## Chain of Survival - CPR Questions 1. **Which of the following is the first link in the adult Chain of Survival?** - Early defibrillation - Early advanced care - Early CPR - **Early recognition and activation of the emergency response system** Early recognition and activation of the emergency response system is crucial as it ensures that help is on the way and increases the chances of survival. 2. **What is the second step in the adult Chain of Survival?** - Early CPR - Early defibrillation - Post-cardiac arrest care - Advanced life support Early CPR is the second step and is critical for maintaining blood flow to the brain and vital organs until defibrillation can be performed. 3. **The final link in the Chain of Survival focuses on:** - Early defibrillation - Advanced life support - **Post-cardiac arrest care** - Calling 911 Post-cardiac arrest care is vital for the recovery and long-term survival of cardiac arrest patients. 4. **What is the recommended chest compression rate for adult CPR according to the 2015 guidelines?** - 60-80 compressions per minute - 80-100 compressions per minute - **100-120 compressions per minute** - 120-140 compressions per minute The 2015 guidelines recommend a compression rate of 100-120 compressions per minute to ensure adequate blood flow during CPR. 5. **According to the 2015 BLS guidelines, the depth of chest compressions for adults should be:** - At least 1 inch - **At least 2 inches** - At least 3 inches - At least 4 inches Chest compressions should be at least 2 inches deep to be effective. 6. **What major change was made in the 2010 BLS guidelines?** - **Airway, Breathing, Compressions (ABC) was changed to Compressions, Airway, Breathing (CAB)** - The use of AEDs was discouraged - Chest compressions were removed from the protocol - Ventilations were prioritized over compressions The change to CAB emphasizes the importance of chest compressions in the initial response. 7. **When performing adult CPR, how often should rescuers switch roles to prevent fatigue?** - Every 1 minute - **Every 2 minutes** - Every 5 minutes­ - Every 10 minutes Rescuers should switch roles every 2 minutes to ensure high-quality chest compressions are maintained. 8. **When performing one-rescuer CPR on an adult, the compression to ventilation ratio is:** - 15:1 - 15:2 - 30:1 - **30:2** The recommended ratio for one-rescuer CPR is 30 compressions to 2 ventilations. 9. **If an adult victim has a pulse but is not breathing, you should:** - Start chest compressions immediately - Perform abdominal thrusts - **Provide rescue breaths** - Check the blood pressure If the victim has a pulse but is not breathing, providing rescue breaths helps maintain oxygenation. 10. **In two-rescuer CPR for adults, the role of the second rescuer is to:** - Call 911 - Perform chest compressions - **Provide ventilations and operate the AED** - Check for a pulse The second rescuer provides ventilations and operates the AED, while the first rescuer performs chest compressions. 11. **When using a pocket mask for mouth-to-mask ventilation, you should:** - Blow as hard as possible - Use a compression to ventilation ratio of 15:1 - **Ensure a tight seal and deliver each breath over 1 second** - Alternate breaths between rescuers Ensuring a tight seal and delivering each breath over 1 second helps achieve adequate ventilation. 12. **During bag-mask ventilation in two-rescuer CPR, the rescuer providing ventilations should:** - Deliver one breath every 3-5 seconds - **Deliver one breath every 5-6 seconds** - Deliver one breath every 10 seconds - Deliver one breath every 15 seconds Delivering one breath every 5-6 seconds helps ensure proper oxygenation without hyperventilation. 13. **The correct hand placement for chest compressions in adults is:** - On the upper half of the breastbone - **On the lower half of the breastbone, between the nipples** - Just above the navel - On the left side of the chest Hand placement on the lower half of the breastbone ensures effective chest compressions. 14. **What is the recommended compression depth for adult CPR?** - At least 1 inch - At least 1.5 inches - **At least 2 inches** - At least 2.5 inches Compressions should be at least 2 inches deep to ensure adequate perfusion. 15. **When should an AED be applied during an adult cardiac arrest?** - **As soon as it is available** - After 5 minutes of CPR - After giving 2 rescue breaths - Only if the victim is unresponsive and not breathing The AED should be applied as soon as it is available to increase the chances of survival. 16. **What is the primary purpose of chest compressions during CPR?** - To clear the airway - To restart the heart - **To circulate blood to the brain and vital organs** - To provide oxygen to the lungs Chest compressions help circulate blood to the brain and vital organs, maintaining life until advanced care can be provided. 17. **In adult CPR, how often should you check for signs of life and a pulse?** - Every 30 seconds - Every 1 minute - **Every 2 minutes** - Every 5 minutes Checking for signs of life and a pulse every 2 minutes helps determine if CPR is effective and if further actions are needed. 18. **When performing CPR on an adult, you should minimize interruptions to:** - **10 seconds or less** - 20 seconds or less - 30 seconds or less - 1 minute or less Minimizing interruptions to 10 seconds or less ensures continuous blood flow and improves the chances of survival. 19. **What is the correct sequence of steps for using an AED?** - **Power on the AED, attach electrode pads, analyze the rhythm, deliver a shock** - Power on the AED, analyze the rhythm, attach electrode pads, deliver a shock - Attach electrode pads, power on the AED, analyze the rhythm, deliver a shock - Analyze the rhythm, power on the AED, attach electrode pads, deliver a shock The correct sequence ensures that the AED is ready to deliver a shock as soon as a shockable rhythm is detected. 20. **What is the recommended rate of compressions per minute in adult CPR?** - 60-80 compressions per minute - 80-100 compressions per minute - **100-120 compressions per minute** - 120-140 compressions per minute A rate of 100-120 compressions per minute helps maintain adequate circulation during CPR. 21. **How long should each breath be delivered during rescue breathing in adult CPR?** - 0.5 seconds - **1 second** - 1.5 seconds - 2 seconds Each breath should be delivered over 1 second to ensure adequate ventilation without causing gastric inflation. 22. **What is the purpose of allowing complete chest recoil after each compression?** - To increase the rate of compressions - **To allow the heart to refill with blood** - To reduce fatigue in the rescuer - To enhance airway patency Complete chest recoil allows the heart to refill with blood, ensuring effective circulation during CPR. 23. **When should you call for additional help during a CPR event?** - Immediately after starting chest compressions - After delivering the first two rescue breaths - **As soon as you recognize the victim is unresponsive and not breathing** - Only if the AED indicates a shock is needed Calling for additional help as soon as you recognize the emergency ensures timely assistance and advanced care. 24. **During two-rescuer CPR, what is the role of the rescuer performing ventilations?** - To check for a pulse - To provide compressions - **To ensure chest rise with each breath** - To apply the AED pads The rescuer providing ventilations should ensure that each breath results in visible chest rise, indicating effective ventilation. 25. **In an adult victim, what is the recommended action if you find a weak pulse but the victim is not breathing?** - Start chest compressions immediately - **Provide rescue breaths** - Apply the AED - Check for a medical alert bracelet Providing rescue breaths helps maintain oxygenation in a victim with a pulse but no breathing.
