Incorrect. Chest compressions should be paused for less than 10 seconds to minimize interruptions during CPR when delivering a shock.

Incorrect. Epinephrine is repeated every 3-5 minutes during cardiac arrest to enhance perfusion pressure.

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

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

Incorrect. Maintaining a compression fraction above 80% ensures adequate blood flow during resuscitation.

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

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

Incorrect. Ventricular fibrillation presents as a disorganized rhythm that requires immediate defibrillation.

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

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

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

Incorrect. Adenosine is administered as a 0.1 mg/kg rapid IV push for pediatric SVT, followed by a saline flush.

Incorrect. Prompt defibrillation within 30 seconds of witnessed VF arrest improves the chance of restoring a perfusing rhythm.

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

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

Incorrect. TTM prevents further neurological injury by maintaining a controlled core temperature after ROSC.

Incorrect. Epinephrine is administered after defibrillation to enhance coronary and cerebral perfusion during resuscitation.

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

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

Incorrect. Synchronized cardioversion at 100 J is effective for restoring a stable rhythm in unstable ventricular tachycardia.

Incorrect. PEA is not a shockable rhythm; it is managed with high-quality CPR and addressing the underlying reversible causes.

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

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

Incorrect. Atropine is given at 0.5 mg IV every 3-5 minutes for unstable bradycardia caused by vagal stimulation or primary AV block.

Incorrect. Symptomatic second-degree AV block type II can progress to complete heart block, requiring pacing.

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

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

Incorrect. Pulse checks are performed every 2 minutes during rhythm assessments to evaluate the effectiveness of resuscitation.

Incorrect. Rhythm checks are performed every 2 minutes to evaluate for shockable rhythms and assess the effectiveness of interventions.

Incorrect. Thrombosis (pulmonary or coronary) is a reversible cause of cardiac arrest and should be addressed immediately.

Incorrect. A supine position ensures proper electrode placement and effective delivery of defibrillation shocks.

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

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

Incorrect. Epinephrine is administered every 3-5 minutes during pediatric cardiac arrest to enhance coronary and cerebral perfusion.

Incorrect. Epinephrine 1 mg IV/IO is administered every 3-5 minutes during cardiac arrest to improve coronary and cerebral perfusion.

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

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

Incorrect. Hypokalemia can cause cardiac arrhythmias and is included in the "H's" of reversible causes of cardiac arrest.

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

Incorrect. PETCO2 readings above 10 mmHg during CPR indicate adequate chest compressions and cardiac output.
