Chapter 31: Cardiac

Question 1

Normal pulse for newborn-infants

Answer 1

130-160 bpm

Question 2

What effects the function of Cardiac output

Answer 2

Heart rate x stroke volume

Question 3

Echocardiograph

Answer 3

Uses ultrasonic waves to produce echoes to form a latter to evaluate the hearts function and detect myocardial thickness and motion

Question 4

What part of the heart attaches to the diaphragm and serial wall?

Answer 4

Epicardium

Question 5

Layers of heart

Answer 5

Epicardium
Myocardium
Endocardium

Question 6

Cardiac catheterization

Answer 6

Helps visualize coronary arteries and identify possible narrowing

Question 7

Beta blockers function

Answer 7

Reduce blood pressure

Question 8

What blood vessels are the primary regulators of blood flow

Answer 8

Arterioles

Question 9

Annual check up of BP occurs after what age?

Answer 9

After 3 years of age, BP should be measured annually

Question 10

Diastole

Answer 10

Atrias fill with blood (valves are closed)

Question 11

Atrial systole

Answer 11

Contraction of atria pumps blood into ventricles

Question 12

Ventricular systole

Answer 12

Contraction of ventricles pump blood into aoric and pulmonic arteries

Question 13

S1

Answer 13

Tricuspid and mitral valves

Loudest at apex of the heart

Question 14

S2

Answer 14

Aortic and pulmonic

Question 15

Abnormal heart sounds

Answer 15

S3-after S2= congested heart failure
S4-before S1 = hypertension
Murmur

Question 16

What does stroke volume depend on

Answer 16

Accommodation of incoming blood volume
Contraction of heart
Resistance of blood flow

Question 17

SA node

Answer 17

Pace maker=originates and stimulate contraction to atria

Question 18

AV node

Answer 18

Sends impulse into ventricles

Question 19

Pulmonary embolism

Answer 19

Thrombus at the pulmonary system

Question 20

Myocardial Ischemia

Answer 20

Decrease back flow to you heart which prevent heart from reviewing oxygen

Question 21

Atherosclerosis

Answer 21

Built up of cholesterol, plaque, fats in artery wall that causes restricted blood flow

Question 22

Aneurism

Answer 22

Ballooning and weakened area in artery

Question 23

Thrombus

Answer 23

Blood clot

Question 24

Embolus

Answer 24

Break of thrombus and travels in circulation

Question 25

Rubs

Answer 25

Valves rubbing against each other

Question 26

Radiography

Answer 26

Establish size and shape of heart and aorta

Question 27

Exercise testing

Answer 27

Assess response to cardiovascular stress and any ischemia
