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 The correct answer is D. When performing chest compressions on an adult (or adolescent), a compression depth of at least 2 inches (5 cm) should be used. [BLS Provider Manual, Part 2: BLS for Adults Adult Chest Compressions; page 19] 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 The correct answer is C. The first step for using an AED (when it becomes available) is to power on the AED if needed. Some devices will power on automatically when you open the lid or case. Because AEDs vary according to the model and manufacturer, it is important to become familiar with the AED used in your particular setting. [BLS Provider Manual, Part 3: Automated External Defibrillator for Adults and Children 8 Years of Age and Older Using the AED Universal Steps for Operating an AED; page 35] 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 The correct answer is B. After the AED pads are attached to the victim’s bare chest, you should follow the AED prompts. The AED will analyze the victim’s heart rhythm and prompt you to deliver a shock if needed. [BLS Provider Manual, Part 3: Automated External Defibrillator for Adults and Children
