1. What is the primary goal of high-quality CPR during cardiac
arrest?
A. Increase blood pressure to normal immediately
B. Maintain circulation to vital organs until ROSC or definitive
intervention
C. Prevent all rib fractures
D. Restore consciousness within 1 minute
Answer: B. Maintain circulation to vital organs until ROSC or
definitive intervention
Rationale: High-quality CPR provides critical blood flow to the
brain and heart while reversible causes are addressed.
2. Which cardiac rhythms are considered shockable in adult
cardiac arrest?
A. Asystole and PEA
B. Sinus bradycardia and PEA
C. Ventricular fibrillation and pulseless ventricular tachycardia
D. Atrial fibrillation and atrial flutter
Answer: C. Ventricular fibrillation and pulseless ventricular
tachycardia
,Rationale: VF and pulseless VT are treated with immediate
defibrillation plus CPR.
3. Which rhythms are classified as nonshockable?
A. VF and pulseless VT
B. Asystole and pulseless electrical activity
C. VT and SVT
D. VF and atrial fibrillation
Answer: B. Asystole and pulseless electrical activity
Rationale: Nonshockable arrest rhythms are managed primarily
with high-quality CPR, epinephrine, and treatment of reversible
causes.
4. What should be done immediately when an adult is found
unresponsive and not breathing normally?
A. Obtain a 12-lead ECG first
B. Begin appropriate resuscitation actions and activate the
emergency response system
C. Give atropine
D. Administer oxygen for 10 minutes before CPR
Answer: B. Begin appropriate resuscitation actions and
activate the emergency response system
Rationale: Early recognition, emergency activation, and
,immediate CPR are fundamental components of the chain of
survival.
5. Which finding most strongly indicates cardiac arrest?
A. Slow pulse with normal consciousness
B. Unresponsiveness with absent or abnormal breathing and no
definite pulse
C. Blood pressure of 100/60 mmHg
D. Respiratory rate of 20/min
Answer: B. Unresponsiveness with absent or abnormal
breathing and no definite pulse
Rationale: Cardiac arrest should be recognized rapidly and
treated without unnecessary delays.
6. What is the recommended adult chest-compression rate
during CPR?
A. 60–80/min
B. 80–90/min
C. 100–120/min
D. 140–160/min
Answer: C. 100–120/min
Rationale: A compression rate of 100–120/min helps optimize
coronary and cerebral perfusion.
, 7. What is the recommended adult chest-compression depth
during CPR?
A. At least 1 cm
B. At least 2 cm
C. At least 5 cm while avoiding excessive depth
D. Exactly 8 cm
Answer: C. At least 5 cm while avoiding excessive depth
Rationale: Adequate depth is necessary to generate effective
blood flow while excessive compression depth can increase
injury.
8. Which action helps minimize interruptions in chest
compressions?
A. Performing frequent pulse checks
B. Limiting pauses for rhythm analysis and defibrillation
C. Stopping CPR whenever an IV is inserted
D. Ventilating continuously without compressions
Answer: B. Limiting pauses for rhythm analysis and
defibrillation
Rationale: Minimizing interruptions helps preserve coronary
and cerebral perfusion.
9. During two-rescuer adult CPR without an advanced airway,
what compression-to-ventilation ratio is generally used?
