What is the recommended compression-to-ventilation ratio for a single rescuer performing CPR on an adult?
Answer: 30:2
A single rescuer should use a 30:2 compression-to-ventilation ratio for adult CPR.
During ACLS, what is the maximum interval recommended between recognizing cardiac arrest and delivering the first shock with a defibrillator?
Answer: 1 minute
Time-to-shock should be minimized; the goal is to defibrillate within 1 minute of recognition when a shockable rhythm is present.
What is the primary purpose of a post-cardiac arrest care bundle following ROSC?
Answer: Prevent rearrest and optimize neurological outcomes
Post-cardiac arrest care focuses on preventing rearrest and optimizing neurological recovery through targeted temperature management and hemodynamic support.
Which rhythm is NOT considered a shockable rhythm in ACLS?
Answer: Pulseless electrical activity
Pulseless electrical activity (PEA) is a non-shockable rhythm; defibrillation is ineffective and CPR with reversible cause treatment is required.
What is the recommended rate for delivering rescue breaths during CPR when an advanced airway is in place?
Answer: 1 breath every 6 seconds
With an advanced airway in place, deliver 1 breath every 6 seconds (10 breaths/min) without pausing compressions.
Which of the following best describes the ACLS 'H's and T's' framework?
Answer: Reversible causes of cardiac arrest to identify and treat
The H's and T's are a mnemonic for reversible causes of cardiac arrest that should be identified and treated during resuscitation.
What tidal volume is recommended when delivering ventilations during CPR to avoid gastric inflation?
Answer: 500–600 mL
A tidal volume of 500–600 mL is recommended to produce visible chest rise without causing gastric inflation.
