BLS Practice Test – 100 BLS Practice Quiz – Test Your Knowledge
This quiz covers essential Basic Life Support (BLS) skills you might need in an emergency. Test your knowledge on the correct steps for CPR, using an AED, and responding to choking victims of all ages.
The questions address key areas like:
- Checking responsiveness
- Performing CPR (chest compressions and rescue breaths)
- Using an AED
- Responding to choking in adults, infants, and children
- General BLS principles
Remember, immediate action is crucial in emergencies. If you find someone unresponsive, call emergency services and begin CPR.
This quiz is for informational purposes only and doesn’t replace proper and practical BLS training. Consider getting certified to ensure you can confidently respond to emergencies.
