CPR BLS Exam 2021 AHAWhy 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.)
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.)
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.)
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.)
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.)
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.)
When using a bag-mask device, how can rescuers ensure that they are providing
effective breaths? - Observing the chest rise with breaths (Squeeze the bag to give
breaths (1 second each) while watching for chest rise. Deliver each breath over 1
second, with or without supplementary oxygen.)
What ratio for compressions to breaths should be used for 1-rescuer infant CPR? - 30
compressions to 2 breaths (For 1-rescuer infant CPR, the correct compression-to-
ventilation ratio is 30:2.)
