A middle-aged man collapses. You and a second rescuer go to the victim and find that he is unresponsive, is not breathing, and does not have a pulse.12. ?Which action is most likely to positively impact his survival?A. ?Performing high-quality CPREnsuring scene safetyC. Checking the pulse frequentlyD. Providing rescue breaths13. ?You and another rescuer begin CPR. ?After a few cycles, you notice the chest compression rate is slowing. What should you say to offer constructive feedback?A. ?”You need to compress at a rate of 80 ?to 120 ?per minute.”B.”You need to compress at a rate of at least 100 ?per minute.”C.”You need to compress at a rate of 100 ?to 120 ?per minute.”D. ?”You need to compress at a rate of at least 120 ?per minute.”Use this scenario to answer the next 2 ?questions:A 67-year-old man is found unresponsive, not breathing, and without a pulse.

The correct answer and explanation is:
Correct Answers:
- Question 12:
Answer: A. Performing high-quality CPR
Explanation: High-quality CPR significantly increases the chances of survival for a person in cardiac arrest. It ensures adequate oxygen and blood delivery to vital organs, especially the brain and heart. Effective chest compressions at the correct depth (at least 2 inches) and rate (100–120 per minute), combined with minimizing interruptions, are crucial for improving outcomes until advanced care or an automated external defibrillator (AED) can be applied. Scene safety is essential, but CPR has the greatest direct impact on survival. - Question 13:
Answer: C. “You need to compress at a rate of 100 to 120 per minute.”
Explanation: Constructive feedback during CPR is important to maintain its effectiveness. The optimal chest compression rate is 100–120 compressions per minute, as supported by guidelines from the American Heart Association (AHA). If the rate falls below or exceeds this range, the effectiveness of CPR decreases due to inadequate blood circulation or fatigue of the rescuer. By providing specific and actionable feedback, rescuers can correct their technique without confusion. - Question 14:
Answer: C. About every 2 minutes
Explanation: Switching rescuers approximately every 2 minutes helps maintain high-quality chest compressions. Over time, rescuers become fatigued, which negatively impacts the depth and rate of compressions. Regular switching minimizes fatigue and ensures consistent CPR quality. The transition should be quick, ideally during rhythm analysis or AED application, to minimize interruptions in chest compressions. - Question 15:
Answer: D. Tell the compressor you notice decreased chest recoil
Explanation: Complete chest recoil is critical for allowing the heart to refill with blood between compressions. If you notice the rescuer is not allowing full recoil, provide immediate and specific feedback to correct their technique. Avoid taking over without communication unless the rescuer cannot continue or the issue persists. Open communication helps maintain teamwork and ensures the person receiving care gets the best chance of survival.
