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

Incorrect. Atropine at 0.5 mg IV is the first-line treatment for symptomatic bradycardia caused by vagal stimulation.

Incorrect. First-line treatment to block vagal stimulation and increase heart rate.

Incorrect. TTM is used to reduce neurological injury post-ROSC by maintaining a core temperature of 32-36°C.

Incorrect. The jaw-thrust avoids neck movement, making it the preferred airway technique for patients with suspected cervical spine injuries.

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

Incorrect. Adenosine is administered as a rapid IV push at an initial dose of 6 mg to terminate stable SVT.

Incorrect. The 15:2 ratio improves oxygenation and circulation during high-quality infant CPR performed by two rescuers.

Incorrect. Atrial fibrillation is cardioverted starting at 120-200 J in synchronized mode to avoid delivering the shock during ventricular repolarization.

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

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

Incorrect. The jaw thrust technique opens the airway while minimizing cervical spine movement, reducing the risk of further injury.

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

Incorrect. CPR should be resumed immediately after defibrillation to maintain perfusion and increase the likelihood of ROSC.

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

Incorrect. Immediate defibrillation is critical for shockable rhythms like ventricular fibrillation and pulseless VT.

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

Incorrect. Rescuers should switch roles every 2 minutes to maintain high-quality chest compressions and prevent fatigue.

Incorrect. VF is a shockable rhythm, and defibrillation is the primary treatment to restore an organized rhythm.

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

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

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

Incorrect. CPR is the primary treatment for PEA, along with epinephrine and addressing reversible causes to restore circulation.

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

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

Incorrect. A 30:2 ratio ensures adequate oxygenation and circulation when no advanced airway is present.

Incorrect. PEA is treated with CPR, epinephrine, and identifying reversible causes to restore organized electrical activity.

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

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

Incorrect. Hypovolemia is a reversible cause of cardiac arrest that can be treated with fluid resuscitation to restore circulation.

Incorrect. Calling for help ensures timely assistance and access to advanced resuscitation equipment.

Incorrect. VF is a shockable rhythm, and defibrillation is the most effective intervention to restore a normal rhythm.

Incorrect. Early defibrillation within 30 seconds of a witnessed VF arrest increases survival rates significantly.

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

Incorrect. Epinephrine is given at a dose of 1 mg IV/IO every 3-5 minutes during adult cardiac arrest to improve perfusion.

Incorrect. The jaw thrust maneuver opens the airway without moving the cervical spine, reducing the risk of spinal injury.

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

Incorrect. The jaw thrust maneuver opens the airway without manipulating the cervical spine, protecting against spinal cord injury.

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

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

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