Question 1: You find an unresponsive male lying on the floor gasping for air (agonal
breaths). After activating the emergency response team, what step should you take
next?
A. Begin rescue breathing only
B. Simultaneously check for a pulse and breathing for no more than 10 seconds
C. Deliver 2 fast rescue breaths
D. Obtain an immediate 12-lead ECG
, 🟢 Correct Answer: B
Explanation: Agonal gasps do not count as normal breathing. You must check for a
carotid pulse and chest rise simultaneously for 5 to 10 seconds before starting chest
compressions.
Question 2: During CPR with no advanced airway in place, what is the correct
compression-to-ventilation ratio for an adult patient?
A. 15:2
B. 5:1
C. 30:2
D. Continuous compressions with 10 breaths per minute
🟢 Correct Answer: C
Explanation: For all adult cardiac arrest scenarios without an advanced airway, the
universal ratio is 30 chest compressions followed by 2 rescue breaths.
Question 3: To properly ventilate an adult patient in respiratory arrest who has a
perfusing pulse, how often should you deliver rescue breaths?
A. Once every 3 seconds
B. Once every 6 seconds
C. Once every 10 seconds
D. Twice every 5 seconds
🟢 Correct Answer: B
Explanation: Current guidelines recommend delivering 1 breath every 6 seconds (10
breaths per minute) for an adult with a pulse to avoid hyperventilation.

Question 4: A patient remains in ventricular fibrillation (V-Fib) despite receiving 1 shock
and 2 minutes of continuous high-quality CPR. An IV line is established. What is your
next priority intervention?
A. Administer Amiodarone 300 mg IV push
, B. Administer Epinephrine 1 mg IV push
C. Deliver a synchronized cardioversion shock
D. Inject Atropine 0.5 mg IV push
🟢 Correct Answer: B
Explanation: In the shockable arrest algorithm (V-Fib/Pulseless VT), Epinephrine 1 mg
is given after the second shock and then every 3 to 5 minutes. Amiodarone is given
later, after the third shock.
Question 5: You have completed 2 minutes of CPR on a cardiac arrest patient. During
a pause, the monitor shows asystole, and the patient has no pulse. What is the
immediate next action?
A. Terminate all resuscitative efforts
B. Charge the defibrillator and deliver a 200J shock
C. Resume chest compressions immediately
D. Prepare a dopamine infusion
🟢 Correct Answer: C
Explanation: Asystole is a non-shockable rhythm. Delivering a shock is harmful. You
must immediately resume chest compressions to maintain coronary perfusion. [1, 2]
Question 6: Which action is recommended to optimize high-quality CPR and minimize
interruptions in chest compressions during a rhythm check?
A. Stop CPR immediately when the AED arrives
B. Continue CPR while the defibrillator charges
C. Only perform pulse checks every 30 seconds
D. Check the pulse after every advanced airway breath
🟢 Correct Answer: B
Explanation: To keep the chest compression fraction as high as possible, providers
should continue compressions while the defibrillator is actively charging.
