Q

Cultural and Genetic Considerations for Smoking

A

nicotine increases the risk of myocardial infarction and stroke by increasing the oxygen demand, but having a decrease in oxygen supply, changing lipid profiles and activating platelets and fibrinogen which are clot forming agents.

Q

Cultural and Genetic Considerations for Cholesterol

A

whites, mexican americans and african americans - both male and female - highest groups of elevated LDLs which gradually contributes to thrombus formation in arteries and leads to MI’s and strokes

A
  1. Palpitation
  2. Auscultation
  3. Inspection
40
Q

Cardiac Palpitation

A
  1. Palpate carotid artery bilaterally
  2. Palpate the apical impulse
  3. Palpate precordium - note any other pulsations or thrills, normally none
41
Q

Cardiac Inspection

A
  1. Inspect for jugular venous distension.

2. Inspect the anterior chest.

42
Q

Cardiac Auscultation

A
  1. Auscultate the carotid artery
  2. Auscultation of anterior chest.
  3. Auscultation of apical heart rate
43
Q

Inspect jugular venous distension

A
  • position pt supine w/ head/neck elevated approx. 30-45 degree angle.
  • instruct pt to turn head away from examiner and observe for distension.
44
Q

Inspect anterior chest

A

you may or may not see the apical impulse.

note other pulsations, heaves or lifts.

45
Q

Heaves or lifts

A

forceful thrusting

46
Q

Auscultate the carotid artery

A

for the presence of a bruit with the bell of the stethoscope (a bruit is abnormal)

47
Q

Auscultate the anterior chest

A
  • Z pattern or 5 traditional valve areas.
  • Identify S1 and S2
  • Listen for possible S3 and/or S4.
  • Listen for murmurs
48
Q

5 Traditional Valve Areas:

A
  1. Aortic (R 2nd interspace)
  2. Pulmonic (L 2nd interspace)
  3. Erb’s Point (L 3rd interspace)
  4. Tricuspid (L lower sternal border, 4-5 interspace)

58
Q

Patent Ductus Arteriosus (PDA)

A

normal in fetus, spontaneously closes within hours of birth

59
Q

Atrial Septal Defect (ASD)

A

Abnormal opening of the atrial septum resulting usually in L to R shunt and causing large increase in pulmonary blood flow

60
Q

Ventricular Septal Defect (VSD)

A

Abnormal opening in septum between ventricles (usually sub aortic area)

61
Q

Tetralogy of Fallot

A

4 components: shunts a lot of venous blood directly into aorta away from pulmonary system so blood never gets oxygenated

62
Q

4 Components of Tetralogy of Fallot

A
  1. R ventricular outflow stenosis
  2. VSD
  3. R ventricular hypertrophy
  4. Overriding aorta
63
Q

Coarctation of the Aorta

A

severe narrowing of descending aorta, increased workload on L ventricle

64
Q

Mitral Regurgitation

A
  • stream of blood regurgitates back into L atria during systole through incompetent mitral valve
  • in diastole, blood passes back into L ventricle again along with new flow
65
Q

When assessing murmurs

A

determine grade, differentiate systolic vs. diastolic, note location

66
Q

Congestive Heart Failure (CHF)

A
  • the heart’s inability to pump enough blood to meet the metabolic demands of the body.
  • the kidney’s compensatory mechanisms of abnormal retention of Na and H2O to compensate for the decreased CO2
67
Q

S3

A

(ventricular gallop) occurs with heart failure and volume overload

68
Q

S4

A

(atrial gallop) occurs with CAD

69
Q

fixed split

A

unaffected by respiration; the split is always there

70
Q

paradoxical split

A

opposite of what you would expect; the sounds fuse on inspiration and split on expiration

71
Q

the murmur of mitral stenosis is

A

low

72
Q

the murmur of aortic stenosis is

A

harsh
