Incorrect. Maintaining a compression fraction above 80% ensures adequate blood flow during resuscitation.

Incorrect. IO access provides a reliable alternative for rapid drug delivery during resuscitation when IV access cannot be obtained.

Incorrect. For adult CPR, the ratio ensures adequate perfusion and oxygenation when no advanced airway is in place.

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

Incorrect. Maintaining oxygen saturation at 92-96% prevents hypoxia and avoids complications associated with hyperoxia.

Incorrect. Pediatric defibrillation starts at 2 J/kg for the initial shock, increasing as needed based on the patient's response.

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

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

Incorrect. Synchronized cardioversion restores organized cardiac activity in unstable VT with a pulse, preventing progression to VF.

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

Incorrect. High-quality CPR is the primary intervention for PEA, followed by epinephrine administration and addressing reversible causes.

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

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

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

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

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

Incorrect. Stabilizes the myocardial membrane and prevents arrhythmias.

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

Incorrect. Synchronized cardioversion is used to restore a normal rhythm in unstable atrial fibrillation.

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

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