8-10mins

27
Q

What is the correct ranking of CPR importance with a pediatric patinet?

A

28
Q

What is the first action that should be taken when a neonates HR is less than 100bpm?

A

Administer positive pressure ventilations

29

Q

What to do when arriving at a scene with a bystander already doing CPR?

33
Q

A combination of difficulty breathing, feet and ankles feel tight, and relief in condition when sitting up suggests what issue?

A

Deliver each breathe over 1 second at a rate of 8 to 10 breathes per minute

38
Q

If the tricuspid valve could not close properly, where would blood back up into?

A

Right atrium

39
Q

What is the first action taken for a neonate whose HR is less than 100bpm?

A

Administer positive-pressure ventilations

40
Q

Automaticity of cardiac cells refers to what?

A

The cells ability to spontaneously depolarize

41
Q

What two major vessels does the right atria collect blood from?

A

Vena Cava

42
Q
