What action supports 2-rescuer CPR? A. Alternating the AED role every 2 minutes B. Alternating the compressor role every 2 minutes C. Alternating giving rescue breaths every 3 cycles D. Alternating giving shocks every 3 cycles ans: B. Alternating the compressor role every 2 minutes "Members of the team know their boundaries and ask for help before the resuscitation attempt worsens." Match this statement with the most appropriate element of team dynamics listed. A. Knowledge sharing B. Summarizing and reevaluation C. Constructive intervention D. Knowing your limitations ans: D. Knowing your limitations A victim with a foreign-body airway obstruction becomes unresponsive. What is your first course of action? A. Start CPR, beginning with chest compressions B. Roll the victim over and perform back blows C. Perform abdominal thrusts D. Perform blind finger sweeps ans: A. Start CPR, beginning with chest compressions Why is defibrillation important? A. It prevents cardiac arrest from occurring B. It is not important for cardiac arrest C. There is a 100% success rate in regaining a normal cardiac rhythm D. It can restore a regular cardiac rhythm ans: D. It can restore a regular cardiac rhythm You witness someone suddenly collapse. The person is unresponsive, you hear gasping sounds, and there is no pulse. What should you do next? A. Begin CPR; the gasps are not normal breathing B. Give rescue breaths only; the gasps are not normal breathing C. Monitor the patient; the gasps are considered normal breathing D. Begin CPR, even though gasping is normal breathing ans: A. Begin CPR; the gasps are not normal breathing Use this scenario to answer the next 2 questions: 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. Which action is most likely to positively impact this victim's survival? A. Performing high-quality CPR B. Ensuring scene safety C. Providing rescue breaths D. Checking the pulse frequently ans: A. Performing high-quality CPR 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 120 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 100 per minute." ans: C. "You need to compress at a rate of 100 to 120 per minute." How do you perform chest compressions when providing high-quality CPR to a child victim? A. By compressing the chest at least one third the depth of the chest, about 2 inches (5 cm) B. By compressing the chest at least one fourth the depth of the chest, about 1.5 inches (4 cm) C. By compressing the chest at least two thirds the depth of the chest, about 4 inches (10 cm) D. By compressing the chest at least one half the depth of the chest, about 3 inches (8 cm) ans: A. By compressing the chest at least one third the depth of the chest, about 2 inches (5 cm) When performing CPR on an unresponsive choking victim, what modification should you incorporate? A. There are no modifications to CPR for an unresponsive choking victim B. You do not give breaths to an unresponsive choking victim C. Each time you open the airway, look for the obstructing object D. Attempt a jaw thrust instead of a head tilt—chin lift ans: C.
