RECOMMENDED |NEW AND REVISED
1. An adult suddenly collapses and is unresponsive. What should the rescuer do
first?
A. Obtain an ECG
B. Check responsiveness and assess breathing
C. Administer epinephrine
D. Establish IV access
Correct Answer: B
Rationale: Initial assessment begins by determining responsiveness and whether the patient is
breathing normally. If cardiac arrest is suspected, emergency response and resuscitation should
be activated immediately.
2. Which finding most strongly indicates cardiac arrest?
A. Normal breathing
B. Unresponsiveness with absent or abnormal breathing
C. Mild tachycardia
D. Hypertension
Correct Answer: B
Rationale: An unresponsive patient with absent or abnormal breathing should be treated as
being in cardiac arrest while the appropriate assessment and response occur.
3. What is the primary purpose of high-quality CPR?
A. Restore normal blood pressure immediately
B. Maintain circulation to vital organs until definitive treatment is available
,C. Eliminate all arrhythmias
D. Replace defibrillation
Correct Answer: B
Rationale: Effective CPR provides artificial circulation and oxygen delivery to the brain and
heart while the resuscitation team addresses the underlying cause.
4. Which is an essential characteristic of high-quality adult CPR?
A. Frequent prolonged pauses
B. Effective chest compressions with minimal interruptions
C. Slow compressions
D. Hyperventilation
Correct Answer: B
Rationale: High-quality CPR depends on effective compressions and minimizing interruptions.
The 2025 AHA guidelines continue to emphasize high-quality CPR as a central component of
resuscitation.
5. Where should adult chest compressions be performed?
A. Upper abdomen
B. Center of the chest on the lower half of the sternum
C. Left shoulder
D. Right upper chest
Correct Answer: B
Rationale: Proper hand placement over the lower half of the sternum allows effective cardiac
compression.
6. What is the recommended adult chest-compression rate?
A. 40–60/min
B. 60–80/min
C. 100–120/min
D. 140–160/min
,Correct Answer: C
Rationale: Adult CPR uses a compression rate of approximately 100–120 compressions per
minute.
7. What should the rescuer do after each chest compression?
A. Maintain complete recoil
B. Lean heavily on the chest
C. Stop for several seconds
D. Remove the patient from the bed
Correct Answer: A
Rationale: Complete chest recoil allows the heart to refill between compressions.
8. Why should interruptions in chest compressions be minimized?
A. Interruptions reduce effective circulation
B. Interruptions improve coronary perfusion
C. Interruptions increase oxygen delivery
D. Interruptions prevent defibrillation
Correct Answer: A
Rationale: Interruptions reduce blood flow generated by CPR and can negatively affect
resuscitation effectiveness.
9. What is the standard adult compression-to-ventilation ratio when no advanced
airway is in place?
A. 15:1
B. 30:2
C. 5:1
D. 10:2
Correct Answer: B
Rationale: Two-rescuer adult CPR without an advanced airway uses 30 compressions followed
by 2 breaths.
, 10. Excessive ventilation during CPR should be avoided because it can:
A. Improve venous return
B. Reduce venous return and potentially impair circulation
C. Eliminate ventricular fibrillation
D. Increase coronary perfusion
Correct Answer: B
Rationale: Excessive ventilation can increase intrathoracic pressure and interfere with venous
return and cardiac output.
11. What is the preferred initial vascular access approach for an adult in cardiac
arrest according to the 2025 AHA guidance?
A. IO access must always come first
B. IV access is preferred initially
C. Central venous access is mandatory
D. No vascular access is required
Correct Answer: B
Rationale: The 2025 AHA guidelines recommend attempting IV access before IO access in
adult cardiac arrest; if IV attempts are unsuccessful, IO access should be considered.
12. Which device can provide an early analysis of cardiac rhythm?
A. AED
B. Pulse oximeter only
C. Thermometer
D. Glucometer
Correct Answer: A
Rationale: An AED analyzes the cardiac rhythm and determines whether a shockable rhythm is
present.
13. When should an AED be used?
