Incorrect. For unstable narrow, irregular tachycardias, synchronized cardioversion at 120-200 J is recommended.

Incorrect. Waveform capnography ensures proper ET tube placement by continuously monitoring exhaled CO? levels.

Incorrect. Amiodarone stabilizes the myocardium and is given as a bolus for refractory VF or pulseless VT.

Incorrect. A PETCO2 reading above 10 mmHg indicates adequate chest compressions and cardiac output during CPR.

Incorrect. Oxygen saturation should be maintained at 92-96% to prevent hypoxia and avoid the harmful effects of hyperoxia.

Incorrect. Adenosine is the first-line drug for treating narrow-complex SVT by slowing conduction through the AV node.

Incorrect. Hypovolemia is a reversible cause of cardiac arrest and should be corrected with fluid resuscitation.

Incorrect. Dopamine is used when atropine is ineffective, improving heart rate and contractility by stimulating beta receptors.

Incorrect. VF is a shockable rhythm that requires immediate defibrillation to restore organized cardiac activity.

Incorrect. Providing 6-8 breaths per minute prevents hyperventilation and maintains adequate oxygenation during CPR with an advanced airway.

Incorrect. VF is a shockable rhythm, and immediate defibrillation is the most effective treatment.

Incorrect. A PETCO2 reading above 10 mmHg indicates that chest compressions are generating sufficient circulation during CPR.

Incorrect. Atropine is the first-line treatment for symptomatic bradycardia, increasing the heart rate by blocking vagal stimulation.
