1. 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
... [Show More] 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.)
7. 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.)8. 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.)
9. What is a consideration when you are using an AED? - On a hairy chest, the
pads may not stick and may fail to deliver a shock, therefore a razor should be
used to shave the victim (Special situations may require the rescuer to take
additional actions when placing AED pads on a victim who has a hairy chest. In
this case, the AED pads may stick to the hair and not to the skin on the chest,
making it difficult to analyze the victim's heart rhythm and deliver a shock (if
needed). Most AED kits contain a razor for this reason.)
10.A 7-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 calls 911. The rescuer immediately begins CPR. Two additional
rescuers arrive to assist in the resuscitation attempt. What actions should occur
next, to support a team-based resuscitation attempt? - 2 rescuers alternate giving
high-quality chest compressions (To reduce rescuer fatigue, switch compressors
every 5 cycles (about 2 minutes) or sooner if needed. To minimize interruptions
in compressions, perform the switch when the AED is analyzing the rhythm. Take
less than 5 seconds to switch.) [Show Less]
