Incorrect. Switching every 2 minutes reduces rescuer fatigue and ensures high-quality chest compressions.

Incorrect. For biphasic defibrillators, 120-200 J is the recommended energy range for VF.

Incorrect. PETCO2 >10 mmHg during CPR indicates effective chest compressions generating sufficient circulation.

Incorrect. Shouting for help ensures additional resources and a defibrillator are quickly available.

Incorrect. Prompt defibrillation within 30 seconds of witnessed VF arrest improves the chance of restoring a perfusing rhythm.

Incorrect. Calling for help ensures timely assistance and access to advanced resuscitation equipment.

Incorrect. Adenosine is used for narrow-complex SVT, not wide-complex tachycardia, which is typically treated with amiodarone.

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

Incorrect. Pulse checks during CPR should not exceed 10 seconds to minimize interruptions in chest compressions.

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

Incorrect. Positioning the patient with a slight left tilt prevents aortocaval compression and improves venous return during CPR.

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

Incorrect. TTM prevents further neurological injury by maintaining a controlled core temperature after ROSC.

Incorrect. A compression fraction >80% is required to maximize perfusion and improve survival rates during high-quality CPR.

Incorrect. Adenosine is administered as a rapid IV push at an initial dose of 6 mg to terminate stable SVT.

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. Oxygen levels should be monitored and optimized to maintain saturation within the target range of 92-96%.

Incorrect. Defibrillation is the primary treatment for pulseless VT, aiming to restore organized cardiac activity.

Incorrect. Hypothermia is a reversible cause of cardiac arrest and is treated by warming the patient to improve outcomes.
