1

What is the fertilized ovum called when it enters the uterus? What does it do?

blastocyst;produces human gonadotropin (hCG), which stimulates the corpus luteum to continue making progesterone. It causes a small amount of bleeding when it implants to the uterine wall.

2

Talk about the placenta and what it does at certain weeks

Week 7: it supports the corpus luteum with pregnancy by producing progesterone
Week 10: completely takes over the corpus luteum by producing progesterone

3

What type of organ is the placenta? What does the placenta produce?

Endocrine organ; produces several hormones to aid in growth and maintenance of the fetus and direct changes in the woman’s body to prepare for birth and lactation

4

What does hCG do? Name four things

1. Stimulates the rise in progesterone
2. Supports the corpus luteum
3. Supports deep implantation of the placenta into the uterine wall
4. Helps maintain viability of the fetus

5

What does progesterone do? Name three things

Maintains the endometrium around the fetus
Increases the alveoli in the breast
Keeps the uterus in a quiescent (inactive) state

6

What does estrogen do?

Stimulates the duct formation in the breasts, increases the weight of the uterus, and increases certain receptors in the uterus that are important at birth.

7

How long does pregnancy last?

280 days from the first day of the last menstrual period (LMP)
(40weeks), 10 lunar months/9calendar months

8

Why does pregnancy include 9 calendar months but 10 lunar months?

The 10 lunar months include the 2weeks when the follicle was maturing but before conception actually occurred.

25

When is quickening felt?

18-20wks

26

Talk about colostrum

The precursor of milk that may be discharged from the nipples during pregnancy. Yellow color and contains more minerals and protein, but less sugar and fat than mature milk. It also contains antibodies which are protective for the newborn during the first days of life until mature milk production begins.

27

5-15mmHg lower (diastolic)
The most pronounced drop is at 20weeks; may cause dizziness, faintness

28

What do a woman’s insides start to do during the second trimester?

Stomach displacement from enlarging uterus, altered esophageal sphincter and gastric bone (may cause heartburn), intestines are displaced by growing uterus, tone and mobility are decreased (constipation), gallstones may form from bile stasis and increased cholesterol

29

Talk about the respiratory system during pregnancy

Progesterone and estrogen cause increased respiratory effort by increasing tidal volume. HgB also increase with oxygen capacity increase, drop in PaCO2 (may cause dyspnea)

35

What does uterine enlargement do to the mama in the third trimester?

Causes the diaphragm to rise and the shape of the rib cage to widen at the base. Decreased space for lung expansion may cause SOB, the rising diaphragm displaces the heart up and to the left. CO, SV increase, pulse raises by 15-20bpm, a functional systolic murmur may be heard (grade 2/6 or less)

Premature ROM, preterm labor (PTL), preterm delivery (PTD), postpartum maternal and fetal infections, herpes in babies

62

Why must HIV screening be OFFERED to mamas? Can an HIV mama breastfeed?

Must be offered to decrease the risk of transmission to the fetus.
Breastfeeding in contraindicated for HIV-positive mother because the virus is in the breast milk

63

Why should you ask a woman her sexual preference?

Woman with same-sex partners may use assisted reproduction, they need your support.

64

What is a VBAC?

Vaginal birth after c-section

65

Talk about the risks certain c-section incisions may place on a mama who is pregnant again.

Vertical/classical incision: increased risk for rupture and mandates another c-section
Low transverse/horizontal incision: carries a low risk, subsequent births can be vaginal
The direction of the skin scar doesn’t necessarily tell you how the uterus was cut

66

What might vaginal bleeding indicate during pregnancy?

Threatened abortion, cervicitis, or ectopic pregnancy in 1st trimester. A friable cervix May bleed harmlessly after sex and not hurt the fetus

67

What may abdominal pain indicate in pregnancy?

Abdominal pain during early pregnancy may indicate spontaneous abortion, ectopic pregnancy, UTI, and round ligament discomfort. Late pregnancy causes are premature labor, placental abruption, and HELLP syndrome

68

When should a woman start counting fetal movements

3rd trimester

69

Why would you want to know if a mama previously had German measles/rubella?

It is highly teratogenic, especially in the first trimester. Instruct the woman who has not had rubella to avoid small children who are ill

70

Why would you ask a mama if she’s ever had chicken pox?

Rarely varicella causes congenital anomalies. Nonimmune women should avoid exposure

Preeclampsia

76

If a mom is already diabetic, what is she at risk for?

Ask her to empty her bladder, reserving a clean-catch specimen for dipping for protein and glucose and for urinalysis. Weigh her on the scale, compute the BMI, give her a gown and drape

84

How should you check the pregnant woman’s BP? At which angle should the mom be in bed during the 2nd and 3rd trimester and why?

BP while sitting
30-45 degree angle in 2nd and 3rd trimesters to increase comfort and avoid compression of the descending aorta and inferior vena cava by the pregnant uterus

85

What is a healthy BMI?

19-25. A weight loss of more than 5% during the first trimester is not good: hyperemesis gravidarum?

86

What is chloasma?

“Mask of pregnancy”
Butterfly-shaped pigmentation of the face

87

Where does linea nigra start/end? What is striae like during and after pregnancy?

Linea nigra starts at the bottom of the sternum and goes to the pubis.
Striae are bright red when they first form, but shrink, lighten, and turn to a silvery color after pregnancy

88

Talk about PUPPP

Pruritic urticarial papules and plaques of pregnancy!!
The most common itchy rash of pregnancy. More common in white, nulliparous women. Appears in late pregnancy in abdomen and thighs. Incidence is 1 in 200 pregnancies, but increases to 8 in 200 with multiple fetuses

Auscultation of the translucent blood vessels in the breast can be heard and may be mistaken for a heart murmur

92

What if a woman’s nipples are inverted or flattened? What are the bumps around the nipple called?

Flat/inverted nipples can be fixed with latch-on techniques or during pregnancy.
Montgomery’s tubercles

93

How should the breast tissue feel on palpation

Modular with alveoli hypertrophy. Teach mama to do self-exams (BSE) because lack of menses. Note any abnormal mass and refer for US

94

Where should you ausculate the heart in a pregnant woman and what might you hear?

4th intercostal space r/t growing fetus. She often has a functional, soft, blowing systolic murmur that occurs r/t increased volume. It requires no treatment and will resolve after pregnancy. Any other murmur should be refereed as prophylactics for valvular disease may be needed at delivery

95

Talk about edema in a pregnant lady

Edema with increased BP and proteinuria may indicate preeclampsia. Edema and pain in one leg occur with DVT and warrant Doppler studies. Carefully evaluate any redness, swelling, or hotness to r/o phlebitis. Should wear support hose and not wear restrictive clothing or sit for too long

96

What is it called when the abdominal muscles normally separate when the woman lifts her head?

Diastasis recti

97

On which side should you stand facing the pregnant ma whenpalpating her fundus?

Right side, aim higher than where you think the fundus is. Walk your hands until you feel it

98

After which week in pregnancy can you start measuring the fundus in which 1cm = 1wk gestation? What if the growth is below normal? What about above?

20weeks.
Fundal height more than two cm less than what it should be can indicate intrauterine growth restriction
Fundal height more than 4cm more than what it should be can indicate multiple babies, excess amniotic fluid, or uterine myoma.
Both indicate need for ultrasound

99

When can you start Leopolds maneuvers? What does it determine? Explain these things

3rd trimester
Fetal lie: orientation of the fetal spine to the maternal spine (longitudinal, transverse, or oblique)
Presentation: the part of the fetus that enters the pelvis first (vertex=head, breech, foot)
Attitude: the position of the fetal parts in relation to each other (flexed, straight/military, extended)
Position: location of fetal part R or L of maternal pelvis
Engagement: widest diameter of the presenting part is descended into the pelvic inlet

100

Describe the leopolds first maneuver

Face the gravida’s head and place your fingertips around the top of the fundus. Note size, consistency and shape. Butt will feel soft, head will feel hard, ballotting/bobbing willl occur because the head moves easily

101

What is leopolds second maneuver?

Move your hands to the side of the uterus. The long, firm surface is the back, and the small parts (limbs) indicate a posterior position when they are palpable all over the abdomen. Note if the position is lateral, posterior (out of reach) or anterior.

102

What is leopolds third maneuver?

“Pawlik’s maneuver” ask the woman to Bend her knees up slightly. Grasp the lower abdomen just above the pubis and on top the fundus to determine the presenting part of the fetus. If the presenting part is beginning to engage, it will feel fixed

103

Describe leopolds fourth maneuver

It help determine engagement and differentiate shoulder from vertex. With her knees bent, face the mom’s feet, place your palms with fingers facing the feet on either side of the lower abdomen. Press your fingers firmly and slowly down toward the pelvis. If your fingers meet, the presenting part is not engaged. If your fingers diverge at the pelvis meeting a prominence on one side, the prominence is the head. If your fingers meet prominences on both side, the vertex is engaged as military or flexed.

104

How do obtain the fetal heart rate using the Doppler? What should be the normal rate. Talk about normals/abnormals

Count the FHTs for 6seconds and multiply by 10. Normal rate should be 110-160bpm. Spontaneous accelerations indicate fetal well-being. If no FHT is heard with Doppler at 12 wks, indicate fetal activity with ultrasound. Further investigate HR that are too low/high. Feel the mothers pulse while listening so you dont mistake a FHT with a uterine soufflé

105

Talk about the external genital findings that may be present in a pregnant woman

Labia Minora may be enlarged in multiparous women. Labial variscosities may be present. The perineum may be scarred from previous episiotomies or lacerations. Note any hemorrhoids or lesions. Lesions may indicate infection: herpes or chlamydia

106

What is the Chadwick’s sign

Bluish, purplish discoloration and congested look of the vag wall and cervix from increased vascularity and engorgement.

107

Talk about pregnant vaginal discharge

Should be heavier in amount, but should be similar in description to the nonpregnant woman. No itching, burning, unusual odor, or purulent drainage should be present. Perform a wet mount/culture if uncertain. Chapping may be found normally r/t excessive moisture

108

How should. The cervix look in a pregnant lady

Smooth, round with a dot like external os of the nulliparous mama or the irregular multiparous cervix with and external os that appears more like a crooked line, the result of cervical dilation from prev. Pregnancy. A friable cervix bleeds easily when touched with a cotton swab, cytobrush or speculum r/t increased vascularity. Obtain cultures if you suspect cervicitis

109

What is dextrorotation?

The pregnant uterus may be rotated toward the right side as it rises out of the pelvis because of the presence of the descending colon on the left.

110

What is the Hegar sign?

When the enlarged uterus bends forward on its softened isthmus between the 4th and 6th weeks of pregnancy

111

Talk about uterine size

Size of an avocado by 8wks (7-8cm)
10weeks: grapefruit
12week: will fill the pelvis

112

What is the Goodell sign

Softening of the cervix

113

What are leiomyomas

Uterine fibroids (abnormal finding)

114

What should you assess with the cervix?

Position (anterior, midposition, posterior)
Degree of effacement/thinning (%)
Dilation (cm)
Consistency: firm/soft
Station of presenting part (cm above/below ischial spine)

115

What does a shortened cervix indicate?

Less than 2cm= preterm labor or possible cervical insufficiency

116

Talk about the ovaries during pregnancy

They rise with the growing uterus. Always examine the adnexa to r/o mass (ectopic pregnancy/ovarian mass). To determine tone, ask her to squeeze your fingers as yours rest in her vag. (Practicing Kegel exercises). Squeeeze for 8, release for 8. Perform 50-100x/day

117

When should you take the mama’s bp? What would be considered chronic HTN

When she is most relaxed.
Chronic HTN: a documented stage one HTN before pregnancy or a persistent elevation of more than 140/90 on two occasions more than a day apart before the 20th week gestation

118

What is the ultrasound most helpful for?

Showing the age of fetus, placenta location, fetal position, sex of fetus, number of babes, and certain birth defects.

119

When should cervical length be measured. What does it predict

18-22weeks. Measures to predict preterm labor

120

Talk about fetal macrosomia

A condition in which the infants weight is beyond 4000-4500g, regardless of gestational age. Occurs in less than 9% of tykes. Risk factors include obesity, diabetes, post term gestation, advanced mama age, prev. Chubby babies, racial/ethnic factors. Birth risks to mama =bladder trauma, and vagincal tissue trauma. Baby might have broken clavicle, brachial plexus nerve damage, bad APGAR scores, extended hospitalizations, and possible fetal mortality

121

What factors cause maternal preeclampsia?

Placenta implanted with abnormal trophoblastic invasion, immunologic intolerance, cardiovascular/ inflammatory changes, genetic factors

Previous preeclampsia, multifetal gestation, chronic HTN, obesity, 35 yo or more, and African Americans

122

What is preeclampsia characterized by

HTN and proteinuria.
Headaches, visual changes r/t cerebral edema, RUQ pain from liver enlargement

123

What would preeclampsia labs be like?

Elevated liver enzymes, increased hematocrit, platelet drop, increased in BUN/creatinine
(HELLP syndrome: hemolysis, elevated liver enzymes, and low platelets.....a serious variant of preeclampsia)

124

How can preeclampsia harm the fetus

Before it become clinically manifested, it affects the placenta thru vasospasm and a series of small infarctions. The capacity of the placenta to deliver oxygen and nutrients may be seriously diminished and fetal growth may be restricted.

125

What happens if preeclampsia goes untreated

Tonic-clinic seizures. Eclampsia may develop as late as 10days postpartum.
