|
biophysical risk factors |
factors that originate within the mother or fetus and affect the development or functioning of either one or both examples: genetic disorders, nutritional and general health status, medical related illness, poorly controlled DM, hypertensive disorder |
|
|
psychosocial risk factors |
maternal behaviors and adverese lifestyles examples: distrubed interpersonal relationships emotional distress inadequate social support unsafe cultural practices substance abuse |
|
|
sociodemographic risk factors |
where she lives and resources examples are lack of parental care, low income, marriage, ethnicity, age, |
|
|
environmental risk factors |
hazards in home or work infection drugs pollutants |
|
|
what group doesn't go to get prenatal care because its not covered |
undocumented |
|
|
being labeled a high risk pregnancy may result in |
increased vulnerability stress ambivalence inability to accomplish the tasks of parenthood fear |
|
|
daily fetal movement count tests |
once a day for 60 min 2-3 times a day for 2 hours on until 10 movements are felt 10 movements in 12 hours |
|
|
when are you concerned with movement |
less the 3 movements in 1 hour |
|
|
how can an UX be done |
abdominally or vaginally abdomin is used after 1st trimester want full bladder vaginal is beter for 1st trimester |
|
|
if were doing gestational testing we first need a |
UX to see how old |
|
|
when do you do the anatomical scan to confirm due date |
18-20 wks |
|
|
indications for UX use |
FHR age growth anatomy genetic disorders placental poisiton adjunct to other invasive tests |
|
|
when can fetal hr be determined by UX |
6 wks |
|
|
measurement that are most useful for gestational age calculation |
crown rump length (after 10 wks) biparetal diameter (after 12 wks) head circumference and abdominal circumference femur circumfrance |
|
|
head circumference and abdominal circumfance should correspond with |
gestational wks |
|
|
plaques on heart mean |
downsyndrome |
|
|
Nuchal translucency |
NT uses UX measurement of fluid in the nape of the neck between 10-14 wks to identify fetal abnormalities |
|
|
what is abnormal for NT |
more then 3 mm |
|
|
elevated NT and low maternal serum maker levels means |
increased risk for chromosomal abnormalities |
|
|
high NT alone means |
cardiac problems |
|
|
UX findings that indicate possible Down syndrome |
short or no nasal bone short femur echogenic bowel emlarged renal pelvis soft markers not diagnostic |
|
|
do most cases of placenta pre via in the second trimester resolve on their own |
yes |
|
|
can we use UX for grading of placental age |
yes |
|
|
Dopler flow analysis |
can tell S/D from fetus placenta and arteries |
|
|
oliginohydramios |
low fluid less then 2cm associated with anomalies, growth resrticitons, abnormal Hr during labor |
|
|
hydraminos |
excess fluid more then 8cm associated with neural tube defects, obstruction of GI tract |
|
|
normal AFI amniotic fluid index |
10 cm-25 cm its made of all four quadrants |
|
|
Biophysical profile |
non invasive assessment of fetus based on acute and chronic markers of fetal disease its like a physical exam including VS |
|
|
when is BPP used |
late second or third trimester |
|
|
whats a normal BPP |
8-10 |
|
|
modifies BPP |
done to shorten the time the test takes looks at NST and amniotic fluid |
|
|
doppler study |
dont do this unless getting blood sample from pubs or unless the baby has one artery or vein |
|
|
when is amniocentesis possible |
after 14 wks |
|
|
indications for amniocentesis |
diagnosis genetic disorders assessment of pulmonary maturity diagnosing fetal hemolytic disease |
|
|
genetic concerns that may lead to amniocentesis |
over 35 history of chromosomal abnormalities |
|
|
late in pregnancy assessment of fetal lungs can be done by examining for the presence of |
PG |
|
|
fetal hemolytic disease |
when moms Rh neg and babies rh pos and give mom rogam |
|
|
amniocentesis maternal complications |
hemmoraghe fetomaternal hemmoragge infection labor abruptio placentae damage to intestines or bladder amniotic fluid embolism |
|
|
amniocenstesis fetal complicaitons |
death hemmorage infection injury from needle risks may be minimized by using UX during procedure |
|
|
first and second trimester assessment is directed primarily at the |
diagnosis of fetal anomalies |
|
|
methods used for antepartum fetal evaluation in high risk patients |
NST MBPP |
|
|
when do you do antepartum fetal evaluations |
32-34 wks |
|
|
goal of the 3rd trimester antepartum assessment |
to determine if the intrauterine environment is supportive to the fetus |
|
|
NST |
watch heart rate in response to movement, contraction or stimulation |
|
|
most common reason for absence in FHR acceleration is |
babys sleeping |
|
|
procedure for NST |
sit in chair movements need to be recorded can drink orange juice or do sound stimulation |
|
|
NST interpretation |
reactive or non reactive want it to be reactive |
|
|
fetal HR tells us the reactions between |
Sym and parasym |
|
|
how many accelerations do you need in 20 min |
two if don't get 2 do another 20 min if still not send for long term monitoring if it isn't seen after 40 min then a BPP will be done |
|
|
what do you wan to see on the NST |
a fetal HR that increases 15 beats lasting for 15 seconds |
|
|
Contraction stress test is used to identify |
jeaporized fetus that is stable as rest but showed compromise after stress |
|
|
CST vs NST |
CST shows earlier warning signs and it has less false positives but more expensive |
|
|
whats a contraindication for a CST |
if the women cannot deliver vaginally at the time of the test |
|
|
two methods for the CST |
nipple stimulaiton oxytocin stimulation |
|
|
if no late decelerations are seen its a _____CST |
negative want to be negative |

yes |
