Basic Life Support Exams A and B Questions & Answers 2022

While performing high-quality CPR on an adult, what action should you ensure is being accomplished? A. Maintaining a compression rate of 90 to 120/min B. Placing hands on the upper third of the sternum C. Allowing the chest to recoil 1 inch D. Compressing to a depth of at least 2 inches Use this scenario to answer the next 2 questions: A 53-year-old woman collapses while gardening. She is unresponsive, is not breathing, and does not have a pulse. A neighbor, who is an emergency medical technician, rushes to her with an AED. 2. When the AED arrives, what is the first step for using it? A. Apply the pads to the patient’s chest B. Clear the patient C. Turn on the AED D. Press the shock button 3. After the AED pads are attached to the victim’s bare chest, the AED detects ventricular fibrillation. What is the next step when using an AED? A. Check the victim for a carotid pulse B. Follow the AED prompts C. Clear the patient D. Press the shock button 4. What should you do if you need to use an AED on someone who has been submerged in water? A. Do not move the victim, and do not use the AED B. Pull the victim out of the water, but do not use the AED C. Pull the victim out of the water, and wipe the chest D. Do not pull the victim out of the water, but wipe the chest before placing pads 5. How can rescuers ensure that they are providing effective breaths when using a bag-mask device? A. Observing the chest rise with breaths B. Delivering breaths quickly and forcefully C. Always having oxygen attached to the bagWhen performing CPR on an unresponsive choking victim, what modification should you incorporate? A. Each time you open the airway, look for the obstructing object B. There are no modifications to CPR for an unresponsive choking victim C. Attempt a jaw thrust instead of a head tilt‒chin lift D. You do not give breaths to an unresponsive choking victim The correct answer is A. Each time you open the airway to give breaths, open the victim’s mouth wide and look for the object. If you see an object that can be easily removed, remove it with your fingers. If you do not see an object, continue CPR.

A. Summarizing and reevaluation B. Knowledge sharing C. Knowing your limitations D. Constructive intervention The correct answer is C. Every member on the team should know his or her limitations, and the team leader should be aware of them. Each team member should ask for assistance and advice early, not when the situation starts to get worse.

Rapid defibrillation is a link in the adult Chain of Survival. Why is this important to survival? A. It prevents respiratory arrest B. It eliminates the abnormal heart rhythm C. It prevents cardiac arrest D. It provides normal respiration The correct answer is B. An AED can help terminate an abnormal rhythm and restore a regular heart rhythm. When used in combination with high-quality CPR, an AED can double (or triple) the chances of survival. [BLS Provider Manual, Part 1: General Concepts The Chain of Survival Importance of Each Link in the Chain of Survival; page 8] 4. Why is allowing complete chest recoil important when performing high-quality CPR? A. The heart will adequately refill between compressions B. There will be a reduction of rescuer fatigue C. The rate of chest compressions will increase D. It will reduce the risk of rib fractures The correct answer is A. Allowing complete chest recoil (between compressions) permits blood to flow into the heart. Incomplete chest recoil is inefficient because it reduces the blood flow created by chest compressions. [BLS Provider Manual, Part 2: BLS for Adults Adult Chest Compressions Foundational Facts: Chest Recoil; page 20] 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. 5. Which action is most likely to positively impact this victim’s survival? A. Ensuring scene safety B. Providing rescue breaths C. Checking the pulse frequently D. Performing high-quality CPR The correct answer is D. Performing high-quality CPR has been shown to improve a victim’s chances of survival. [BLS Provider Manual, Part 1: General Concepts High-Quality CPR; page 3] 6. 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 at least 100 per minute.” B. “You need to compress at a rate of 80 to 120 per minute.” C. “You need to compress at a rate of at least 120 per minute.” D. “You need to compress at a rate of 100 to 120 per minute.” The correct answer is D. Sometimes a team member may need to correct actions that are incorrect or inappropriate. In this case, you notice the chest compression rate is slowing. You should remind the other rescuer that a compression rate of 100 to 120/min should be used. Any person on the team should stop someone else from making a mistake, regardless of his or her role on the team.
