Assessing High Risk Pregnancy Flashcards
Fetal monitoring for 20-30 minutes
Vibroacoustic stimulation - sound and vibration used to elicit fetal response
Non-stress test (NST)
NST: reactive =
have a normal FHR baseline with fetal movement (accelerations = FM)
NST: non-reactive =
additional testing needed
What are the AWHONN guidelines for NST?
2 15x15 accelerations in 20 mins in a 32-40 week gestation
1 10x10 acceleration in 1 hour for 24-31.6 weeks gestation
Monitoring the baby on the monitoring stick for 20-30 mins and make sure its reactive!
FHR = 120-140 BPM, need acceleration, shows us o2, FM, and fetal well being = REACTIVE
NST: FHR must be between _______ - _____ BPM within 30 mins and must have ______ accelerations!
110-160
2
What does the NST look at?
looks at 4 pockets! greater than 5 cm or 1 pocket greater than 2 cm of fluid in it!
A substance (fetal antigen) that is present in a pregnant woman’s blood; test for AFP are used to determine pregnancy. AFP in amniotic fluid can be diagnostic of inborn error of metabolism or fetal structure abnormalities, neutral tube defects.
Alpha-Fetoprotein
When do RoGam injections need to be preformed?
when the baby is Rh positive and the mother is Rh negative.
When does the mom need to get the RoGam injections when having a Rh Positive fetus?
RoGam shot @ 28 weeks
Mom receives RoGam shot 72 H after birth to prevent moms antibodies from attacking fetus in the next pregnancy!
FHR baseline for 10-20 M
Contraction started
Findings are negative, positive, and equivocal
Contraction Stress Test (CST) or Oxytocin Contraction Test (OCT)
In a CST what is done during the test?
Get baseline and get mom to contract
Nipple stimulation
IV Pitocin/Oxytocin
3 contractions in 10 M
How fetus reacts to contractions
no late decelerations in a CST =
negative
Late decelerations in a CST =
positive
You want a negative CST because it means?
the baby is not stressing bc of the contractions
The HR is going to decrease during a CST=
positive CST
