APGO OBGYN Obj Flashcards
late decelerations are a sign of
uteroplacental insufficiency
variable decelerations are a sign of
umbilical cord compression
early decelerations are a sign of
head compression by uterine contractions
physical findings of down syndrome
flattened nasal bridge small size small rotated cup-shaped ears sandal gap toes hypotonia protruding tongue short broad hands simian creases epicanthic folds oblique palpebral fissures
fetal size of type 1 diabetic mom
small
fetal size of gestational diabetic mom
large
signs of infant sepsis
fetal tachycardia
minimal variability in HR
appears:
pale
lethargic
high temp
infants born to diabetic mothers are at increased risk for developing:
hypoglycemia polycythemia hyperbilirubinemia hypocalcemia respiratory distress
contraindications to expectant management of severe preeclampsia remote from term (<32wks)
- thrombocytopenia <100,000
- inability to control BP with max doses of two anti-HTN meds
- non-reassuring fetal surveillance
- LFTs elevated >2x normal
- eclampsia
- persistent CNS sx
- oliguria
signs of Mg sulfate toxicity
diminished or absent deep tendon reflexes (areflexia) then... respiratory depression (12-15mg/dl) or cardiac depression (>15mg/dl)
benefits of fetal fibronectin test
good negative predictive value in symptomatic women (preterm labor)
MOA of Mg sulfate
competes with calcium for entry into cells
causes of elevated maternal serum AFP (alpha fetoprotein)
twin gestation, neural tube defects, pilonidal cysts, cystic hygroma, sacrococcygeal teratoma, fetal abdominal wall defects, fetal death
US markers suggestive of dizygotic twisn
- non-identical twins a dividing membrane thickness greater than 2mm twin peak (lambda) sign different fetal genders two separate placentas (ant and post)
causes of breech presentation
prematurity multiple gestation genetic disorders polyhydramnios hydrocephaly anencephaly placenta previa uterine anomalies uterine fibroids
