Question 1

Supply the heart muscle with oxygen to feed the heart muscle

Answer 1

The Coronary Arteries

Question 2

Gets oxygenated blood via the AORTA

Answer 2

The coronary arteries

Question 3

Contraction of the myocardium

Answer 3

Systole

Question 4

Relaxation of mycardium

Answer 4

Diastole

Question 5

Amount of blood pumped by each ventricle in 1 minute

Answer 5

Cardiac output

Question 6

History of present illness, past health history, past and current medications, and surgery or other treatments

Answer 6

Subjective data, health information

Question 7

List sight common sights for palpating arteries

Answer 7

Carotid (neck), brachial (inner bend of elbow), radial (wrist), ulnar (pinky side of wrist), femoral (groin), popliteal (behind knee), posterior tibial, doralis pedis

Question 8

List Geriatric Cosiderations

Answer 8

• Age alters the cardiovascular response to physical and emotional stress.
• Heart valves become thick and stiff (tricuspid, mitral, pulmonary and aortic)
• Frequent need for pacemaker as well as replacing pacemaker
• Increase in SBP; decrease or no change in DBP

Question 9

Blood studies, chest x-ray, electrocardiogram

Answer 9

Diagnostic Test

Question 10

Chemical found after a myocardial infarction. Maybe found in agina patients.

Answer 10

Triponin

Question 11

Measuring the size of the heart.

Answer 11

Chest x-ray

Question 12

Picture of the exact measurements of the heart from 12 angles

Answer 12

Resting ECG

Question 13

Picture of the heart

Answer 13

Event monitor or loop recorder

Question 14

Places on chest for 1 or 2 days and it tapes your heart for 3 days and a diary is kept to explain

Answer 14

Halter monitor

Question 15

Heart pumps blood through the body

Answer 15

Conduction

Question 16

This is accomplished by contraction and relaxation of the cardiac muscle tissue in the myocardium layer.

Answer 16

Conduction

Question 17

The electrical conduction system controls the heart rate

Answer 17

Cardiac conduction system

Question 18

Explain conduction in the sinoatrial node

Answer 18

Located in the back wall of the right atrium near the entrance of vena cava,
Initiates impulses 70-80 times per. In without any nerve stimulation from brain. ( normal pulse is 78-82)
Establishes basic rhythm of the heartbeat
This is where the pulse rate is

Question 19

Called the pace maker of the heart

Answer 19

Sinoatrial node

Question 20

Impulses move through atria causing two atria to contract

Answer 20

sinoatrial node

Question 21

At the same time. Impulses reach the second part of the conduction system

Answer 21

Sinoatrial Node

Question 22

Located in the bottom of the right atrium near the septum.

Answer 22

Atrioventricular Node

Question 23

What does cells in the AV node do?

Answer 23

Conduct impulses more slowly, so there is no delay as impulses travel through the the node

Question 24

Allows time do aria to finish contraction before ventricles begin contacting

Answer 24

Atrioventricular Node

Question 25

What does the AV bundle branch form and what does it do?

Answer 25

The AV bundle branch to form the Purkinjie fibers that transmit the impulses to the myocardium

Question 26

Muscle tissues

Answer 26

Myocardium

Question 27

The function of the bundle of his, bundle branches and Purkinjie fibers

Answer 27

Transmits quickly and cause both ventricles to contract

Question 28

What like a phone tree

Answer 28

The bundle of His, bundle branches , and the Purkinjie fibers

Question 29

From the AV node, impulses travel through right and left and

Answer 29

Left bundle branches and these branches extend to the right and left sides of the septum and the bottom of the heart

Question 30

As the ventricles contract what's happens and what is this called?

Answer 30

As the ventricles contract, blood is forced out through the semilunar valves into the pulmonary trunk and the aorta.

Question 31

What happens after the ventricles complete their contraction phase?

Answer 31

They relax and the SA node initiates another impulse to start another cardiac cycle.

Question 32

What does the conduction systems consist of?

Answer 32

1- Sinoatrial node (SA) 2- Atrioventricular node (AV node) 3- Bundle of His 4- Right & Left Bundle Branches which lead to the Purkinje fibers
