ACLS Provider: Course

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

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

Incorrect. Placing hands on the lower half of the sternum ensures effective chest compressions without damaging other structures.

Incorrect. Ventilations should be provided at a controlled rate of 6-8 breaths per minute to prevent hyperventilation.

Incorrect. These shockable rhythms require immediate defibrillation to restore a perfusing rhythm.

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

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

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

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

Incorrect. Two rescuers are needed to maintain high-quality CPR with an advanced airway: one for compressions and one for ventilation.

Incorrect. The compression-to-ventilation ratio for single-rescuer infant CPR is 30:2, ensuring sufficient oxygenation and circulation.

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

Incorrect. Compressing to a depth of 2-2.4 inches ensures adequate circulation without causing damage to internal organs.

Incorrect. With an advanced airway in place, compressions should continue uninterrupted while providing 10 breaths per minute.

Incorrect. Stabilizes the myocardial membrane and prevents arrhythmias.

Incorrect. Early defibrillation is critical for survival, especially in shockable rhythms like VF/VT.

Incorrect. With an advanced airway in place, compressions continue uninterrupted while breaths are delivered at 6-8 breaths per minute.

Incorrect. Amiodarone is the preferred antiarrhythmic for stabilizing wide-complex tachycardia in stable patients.

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

Incorrect. Immediate CPR is required as asystole is a non-shockable rhythm.

Incorrect. Delivers an electrical shock to depolarize the heart and restore a normal rhythm.

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

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

Incorrect. Interruptions in chest compressions should not exceed 10 seconds to maintain adequate perfusion to vital organs.

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

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

Incorrect. VF is a shockable rhythm, and immediate defibrillation is the most effective treatment.

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

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

Incorrect. Administered via rapid IV push, followed by a saline flush to terminate reentrant arrhythmias.

Incorrect. Reduces the risk of oxidative stress and worsened outcomes by preventing hyperoxia.

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

Incorrect. Hypoxia is the most frequent reversible cause of PEA and should be addressed immediately with oxygenation and ventilation.

Incorrect. Waveform capnography provides real-time confirmation of ET tube placement and ensures proper ventilation.

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

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

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

Incorrect. TTM helps reduce neurological injury after ROSC by maintaining a target temperature between 32-36°C.

Incorrect. Pausing compressions for more than 10 seconds interrupts perfusion and reduces the chances of ROSC.

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

Incorrect. Switching compressors every 2 minutes reduces rescuer fatigue, ensuring high-quality chest compressions are maintained.

Incorrect. Atropine doses should not exceed 3 mg during bradycardia management to avoid adverse effects.

Incorrect. Epinephrine is dosed at 0.01 mg/kg IV/IO during pediatric cardiac arrest to improve coronary and cerebral perfusion.

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

Incorrect. Epinephrine is given to improve perfusion pressure and increase the chance of ROSC in persistent VF.

Incorrect. Hypothermia is a reversible cause of cardiac arrest and should be treated with warming measures.

Incorrect. Biphasic defibrillators deliver effective shocks within the range of 120-200 J to treat VF or pulseless VT.

Incorrect. Atropine blocks vagal stimulation, increasing heart rate in cases of symptomatic bradycardia.

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

Incorrect. Maintains vasoconstriction, improving blood flow to vital organs during resuscitation.

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

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

Incorrect. Adenosine is the first-line drug for stable SVT, while synchronized cardioversion is used for unstable SVT.

Incorrect. Pediatric defibrillation starts at 2 J/kg to safely deliver an effective shock without causing harm.

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

Incorrect. Epinephrine at 0.01 mg/kg IV/IO is administered every 3-5 minutes to enhance coronary and cerebral perfusion in children.

Incorrect. Pulseless VT is a shockable rhythm that requires immediate defibrillation to restore a perfusing rhythm.

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

Incorrect. Stabilizes the myocardium and suppresses arrhythmias during refractory VF or pulseless VT.

Incorrect. Hypovolemia is a common reversible cause of PEA and should be addressed with rapid fluid resuscitation.

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

Incorrect. Maximum energy for monophasic defibrillators; for biphasic, follow manufacturer recommendations.

Incorrect. Maintaining oxygen saturation at 92-96% avoids hypoxia while preventing hyperoxia, which can cause further tissue damage.
