Incorrect. A rate of 100-120 compressions per minute ensures adequate circulation without risking incomplete recoil or excessive fatigue.

Incorrect. Immediate defibrillation is the most effective intervention for a witnessed cardiac arrest in VF.

Incorrect. Ventilations are delivered every 6-8 seconds to provide oxygenation without interrupting chest compressions.

Incorrect. Defibrillation is the priority for VF and should not be delayed for drug administration, as it is the definitive treatment.

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

Incorrect. Compressions at 1/3 the depth of the chest ensure adequate perfusion while minimizing injury to internal organs.

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

Incorrect. Waveform capnography ensures proper ET tube placement by monitoring exhaled CO? levels.

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

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

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

Incorrect. IV access is preferred for rapid administration; IO is the alternative if IV access is unavailable.

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

Incorrect. High-quality CPR is the primary treatment for asystole, along with epinephrine and addressing reversible causes.

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

Incorrect. A PETCO2 reading above 10 mmHg indicates adequate chest compressions and cardiac output during CPR.

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

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

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

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

Incorrect. Post-ROSC care focuses on maintaining oxygenation and avoiding hypoxia or hyperoxia to protect organ function.

Incorrect. Hypovolemia is a reversible cause of PEA and can be treated with rapid fluid resuscitation.

Incorrect. CPR is the primary intervention for PEA, followed by epinephrine and identification of reversible causes.

Incorrect. Adequate oxygenation and ventilation are critical to preventing hypoxia or hyperoxia after ROSC.

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

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

Incorrect. A 15:2 ratio ensures efficient oxygenation and circulation in pediatric patients during two-rescuer CPR.

Incorrect. PETCO2 monitoring provides real-time feedback on ventilation and the effectiveness of chest compressions.

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

Incorrect. PETCO2 monitoring provides real-time feedback on chest compressions and the effectiveness of CPR.

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

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

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

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

Incorrect. The recommended rate for chest compressions is 100-120 compressions per minute to maximize perfusion.

Incorrect. Naloxone reverses opioid-induced respiratory depression, restoring normal respiratory function.

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

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