HIGH RISK CLIENTS Flashcards
(63 cards)
a concurrent disorder, pregnancy related complication or external factor jeopardizes the health of the mother, the fetus or both
high risk pregnancy
2 groups of high risk pregnancy
- women with preexisting illness
- women who develop complications of pregnancy
Factors that originate within the mother or fetus and affect the development or functioning of either or both.
biophysical risks
Comprised of maternal behaviors and adverse lifestyles that have a negative effect on the health of the mother or fetus (both).
psychosocial risks
Factors arising from the mother and her family and place the mother and fetus at risk. (Ex: lack of prenatal care, low income, marital status, age, residence, etc)
sociodemographic risks
Risks that include hazards of the workplace and the woman’s general environment. (pesticides, lead, mercury), radiation, infections and pollutants)
environmental risks
- Assessment of the FHR for whether a good baseline rate and a degree of variability are present
- Record FHR for 20 min
rhythm strip testing
rhythm strip testing categories:
- none apparent
- extremely small fluctuations
- amplitude range 6-25 bpm
- amplitude range > 25 bpm
absent
minimal
moderate
marked
- a test in pregnancy that measures fetal heart rate in response to movement and contractions.
- done for 10-20 mins
nonstress test
nonstress test result:
2 accelerations of FHR (by 15 beats or more) lasting for 15 seconds occur after movement within the chosen time period
reactive
nonstress test result:
- No accelerations occur with the fetal movements
- No fetal movements occur or if there is low short-term fetal heart rate variability (less than 6 bpm) throughout the testing period
non reactive
- Producing a sharp sound of approximately 80 decibels at a frequency of 80 Hz, startling and waking the fetus
- done in conjunction with a nonstress test
vibroacoustic stimulation
what is the expected response in a vibroacoustic test
acceleration of FHR
- External fetal heart monitor is applied and obtain baseline FHR
- May be done if NST results are nonreassuring
- Involves nipple stimulation until uterine contraction begin
contraction stress testing
contraction stress testing result:
No fetal heart rate decelerations are present with contractions
negative / normal
contraction stress testing result:
50% or more of contractions cause a late deceleration
positive / abnormal
true or false - during nonstress test Woman should not lie supine to prevent supine hypotension syndrome
true
after the contraction stress test, how many minutes should you observe the woman after to see that contractions are quiet and preterm labor does not begin?
30 minutes
Measures the response of sound waves against solid objects
ultrasonography
used to:
- Diagnose pregnancy
- Confirm the presence, size, and location of the placenta and amount of amniotic fluid
- Establish that a fetus is growing and has no gross anomalies
- Establish sex
- Establish the presentation and position
- Predict maturity – biparietal diameter
ultrasonography
In determining the fetus’s biparietal diameter, UTZ is used. By measuring the biparietal diameter (side-to-side measurement) of the fetal head, ___ is determined.
fetal maturity
In 80% of pregnancies in which the biparietal diameter of the fetal head is 8.5 cm or greater, it can be predicted that the infant will weigh more than ___ at fetal age of 40 weeks
2500g or 5.5 lbs
Two other measurements commonly made by ultrasound to predict maturity are ___ and ___
head circumference and femoral length
Measures the velocity @ which RBC in the uterine & fetal blood vessels travel
doppler umbilical velocimetry
