Questions with 100% Verified Answers Latest Update
Question: First prenatal visit screening routine
Answer:
Beta-hCG, ultrasound, H/H, blood type/Rh, rubella/varicella/Hep B titers, STI screening, urine
culture, aneuploidy screening.
Question: Clinical confirmation of pregnancy
Answer:
Lab urine/serum beta-hCG, fetal heart activity, or ultrasound visualization.
Question: Most sensitive pregnancy test in early pregnancy
Answer:
Serum beta-hCG.
Question: Qualitative vs. quantitative beta-hCG
Answer:
Qualitative gives positive/negative result; quantitative gives numerical level.
Question: Normal beta-hCG rise in early pregnancy
Answer:
Rises rapidly, doubling approximately every 48-72 hours.
Question: Implication of abnormal beta-hCG rise in early pregnancy
Answer:
Ectopic pregnancy or nonviable pregnancy.
Question: Best test for gestational dating with irregular cycles
Answer:
Ultrasound, especially before 20 weeks.
Question: Diagnostic test when uterine size does not match menstrual dates
Answer:
Ultrasound to assess gestational age and pregnancy dating.
,Question: Timing of most accurate ultrasound dating
Answer:
Before 20 weeks gestation.
Question: Ultrasound screening for chromosomal abnormalities at 12 weeks
Answer:
Fetal nuchal translucency ultrasound.
Question: Timing of fetal nuchal translucency screening
Answer:
Between 11 and 14 weeks gestation.
Question: What fetal nuchal translucency evaluates
Answer:
Fluid collection at posterior fetal neck to screen for aneuploidy risk.
Question: Conditions screened by nuchal translucency
Answer:
Trisomy 21, Trisomy 18, Trisomy 13, and Turner syndrome.
Question: Noninvasive screening for aneuploidies at 10 weeks
Answer:
Cell-free DNA screening.
Question: Timing of cell-free DNA screening
Answer:
At 10 weeks gestation or later.
Question: What cell-free DNA testing measures
Answer:
Fragments of fetal DNA circulating in maternal plasma.
Question: Classification of cell-free DNA testing
Answer:
Screening test.
Question: Next step after abnormal cell-free DNA screening
, Answer:
Invasive diagnostic testing (CVS or amniocentesis).
Question: Karyotyping
Answer:
Analysis of fetal chromosomes to detect chromosomal abnormalities.
Question: Do nuchal translucency and cell-free DNA diagnose Down syndrome?
Answer:
No; they are screening tests requiring diagnostic confirmation with CVS or amniocentesis.
Question: Ultrasound performed at 18-22 weeks
Answer:
Fetal anatomy survey/detailed anatomy scan.
Question: Best timing for fetal anatomy scan
Answer:
18-22 weeks gestation.
Question: Purpose of fetal anatomy scan
Answer:
Screen for congenital malformations (cardiac, neural tube, abdominal wall, renal, skeletal).
Question: Low H/H at first prenatal visit assessment
Answer:
Anemia in pregnancy.
Question: Additional lab for suspected pregnancy anemia
Answer:
Ferritin.
Question: Risk for Rh-negative pregnant patient
Answer:
Rh isoimmunization if the fetus is Rh positive.
Question: Routine timing for Rh immune globulin
