Q

Mitral Regurgitation

A

Stream of blood regurgitates back into LA during systole through incompetent mitral valve. In diastole, blood passes back into LV again along with new flow; results in LV dilation and hypertrophy

1. Elevated cholesterol 2. Elevated B/P 3. Blood sugar levels above 130mg/dl or know DM 4. Obesity 5. Cigarette smoking 6. Low activity Level 7. Length of any hormone replacement therapy for postmenopausal women
Risk Factors for CAD
26
Blowing, swishing sound indicating blood flow turbulence
Bruit
27
A sustained forceful thrusting of the ventricle during systole. It occurs with ventricular hypertrophy as a result of increased workload.
Heave (Lift)
28
A Palpable vibration. It feels like the throat of a purring cat. Signifies turbulent blood flow and accompanies loud murmurs.
Thrill
29
Varies with the person's breathing, increasing at the peak of inspiration and slowing with expiration.
Sinus Arrhythmia
30
Occurs near term or when mother is lactating; it's due to increased blood flow through the internal mammary artery
Mammary Souffle
31
1. Position of AV valve at the start of systole 2. Structure of the valve leaflets 3. How quickly pressure rises in the ventricles
The Intensity of S1 depends on what factors?
32
Unoxygenated blood levels of the heart by the way of:
Pulmonary artery
33
An area on the anterior chest that overlays the heart and great vessels
Precordium
34
The amount of blood that is ejected during systole in a minute is describe as :
Cardiac Output
35
Systematic circulation is measure by?
Blood Pressure
36
Where oxygenated blood is recieve?
Right ventricle

Base
40
What is JVD?
Jugular vein distension
41
How do you assess JVD?
Have the patient lay supine in a 30-45 degree angle and observe
42
Purpose of the Heart
Deliver blood to the circulatory system
43
Upper chambers of the heart
Atria
44
Lower chamber of the Heart
Ventricles
45
From where the atria collect blood?
Circulatory system
46
Where the atria deliver the blood
Ventricles
47
Which muscular partition separate the heart into two functional units?
The septum
48
Which are the two majors structures of the heart?
The left and right ventricles.
49
Normal findings in aging adult
1. Gradual rise in B/P 2. The aorta stiffens, dilates, and elongates 3. he chest often increases in anteroposterior diameter 4. Systolic murmurs are common
50
Occurs with right ventricular hypertrophy, as found in pulmonic valve disease, pulmonic hypertension, and chronic lung disease.
Lift (heave)
51
A \_\_\_\_\_\_ in the second and third \_\_\_\_\_ interspaces occurs with severe aortic stenosis and systemic hypertension.
Thrill, right
52
A \_\_\_\_\_\_ in the second and third \_\_\_\_\_\_ interspaces occurs with pulmonic stenosis and pulmonic hypertension.
Thrill, Left
53
Calcification of aortic valve cusps restricts forward flow of blood during systole; LV hypertrophy develops.
Aortic Stenosis
54
Calcification of pulmonic valve restricts forward flow of blood.
Pulmonic stenosis
55
The first heart sound is produced by the
Closure of the AV valves
56
Which of the guideline may be used to identify which heart sound is S1?
S1 coincides with the carotid artery pulse.
57
Which cardiac alterations occurs during pregnancy
An increase in cardiac volume and a decrease in blood pressure
58
The leaflets of the tricuspid and mitral valves are anchored by __________________ to the \_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_, which are embedded in the ventricular floor.
Chordae tendineae; papillary muscles
59
The ability of the heart to contract independently of any signals or stimulation is due to:
Automaticity
60
When auscultating the heart of a newborn within 24 hours after birth, the examiner hears a continuous sound that mimics the sound of a machine. This finding most likely indicates:
An expected sound caused by nonclosure of the ductus arteriosus.
61
A bruit heard while auscultating the carotid artery of a 65-year-old patient is caused by:
Turbulent blood flow through the carotid artery.
62
The jugular venous pressure is an indirect reflection of the:
Heart's efficiency as a pump.
63
The semilunar valves separate the:
