Cpr Test Questions And Answers

CPR Test Questions and Answers: A Comprehensive Guide

Cardiopulmonary resuscitation (CPR) is a life-saving technique that's crucial to know in emergency situations. This comprehensive guide provides a range of CPR test questions and answers, covering essential aspects of adult, child, and infant CPR, along with automated external defibrillator (AED) use. Mastering this material will boost your confidence and preparedness in handling cardiac arrests. This guide is for educational purposes and should not replace a certified CPR training course. Always participate in a hands-on CPR course for proper certification.

Section 1: Adult CPR

1. What are the steps involved in performing adult CPR?

The steps are:

1. Check for responsiveness: Gently shake the person and shout, "Are you okay?"
2. Call for help: Dial emergency services (911 or your local equivalent). If you are alone, perform CPR for 2 minutes before calling 911.
3. Check for breathing and pulse: Look for chest rise and fall. Feel for a carotid pulse (on the neck). If there's no breathing or pulse, start CPR.
4. Chest compressions: Position your hands in the center of the chest, interlock your fingers, and push hard and fast at a rate of 100-120 compressions per minute, depth of at least 2 inches.
5. Rescue breaths: Give two rescue breaths after every 30 chest compressions, ensuring a visible chest rise.
6. Continue CPR: Continue cycles of 30 compressions and 2 breaths until help arrives or the person shows signs of life.

2. What is the proper hand placement for adult chest compressions?

The heel of one hand should be placed in the center of the chest, between the nipples. The other hand is placed on top, interlacing the fingers. Avoid compressing on the lower ribs or xiphoid process (the bony tip at the bottom of the sternum).

3. What is the correct compression depth for an adult?

At least 2 inches (5cm).

4. What is the correct compression rate for an adult?

100-120 compressions per minute. A metronome or CPR training device can help maintain the correct rate.

5. How do you perform rescue breaths in an adult?

Tilt the head back and lift the chin. Pinch the nose closed and give two slow breaths, each lasting about 1 second, ensuring visible chest rise.

Section 2: Child CPR

6. What constitutes a child in the context of CPR?

A child is generally considered to be someone between the ages of 1 year and puberty (or approximately 8-12 years old).

7. What are the key differences between adult and child CPR?

• Compression depth: About 2 inches (5cm) for adults, about 2 inches (5cm) for children.
• Rescue breaths: The technique remains similar, but the volume of air delivered might be slightly less than for an adult.
• Compressor to Breather Ratio: 30:2 compressions to breaths remain the same for both adults and children.
• Checking for a Pulse: Check for a carotid pulse in a child.
• Two-Rescuer CPR: In a two-rescuer scenario, the compression-to-ventilation ratio changes to 15:2.

8. What is the appropriate hand placement for child chest compressions?

Use one or two hands, depending on the child's size. For smaller children, use one hand; for larger children, use two hands positioned as in adult CPR. The hands should be placed in the center of the chest.

9. How do I know if a child is breathing adequately?

Look for regular chest rise and fall. Listen for breathing sounds. Feel for breath on your cheek.

Section 3: Infant CPR

10. What constitutes an infant in the context of CPR?

An infant is generally considered to be a child less than 1 year old.

11. What are the key differences between child and infant CPR?

• Compression depth: About 1.5 inches (4cm) for infants.
• Compression technique: Use two fingers for compressions on the breastbone, just below the nipple line.
• Rescue breaths: Use a mouth-to-mouth and nose technique. Cover the infant’s mouth and nose with your mouth to give a rescue breath.
• Two-Rescuer CPR: In a two-rescuer scenario, the compression-to-ventilation ratio changes to 15:2.

12. How do you perform rescue breaths on an infant?

Seal your mouth over the infant's mouth and nose and give gentle breaths, each lasting about 1 second, observing for chest rise.

Section 4: AED Use

13. What does AED stand for?

Automated External Defibrillator.

14. What is the purpose of an AED?

An AED is a portable electronic device that analyzes the heart rhythm and delivers an electric shock (defibrillation) to restore a normal heart rhythm in cases of sudden cardiac arrest.

15. What are the steps for using an AED?

1. Turn on the AED.
2. Attach the pads. Follow the AED's instructions for pad placement.
3. Analyze the heart rhythm. The AED will analyze the heart rhythm and advise whether a shock is needed.
4. Deliver the shock (if advised). Ensure no one is touching the person.
5. Perform CPR. After the shock, immediately resume CPR, starting with chest compressions.
6. Follow AED prompts. The AED will guide you through the process.

Section 5: Important Considerations

16. What are some common causes of cardiac arrest?

Sudden cardiac arrest can be caused by various factors, including heart disease, drug overdose, electric shock, drowning, and trauma.

17. What are the signs of cardiac arrest?

Signs include unresponsiveness, absence of breathing or abnormal breathing (gasping), and absence of a pulse.

18. Why is early CPR crucial?

Early CPR significantly improves the chances of survival after cardiac arrest. The brain and other organs suffer damage from lack of oxygen, and prompt CPR helps maintain blood flow.

19. What are some potential hazards in performing CPR?

While CPR is life-saving, there are some potential risks, including rib fractures, especially in older adults with brittle bones.

Section 6: Frequently Asked Questions (FAQ)

Q: How long should I continue CPR?

A: Continue CPR until the person shows signs of life, professional help arrives, or you are too exhausted to continue.

Q: What if I'm unsure if someone needs CPR?

A: If you are uncertain, it's always better to err on the side of caution and perform CPR. The consequences of not performing CPR when needed are far more severe than the risks of performing CPR when not strictly necessary.

Q: Can I harm someone by performing CPR incorrectly?

A: While there's a risk of rib fractures, the benefits of CPR far outweigh the risks of not performing it. Improper CPR is better than no CPR.

Q: What should I do if I'm uncomfortable performing CPR?

A: Call emergency services immediately. Providing basic first aid such as checking for responsiveness and calling for help is also valuable.

Q: Where can I learn CPR?

A: Many organizations offer CPR training courses, including the American Heart Association, the American Red Cross, and local community colleges. These courses provide hands-on training and certification.
