Flashcards in antenatal care Deck (40):
1

when is the booking visit

12 weeks

2

what investigations at this point

FBC- anaemia, glucose; BMI; urine dips; ABO and Rh, syphilis and rubella, HIV test

3

purpose of the booking visit

give information, confirm pregnancy, date the pregnancy (LMP), identify maternal risk factors, offer screening for fetal disorders

4

what investigations at this point

FBC- anaemia, glucose; BMI; urine dips; ABO and Rh

5

disadvantages of LMP calculations

relies on 28 d cycle and ovulation at 14d

6

what should happen to an unvaccinated Rubella lady

do not vaccinate until after the pregnancy

7

what are underweight women more at risk of

IUGR

8

disadvantages of LMP calculations

relies on 28 d cycle and ovulation at 14d

9

what is an obese woman more at risk of

C sections, pre eclampsia

10

why is accurate dating important

downs screening relies on accurate age, pre and post term labour

11

what is measured at >13 weeks on US dating scan

crown rump length

12

risk factors gestational diabetes

obese, FHx diabetes, prev gestational diabetes

13

why is accurate dating important

downs screening relies on accurate age, pre and post term labour

14

when should a woman with risk factors for gestational diabetes have GTT

16 and 28 weeks

15

risk factors gestational diabetes

obese, FHx diabetes, prev gestational diabetes

16

at what weeks is a Rhesus negative woman given anti D

28 weeks, 34 weeks

17

what para is more at risk of pre eclampsia

primiparous woman- so needs 2 additional antenatal check ups in the last trimester

18

from how many weeks is the woman given 3 weekly antenatal check ups

25 weeks

19

at what weeks is a Rhesus negative woman given anti D

28 weeks,34

20

what weeks are trimester 3

28- term

21

what weeks are trimester 1

1-12

22

what weeks are trimester 2

13-27

23

what weeks are trimester 3

28- term

24

when would transvaginal US be used

early pregnancy, good views of the cervix. not >12 weeks

25

uses ultrasound

confirmation- miscarriage, ectopic; gestational age; fetal growth; multiple pregnancy; structural anomalies; placental localisation; amniotic fluid volumes; cervical length; CTG

26

what is looked for for multiple pregnancy chorionicity on US

v (lambda) sign, thickened membranes separating the two embryos

27

how long should a CTG be performed for and why

30 mins. as fetal deep sleep cyles

28

what is US used for in suspected oligo/polyhydramnios

calculate amniotic fluid index.

29

what are the normal accelerations on CTG

>15 bpm in for 15 secs

30

how long should a CTG be performed for and why

30 mins. as fetal deep sleep cyles

31

what is looked for on the CTG

accelerations, decelerations, baseline variability, FHR

32

what are the normal accelerations on CTG

?

33

what should the baseline variability be

>10bpm.- shows normally functioning autonomic nervous system

34

when is the dating scan in a normal pregnancy

12 weeks

35

what are tachycardias associated with

hypoxia, infection

36

what should the baseline variability by

>10bpm.- shows normally functioning autonomic nervous system

37

when is the dating scan in a normal pregnancy

12 weeks

38

in addition to the normal 2 scans what scans are needed for an at risk fetus

growth scans, amniotic fluid volumes, Doppler uterine artery scans. CTG used around labour

39

what is Doppler US uterine arteries measuring

systolic and diastolic flows in uterine artery shows placental resistance. infarction placenta leads to increased resistance and less perfusion to the fetus

40

what is Doppler US fetal vessels measuring

middle cerebral artery flow increases in IUGR and anaemia- redirection to the fetal head
