1

Lifespan of ovum and sperm

ovum = 24 hours
sperm = 72 hours

2

progesterone

a thermogenic hormone that raises the temperature, an objective sign that ovulation has occurred

3

psychosocial changes of pregnancy
1st trimester
2nd trimester

ambivalence is normal in 1st but not in second.

4

when does menstruation occur

14 days after ovulation

5

verifying pregnancy
1.what hormone
2.how long until this hormone is elevated
3.what meds can cause a false-positive/false-negative

1.human chorionic gonadotropin (hCG)
2.6-11 days in serum and 26 days in urine
3.Anticonvulsants, diuretics, tranquilizers

6

what is Nageles rule

used to estimate date of birth. Subtract 3 months and add 7 days to first day of last menstrual period

7

Non-stress test
1.what is it
2.normal finding
3.abnormal
4.positioning the client
5.intervention if no accelerations

1.noninvasive way of monitoring response of FHR to fetal movement
2.a normal finding is 2 or more accelerations (increase in FHR of atleast 15 that lasts 15 seconds) within a 20 minute period
3.does not do above. Indication of Contraction stress test (CST) or biophysical profile (BPP)
4.semi fowlers or left lateral
5.give a snack

8

Contraction stress test
1.methods
2.indications
3.normal finding
4.abnormal finding

1.nipple stimulation or oxytocin IV
2.non reactive NST
3.negative = 3 contractions over 10 mins with no decelerations
4.a positive CST = late decelerations occur with 50% of contractions is suggestive of uteroplacental insufficiency

9

Biophysical profile
1.what is it
2.normal vs abnormal

1.uses ultrasound to visualize physiological characteristics of fetus. A score of 0 or 2 is given for each category
2. (a)breathing: 1 episode of 30 seconds in 30 mins
(b)gross body movements-atleast 3 body or limb extensions with return to flexion in 30 mins
(c)fetal tone: atleast 1 episode of extension with return to flexion
(d)reactive NST
(e)amniotic fluid volume:atleast 1 pocket of fluid greater then or equal to 2 cm or more then 5 cm total

10

Amniocentesis
1.what can it do
2.when is it done
3.why would it be done in late pregnancy

1.detects presence of AChe in neural tube defects and can identify genetic diseases (trisomy 21, 18, 13)
2.performed at 14-16 weeks
3.assess fetal lung maturity LLS ratio of 2:1 indicates fetal lung maturity

11

Rho(d) immune globulin (Rhogam).

give to Rh-negative mothers. Must be an RN b/c its a blood product

12

Percutaneous umbilical blood sampling (PUBS)
1.what does it do

directly access fetal circulation and can be used for fetal blood sampling -> transfusion

13

Chorionic villi sampling
1.what is it
2.whats it for
3.when is it done

1.obtaining a sample of chorionic villi tissue (placental)
2.assess for fetal genetic abnormalities
3.first trimester

14

Maternal serum alpha fetoprotein screen (MSAFP)
1.what is it for
2.when should it be performed
3.what do low levels indicate
4.what do high levels indicate

1.screening tool for neural tube defects (NTD)
2.16-18 weeks
3.down syndrome
4.neural tube defect

15

normal fetal assessments
HR
normal kick count

FHR =110-160
10 kicks/2 hr (most active after meals and in the evening)

16

Oxytocin
1.whats it do
2.what should you monitor
3.when should you stop and what should you do

1.stimulates uterine contractions
2.monitor vitals, contractions, FHR
3.stop for late decelerations or tachysystole and have a tocolytic such as terbutaline

17

Methylergonovine Maleate
1.whats it for
2.what should you monitor
3.what should you do

1.For postpartum hemorrhage it stimulates uterine contractions
2.uterine tone and bleeding
3.massage fundus if uterine tone is shit

18

Terbutaline
1.uses
2.monitor
3.adverse effects
4.when should you hold
5.antidote

1.tocolytic
2.contractions, FHR, vitals
3.(a)tremors, dizziness, headache, tachycardia, hypotension, anxiety
4.chest pain, low BP 90, pulse greater 130, or signs of pulmonary edema or FHR greater then 180
5.bblocker

19

Indomethacin
1.use
2.monitor
3.considerations

1.tocolytic
2.contractions, FHR, vitals
3.(a)give with food to prevent adverse GI
(b)can mask maternal fever
(c)only give before less then 32 weeks of gestation

20

signs of hyperstimulation

1.more then 1 contraction every 2 mins or 5 in 10 mins
2.contractions longer then 90 secs
3.intensity greater then 90 mmHG
4.no relaxation of uterus between contractions

21

what do you do for hyperstimulation

give terbutaline

22

eye prophylaxis for newborns

1.make sure erythromycin/tetracycline is given within 1 hr
2.vitamin K IM within 1 hr
3.Hepatitis vaccine within 12 hours

23

Bulb syringe consideration

M before N

24

pathologic vs physiologic jaundice

pathologic jaundice occurs before 24 hours or is persistant for more than 7 days. It indicates increased RBC production or breakdown. This is usually caused by ABO or Rh incompatibility or infection

25

Human Papillomavirus
1.app

also known as genital warts

26

common site for IM injection for kids

vastus lateralis

27

should parents share rooms with new born babies

yes it is recommonded for the first few weeks in order to learn the newborns cues. However parents should avoid playing the newborn in their bed as it increases the risk for SIDS

28

what should you cover a baby with during sleep

a sleep sack or a one piece sleeper. Avoid blankets or quilt as they increase risk for SIDS

29

how should you check the temperature of water

elbow is the most sensitive. 120 F or lower to prevent burns

couvade syndrome

when the father gets pregancy like manifestations such as nausea, weight gain etc
