, Q1. During a cardiac arrest resuscitation, a patient is in pulseless electrical activity (PEA). The team leader
suspects a reversible cause. Which of the following diagnostic findings, if present, would most directly
indicate a specific reversible cause that requires immediate, targeted intervention before standard ACLS
algorithm continuation?
A. End-tidal CO2 (ETCO2) of 15 mmHg with adequate chest compressions
B. Pulse oximetry reading of 88% on 100% oxygen
C. Arterial blood gas showing pH 7.25 and pCO2 50 mmHg
D. Point-of-care ultrasound revealing a hyperdynamic left ventricle with a small pericardial effusion
Correct Answer: D. Point-of-care ultrasound revealing a hyperdynamic left ventricle with a small pericardial
effusion
Rationale: A hyperdynamic left ventricle with a small pericardial effusion suggests cardiac tamponade, a
reversible cause of PEA. Immediate pericardiocentesis is indicated. ETCO2 <10 mmHg suggests low cardiac
output but is not specific to a reversible cause. Pulse oximetry is unreliable during arrest. ABG findings are
nonspecific.
Why Wrong:
A - Low ETCO2 indicates poor perfusion but does not identify a specific reversible cause requiring
immediate intervention.
B - Pulse oximetry is unreliable during cardiac arrest due to poor peripheral perfusion and does not indicate a
specific reversible cause.
C - ABG findings of mild acidosis and hypercapnia are common during arrest and not specific to a reversible
cause.

T's)
Q2. A patient with a known history of severe left ventricular systolic dysfunction (LVEF 25%) presents with
sustained monomorphic ventricular tachycardia (VT) at a rate of 180/min, blood pressure 80/40 mmHg, and
mild confusion. The patient has a dual-chamber pacemaker in situ. After ensuring proper pad placement,
synchronized cardioversion is attempted but fails to convert the rhythm. What is the most appropriate next
step in management?
A. Administer amiodarone 150 mg IV over 10 minutes, then repeat cardioversion
B. Administer lidocaine 1.5 mg/kg IV push, then repeat cardioversion
C. Increase shock energy to maximum (360 J biphasic) and perform unsynchronized cardioversion
(defibrillation)
D. Administer adenosine 6 mg rapid IV push and repeat cardioversion
Correct Answer: C. Increase shock energy to maximum (360 J biphasic) and perform unsynchronized
cardioversion (defibrillation)
Rationale: If synchronized cardioversion fails to convert VT, and the patient is unstable, the next step is to deliver
an unsynchronized shock (defibrillation) at the highest energy setting, as synchronization may fail due to poor
R-wave detection. Amiodarone or lidocaine may be considered after shock failure, but immediate defibrillation
takes priority. Adenosine is ineffective for VT.
Why Wrong:
A - Amiodarone is appropriate for stable VT but the patient is unstable; defibrillation should precede drug
therapy.
B - Lidocaine is a second-line agent and should not delay defibrillation in unstable VT.
D - Adenosine is only effective for supraventricular tachycardias, not ventricular tachycardia.
