Incorrect. TTM helps reduce neurological injury by maintaining a core temperature of 32-36°C after the return of spontaneous circulation.

Incorrect. Synchronized cardioversion is used for unstable atrial fibrillation to restore organized electrical activity.

Incorrect. Maximum energy for monophasic defibrillators; for biphasic, follow manufacturer recommendations.

Incorrect. Early defibrillation within 30 seconds of a witnessed VF arrest increases survival rates significantly.

Incorrect. PEA is treated with CPR and epinephrine, as defibrillation is ineffective for non-shockable rhythms.

Incorrect. Rapid defibrillation within 1 minute of witnessed VF increases the likelihood of survival and ROSC.

Incorrect. Epinephrine is administered after defibrillation to enhance coronary and cerebral perfusion during resuscitation.

Incorrect. Thrombosis (pulmonary or coronary) is a reversible cause of cardiac arrest and should be addressed immediately.

Incorrect. VF is a shockable rhythm, and defibrillation is the most effective intervention to restore a normal rhythm.

Incorrect. Asystole is a non-shockable rhythm requiring immediate high-quality CPR and administration of epinephrine.

Incorrect. IO access provides a reliable alternative for rapid drug delivery during resuscitation when IV access cannot be obtained.

Incorrect. High-quality CPR should be resumed immediately after a shock to maintain perfusion and increase the likelihood of ROSC.

Incorrect. Waveform capnography provides real-time confirmation of ET tube placement and ensures proper ventilation.

Incorrect. With an advanced airway, compressions continue uninterrupted while ventilation is provided at a rate of 10 breaths per minute.

Incorrect. Delivering 10 breaths per minute ensures adequate oxygenation without causing hyperventilation.

Incorrect. Compressing the chest 2-2.4 inches ensures adequate blood flow while minimizing injury risks.

Incorrect. Atropine is given at a dose of 0.5 mg every 3-5 minutes during bradycardia, up to a maximum dose of 3 mg.

Incorrect. Compressing to one-third the depth of the chest ensures adequate perfusion while minimizing the risk of injury.

Incorrect. Amiodarone is used after defibrillation and epinephrine for refractory VF to stabilize the myocardium.

Incorrect. Magnesium sulfate stabilizes the cardiac membrane and is the drug of choice for treating torsades de pointes.

Incorrect. Vagal maneuvers stimulate the vagus nerve, often terminating reentrant arrhythmias causing narrow-complex tachycardia.

Incorrect. Stabilizes the myocardium and suppresses arrhythmias during refractory VF or pulseless VT.

Incorrect. Interruptions in chest compressions should not exceed 10 seconds to maintain adequate perfusion to vital organs.

Incorrect. Magnesium sulfate stabilizes the myocardium and is the drug of choice for torsades de pointes.

Incorrect. Adult defibrillation with a biphasic defibrillator typically starts at 120-200 J, not 360 J, depending on the manufacturer's guidelines.
