AHA Exam

after you identify an unresponsive victim with no breathing and no pulse, chest compressions should be initiated within

10 seconds

the 2010 AHA guidelines for CPR and ECC recommend that to identify cardiac arrest in an uresponsive victim with no breathing a healthcare provider should check a pulse for no more than

10 seconds

the compression to breaths 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

which of the following victims needs CPR

a victim who is unresponsive with no normal breathing and no 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

the recommended rate for performing chest compressions for victims of all ages is

at least 100 compressions per min.

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 min. and signs of poor perfusion despite oxygenation ventilation with a bag and mask, which of the following should you perform?

both chest and compressions and breaths

which of the following options lists the correct compression and ventilation rates for 2 rescuer CPR in the presence of an advanced airway?

compress at a rate of at least 100 per min. 1 breath every 6 to 8 seconds

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 the rate of 1 breath every 3 to 5 seconds

When a child has a heart rate greater than 60 per min. and a pulse but is not breathing effectively, the rescuer should

give breaths without chest compressions.

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

where should the hands be placed to perform chest compressions on an adult?

on the lower half of the breastbone

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 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.

as soon as an AED becomes available, which of the following is the first step the rescuer should perform to operate the AED

turn on the AED

when should the rescuer initially ensure that the scene is safe?

when the rescuer first sees a potential victim
