A measurement from the top of the fundus to the symphysis pubis as measured in centimeters.

It estimates the gestational age.

23
Complete the sentence:

After week 18, the fundal height in centimeters = number of    ______ pregnant. 

After week 18, the fundal height in centimeters = number of weeks pregnant. 

24

The fundal height and gestational age of fetus can be off by how many centimeters? 

Fundal height and gestational age can be off by plus or minus 2 centimeters.

Ex: a fundal height of 20 cm can indicate that the fetus is somewhere between 18 and 22 weeks old.

25

What are the physical and psychological changes in pregnancy caused by?

Changes are caused by hormones.

26

What cardiovascular changes does a pregnant woman go through?

  • lower than normal hemoglobin and hematocrit

Changes are due to increased blood volume.

27

What hemoglobin and hematocrit levels is considered anemia in a pregnant client?

Hematocrit < 30% and Hemoglobin < 10 is considered anemia in a pregnant client.

Pregnant clients have a slightly lower hemoglobin and hematocrit due to increased fluid volume.

28

How high does the heart rate of the pregnant woman increase due to increased blood volume during pregnancy?

A pregnant woman's heart rate increases 10-15 beats per minute from the baseline.

A non-invasive test that checks the fetus. It includes:

  • ultrasound
  • non-stress test

 

48

What is a nonstress test?

A nonstress test is a non-invasive test of the fetus to check fetal heart rate patterns. 

The pregnant client lies down with two belts around her waist. One belt measures the fetal heartbeat and the other measures contractions. It takes about 20 minutes. 

49

What is a reactive nonstress test?

A reactive nonstress test is a normal finding and that the fetal heart rate went up normally. It indicates that the fetal heart rate is "reassuring":

  • fetal heart rate increases at least 15 beats per minute over the baseline (between 120 and 160 beats per minute)
  • The increase in heart rate lasts at least 15 seconds within a 20-minute timeframe

 

50

What is a NON-reactive nonstress test?

A NON-reactive nonstress test is an abnormal finding and that the fetal heart rate did not increase enough. It indicates more testing is needed. 

It can also indicate that the fetus was sleeping.

 

51

What is an amniocentesis?

An amniocentesis tests the amniotic fluid for genetic disorders and fetal lung maturity.

A needle is used to aspirate a small amount of amniotic fluid through the pregnant client's abdomen guided by ultrasound. 

 

 

52

What are the interventions before and after an amniocentesis?

  1. before procedure - get informed consent
  2. after procedure - assess for signs of complications
    • bleeding, infection, decreased fetal movement, and cramping

53

What is quickening in pregnancy?

Quickening is the moment when the pregnant woman starts to feel or perceive fetal movements in the uterus.

It usually occurs between week 15 and 25. About 50% of women don't feel anything until after 24 weeks gestation.

54

What is a kick count test?

A kick count test is when the pregnant client counts the number of kicks by the fetus in a 2-hour period. 

Notify the HCP if there are < 10 kicks in two consecutive 2-hour periods.

55

What is a fern test?

A fern test identifies the presence of an amniotic fluid leak. 

It will make a fernlike pattern on a microscopic slide.

56

What is a nitrazine test?

A nitrazine test identifies the presence of amniotic fluid in vaginal secretions by putting a drop of fluid on a paper strip.

It will turn the paper blue if there is amniotic fluid.

57

What is a contraction stress test?

A contraction stress test is performed at the end of pregnancy to determine how well the fetus will cope with the contractions of childbirth.

Contractions are induced by administering oxytocin (or nipple stimulation) and the contractions and heart rate of the fetus is recorded.

 

58
Immediate complication

What is a positive/abnormal contraction stress test?

A positive/abnormal result indicates a bad finding and that late decelerations of the fetal heart rate were noted.

Late decelerations are never a good finding.

59

For miscarriage or abortion, hemorrhage is:

  • > 1 saturated pad/hour
  • one pad that gets saturated within 15 minutes

61

What are the insulin needs for a pregnant client with diabetes mellitus?

During 2nd and 3rd trimester pregnant client needs more insulin

The hormones in the placenta block insulin. 

62
Describe:
