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
Doing a CST is to see if the baby gets ____________. YOU DO NOT WANT THE BABY ____________ DURING THE TEST!
stressed
stressed
estimated growth and weeks gestation, predict outcome of pregnancies, FHR 110-160 BPM
Fetal well-being
Pregnancy in which the life or health of the mother OR fetus is jeapardized by a disorder contraindicated with or unique to the pregnancy.
High-Risk Pregnancy
Fetuses should be active unless ______
asleep
High risk mom- check fetal movement?
2-3 x day for 30 m -1 H
Low risk mom - check fetal movements?
1-2 x day for 30 M - 1 H
You should feel FM __ - ___ within each time frame < __ movements - do a NST,CST, and/or BPp.
5-6
3
No fetal movement in 12 H =
fetal alarm signal
Determine FM and well oxygenated fetus which is called?
Great fetal well-being
of kicks and time frame =
minimum of 10 movements in 12 H
Maternal assessment of fetal activity =
daily fetal movement count (kick count)
What ages are explained as high risk pregnancies?
less than 17 & greater than 34/35+
What age is considered to be advanced maternal age?
35+
Why would teens seek prenatal care late?
aren’t acceptable because of their fear that their family might not react to the situation positively
