| Question | Answer |
|---|---|
| How often are prenatal visits scheduled in an uneventful pregnancy? | - q mo for 7 mo - then q 2 wk for mo 8 - them q wk for mo 9 |
| When should fundal height be assessed? | wk 18 |
| GBS test is done routinely at what week? | 35-37 wk |
| What are nursing management to abd ultrasound? | advise pt drink 1-2 quarts of fluid prior to fill bladder to lift and stabilize uterus, wedge under rt hip |
| What are nursing management to transvaginal untrasound? | assist into lithotomy position, lubricate probe with gel |
| What is nonstress test (NST)? | test for fetal well-being with transducer and tocotransducer. |
| What does nonreactive NST indicate? | fetal heartbeat does not accelerate adequately with fetal movement or no fetal movements occur in 40 min. Anticipate CST and/or BPP. |
| What is vibroacoustic stimulation? | sound source activated over maternal abd to awaken sleeping fetus |
| What is contraction stress test (CST)? | stimulate contractions and determine how fetus will tolerate stress of labor |
| What is a negative CST? | normal finding: within 10 min period, there are no late FHR declerations with 3 contractions |
| What are risks with CST? | hyperstimulation of uterus, preterm labor (monitor contractions that are >90 sec and/or 2 min in frequency) |
| What is biophysical profile (BPP)? | uses ultrasound to assess fetal well-being in five areas |
| What are the 5 areas in BPP assessment? | reactive FHR, fetal breathing movements, gross body movements, fetal tone, amniotic fluid volume (normal score:8-10) |
| What is amniocentesis? | test for chromosomal abnormalities, infection, and lung maturity performed after 14 wk |
| What are high and low levels of alpha-fetoprotein (AFP) associated with? | High: neural tube defects, anencephaly Low: down syndrome, mole pregnancy |
| What do fetal lung tests include? | 2:1 Lecithin/sphingomyelin (L/S) ratio = fetal lung maturity, phosphatidylglycerol (PG) absence linked with resp distress |
| What are nursing management for amniocentesis? | informed consent, empty bladder, locate placenta with ultrasound, cleanse abd with antiseptic, administer RhoGam if pt Rh-, have pt rest 30 min after procedure |
| What are risks of amniocentesis? | amniotic fluid emboli, hemorrhage, Rh isoimmunization, infection, inadvertent fetal damage, PROM |
| What is percutaneous umbilical blood sampling (PUBS)? | common method for fetal blood sampling and transfusion. (Can also detect chromosomal anomalies) |
| What is chorionic villus sampling (CVS)? | Can test for chromosomal anomalies earlier than amniocentesis, done at 10-12 wk |
| What are nursing management for CVS? | same as amniocentesis except fill bladder b/4 procedure and assist in lithotomy position for transvaginal probe |
