Incorrect. Naloxone reverses opioid-induced respiratory depression, restoring normal respiratory function.

Incorrect. Stabilizes the myocardial membrane and prevents arrhythmias.

Incorrect. Pulse checks should be limited to 5-10 seconds to minimize interruptions in chest compressions.

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

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

Incorrect. Adenosine is administered as a rapid IV push to terminate SVT in pediatric patients, followed by a saline flush.

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

Incorrect. Hypothermia is a reversible cause of cardiac arrest and must be corrected to restore spontaneous circulation.

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

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

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

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

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

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

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

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

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

Incorrect. Atropine should not exceed a total dose of 3 mg when treating symptomatic bradycardia in adults.
