During ACLS training, which rhythm requires immediate defibrillation as the first intervention?
Answer: Ventricular fibrillation
Ventricular fibrillation is a shockable rhythm that requires immediate defibrillation to restore organized electrical activity.
A patient in cardiac arrest has been receiving CPR for 2 minutes. The monitor shows organized electrical activity but no pulse is detected. What is the most likely rhythm?
Answer: Pulseless electrical activity (PEA)
PEA is characterized by organized electrical activity on the monitor without a detectable pulse.
Which of the following is a reversible cause of cardiac arrest represented by the 'H's and T's'?
Answer: Hypovolemia
Hypovolemia is one of the 'H' reversible causes of cardiac arrest and should be treated with fluid resuscitation.
During ACLS simulation, a student administers amiodarone for refractory VF. What is the correct initial IV/IO dose?
Answer: 300 mg
The initial dose of amiodarone for refractory VF/pulseless VT is 300 mg IV/IO bolus.
In ACLS certification, what is the recommended compression-to-ventilation ratio for a single rescuer performing CPR on an adult?
Answer: 30:2
The 30:2 ratio is standard for single-rescuer adult CPR to balance compressions with ventilations.
A patient with ROSC after cardiac arrest has a SpO2 of 94%. Which action is most appropriate per ACLS post-cardiac arrest care guidelines?
Answer: Titrate O2 to maintain SpO2 of 92–98%
Post-ROSC care guidelines recommend titrating oxygen to avoid hyperoxia, targeting SpO2 of 92–98%.
During ACLS megacode practice, when should chest compressions be paused?
Answer: Only to deliver a shock or check pulse after rhythm change
Compressions should be paused only to deliver a defibrillation shock or to check for a pulse after a rhythm change suggesting ROSC.
