Incorrect. Hypothermia is a potentially reversible cause of cardiac arrest and should be addressed during resuscitation.

Incorrect. Assessing responsiveness is the first step in determining the need for CPR or other interventions in the BLS survey.

Incorrect. The compression-to-ventilation ratio for single-rescuer infant CPR is 30:2, ensuring sufficient oxygenation and circulation.

Incorrect. Naloxone is only used in cases of suspected opioid overdose and is not universally administered in cardiac arrest.

Incorrect. Naloxone is used to reverse opioid overdose, restoring respiratory effort in patients with respiratory depression.

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

Incorrect. Amiodarone 300 mg IV/IO is administered after defibrillation and epinephrine to treat refractory VF or pulseless VT.

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

Incorrect. If VF persists after defibrillation and epinephrine, amiodarone is administered to stabilize the rhythm.

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

Incorrect. A compression fraction above 80% ensures that most of the resuscitation time is spent performing chest compressions.

Incorrect. Minimizing interruptions to less than 10 seconds preserves perfusion and improves resuscitation outcomes.

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

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

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

Incorrect. Asystole is not a shockable rhythm; it is treated with high-quality CPR and epinephrine.

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

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

Incorrect. Amiodarone is used to stabilize wide-complex tachycardias in stable patients to prevent deterioration into cardiac arrest.

Incorrect. Early stabilization of blood pressure and oxygenation is critical to preventing further cardiac arrest after ROSC.

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

Incorrect. Epinephrine at 0.01 mg/kg IV/IO is administered every 3-5 minutes to enhance coronary and cerebral perfusion in children.

Incorrect. A compression fraction >80% ensures that the majority of CPR time is spent delivering chest compressions to improve outcomes.

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

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

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

Incorrect. Biphasic defibrillators deliver effective shocks within the range of 120-200 J to treat VF or pulseless VT.

Incorrect. Continuous chest compressions are performed while ventilations are delivered every 6 seconds when an advanced airway is in place.

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

Incorrect. Oxygenation and ventilation should be optimized to avoid hypoxia or hyperoxia during post-cardiac arrest care.

Incorrect. Magnesium sulfate is administered to stabilize the myocardium and terminate torsades de pointes.

Incorrect. ROSC stands for "Return of Spontaneous Circulation," indicating the resumption of a perfusing rhythm.

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

Incorrect. Activating EMS ensures help is on the way while you assess and initiate resuscitation.

Incorrect. The correct compression rate for CPR is 100-120 compressions per minute to optimize perfusion and prevent fatigue.

Incorrect. VF is a shockable rhythm requiring immediate defibrillation to restore organized electrical activity.

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

Incorrect. Hypothermia is a reversible cause of cardiac arrest and should be addressed during resuscitation efforts.

Incorrect. Adenosine is administered as a rapid IV push to terminate SVT in pediatric patients, followed by a saline flush.

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

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

Incorrect. Pediatric defibrillation begins at 2 J/kg and increases to 4 J/kg for subsequent shocks if needed.

Incorrect. Symptomatic second-degree AV block type II can progress to complete heart block, requiring pacing.

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

Incorrect. Requires immediate defibrillation to restore organized cardiac activity.

Incorrect. Ventilations are delivered at a rate of 6-8 breaths per minute to prevent hyperventilation.

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

Incorrect. Amiodarone is administered as a 300 mg IV/IO bolus for refractory VF or pulseless VT.

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

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

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