vasa previa
27
vasa previa diagnostics (2)
``` U/S using color doppler Apt test (after the fact) ```
28
vasa previa treatment
corticosteroids possible 3rd trimester hospitalization Cesarian delivery at 35 weeks
29
risks assoc. w/ PPROM before 26 weeks (2)
fetal pulm. hypoplasia | limb positioning defects
30
PROM diagnostics (2)p
Nitrazine paper | Fern test
31
when does the quickening occur
18-20 weeks | 16-18 weeks in multiple births
32
methods of dating the pregnancy (4)
uterus size quickening- when does it occur uterine fundus position at 20 weeks first trimester US- most accurate
33
protraction disorder (3)
cervical dilation rate at less than 1 cm/hr or less than 1.2-1.5 cm/hr (nulli/multi) latent phase longer than 20 or 14h (nulli/multiparous) second stage longer than 3h w/ anesthesia or 2h w/o anesthesia
34
arrest disorder (2)
no cervical dilation in the active phase of labor for > 2 h | no descent after 1 hour pushing
35
breech treatment
external cephalic version at 36 weeks w/ tocolytics to relax the uterus
36
most common cause of cephalopelvic disproportion
contraction of the mid-pelvis
37
diagnosis of funic cord prolapse
palpitation of pulsatile mass
38
diagnosis of occult prolapse
fetal HR changes
39
how to relieve shoulder dystocia
McRobert's manuever
40
early decelerations indicate
head compression
41
variable decelerations indicate
cord compression
42
late decelerations indicate
uteroplacental insufficiency
43
sign of fetal intolerance to labor
decelerations in fetal HR
44
risk factors that incr. risk of uterine rupture in VBAC (4)
vertical incision in uterus > 2 prior cesarian deliveries induction of labor (don't use ptocin) previous uterine rupture
45
definition of postpartum hemorrhage (2)
> 500 mL blood loss, vaginal birth | > 1000 mL blood loss, cesarian
46
most common cause of postpartum hemorrhage
uterine atony
47
how to diagnose postpartum hemorrhage (3)
10% decr. in HCT need for transfusion S&S of blood loss
48
diagnosing ovulatory function (2)
serum progesterone: > 3 ng/mL is evidence of recent ovulation. Measure 1 week prior to menses (day 21) ultrasound: follows dominant follicle, most accurate
49
ovarian reserve diagnostics (2)
Anti-mullerian hormone: how many eggs are left. measured any time. less than 1 ng/mL indicates poor embryo quality, poor response to ovarian stimulation FSH: measure on day 3 of cycle. greater than 20 indicates poor response
50
hysteroscopy use (2)
evaluate uterine cavity diagnostic & therapeutic- can remove polyp
51
semen analysis values (3)
volume: below 1.5 mL is low concentration: should be above 15 million motility: at least 40% should be motile
52
low volume of sperm sample w/ few sperm indicates (2)
androgen deficiency | GU obstruction/absence of vas deferens
53
vaginal bleeding with a closed cervix
Threatened abortion
54
incomplete abortion is signified by?
persistent bleeding & cramping following passage
55
vaginal bleeding with an open cervix before 20 weeks
inevitable abortion
56
recurrent SAB is?
> 3 consecutive pregnancy losses
57
mifepristone use? (3)
not given after 9 weeks PO, then buccal admin. 24-48h later follow up US in 7 days
58
absent fetal heart tones, no cardiac activity on US, retained pregnancy
