Fetal and Neonate assessment Flashcards
The mean duration of a singleton pregnancy (birth of only one child during a single delivery with a gestation of 20 weeks or more) is __________
280 days/40 weeks
Term is defined as the period from __________________ (optimal time for delivery)
37 weeks to 42 weeks
Early term ______weeks
37 to 38
Full term ______weeks
39 to 40
Late term ______weeks
41 to 42
Determinations of gestational age is most accurate when ultrasonographic measurement of the fetus or embryo is performed in the ___________________.
first trimester (up to and including 14 weeks)
Recommended for all pregnancies given its ability to :
- Viability
- Fetal number
- Placental location
- Screen for fetal structural abnormalities in the second trimester
An increased risk for delivering a small-for-gestational age baby and/or having a preterm delivery is associated with _____________________________.
low maternal gestational weight gain.
Higher risk for delivering a large-for-gestational age baby and/or cesarean delivery is associated with ____________.
excessive gestational weight gain.
Although the _________ examination has several limitations (especially in the setting of a small fetus, maternal obesity, multiple pregnancy, uterine fibroids, or polyhydramnios), it is safe, is well tolerated, and may add valuable information to assist in antepartum management.
abdominal
what is Leopold Maneuver designed to do?
identify specific fetal landmarks or to reveal a specific relationship between the fetus and the mother
1st maneuver - measurement of fundal (uterus) height, uterus can be palpated above the pelvic brim at approximately 12 weeks’ gestation then should increase 1 cm per week, reaching the umbilicus at ________.
20-22 weeks
Fundal height between 20 and 32 weeks gestation (in cm) is __________ ______ to the gestational age ( in weeks) in a healthy women of average weight with an appropriately growing fetus.
approximately equal
Maximal fundal height occurs at approximately ___ weeks’ gestation, after which time the fetus drops into the pelvis in preparation for labor

Fetal Growth Restriction is associated with a number of significant adverse perinatal outcomes: (5)
- Intrauterine Demise
- Neonatal Morbidity
- Neonatal Mortality
- Cognitive Delay in
Childhood - Chronic Diseases (Obesity, Type II Diabetes, CAD, Stroke in Adulthood
Maternal disorders associated with fetal growth restriction include any condition that can potentially result in vascular disease, such as :
pregestational diabetes, hypertension, antiphospholipid antibody syndrome, autoimmune diseases and renal insufficiency, malnutrition, and substance abuse
Fetal conditions that may result in growth restriction include:
teratogen exposure, including certain medications; intrauterine infection; aneuploidy, most often trisomy 13 and trisomy 18; and some structural malformations, such as abdominal wall defects and congenital heart disease.
Fetal growth restriction is associated with an increased risk for ______
stillbirth
The risk for stillbirth is further increased when fetal growth restriction occurs in the context of ________ or _______.
oligohydramnios or abnormal diastolic blood flow in the umbilical artery.
