Flashcards in Lecture 08 High Risk Pregnancy and Compliation During Labor and Delivery Deck (60):
1

What are some causes of early pregnancy bleeding? (3)

1. Miscarriage: spontaneous abortion (SAB)

2. Incompetent cervix

3. Hydatidiform mole (molar pregnancy)

2

Late pregnancy bleeding causes (2)

1. Placenta previa 2. Placenta abruption

3

There are dif levels of miscarriage (SAB): Def each: Threatened:
Inevitable:

Threatened: slight bleeding with cramping

Inevitable: heavy bleeding with increased cramping. Cervical dilation and ROM>imminent

4

There are dif levels of miscarriage (SAB): Def each: Incomplete (rather common): Complete:

Incomplete: retained placental tissue in uterine cavity. But continued bleeding until complete removal of all placental tissue
Complete: Uterus evacuates all products of conception

5

There are dif levels of miscarriage (SAB): Def each: Missed spontaneous abortion

embryo/fetus has expired, however the contents of conception remain in the uterus.

6

How would miscarriages be assessed? (3)

U/S Beta hCG levels VS

7

What is an incompetent cervix?

Passive or painless dilation of the cervix during the 2nd trimester.

8

How do you assess for incompetent cervix?

1. funneling of the cervix 2. Shortening of the cervix

9

What is a medical management of cervix?

Placement of a cerclage, a big and thick stitch

10

What is a hydatidiform mole?

aka Gestational Trophoblastic disease, it's rapidly dividing cells with no genetic material from the ovum. Occurs in the uterus. So sperm and egg come together, but doesn't develop into fetus, but into rapid placental pos cancerous tissue. Occurs more in teenagers vs women Etiology unknown.

11

Who are at risk of hydatidiform mole?

1. Use of clomid: med to help women ovulate 2. teenagers and women >40 are at risk

12

Nursing implications of hydatidiform mole

1. U/S, beta hCG levels 2. Suction curettage, want to make sure you get all the cells out 3. Induction of labor is contraindicated 4. Admin rhogram is indicated 5. Education: pregnancy should be avoided for one year

13

What is placenta previa?

Placenta implanted over the lower uterine segment or over cervical os

14

What are sx of placenta previa?

1. painless bright red vaginal bleeding 2. Associated with stretching and thinning of the uterine 3. Abdomen will be soft, nontender and relaxed 4. Fundal height is usually greater than expected. The fetus is un able to settle into the pelvis related to low lying placenta

15

What is Dx of placenta previa?

U/S

16

What are nursing care for placenta previa?

1. Stable: expectant management (no vaginal exams) 2. Unstable ~ delivery by cesarean section

17

What is placenta abruption?

Detachment of part or all of the placenta from its implantation

18

What are risks that may cause placenta abruption?

1. maternal HTN 2. PSA, mainly stimulates (cocaine), causes vasoconstriction 3. Abdominal trauma, may want to ask mother if she was abused by her partner 4. Smoking

19

What are sx of placenta abruption?

1. painful bright red vaginal bleeding 2. uterine contractions 3. Uterine tenderness 4. lab tests: Kleihauer-betke stain (KB) : Determines the presence of fetal to maternal bleeding If present and mom is RH - , Rhogam is given Hemoglobin or Hematocrit (to see if blood is dropping) Clotting studies

20

What are nursing care steps for placenta abruption?

If stable: expectant management If unstable: move towards delivery either vaginal or c/s

38

Sx of Preeclampsia/HELLP

  1. •Decreased perfusion to eyes = visual changes, headaches
  2. •Decreased liver perfusion causes epigastic pain
  3. •Decreased renal perfusion causes oliguria may result in renal failure
  4. •CNS irritability = Increase in DTR’s, clonus, hyperreflexia & convulsions
  5. •Pulmonary edema related to chronic heart failure which can result if BP is unable to be controlled
  6. •Pitting edema, Facial edema- associated with increased risk of neurologic involvement

•HELLP

§Vasospasm continues to increase resulting in tissue hypoxia

  6. —Ketoacidosis
  7. —Increased AF, cuz baby is peeing a lot

45

Why does diabetes occur during pregnancy?

—Pathyphysiology due to hormones made by placenta, protein: Human placenta lactogen

—Altered glucose metabolism occurs during pregnancy to ensure adequate fetal nutrition

—Glucose is the primary fuel for the fetus and crosses the placenta

—Insulin does not cross the placenta, the fetus excretes it own insulin in respect to maternal glucose

—During the second trimester a “dibetogenic” effect occurs: results in decreased tolerance to glucose stores, increased insulin resistance, decrease in glycogen stores and  increased production of glucose

—Resulting in maternal insulin requirements increasing from 20 weeks to 36 weeks gestation

—Remember babies born to diabetic moms are hypoglycemic at birth

46

What are some nursing implications for diabetes during pregnancy?

  1. —Education:   nutritional counseling, weight gain recommendations!
  2. —Greater risk for
    —Birth trauma related to macrosomia
    —Congenital malformation
    Delayed pulmonary maturation in newborn
    —Increased risk of glucose intolerance in mother later in life
    Increased risk of HTN while pregnant

47

What are some screening techniques for diabetes during pregnancy?

  1. —Urine dip at every prenatal visit
  2. —CBG at every prenatal visit
  3. —Glucose tolerance test (GTT), Three hour GTT.
  4. —Hemoglobin A1C to determine long term glucose control
  5. Results has to be less than 135. If it’s not, then woman will have to come in for another test while she’s fasting. It’s harder, since it’s 3~5 hours
