Incorrect. Provides external electrical stimuli to maintain adequate heart rate when atropine fails.

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

Incorrect. Pediatric defibrillation starts at 2 J/kg, increasing to 4 J/kg for subsequent shocks if needed.

Incorrect. Adenosine is used to terminate reentrant arrhythmias in narrow-complex SVT by slowing conduction through the AV node.

Incorrect. The target oxygen saturation is 92-96% to avoid hyperoxia, which can contribute to oxidative injury.

Incorrect. Pulseless VT is treated with defibrillation, not atropine. Atropine is used for symptomatic bradycardia.

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

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

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

Incorrect. The compression fraction should be greater than 80% to maximize perfusion during CPR.

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

Incorrect. Maintaining this range prevents hypoxia while minimizing the risks of hyperoxia and oxidative injury.

Incorrect. The maximum dose of atropine for bradycardia is 3 mg, with doses given at 0.5 mg intervals every 3-5 minutes.

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

Incorrect. While hypoglycemia can cause critical symptoms, it is not included in the H's and T's of reversible causes of cardiac arrest.

Incorrect. The two-thumb encircling technique provides high-quality compressions for infants during CPR.

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

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

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

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

Incorrect. Early defibrillation is critical for survival, especially in shockable rhythms like VF/VT.

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

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

Incorrect. Oxygen saturation should be maintained at 92-96% to avoid hypoxia and reduce the risk of hyperoxia and oxidative stress.

Incorrect. Rhythm checks are performed every 2 minutes to evaluate for shockable rhythms and assess the need for defibrillation.

Incorrect. Delivering 6-8 breaths per minute minimizes interruptions in chest compressions and prevents hyperventilation.

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

Incorrect. A single rescuer performs 30 compressions followed by 2 breaths to maximize perfusion and oxygenation in pediatric CPR.

Incorrect. Calcium gluconate stabilizes the cardiac membrane and reduces the risk of life-threatening arrhythmias caused by hyperkalemia.

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

Incorrect. A supine position ensures proper electrode placement and effective delivery of defibrillation shocks.

Incorrect. Pulse checks should be limited to 5-10 seconds to minimize interruptions in chest compressions.

Incorrect. Optimal for maintaining adequate circulation without risking poor perfusion due to excessive speed.

Incorrect. Atropine should not exceed a total dose of 3 mg when treating symptomatic bradycardia in adults.

Incorrect. Maintaining oxygen saturation within this range ensures adequate oxygenation without the risk of hyperoxia.

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

Incorrect. Rhythm checks should be performed every 2 minutes during CPR, coinciding with compressor role switches.

Incorrect. Synchronized cardioversion is indicated for unstable atrial fibrillation to restore sinus rhythm and prevent hemodynamic collapse.

Incorrect. Asystole is a non-shockable rhythm treated with high-quality CPR and epinephrine.

Incorrect. With an advanced airway in place, uninterrupted compressions improve blood flow while ventilation is delivered separately.

Incorrect. Indicates effective chest compressions and blood circulation during resuscitation.

Incorrect. Minimizes interruptions to maintain blood flow to vital organs.

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