2nd trimester
64
How should a nurse take a maternal blood pressure?
- brachial BP highest sitting, lowest lateral recumbent, intermediate supine.
65
BP is never elevated above normal levels unless ___.
PIH (pregnancy induced HTN)
66
What is an intervention a nurse can perform to reduce mother's BP?
Turn on left side
67
What is Supine Hypotensive Syndrome?
SBP falls more than 30mm/Hg suddenly.
68
What usually causes Supine Hypotensive Syndrome?
Usually from lying on back and compressing vena cava.
69
What does an enlarging fetus rests on iliac veins & inferior vena cava do?
increased venous pressure & decreased blood flow to legs.
70
What do the findings of an increased venous pressure & decreased blood flow to legs.
These findings contribute to dependent edema of legs, varicosities of legs & vulva, & hemorrhoids.
71
What does the blood volume increase to?
1500 mL
72
What does the increased blood volume serve?
volume serves to supply uterus & fetus with O2 & provides extra fluid volume at delivery for potential blood losses.
73
When is a pregnant woman considered anemic?
If Hgb 11 g/dl or less or Hct drops to 32% or less woman considered truly anemic.
74
What is significant about clotting factors in pregnant women?
Clotting factors increase during higher risk for blood clots.
75
What does fibrinolytic activity do during pregnancy?
depressed as a protective mechanism – helps prevention of hemorrhage after birth = increases risk of thrombus formation.

How can renal function be improved?
Renal function improves if lying in lateral recumbent position d/t increased renal perfusion = increased urinary output & decreased edema.

What drug should pregnant women avoid?

86
What can diuretics cause in pregnant women?
risk of hypovolemia & altered tissue perfusion.

97
The best technique to manage epulis is…
Soft toothbrush
98
What is significant about spinal curvature (lordosis)?
increases in late pregnancy - forward shift in center of gravity secondary to large abdomen.

causes muscle cramps or tetany
100

107
What does progesterone do to GI?
