    It is a hormone secreting body that releases estrogen and progesterone for the first 6-8 weeks, which is due to the hCG.

    It will regress after 20 weeks as the placenta gradually takes over production of the estrogen and progesterone.

  71. This term occurs around 40 weeks, when the fetal head descends into the pelvic cavity and the uterus sinks to a lower level. 

    How will it help make the mom feel better?
    Lightening: it reduces pressure on the diaphragm and makes breathing easier.

    • b. Hyperemia
  74. How does estrogen and progesterone affect plasma volume levels?
    Plasma volume increases from 6-8 weeks by an increase of 40-60% (1200-1600mL). Estrogen and progesterone stimulate the renin - angiotensin - aldosterone system, which stimulate Na and water retention.
  75. Fill in: Generally, iron deficiency anemia occurs when the hemoglobin is less than __a__ g/dL or the hematocrit is less than __b__% in the first or third trimester.
    • a. 11g/dL
    • b. 33%
  76. How does supine hypotension occur?
    When the mom is supine, the weight of the gravid uterus can occlude the vena cava and aorta, which impedes return of blood and cardiac output.

    • Can increase up to 25-30,000 during labor.

    How can you offer some relief?
    Pytalism: small, frequent meals, gum chewing, and oral lozenges
  81. T or F: The mother during pregnancy will have an increased motility of the large intestines, which can lead to diarrhea.
    False: decreased motility which allows time for more water to be absorbed, leading to constipation.
  82. How does progesterone effect the  gallbladder?
    Gallbladder: becomes hypotonic and emptying time is prolonged, resulting in thicker bile, predisposing to gallstones, as well as itching.
  83. How is the liver affected during pregnancy?
    In the last trimester, the liver is pushed upward and backward by the enlarging uterus.

    Serum alkaline phosphatase rises 2-4x, and serum albumin and total protein fall.
  84. T or F: Nocturia is common during pregnancy
  85. T or F: Progesterone causes the kidneys and ureters to dilate
    True: ureters become elongated and more distensible. 

    Also, the ureters are compressed d/t the enlarging uterus, which causes stasis of urine, allowing time for bacterial build up.
  86. This line is a longitudinal mark of the midline of the abdomen, which can eventually darken. It occurs from increased pigmentation from elevated estrogen, progesterone, and melanocyte hormones.

    It can also cause brownish patches over the forehead, cheeks, and nose, called this...
    Linea nigra

    Melasma, chloasma, or the "mask of pregnancy
  87. During pregnancy, will FSH and LH increase or decrease?
    They will be suppressed, because they are not needed to stimulate ovulation during pregnancy.
  88. This hormone will stimulate milk-ejection, and also stimulate contractions of the uterus.
  89. Will progesterone levels increase or decrease after childbirth?
    Decrease: they will decline when the placenta is removed, and oxytocin will increase to keep the uterus contracted, preventing excessive bleeding. 

    (During pregnancy, progesterone will relax the smooth muscles of the uterus)
  90. Why does tissue sensitivity to insulin decline during pregnancy?
    During second half of pregnancy, tissue sensitivity of insulin decline because of HCS, prolactin, progesterone, estrogen, and cortisol all fluctuate. This causes the mother to use fat stores to meet energy demands, causing higher blood glucose levels, which then stimulate the pancreas to produce additional insulin. 

    Inadequate insulin production results in gestational diabetes.
  91. This hormone causes the corpus luteum to produce progesterone and estrogen until the placenta is sufficient enough to take over (at 10-12 weeks).
  92. List the major functions of progesterone (8)
    • 1. maintain endometrial layer for implantation of fertilized ovum
    • 2. Preventing spontaneous abortion by relaxing smooth muscle of uterus
    • 3. Prevent tissue rejection of fetus
    • 4. Stimulate development of lobes and lobules in breast for lactation
    • 5. Faciliate deposit of maternal fat stores, for energy reserve
    • 6. Smooth muscle relaxer
    • 7. Increase respiratory sensitivity to CO2, for ventilation
    • 8. Suppressing the immunologic response, prevecnting rejection of fetus.
  93. What is the purpose of hCS (Human Chorionic somatomammotropin)
    1. Increase the availability of glucose for the fetus. It is an insulin antagonist, reducing the sensitivity of maternal cells to insulin. This will increase free blood glucose.

    It also promotes mobilization and use of free fatty acids to provide energy for pregnant women.
  94. This hormone is produced by the corpus luteum, decidua, and placenta. Its purpose is to inhibit uterine activity, soften connective tissue in cervix, and lengthen pubic ligaments.
