every 6 seconds (10 breaths per minute) without pausing chest compressions. This allows for
continuous compressions at 100-120 per minute, maximizing perfusion.
