1. What ratio for compressions to breaths should be used for 1-rescuer infant CPR? A. Give 5 compressions to 1 breath B. Give 15 compressions to 2 breaths C. Give 20 compressions to 2 breaths D. Give 30 compressions to 2 breaths The correct answer is D. For 1-rescuer infant CPR, the correct compression-to-ventilation ratio is 30:2. [BLS Provider Manual, Part 6: BLS for Infants and Children > Perform High-Quality Chest Compressions > Compression-to-Ventilation Ratio; page 52] 2. What should you do if you need to use an AED on someone who has been submerged in water? A. Pull the person out of the water, but do not use the AED B. Do not pull the person out of the water, and wipe the chest C. Pull the person out of the water, and wipe the chest D. Do not move the person, and do not use the AED The correct answer is C. Special situations may require the rescuer to take additional actions when placing AED pads for a victim who is immersed in water. In this case, the victim should be pulled out of the water. If the chest is covered with some water, it should be quickly wiped before attaching the AED pads. [BLS Provider Manual, Part 4: Automated External Defibrillator for Adults and Children 8 Years of Age and Older > Special Circumstances > Presence of Water or Liquids; page 40] Use this scenario to answer the next 2 questions: A 9-year-old child has suddenly collapsed. After confirming that the scene is safe, a single rescuer determines that the child is in cardiac arrest, shouts for nearby help, and activates the emergency response system by using his mobile device. He immediately begins performing high-quality CPR. Two additional rescuers immediately arrive to assist in the resuscitation attempt. 3. What actions should occur next to support a team-based resuscitation attempt? A. Two rescuers should operate the AED while the third rescuer gives breaths. B. One rescuer should give CPR while the other 2 wait for advanced life support to arrive. C. Two rescuers should alternate giving high-quality chest compressions. D. Two rescuers should alternate using the AED and giving breaths. The correct answer is C. To reduce rescuer fatigue, switch compressors every 5 cycles (about 2 minutes) or sooner if needed. Take less than 5 seconds to switch. [BLS Provider Manual, Part 3: BLS for Adults > Adult 2-Rescuer BLS > Effective Team Performance to Minimize Interruptions in Compressions; page 31] 4. Two rescuers begin high-quality CPR while the third rescuer leaves to get the AED. What action supports 2-rescuer CPR? A. Alternating giving rescue breaths every 3 cycles B. Alternating the compressor role every 2 minutes C. Alternating the AED role every 2 minutes D. Alternating giving shocks every 3 cycles The correct answer is B. To reduce rescuer fatigue, switch compressors every 5 cycles (about 2 minutes) or sooner if needed. To minimize interruptions in compressions, when an AED is present, perform the switch when the AED is analyzing the rhythm. Take less than 5 seconds to switch. [BLS Provider Manual, Part 3: BLS for Adults > Adult 2-Rescuer BLS > Effective Team Performance to Minimize Interruptions in Compressions; page 31] 5. You witness someone suddenly collapse. The person is unresponsive, you hear gasping sounds, and there is no pulse. You phone 9-1-1. What should you do next? A. Begin CPR; the gasps are not normal breathing B. Begin CPR even though gasping is normal breathing C. Monitor the patient; the gasps are considered normal breathing D. Give rescue breaths only; the gasps are not normal breathing The correct answer is A. The gasps described in this question are most likely agonal gasps. Agonal gasps are not considered normal breathing and are a sign of cardiac arrest. High-quality CPR should be started immediately. [BLS Provider Manual, Part 3: BLS for Adults > High-Quality CPR Skills: Adults > Assess for Breathing and a Pulse > Critical Concepts: Agonal Gasps; page 17] 6. Why is defibrillation important? A. There is a 100% success rate. B. It is not important for cardiac arrest. C. It prevents rearrest from occurring. D. It can r...............................................................................CONTINUED
