partial previa
Type of placenta previa where the more central portion of the placenta covers the opening
complete or central previa
Low implantation of the ____ in the uterine cavity causes placenta previa
blastocyst
Is vaginal delivery allowed when there is placenta previa present?
no
T or F. Immediate C-section is warranted when there is a massive hemorrhage in placenta previa
T
Contractions leading to cervical change before 37 weeks of pregnancy
premature labor
What IM injections are given to mother in premature labor to reduce complications?
betamethasone
What IM injections reduce incidence of premature birth by 30%?
progesterone
Spontaneous break in the amniotic sac before onset of regular uterine contractions
premature rupture of membranes (PROM)
When the infant is full term, the period between membrane rupture and the onset of labor is ____
brief
When infant is pre-term, the period between membrane rupture and onset of labor is ____, which increases risk of fetal death
prolonged
A cause for PROM is increased intrauterine tension due to ____ or ____
hydramnios or multiple pregnancies
PROM in pre-term pregnancy (28 to 34 weeks) is treated with hospitalization and ____ if there is evidence of infection
induction of labor
PROM in term pregnancy when vaginal delivery isn’t achieved within 24 hours following prom, induction of labor with ____ is usually done
oxytocin
Pregnancy that persists for 41 weeks or more
prolonged post-term pregnancy
T or F. Prolonged pregnancies are not induced because dates may be wrong, inducing comes at a higher risk, hard on mom and baby
T
What are the 3 phases of the first stage of labor?
- early labor (0-4cm)2. active labor (4-8cm)3. hard labor or transition (8-10cm)
Which stage of labor is the longest?
first
Stage of labor that begins at full cervic dilation (10cm) and baby’s head has begun to press into the birth canal
second stage of labor
Stage two ends with the ____
birth of the baby
Stage of labor where the uterus rests for 15 minutes, placenta detaches from the uterine wall, and is delivered by expulsion by the birth canal
third stage of labor
The third stage is managed by administering ____ and ____ which when given at time of birth, can reduce severe bleeding
oxytocin and ergonovine
Lie
position of baby in relation to mom
Lie: fetus is lying lengthwise (vertically) in the uterus
longitudinal fetal lie
Lie: fetus is lying crosswise or horizontally in the uterus
transverse fetal lie
T or F. Caesarean is always performed when fetus is at a transverse lie
T
Lie: maternal axes cross at a 45 degree angle, forming an unstable lie that’ll always become either longitudinal or transverse during the course of labor
oblique fetal lie
direction of baby in relation to mom’s pelvis
position
part of baby that passes through the pelvis first
presentation
Presentation: back part of skull (occiput) is the point of direction
vertex presentation
Presentation: chin is the point of direction
face presentation
Presentation: brow is the point of direction
brow presentation
Presentation: sacrum is the point of direction and the feet are crossed and the thighs are flexed on the abdomen
complete breech presentation
__% of breech babies are delivered by cesarean section
