Flashcards in glines antenatal testing Deck (22):
1

2 reasons for antenatal surveillance

ID patients at risk for fetal mortality/morbidity and decrease the rates of these

2

What is being measured in a non-stress test?

fetal heart rates (accelerations and variability)

3

Define a reactive test for a non-stress test

2 accelerations of 15 bpm ABOVE BASELINE lasting 15 sec each in a 20 minute period

4

What is a nonreactive non stress test?

something is missing so you didn?t get 2 acclerations in 20 min or one or both wasn?t 15 bpm above baseline, etc.

5

NST's are often done after this week

32 weeks gestation

6

What is a CST?

contraction stress test

7

What are 2 ways to perform a contraction stress test?

oxytocin or nipple stimulation (with warm towel) to induce contractions

8

What defines a VALID (not pos or neg) test contraction stress test?

the woman must have 3 contractions lasting 40-60 seconds within 10 minute period

9

Define negative and positive results of a CST

negative = no late decelerations with woman having adequate contractions; positive = late decelerations with > 50% of contractions

10

What defines a suspcious CST?

decelerations are present with some of the contractions but not > 50%

11

What defines an unsatisfactory CST?

inadequate uterine activity, i.e. not valid, oxytocin and nipple stim couldn?t induce contractions

12

What result from an NST and CST is a GOOD result? i.e. good news for mom/baby

NST a positive result is good, CST a negative result is good

13

What is the other way of antenatal testing aside from NST and CST?

Biophysical profile (BPP); it utilizes an NST and REAL TIME ULTRASOUND

14

What are the POSSIBLE scoring outcomes of a BPP?

0, 2, 4, 6, 8, 10 (10 =max) no such thing as 3, 5, 7 or 9

15

What are the 5 components of BPP?

fetal breathing movements, gross body movement, fetal tone, NST, and amniotic fluid volume

16

Which component of the BPP is "the first to show and the last to go"?

fetal breathing movements

17

for each of the 5 aspects of a BPP what are the 2 possible scores

either a 0 or a 2, why the person who came up with this decided to be a psycho and not make it 0 or 1 is beyond comprehension

18

When should you do antenatal testing on a diabetic mother

at 28-40 weeks

19

When should you do antenatal testing on a pre-ecclamptic woman

after 26 weeks

20

When should you do antenatal testing on a woman past her due date?

at 41-42 weeks

21

When should you do antenatal testing on a woman whose baby is diagnosied with IUGR?

at the time of diagnosis

22

When should you do antenatal testing on a woman with a history of a stillbirth?

at 32 weeks
