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

Incorrect. Oxygenation and ventilation should be closely monitored to prevent hypoxia and hyperoxia.

Incorrect. A left lateral tilt prevents aortocaval compression, improving venous return and cardiac output during resuscitation.

Incorrect. Prevents progression to cardiac arrest by restoring a normal rhythm.

Incorrect. Vagal maneuvers stimulate the vagus nerve, often terminating narrow-complex SVT caused by reentrant circuits.

Incorrect. PEA is treated with epinephrine and high-quality CPR to address underlying reversible causes.

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

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

Incorrect. Pulseless VT is a shockable rhythm requiring immediate defibrillation to restore an organized rhythm.

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

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

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

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. Compressing 2-2.4 inches ensures effective perfusion during adult CPR while minimizing the risk of injury.

Incorrect. Asystole is a non-shockable rhythm requiring immediate high-quality CPR and epinephrine to optimize perfusion.

Incorrect. Defibrillation attempts should be separated by 2-minute CPR cycles to ensure effective perfusion and rhythm evaluation.

Incorrect. Hypothermia is a reversible cause of cardiac arrest and is treated by warming the patient to improve outcomes.

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

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

Incorrect. A rate of 100-120 compressions per minute ensures adequate circulation in pediatric patients.

Incorrect. Epinephrine at 1 mg IV every 3-5 minutes is used to enhance perfusion during cardiac arrest.

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

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