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

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

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

Incorrect. Adult defibrillation with a biphasic defibrillator typically starts at 120-200 J, not 360 J, depending on the manufacturer's guidelines.

Incorrect. Dopamine is used to improve heart rate and contractility in bradycardia unresponsive to atropine.

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

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

Incorrect. Chest compressions for infants should be about 1/3 the depth of the chest, approximately 1.5 inches (4 cm).

Incorrect. Administered every 3-5 minutes to restore circulation by increasing coronary and cerebral perfusion pressure.

Incorrect. Pulseless VT is treated with defibrillation, while synchronized cardioversion is reserved for tachyarrhythmias with a pulse.

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

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

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

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

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

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

Incorrect. Targeted temperature management improves neurological outcomes by preventing further brain injury.

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

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

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

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

Incorrect. Hypovolemia is a reversible cause of cardiac arrest and should be corrected with fluid resuscitation.

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

Incorrect. PEA is treated with CPR and epinephrine, as defibrillation is ineffective for non-shockable rhythms.

Incorrect. PETCO2 monitoring provides continuous feedback on the quality of chest compressions and the effectiveness of resuscitation.

Incorrect. Providing 6-8 breaths per minute ensures adequate oxygenation and ventilation without interfering with chest compressions.

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

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

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

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

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

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

Incorrect. With an advanced airway, compressions continue uninterrupted while ventilation is provided at a rate of 10 breaths per minute.

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

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

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

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

Incorrect. Epinephrine is given as a continuous infusion to maintain adequate heart rate and perfusion when atropine is ineffective.

Incorrect. A 15:2 ratio is used during pediatric CPR with two rescuers to optimize ventilation and circulation.

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

Incorrect. The maximum dose of atropine for bradycardia is 3 mg, with doses given at 0.5 mg intervals every 3-5 minutes.

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

Incorrect. Atropine is the first-line drug for treating symptomatic bradycardia by increasing heart rate through vagal inhibition.

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

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

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

Incorrect. Lidocaine is an antiarrhythmic drug used as an alternative to amiodarone for VF or pulseless VT.

Incorrect. VF is a shockable rhythm requiring immediate defibrillation to restore an organized cardiac rhythm.

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