The correct answer and explanation is:
Correct Answers and Explanations:
Question 12:
Which action is most likely to positively impact his survival?
Answer: A. Performing high-quality CPR.
Explanation:
High-quality CPR is the most critical intervention for a person who is unresponsive, not breathing, and has no pulse. It provides oxygenated blood to vital organs, especially the brain and heart, until advanced medical help arrives or a defibrillator is available. High-quality CPR includes compressions at the correct depth (at least 2 inches for adults), proper rate (100-120 compressions per minute), allowing full chest recoil, minimizing interruptions, and delivering effective ventilations. Other options, such as ensuring scene safety and rescue breaths, are important but secondary to initiating chest compressions as soon as possible.
Question 13:
What should you say to offer constructive feedback if the chest compression rate is slowing?
Answer: C. “You need to compress at a rate of 100 to 120 per minute.”
Explanation:
Chest compressions performed at the correct rate (100-120 per minute) are critical for maintaining adequate blood flow to the brain and heart during CPR. Feedback should be specific and supportive, guiding the rescuer to achieve the optimal compression rate. Option C provides a precise, evidence-based rate and avoids vague or incorrect instructions like “at least 100 per minute” (option B) or exceeding the upper limit of 120 compressions per minute (option D). Providing constructive feedback ensures the quality of CPR is maintained.
Question 14:
When should rescuers switch positions during CPR?
Answer: C. About every 2 minutes.
Explanation:
Switching every 2 minutes minimizes fatigue, ensuring that compressions remain effective. Research shows that chest compression quality declines after 2 minutes due to rescuer exhaustion, even if the rescuer does not feel tired. Switching during AED analysis or at other natural pauses in CPR is an ideal time. Other options, like “never switching” (option A) or switching only during AED pad placement (option B), compromise the quality of CPR.
Question 15:
What should you do if the rescuer is not allowing for complete chest recoil?
Answer: D. “Tell the compressor you notice decreased chest recoil.”
Explanation:
Complete chest recoil allows the heart to refill with blood between compressions, which is essential for maintaining circulation. If recoil is not achieved, blood flow is compromised. Providing immediate, constructive feedback helps the rescuer correct their technique without interrupting CPR. Taking over immediately (option C) might demoralize the rescuer and is unnecessary unless their technique remains ineffective after feedback. Standing back or only criticizing without offering solutions (options A and B) is not helpful and could harm the victim’s chances of survival.
