CPR BLS Exam 2021/2022 AHA_ answered1. Why is defibrillation important?
- It can restore a regular cardiac rhythm (An AED can identify an abnormal heart rhythm
that needs a shock. The AED can then deliver a shock that can convert a rhythm back to
normal.)
2. While performing high-quality CPR on an adult patient, what action should you ensure is
being accomplished?
- Compressing to a depth of at least 2 inches (When performing chest compressions on an
adult (or adolescent), a compression depth of at least 2 inches (5 cm) should be used.)
3. A 63-year-old man collapses while mowing the lawn. He is unresponsive, is not
breathing, and does not have a pulse. A neighbor, who is an EMT, rushes to her with an
AED. When the AED arrives, what is the first step for using it?
- Turn on the AED (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.)
4. After the AED pads are attached to the victim's bare chest, the AED prompts you to
shock the victim. What is the next step when using an AED?
- Follow the AED prompts and press the shock button once everyone is clear. (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.)
5. What should you do if you need to use an AED on someone who has been submerged in
a pool?
- Pull the victim out of the water, and wipe the chest, and use the AED (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.)
6. A victim with who is choking becomes unresponsive. What is your first course of action?
- Start CPR, beginning with chest compressions (Choking victims with severe airway
obstruction may worsen and become unresponsive. If this occurs, then high-quality CPR
must be started immediately, beginning with chest compressions.)
