ACLS Practice Test Questions
1. What actions should you take after providing a shock with an AED?
- Provide a rescue breath
- Allow time for the AED to reanalyze the rhythm
- Check for a pulse

2. What is the appropriate compression-to-ventilation ratio during single-provider CPR where an advanced airway has yet to be placed?
- 10:1
- 15:2
- 5:1
- 30:2
3. During CPR on a patient with an advanced airway in place, which of the following is true?
- Chest compressions should be stopped while giving breaths
- Alter between chest compressions and rescue breaths
- Prioritize reaching 20 or more breaths per minute
- One breath every 6 seconds should be provided
4. What is the most critical intervention during a witnessed sudden cardiac arrest?
- Early defibrillation
- High-quality chest compressions
- Establishing IV access

- They should be coupled with finger sweeps
- They should be no more than 30 seconds
- They should be ten seconds or less
6. How often should rescue breaths be delivered in patients who are in respiratory arrest with a perfusing rhythm?
- Every 5-6 seconds
- Every 10-12 seconds
- Every 6 seconds
- Every 10 seconds
7. Which of the following is not part of the initial BLS assessment?
- Get an AED
- Establish IV access

8. The success of any resuscitation attempt is built on what combination of factors?
- High quality CPR and a through primary assessment
- Early defibrillation when indicated and establishing IV access
- Thorough primary assessment and establishing IV access
- High quality CPR and early defibrillation when indicated
9. Which of the following is considered the most vital algorithm in the context of ACLS?

10. How long should a carotid pulse check last during CPR before resuming compressions?
- 3-7 seconds
- 5-10 seconds
- 4-8 seconds
- 5-20 seconds
11. What intervention would you take to improve the underlying issue if a known alcoholic collapses and is found to be in torsades de pointes?
- Rewarm the individual to correct hypothermia.
- Administer magnesium sulfate 1 to 2 gm IV diluted in 10 mL D5W to correct low magnesium.
- Administer glucose to correct hypoglycemia.
- Administer naloxone to correct a narcotic overdose.
12. The correct sequence of electrical activity in the heart for a normal sinus rhythm would be the following:
- SA node, AV node, Bundle of His, Purkinje fibers
- SA node, Purkinje, AV node, Bundle of His
- AV node, SA node, Bundle of Hers, Purkinje fibers
- Purkinje, Bundle of His, AV node, SA node
13. What next step would you take if you were transporting a person that went into cardiac arrest and IV access is not possible?
- Terminate resuscitation
- Obtain intraosseous access
- Place a central line
- Administer all medications through ET tube
