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

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

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

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

Incorrect. Early stabilization of blood pressure and oxygenation is critical to preventing further cardiac arrest after ROSC.

Incorrect. Naloxone blocks opioid receptors and is administered to reverse opioid overdose and restore adequate respiration.

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

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

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

Incorrect. Rapid defibrillation within 1 minute of witnessed VF increases the likelihood of survival and ROSC.

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

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

Incorrect. Rhythm checks are performed every 2 minutes during pauses in CPR to evaluate for shockable rhythms.

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

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

Incorrect. Magnesium sulfate stabilizes the myocardium and is the first-line treatment for torsades de pointes.

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. Rhythm checks should be performed every 2 minutes during CPR, coinciding with compressor role switches.

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

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

Incorrect. Switching every 2 minutes reduces rescuer fatigue and ensures high-quality chest compressions.

Incorrect. Defibrillation should be performed immediately after identifying VF, not delayed up to 10 minutes.

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

Incorrect. Delivering 1 breath every 5-6 seconds prevents hypoventilation or hyperventilation.

Incorrect. A rate of 100-120 compressions per minute ensures adequate circulation in pediatric patients.

Incorrect. Post-ROSC care focuses on optimizing oxygenation, ventilation, and hemodynamic stability to prevent further organ damage.

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

Incorrect. Epinephrine is the first-line drug for VF, with amiodarone as the preferred antiarrhythmic for refractory cases.

Incorrect. Delivering 6-8 breaths per minute minimizes interruptions in chest compressions and prevents hyperventilation.

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

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

Incorrect. Atropine is given at a dose of 0.5 mg every 3-5 minutes during bradycardia, up to a maximum dose of 3 mg.

Incorrect. PEA is treated with epinephrine and high-quality CPR to address underlying reversible causes.

Incorrect. A single rescuer performs 30 compressions followed by 2 breaths to maximize perfusion and oxygenation in pediatric CPR.

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

Incorrect. Pulseless VT is treated with defibrillation, not atropine. Atropine is used for symptomatic bradycardia.
