Test Review 2025 | 100% CORRECT EXAM QUESTIONS + VERIFIED SOLUTIONS |
MULTIPLE CHOICE | GRADED A+!
assessment of of fetal well-being in 1st trimester - -confirm pregnancy
-confirm viability
-determine gestational age
-detect fetal anomalies
is transvaginal or transabdominal ultrasonography bettwe - transvaginal has better and clearer
images
transvaginal ultrasound - -detects gestational sac at 4-5 weeks
-fetal heart activity at 6-7 weeks
-BPD measurement and crown length at 14 weeks predicts EDB within 7-10 days
transabdominal ultrasound - -fetal heart beat at 10-12 weeks
-fetal weight during pregnancy
screening and diagnostic tests for first trimester - -ultrasound
-nuchal translucency
-maternal assays
-chorionic villus sampling
maternal assays - -coombs' test
-cell-free (DNA) screening
, nuchal translucency - measure nuchal folds (accumulation of fluids)
when to screen for nuchal translucency - between 10-14 weeks
positive nuchal translucency - >3mm
coombs' test - -Rh incompatibility
-detects other antibodies for incompatibility with maternal antigens
cell-free DNA screening - -fetal Rh status
-fetal gender
newest screening test for noninvasive prenatal genetic diagnosis - cell free DNA screening
chorionic villus sampling - -earlier diagnosis and rapid results
-removal of small tissue specimen from fetal portion of placenta (tissue reflects fetus genetic
makeup)
when to do chorionic villus sampling - between 10-13 weeks
where do chorionic villi originate - zygote
assessment of fetal well being in 2nd trimester - -establish or confirm dates
-confirm viability
-assess placental location
-assess for fetal anomalies
