Test 5 Flashcards
life or well-being of the mother or infant is jeopardized by a biophysical or psychosocial disorder coincidental w/ or unique to pregnancy
high risk pregnancy
the goal is to determine whether the intrauterine environment continues to support the fetus
Electronic fetal monitoring
Types of electronic fetal monitoring (3)
Nonstress test
Vibroacoustic stimulation (VAS)
Contraction Stress Test (CST)
prenatal test used to check on a baby’s health; baby’s heart rate is monitored to see how it responds to the baby’s movement
Non-Stress Test
How Nonstress test is performed (3)
-Woman is seated in a recliner in semi-fowlers
-FHR is recorded w/ a Doppler transducer
-Tocodynamometer is applied to detect uterine contractions or fetal movements
what is considered a “reactive” NST (2)
Gestation > 32 weeks: 2 accelerations lasting 15 sec each within a 20 min window
Gestation <32 weeks: 2 accelerations lasting 10 sec each within a 20 min window
NST results and meaning
reactive: normal/good
nonreactive: requires further evaluation
Nonreactive NST:
if there’s no activity for 40 min or more, get provider
common for NST to take up to ______ to determine results
20 minutes
Reasons to do NST based on term: (2)
1st-2nd tri: after diagnosis of fetal anomalies
3rd: determine whether the intrauterine environment continues to support the fetus
Patients that are recommended for NST: (6)
Chromosomal abnormalities
Intrauterine growth restriction
Poorly controlled maternal DM
Hemorrhage/Risk of hemorrhage
Fetal congenital abnormalities
Maternal Heart disorders
Buzzer placed on stomach –> see if baby reacts on monitor to buzzer
Vibroacoustic stimulation (VAS)
Procedure done one of two ways:
-Nipple-stimulated ___________
-Oxytocin-Stimulated ___________
contraction stress test (CST)
Contraction Stress Test interpretations: (2)
Negative: desired
Positive: Late FHR decelerations are present
Obtains amniotic fluid to test for potential complications
amniocentesis
who would be offered an amniocentesis (4)
Older mom
Genetic concerns
Fetal maturity
Fetal hemolytic disease
Why are amniocentesis done? (3)
- Prenatal diagnosis of genetic disorders/ congenital anomalies (neural tube defects)
- Assessment of pulmonary maturity
- Diagnosis of fetal hemolytic disease (rare)
used to monitor fetus in pregnancies complicated by conditions that may affect oxygenation
Daily fetal movement count (DFMC)
AKA: Fetal Kick Counts
Why do parents do DFMC (FKC)
Used to monitor the fetus in pregnancies complicated by conditions that may affect fetal oxygenation
How do parents do DFMC (FKC)
-Count of fewer than 3 kicks in 1 hour warrants further evaluation by a nonstress test
-Tell patient 3 kicks/1hr is an AVERAGE
(Baby can kick more during certain times of day so important to use average)
considered to be the most valuable diagnostic tool used in obstetrics
ultrasounography
two routes of ultrasounds
abdominal
transvaginal
three levels of ultrasound
Standard (basic)
Limited
Specialized (targeted
why are ultrasounds done
Fetal heart activity
Gestational age
Fetal growth
Fetal anatomy
