25
Q

Viability

A
  • capacity to live outside uterus- 22 to 24 weeks OR- fetal weight > 500g (approx 1lb)
26
Q

physiologic anemia

A

hemodilution due to plasma increase > RBC increase in pregnant woman;- decreased hgb- decreased hct

27
Q

hyperplasia

A

increase in number of cells (formation of new tissue)

28
Q

hypertrophy

A

enlargement of existing cells

29
Q

stroke volume

A

volume out of left ventricle, each heart beat

30
Q

cardiac output

A

CO = HR x SVfunctional capacity of LV to maintain BP and organ perfusion

31
Q

vena caval syndrome

A

during pregnancy, when vena cava squashed and venous return impeded

32
Q

trend: stroke volume during pregnancy

A

increases

33

Q

systolic blood pressure

A

pressure generated by LV to push blood into aorta during contractions- remains relatively the same during pregnancy

37
Q

diastolic blood pressure

A

pressure against arterial walls during heart relaxation- decreases slightly during pregnancy

38
Q

systemic vascular resistance

A

resistance of blood flow through body vessels, increases when vessels constrict and decreases when vessels dilate

39
Q

tidal volume

A

normal volume of air displaced (inspired before expiration)

40

glycosuria during pregnancy

A

COMMON. increased amount of glucose filtration (exceeds reabsorption capacity); doesn’t reflect abnormal carb metab

46
Q

urinary stasis

A

larger volume of urine held in pelvis, ureters- stagnating urine + increased glucose (pH increase) = more susceptible to UTIs
