Name 14 prenatal screening tests and what they're for.
|
blood type, Rh status, antibody screen - ID's fetuses at risk of isoimmune dx
H&H - baseline lab, r/o anemia Rubella antibody screen - ID's women susceptible to acquiring rubella during pregnancy TB - ID's infected women Heb B surface antigen - ID's women whose babies could be trx at birth to prevent Hep B Serologic test for VDRL (syphilis) - trx reduces infant mortality HIV - ID women for tx and pernatal tx to decrease transmission to fetus Urinalysis - screen for DM, PIH, and renal dx RBC, WBC, Bacteria - R/o UTI DM (24- 28 wks)screening - R/o gest DM Pap smear - ID cervicitis and precancerous and cancerous lesions Neisseria gonorrhea and chlamydia cx - ID treateable STD to prevent fetal mortality Triple screen - AFP/HCG/estriol - 16 -20 wks ID neural tube, down syndrome |
|
|
Gestational age can be estimated by determining LMP; What is Nagele's rule?
|
EDC=first day of LMP-3mos+7days+1yr.
|
|
|
most widely used screening method to assess for fetal well being
|
NST - can be started as early as 30 to 32 weeks, reactive = 2 fetal HR accel, NONreactive = no FHR accel after 40 min
reactive is good |
|
|
What is a CST?
|
Contraction stress test: evaluates the reserve function of the placenta. Most often used after a nonreactive NST. Evaluates 3 spontaneous contractions in a 10 min period. Looks for FHR decels at the onset of contraction. Late decels are a positive CST and delivery should be considered.
|
|
|
What is biophysical profile?
|
uses US to eval 5 parameters, each recieving 0 - 2 pts. 10 pts is max
|
|
|
What is amniotic fluid index?
|
decreased volume (oligo) - uteroplacental insufficiency, fenitourinary or lung anomalies.
increased volume (polyo) - chromosomal disorders, mat DM, anatomic anomalies such as TEF |
|
|
What lab tests are done for assessing fetal lung maturity?
|
L/S ratio: ratio equat to or great than 2.o indicates fetal lung maturity
PG : minor surfactant also present in amniotic fluid after 35 wks Fetal lung maturity assay: measures surfactant/albumin ratio in amniotic fluid Lamellar body counts: storage form of surfactant |
|
|
List the 5 major maternal infection potentials.
|
1. TORCH - Toxoplasmosis, others, rubella, cytomegalovirus infx, and herpes simplex (all cross the placenta)
2. STD's 3. Other communicable dx: flu, mumps, parvo, Hep B, varicella 4.Chorioamnionitis 5. group B Strep |
|
|
Fetal well-being is generally influenced by: A. Placental function and medications B. Maternal resources C. Lifestyle choices, placental function, and maternal resources |
C. Placental function determines fetal growth while fetal well-being is influenced by function, maternal resources, and lifestyle choices. |
|
|
Effects of increased estrogen during the pregnancy has sytemic maternal effects including all EXCEPT: A. Kidneys enlarge B. Lung compliance increases C. Increased blood plasma |
B. Estrogen affects the respiratory system by increasing mucus, not increasing compliance. |
|
|
The total recommended weight gain during a pregnancy of a woman with normal body mass index (BMI) is: A. 25-35 pounds B. 30-40 pounds C. 15 - 25 pounds |
A. Total weight gain for normal BMI women is 25 - 35 pounds with a recommended increase of 300 calories per day over the regular dietary recommedation of 2200 calories. |
