NU 400- Complications of Pregnancy UPDATED ACTUAL
Questions and CORRECT Answers
At what gestation is a fetus considered preterm? 20.0-36 6/7 weeks
What criteria are needed for a woman to be considered - Regular Contractions: 6 or more hours
in pre-term labor? - Cervical change of 2 cm or more
, Diagnosis of Preterm Labor: - Transvaginal Ultrasound: cervical length
- Fetal Fibronectin- swab done to look under microscope- glue in the amniotic
sac that is connected to the uterine lining
Causes of preterm labor - Hemorrhage
- Infection
- Problems with placenta
- Issues with prostaglandin
- Premature rupture of membranes
- Too much amniotic fluid
- Multiple gestation pregnancy
Preterm Labor Medications: - Rest
-Hydration
Tocolytic Medications:
-Terbutaline (Brethine)
-Magnesium Sulfate
-Indomethacin (Indocin)
- Nifedipine
Antenatal Corticosteroids:
- Betamethasone
Neuroprophylaxis
- Magnesium Sulfate
Maternal Risks of Premature Rupture of Membranes: Maternal infections: chrioamnionitis, endometritis
Abruptio placenta, retained placenta
Increased rate of C-section
Fetal/Newborn Risk of Premature Rupture of - Fetal or Neonatal Sepsis
Membranes - Preterm delivery with preterm complications
- Hypoxia (umbilical cord compression due to decreased fluid)
- Fetal deformities if rupture of membranes is less than 26 weeks
Cervical Insufficiency: Painless dilation of the cervix during the second trimester
When cervical insufficiency is diagnosed: - History of one or more second trimester pregnancy losses due to painless
cervical dilation
- Previous delivery less than 34 weeks and short cervical length less than 25
mm before 24 weeks
Monozygotic Twins: identical twins formed when one zygote splits into two separate masses of
cells, each of which develops into a separate embryo
Inflammation of the uterine lining: endometritis
-Fever, lower abdominal pain
Chorioamnionitis: Infection of the amniotic membranes
Dizygotic Twins: often called fraternal twins, occurring when two eggs each get fertilized by
two different sperm, resulting in two zygotes in the uterus at the same time
