Incorrect. IM epinephrine is the first-line treatment for anaphylaxis, administered into the mid-thigh for rapid absorption.

Incorrect. Delivering 1 breath every 5-6 seconds prevents hypoventilation or hyperventilation.

Incorrect. Avoid delays to minimize interruptions in chest compressions and maintain perfusion.

Incorrect. High-quality CPR should be resumed immediately after defibrillation to maintain perfusion and increase chances of ROSC.

Incorrect. Synchronized cardioversion with 50-100 J is effective for narrow, regular tachycardias that are unstable.

Incorrect. The initial dose of adenosine for stable SVT in adults is 6 mg IV, followed by 12 mg if needed for subsequent doses.

Incorrect. Epinephrine is administered every 3-5 minutes during pediatric cardiac arrest to enhance coronary and cerebral perfusion.

Incorrect. The correct compression-to-ventilation ratio for adult CPR without an advanced airway is 30:2.

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

Incorrect. Adenosine is contraindicated in unstable patients; synchronized cardioversion is the treatment of choice in such cases.

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

Incorrect. Amiodarone is preferred, but lidocaine is an alternative antiarrhythmic for refractory VF or pulseless VT.

Incorrect. Interruptions in chest compressions should be minimized to less than 10 seconds to maintain adequate perfusion.

Incorrect. Hypothermia is a reversible cause of cardiac arrest and should be treated with warming measures.

Incorrect. Post-ROSC care focuses on optimizing oxygenation, ventilation, and hemodynamic stability to prevent further organ damage.

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

Incorrect. Atropine is the first-line drug for treating symptomatic bradycardia by increasing heart rate through vagal inhibition.

Incorrect. Adenosine is administered as a 6 mg rapid IV push, followed by a saline flush, to terminate reentrant arrhythmias.

Incorrect. ROSC signifies the resumption of spontaneous cardiac activity with effective circulation, improving patient survival.

Incorrect. Pediatric defibrillation starts at 2 J/kg and may increase to 4 J/kg for subsequent shocks if VF persists.

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

Incorrect. Naloxone blocks opioid receptors and is administered to reverse opioid overdose and restore adequate respiration.

Incorrect. PETCO2 monitoring ensures effective ventilation and provides feedback on the quality of chest compressions during CPR.

Incorrect. Adenosine 6 mg is given as a rapid IV push for terminating narrow-complex SVT caused by reentrant pathways.

Incorrect. PETCO2 values greater than 10 mmHg during CPR indicate adequate chest compressions and blood circulation.

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

Incorrect. Defibrillation is the priority for VF and should not be delayed for drug administration, as it is the definitive treatment.

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

Incorrect. Magnesium sulfate is used to treat torsades de pointes but is not the first-line drug for VF, where epinephrine is prioritized.

Incorrect. Rotating team roles every 2 minutes prevents fatigue, ensuring consistent delivery of high-quality chest compressions.

Incorrect. This rate ensures effective circulation without causing inadequate ventricular filling.

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

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

Incorrect. A 30:2 ratio ensures sufficient oxygenation and circulation in adults during CPR without an advanced airway.

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

Incorrect. PETCO2 monitoring provides continuous feedback on the quality of chest compressions and the effectiveness of resuscitation.

Incorrect. Two minutes of CPR (about 5 cycles of 30 compressions and 2 breaths) should be performed before reassessing the rhythm.

Incorrect. Compressions at 1/3 the depth of the chest ensure adequate perfusion while minimizing injury to internal organs.
