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

Incorrect. Asystole is a non-shockable rhythm treated with high-quality CPR and epinephrine.

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

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

Incorrect. PEA is not treated with adenosine; it is managed with CPR, epinephrine, and identifying and treating reversible causes.

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

Incorrect. Ventricular fibrillation (VF) is a shockable rhythm and requires immediate defibrillation to restore an organized rhythm.

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

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

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

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

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

Incorrect. Dopamine is used when atropine is ineffective, improving heart rate and contractility by stimulating beta receptors.

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

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

Incorrect. Hypothermia is a reversible cause of cardiac arrest and is treated by warming the patient to improve outcomes.

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

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

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

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

Incorrect. With an advanced airway in place, uninterrupted compressions improve blood flow while ventilation is delivered separately.

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

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

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

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

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

Incorrect. Adenosine 6 mg is given as a rapid IV push for terminating narrow-complex SVT caused by reentrant pathways.

Incorrect. Oxygen saturation should be maintained at 92-96% to prevent hypoxia and avoid the harmful effects of hyperoxia.

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

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

Incorrect. Rhythm checks should be performed every 2 minutes, coinciding with rescuer role switches, to evaluate for shockable rhythms.

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

Incorrect. Biphasic defibrillators deliver effective shocks within the range of 120-200 J, restoring organized electrical activity.

Incorrect. For unstable narrow, irregular tachycardias, synchronized cardioversion at 120-200 J is recommended.

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

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

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

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

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

Incorrect. Ventricular fibrillation is the most common cause of sudden cardiac arrest and requires immediate defibrillation.

Incorrect. A sudden increase in PETCO2 is a reliable indicator of ROSC, reflecting improved circulation and gas exchange.

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

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

Incorrect. Synchronized cardioversion is used to terminate unstable SVT by restoring normal electrical activity in the heart.

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

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

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