Flashcards in OB goes on Deck (49):
1

The normal and predictable sequence of sexual maturation proceeds with

breast budding-->
adrenarche (hair growth)-->
a growth spurt-->
then menarche.

2

menarche is usually at age

~12

3

body weight of __________- pounds is needed before menses begins

85 to 106

4

There are two weird critical elements for secondary sexual characteristics:

sleep and optic exposure to sunlight.

5

______________-- is characterized by premature menses before breast and pubic hair development.

McCune Albright Syndrome

6

______________ occur in 25-35% of females with Mullerian agenesis.

Renal anomalies

7

Lady who cant pee after labor w/ ab pain

epidural--> bladder not working--> urine dribble

Bladder atony- over full

Temporary and reversible

8

When do you give rhogam

28- 32 weeks in Rh- mom
After delivery if baby is Rh +

9

When cant you dilate and evacuate a baby

over 24 weeks

do a vaginal delivery instead

10

Compare complete vs incomplete abortion

complete: whole baby out
incomplete: bleeding, open os, some fetal parts remain

11

What do you call pulling a baby out by his feet

internal podalic version
Breech baby

12

Placenta location where you have to do a c-section

less than 2 cm from os

13

___________` is the most common abnormal karyotype encountered in spontaneous abortuses,

Autosomal trisomy

accounting for approximately 40-50% of cases.

14

The risk of developing microcephaly and severe intellectual disability is greatest between ?

eight and 15 weeks gestation.

never seen with doses even exceeding 50 rad at less than eight weeks or greater than 25 weeks gestation.

15

. The FVL mutation is associated with obstetric complications including ?

stillbirth, preeclampsia, placental abruption and IUGR

16

Ultrasound criteria for a missed abortion are

a CRL of > 7 mm with no cardiac activity

17

benign ovarian tumor with ascites and pleural effusion that resolves after resection of the tumor.

meigs syndrome

18

________________- is the most common risk factor for protraction and/or arrest disorders in the first stage of labor.

Hypocontractile uterine activity

19

Hypocontractile uterine activity is the most common risk factor for protraction and/or arrest disorders in the ______________

first stage of labor.

20

Arrest of labor is diagnosed at cervical dilation ≥6 cm in a patient with ruptured membranes and

No cervical change for ≥4 hours despite adequate contractions

No cervical change for ≥6 hours with inadequate contractions

21

Arrest of the second stage of labor was defined as no progress (descent or rotation) for:

●Nulliparous women with an epidural: ≥4 hours
●Nulliparous women without an epidural: ≥3 hours
●Multiparous women with an epidural: ≥3 hours
●Multiparous women without an epidural: ≥2 hours

22

Time from onset of labor to complete cervical dilation.

First stage normal labor

23

Time from complete cervical dilation to fetal delivery

second stage of labor

- can also be viewed in terms of fetal rather than maternal changes, ie, changes in fetal station and descent.

24

Time between fetal delivery and placental delivery.

third stage of labor

25

For management of slow labor progression over 2 hours, in the active phase (cervix ≥6 cm), we administer

oxytocin

increase the frequency and strength of this patient’s contractions. If the patient does not have cervical change once she is having more frequent contractions on oxytocin, it would be reasonable to place an IUPC (intrauterine pressure catheter) to assess the strength of the contractions.

26

_____________ is typically used for cervical ripening and labor induction

Misoprostol

27

women with cervical dilation <6 cm are considered to be

in latent phase

cervical dilation above 6 cm = the active phase

28

We manage second stage arrest with ?

an operative delivery

29

Avoid operative delivery in the second stage as long as?

the fetus continues to descend and/or rotate to a more favorable position for vaginal delivery and the fetal heart rate pattern is not concerning.

30

cytotec is

misoprostol

31

______________ are all associated with breech presentation.

Prematurity
multiple gestation
genetic disorders
polyhydramnios
hydrocephaly
anencephaly
placenta previa
uterine anomalies
uterine fibroids

32

A prolonged latent phase is defined as

>20 hours for nulliparas and >14 hours for multiparas, and may be treated with rest or augmentation of labor

not yet reached the active phase (more than 4-6? cm)

33

What size baby is likely to have shoulder dystocia

4500 g

34

Optimal position for delivery

OA
(back of baby's head against front of moms body)

35

can you push the baby head back in

yes- its called zavenoli procedure

36

________________ are all associated with an increased incidence of shoulder dystocia.

Fetal macrosomia
maternal obesity
diabetes mellitus
postterm pregnancy
hx of shoulder dystocia
prolonged second stage of labor

37

In secondary arrest of dilation, no further cervical change in the active phase for over four hours. _________ is often recommended in this situation.

Amniotomy

38

How does a vesicovaginal fistula present?

painless loss of urine into the vagina often after pelvic surgery

39

What is one situation where you cannot use OCPs

In migraine

40

Aside from OCPs, what can treat PMS

SSRI- daily or only in luteal phase

41

What symptoms are present in bladder cancer

hematuria
↑ ua frequency
urge incontinence

42

When can you give prenatal steroids

23-34 weeks

43

obstetric complication in which fetal blood vessels cross or run near the os

Vasa praevia- umbilical cord inserts into the membranes.
rare

44

Fresh frozen plasma contains :

fibrinogen, clotting factors V and VIII.

45

Cryoprecipitate contains

fibrinogen, factor VIII and von Willebrand’s factor.

46

Common presenting signs of an abruption include

abdominal pain, bleeding, uterine hypertonus and fetal distress.

47

Common Risk factors of an abruption include

Risk factors include smoking, cocaine use, chronic hypertension, trauma, prolonged premature rupture of membranes, and history of prior abruption.

48

Smoking increases the risk of several serious complications of pregnancy, including

placental abruption, placenta previa, fetal growth restriction, preeclampsia and infection.

49
