BLS STUDY GUIDE
High quality CPR includes starting compressions within how many seconds after recognition of cardiac arrest in adults
10
A healthcare provider should check pulse for no more than
10 sec
After you identify an unresponsive victim with no breathing and no pulse, chest compressions should be initiated within
10 seconds
The proper compression rate for victims of all ages is at least
100 compressions per minute
The compression to breath ratio for 2 rescuer child CPR IS
15:2
The compression to ventilation ratio for 2-rescuer infant CPR IS
15:2
The Depth of chest compressions for an adult victim should be at least
2 inches (5 cm)
The compression to ventilation ratio for 1 rescuer adult CPR IS
30:2
To reduce rescuer fatigue during team CPR, compressor role should be switched every
5 cycles
Which of the following victims need CPR?
A victim who is unresponsive, no normal breathing and absent/inadequate pulse
Why is it important to compress to the appropriate depth during CPR?
Adequate depth of compression is needed to create blood flow during compressions
If an AED is used for a child less than 8 years of age ,
Adult pads/dose may be used if pediatric are not available
The recommended rate for performing chest compressions for victims of all ages is
At least 10 compressions per minute
The recommended depth of chest compressions for an infant is
At least one third the depth of the chest approximately 1.5 inches (4cm)
Which of the following ventilation devices/techniques is not recommended for a single rescuer to provide breaths during CPR?
Bag-mask device
If an unresponsive infant is not breathing and has a heart rate of 53 beats per minute and signs of poor perfusion despite oxygenation and ventilation with a bag and mask, which of the following should you perform?
Both chest compressions and breaths
Which of the following option lists the correct compression and ventilation rates for 2 rescuer CPR in the presence of an advanced airway?
Compress at rate of at-least 100 per minute, 1 breath every 6 to 8 seconds
Which of the following is a characteristic of high quality CPR in adults?
Compressing at depth of at least 2 inches
During bag-mask ventilation, which of the following is recommended to minimize the risk of gastric inflation?
Give a breath just until you see the chest rise
When administering breaths by using a bag-mask device for a child who is not breathing but does have a pulse the rescuer should
Give breaths at a rate of 1 breath every 3 to 5 seconds
When a child has a heart rate greater than 60 per minute and a pulse but is not breathing effectively, the rescuer should
Give breaths without chest compressions
Ideally, interruptions in chest compressions should be
Limited to less than 10 sec
Where should a rescuer attempt to palpate the brachial pulse in an infant
On the inside of the upper arm, between the elbow and the shoulder
If a victim of foreign body airway obstruction becomes unresponsive, the rescuer should send someone to activate the emergency response system and immediately
Start CPR beginning with compressions
The rescuer should deliver shock with an AED after
The AED advises a shock, charges, and prompts the rescuer to push the shock button
As soon as an AED becomes available, which of the following is the first step you should perform to operate the AED?
Turn on the AED
For which of the following would be appropriate to move an adult victim who need CPR?
When adult victim is in a dangerous environment
When should the rescuer initially ensure that the scene is safe?
When the rescuer first sees a potential victim
Complete chest recoil contributes to CPR success by
allowing the heart to refill with blood between compressions
Which of the following correctly compares characteristic of chest compressions in adults with those in infants and children
compression depth: for adults at least 2 inches; for children at least one third the depth of the chest
Gastric inflation is more likely to occur if the rescuer
gives breaths too quickly or with too much force
After the AED delivers a shock, the rescuer should
immediately restart CPR, beginning with chest compressions
The 2 thumb-encircling hands technique for the infant
is the preferred chest compression technique for 2 rescuer CPR
In 2 rescuer CPR, while the first rescuer begins chest compressions, the second rescuer should
maintain an open airway and give ventilations
Which of the following is a characteristic of high quality CPR
minimizing interruptions in chest compressions
Where should the hands be placed to perform chest compressions on an adult?
on the lower half of the breastbone
The rescuer knows the rescue breath for an infant victim is effective when
the chest rises visibly
After the airway is opened, which of the following correctly states the proper technique for delivering mouth-to-mouth ventilation?
the rescuer opens the airway seals his or her mouth over the victim's mouth, pinches the victim's nose closed, and gives 2 breaths while watching for the chest to rise.
