Threatened - Increased chance to lose pregnancy
Inevitable - Cannot be stopped

Missed - Fetus dies in 1st trimester and is still in the uterus
Complete - All products of conception have passed
Reccurent - 2 or more spontaneous

3

Difference between threatened and inevitable abortion

In a threatened abortion, the membranes are intact and cervix is not opening

4

Intervention for Threatened Abortion

Bed rest for 24 hours, still allowed to get up, but should limit activity. No sexual activity and count pads

5

Inevitable abortion intervention when fetus is not expelled

Vacuum curretage in the early weeks or Dilation and curretage in the late weeks

6

Missed abortion characteristic

Uterus stops growing and dark brown bleeding. also at risk for Disemminated intravascular clot

7

Gestational Trophoblastic Disease

Uterus not compatible with life. Increased HCG levels and managed by removing tissue with vaccuum.

8

Hyperemesis Gravidarum

Persistent, uncontrolled vomiting

9

Placenta Previa
Marginal
Partial
Total

Placenta implanting in the lower part of the uterus.
Marginal - Barely extends to cervical os (does not cover)
Partial - Does not fully cover cervical os
Total - Fully covers cervical os
TOTAL/PARTIAL REQUIRES C-SECTION

10

Gestational Hypertension

BP 140/90 without proteinuria

11

Drug of choice for Preeclampsia

Magnesium Sulfate (CNS depressant), reduces seizures and BP. ALWAYS PIGGYBACK and hourly assessments (especially BP and RR).

12

Labor - Tight glycemic control
Postpartum - Rapid decrease. Need to monitor

17

Glucose Challenge test

done at 24-26 weeks, takes 1 hour, >140 mg/dl indicates further testing (they do a 3hr glucose tolerance test)

18

Oral glucose tolerance test

3 hour test, gold standard that determines diet and insulin needs.

19

Cardiac disease Class

Class I - Unrestricted activity
Class II - Slightly restricted activity, activity causes PAFD (palpitations, angina, fatigue, dyspnea)
Class III - Moderately restricted activity, activity causes palpitation, angina, fatigue, dyspnea
Class IV - Discomfort with all activity, activity causes angina and cardiac insufficiency at rest.

20

What is megaloblastic anemia

Folic acid deficiency

21

Antiphospholipid disease

Recurrent arterial/venous clots and decreased platelets

22

What is Cytomegalovirus' effect and transmission?

Transmitted through breast milk and causes deafness, blindness, mental retardation and seizures.

23

What is Rubella's effect and transmission?

Transmitted through placenta and causes deafness, retardation, cardiac defects, and microcephaly.

24

Varicella transmission and effect?

Transmitted Direct, Respiratory tract, and through placenta. Causes limb hypoplasia, scars, cataracts, and microcephaly. Baby is protected ONLY if baby is born 6 days before the mother develops varicella as maternal antibodies protect the fetus. If

25
