Conditions during Pregnancy (part of pregnancy ppt) Flashcards
Exam 1
What would result in dizygotic or fraternal twins?
When two eggs are fertilized, the result is dizygotic or fraternal twins.
What would increase the risk of dizygotic twinning rates?
Risks for dizygotic twinning rates include:
the use of fertility drugs,
certain ethnicity,
or a family history of twinning.
What are monozygotic twins and how would they occur?
Monozygotic twins are identical and occur after the fertilization of one ovum.
What is monozygotic twinning considered?
Monozygotic twinning is considered a random, spontaneous event.
Mutli fetal risk increases maternal and fetal risk: Examples?
Risks include gestational diabetes, hypertensive disorders of pregnancy including preeclampsia, pulmonary embolism, fetal growth restriction, fetal anomalies, early pregnancy loss, stillbirth, and placenta previa.
Hyperemesis gravidarum (HG)
Hyperemesis gravidarum (HG) is characterized by unusually acute nausea and vomiting.
Hyperemesis gravidarum (HG) may lead to what?
HG may lead to weight loss, malnutrition, dehydration, ketonuria, and electrolyte imbalances.
What would nurses have to evaluate for with HG?
Nurses must evaluate for signs of dehydration, malnutrition, and laboratory tests.
What is the treatment for Hyperemesis gravidarum (HG)
Treatment may include antiemetics (although some have known teratogenic effects), intravenous (IV) rehydration, and the administration of parenteral electrolytes.
What are some risk factors for Hyperemesis gravidarum (HG)?
History of Hyperemesis gravidarum (HG)
Gestational trophoblastic disease
Multiple pregnancy
Hyperthyroidism (overactive thyroid)
GI disease prior to pregnancy
Depression and anxiety
Female fetus
Bleeding in EARLY Pregnancy (<20 weeks GA) can mean?
Abortion
Cervical Insufficiency
Ectopic Pregnancy
Gestational Trophoblastic Disease
Bleeding in LATE Pregnancy (>20 weeks GA) can mean?
Placenta Previa
Abruptio Placenta
What percent of women report vaginal bleeding in early pregnancy
Up to 20% of women report vaginal bleeding in early pregnancy.
Bleeding in Early Pregnancy (<20 weeks GA): Miscarriage/Abortion: For a subset of women, vaginal bleeding may be indicative of what?
For a subset of women, vaginal bleeding may indicate a miscarriage, ectopic pregnancy, or gestational trophoblastic disease.
What are other names for miscarriage? When does miscarriage occur?
A miscarriage, also known as a spontaneous abortion or spontaneous pregnancy loss, occurs before 20 weeks gestation.
When do the majority of miscarriages occur? Why?
Majority of miscarriages occur between weeks 5 and 8 - result of chromosomal abnormalities.
Bleeding in Early Pregnancy (<20 weeks GA): Miscarriage/Abortion:
If pregnancy loss is suspected, the woman should be evaluated for symptoms of:
What is used to evaluate?
bleeding,
cramping, and
the passage of tissue.
An ultrasound may be ordered to evaluate the pregnancy as well as beta hCG levels.
What percent of miscarriages are associated with chromosomal abnormalities?
Approximately 70% of miscarriages are associated with chromosomal abnormalities.
Bleeding in Pregnancy: Ectopic Pregnancy
A pregnancy that occurs outside the uterus, often occurs in the fallopian tube.
Bleeding in Pregnancy: Ectopic Pregnancy
What are they considered? What should be done?
Ectopic pregnancies are considered life-threatening for the mother and must not be continued.
Bleeding in Pregnancy: Ectopic Pregnancy
Signs of ectopic pregnancy include:
pelvic pain that may be unilateral and
bleeding.
How would treatment of ectopic pregnancy occur?
Treatment may be managed medically or surgically, depending on time of discovery.
Bleeding in Pregnancy: Gestational Trophoblastic Disease
Gestational trophoblastic disease (GDP), also known as a molar pregnancy, is a nonviable mass of trophoblastic tissue.
Bleeding in Pregnancy: Gestational Trophoblastic Disease
How is molar pregnancy?
A molar pregnancy grows at an abnormally high rate, produces abnormally high levels of beta hCG, and may spread beyond the uterus (gestational trophoblastic invasive mole or gestational choriocarcinoma).
Bleeding in Pregnancy: Gestational Trophoblastic Disease
How is it diagnosed?
Diagnosed on ultrasound.
Bleeding in Pregnancy: Gestational Trophoblastic Disease
How is it treated?
Treatment includes hysterectomy or dilation and curettage, possible prophylactic chemotherapy, serial serum hCG levels for 6 months to 1 year, and avoiding subsequent pregnancy for 1 year.
Hypertensive Disorders of Pregnancy: Gestational Hypertension
How is it diagnosed?
Gestational hypertension is diagnosed by systolic blood pressure greater than 140 mm Hg or higher and/or a diastolic blood pressure of 90 mm Hg or higher without protein in the urine or signs of end-organ dysfunction diagnosed at 20 weeks of pregnancy.
As many as half of the patients diagnosed with gestational hypertension go on to develop what?
As many as half of the patients diagnosed with gestational hypertension go on to develop preeclampsia.
Complications of gestational hypertension include?
Complications of gestational hypertension include preterm birth, small for gestational age (SGA) infants, and placental abruption.
Preeclampsia can occur in what percent of pregnancies?
Preeclampsia occurs in 3% to 5% of pregnancies.
Preeclampsia can cause what to the fetus specifically:
oligohydramnios
placental abruption
intrauterine growth restriction for the fetus
Preeclampsia can cause what to the mother specifically?
Can impact maternal organ systems causing renal damage, pulmonary edema, impaired liver function, cerebral edema, and thrombocytopenia.
How is preeclampsia diagonosed?
Diagnosis: when a patient has BP ≥ 140/90 mm Hg on two occasions at least 4 hours apart and has proteinuria.
Preeclampsia with Severe Features:
BP levels
Hypertension (>160/110 mmHg) with or without proteinuria and
Preeclampsia with Severe Features:
Platelet count?
Platelet count <100,000
Preeclampsia with Severe Features:
Serum creatinine liver
Serum creatine liver >1.1 mg/dL
Preeclampsia with Severe Features:
other features
Elevated liver enzymes, pulmonary edema, or
New-onset visual or cerebral symptoms.
