- What is lightning?
- Between 38-40 weeks the fetus begins to descend and engage in the pelvis. This may occur in nullipara, approximately 2 weeks prior to the onset of labor and at the start of a multiple labor.
- What is commonly used to estimate the the duration of pregnancy?
- Fundal height. There are variations depending on the amount of amniotic fluid, presence of more than one fetus, obesity, and even a variation depending on the examiner.
- What type of contractions can be felt during the fourth month?
- Uterine contactions can be felt through the uterine wall. This is commonly called Braxton-Hicks contractions, which are painless contractions that occur intermittenly throughout the pregnancy.
- What is the purpose of Braxton-Hicks contractions?
- They facilitate uterine blood flow through the intervillous spaces of the placenta and promote oxygen delivery to the fetus.
- What does uteroplacental blood flow depend on?
- Depends on the maternal blood flow to the uterus. It increases rapidly as the uterus increases in size (20X). The fetoplacental unit grows even more rapidly.

Increase vascularity causes a violet - blue coloring of the vaginal mucosa = Chadwick's. 6-8th week. Probable sign of pregnancy.
- White or slightly gray mucoid discharge. Response to cervical stimulation by estrogen and progesterone. The fluid is whitish due to the presence of many exfoliated epithelia cells normal in pregnancy.
- Why is the pH more acidic during pregnancy?
- This is a result of increased production of lactic acid caused by Lactobacilus acidophilis. Acting on the glycogen in the vaginal epithelium.

- urine output/dip
- epigastric pain
What needs to be watched with proteinuria?
- the liver and kidneys
- In an adult, a normal count is about 150,000 to 450,000 platelets per microliter (x 10–6/Liter) of blood.
If platelet levels fall below 20,000 per microliter, spontaneous bleeding may occur and is considered a life-threatening risk.
Up to 5% of pregnant women may experience thrombocytopenia at term.
- a rare but serious illness in pregnancy. This illness can start quickly, most often in the last 3 months of pregnancy (the third trimester). It can also start soon after you have your baby. HELLP stands for Hemolysis, Elevated Liver enzyme levels and a Low Platelet count. These are problems that can occur in women with this syndrome.
Women with HELLP syndrome may have bleeding problems, liver problems and blood pressure problems that can hurt both the mother and the baby.
- the breaking open of red blood cells and the release of hemoglobin into the surrounding fluid
What are some complications of HELLP?
- DIC, abruptio placentae, renal failure, pulmonary edema, ruptured liver hematoma
What condition can occur after severe preeclampsia?
- eclampsia or HELLP
Nursing care for mild preeclampsia
- - bed rest
- BP monitoring from home
- daily wt measurement & urine dipsticks
- fetal movement counts
- NST 1-2x/week
Biophysical profile (BPP)
- A biophysical profile (BPP) test measures the health of your baby (fetus) during pregnancy. A BPP test may include a nonstress test with electronic fetal heart monitoring and a fetal ultrasound. The BPP measures your baby's heart rate, muscle tone, movement, breathing, and the amount of amniotic fluid around your baby.
A BPP is commonly done in the last trimester of pregnancy. If you have a high-risk pregnancy, a BPP may be done by 32 to 34 weeks or earlier. Some women with high-risk pregnancies may have a BPP test every week or twice a week in the third trimester.
What is the drug of choice for the prevention of seizures caused by preeclampsia and eclampsia?
- Magnesium Sulfate
How is Magnesium Sulfate administered?
- Initial IV bolus given, then maintenance dose (piggyback).
Only given on a pump.
What is the therapeutic serum level for magnesium sulfate?
What is the antidote for magnesium sulfate overdose?
- calcium gluconate
How long after birth do you infuse magnesium sulfate?
- 12-24 hrs
Signs and symptoms of magnesium sulfate toxicity
- - resp <12/min
- hyporeflexia, lack of reflexes
- urine output <30 ml/hr
- toxic serum levels >9.6 mg/dl
What is hyperemesis gravidarum?
- unrelenting, excessive pregnancy-related nausea and/or vomiting that prevents adequate intake of food and fluids." It is considered a rare complication of pregnancy.
What does hyperemesis gravidarum lead to?
- dehydration, weight loss, electrolyte imbalance, ketosis, acetonuria
- the loss of a fetus during pregnancy due to natural causes.
- The spontaneous termination of a pregnancy before fetal development has reached 20 weeks. 12-25% of all pregnancies. 80-90% happen before 12th week and are a result of chromosome abnormality.
What does AMA mean?
- advanced maternal age
What are pregnancy losses after the 20th week categorized as?
- preterm deliveries
- the development of symptoms (bleeding with or without cramps or low back pain) that often suggest impending miscarriage. With such a presentation of bleeding, 50% proceed to miscarriage of the pregnancy.
- The miscarriage of a pregnancy is inevitable when any of the following symptoms are present:
- There is an obvious rupture of membranes
- An open cervix
- There is tissue in the cervix
- There is an absence of fetal heart at a βHCG level consistent with fetal heart activity
When any of these symptoms are detected, management involves conservative observation, monitoring for heavy bleeding and sepsis, and a dilatation and curettage (D&C).
- An incomplete abortion is the miscarriage of a fetus in a pregnancy when tissue has been passed, but some remains in utero. It can result in severe bleeding, infection or intrauterine scarring. Management consists of a dilation and curettage (D&C).
- A missed abortion is the miscarriage of a fetus in a pregnancy when the fetus has died, but remains in the uterus. The condition is also referred to as "delayed miscarriage". Many cases of missed abortion will lead to a spontaneous abortion within two weeks. Occasionally, a dilatation and currettage is necessary to remove the pregnancy tissue, done in reponse to the risk of maternal coagulation abnormality if the tissue remains in the uterus for several weeks.
What is an ectopic pregnancy? How are they classified?
- Fertilized ovum implants outside of the uterus. They are classified by location.
What are the s/s of ectopic pregnancy?
- Unilateral pain, vaginal spotting or bleeding (red or brown) and + pregnancy test.
What is the treatment for ectopic pregnancy?
- Methotrexate (3.5cm or smaller) or surgery.
What is Gestational trophoblastic disease (GTD)?
- It is actually a group of several diseases -- all involve abnormal growth of cells inside a woman's uterus. But unlike cervical cancer or endometrial (uterine lining) cancer, GTD does not develop from cells of the uterus. These rare, once fatal, but now highly curable tumors start in the tissue that begins to develop immediately after conception, when sperm from the father fertilizes an egg from the mother.
What are the two types of hydatidiform moles?
- complete hydatidiform moles and partial hydatidiform moles
complete hydatidiform mole
- develops mainly because a sperm has fertilized an “empty” egg (contains no nucleus or DNA). All the genetic material comes from the father’s sperm. Therefore, there is no fetal tissue. Up to 20% of patients with complete moles will need additional surgery or chemotherapy after their initial surgery. A small percentage of complete moles may develop into choriocarcinoma, a malignant form of GTD.
partial hydatidiform mole
- develops when two sperm fertilize a normal egg. These contain some fetal tissue. But this tissue is often mixed in with the trophoblastic tissue. It is important to know that no viable (able to live) fetus is being formed. Only a small percentage of patients with partial moles need further treatment after initial surgery. Partial moles rarely develop into malignant GTD.
What's the treatment for molar pregnancies?
- - most pass spontaneously
- suction curettage is safe, rapid, and effective if necessary
- induction of labor with oxytocin or prostaglandins not recommended
What can late pregnancy bleeding indicate?
- - placenta previa
- abruptio placentae
- a condition that may occur during pregnancy when the placenta implants in the lower part of the uterus and is close to or covering the cervical opening to the vagina (birth canal).
How is placenta previa classified?
- Based on the degree internal cervical os is covered by plancenta: complete or partial.
How is placenta previa diagnosed?
- by transabdominal ultrasound examination, accurate 97% of the time.
