unit 5 (cpr)

Question 1

where to check pulse on each class

Answer 1

unconscious child + adult is carotid. conscious child + adult is radial. infants is brachial.

Question 2

pacemaker node

Answer 2

the SA node

Question 3

electrical pathway of heart

Answer 3

SA node- cells depolarize and atrial contraction
the impulse moves down the AV node, then to bundle of his (AV bundle), up into the bundle branches via Purkinje fibers which cause ventricle contraction

Question 4

atrial systole

Answer 4

atrial depolarization (contraction)

Question 5

ventricular diastole

Answer 5

ventricles filling and relaxed

Question 6

p wave

Answer 6

first part of heart beat, atrial depolarization

Question 7

qrs complex

Answer 7

ventricular contract (depolarization)

Question 8

t wave

Answer 8

ventricular repolarization

Question 9

myocardial infarction

Answer 9

results from lack of blood flow to coronary arteries. could cause a cardiac arrest as blockage could prevent conduction of electrical currents though the heart

Question 10

adult chain of survival

Answer 10

recognize cardiac arrest, call 911, give chest compressions, early defibrillation

Question 11

pediatric chain of survival

Answer 11

recognize cardiac arrest, give 5 cycles and breaths, call 911

Question 12

if you have 2 rescuers for child CPR, how do you adjust the compression to breath ration

Answer 12

change it to 15:2

Question 13

what is the compression to breath ratio for one person infant CPR

Answer 13

30:2 until second rescuer arrives

Question 14

what is ventricular tachycardia

Answer 14

ventricle cant refill so patient appears pulseless. turns into fibrillation

Question 15

what is ventricular fibrillation

Answer 15

ventricles quiver

Question 16

pad placement of AED paddles

Answer 16

upper right and left under armpit. if pacemaker, just place the pad below it. if medication pad, take off and place paddles in correct spot. if skin is wet, dry the chest off.

Question 17

AED paddle placement on children

Answer 17

if AED arrives, finish CPR before placing. place in same spots as adult unless the child is too small and they touch, then place one over sternum and one over spine.

Question 18

what is you are doing on scene CPR and someone says the patient has a DNR

Answer 18

DNR can not be verbally confirmed, continue with CPR

Question 19

what does AED set up consist of

Answer 19

turning the device on, plugging in the pads, and putting them on the chest

Question 20

when should you not do CPR

Answer 20

valid DNR, dependent lividity, decomposition, rigor mortis, if scene is unsafe, decapitation

Question 21

when should you stop CPR

Answer 21

rescuer exhaustion, obvious signs of life, EMS arrives, physician orders you to stop, scene becomes unsafe

Question 22

what are some complications of CPR

Answer 22

gastric distention- readjust airway, regurgitation- immediately stop and turn head to clear airway, broken ribs

Question 23

what might cardiac arrest result from

Answer 23

electrical issue, lack of blood flow/oxygen (MI)
