Which ultrasound approach is the most accurate for establishing or confirming gestational age?
- A
A third-trimester ultrasound measuring fetal size
- B
A first-trimester ultrasound using crown–rump length
- C
A single fundal-height measurement
- D
A second-trimester ultrasound measuring fetal size
The second trimester begins at weeks, and the third trimester begins at weeks.
At about how many gestational weeks can cell-free DNA screening be offered? Enter the number of weeks.
Select all assessments commonly included during prenatal visits. Choose every correct answer.
- A
Review of maternal history and symptoms
- B
Blood pressure measurement
- C
Routine Doppler study at every visit
- D
Weight or weight-gain pattern
- E
Fetal heart tones and, as pregnancy advances, fundal height and reported movement
True or false: Fetal growth is assessed over time rather than determined from a single measurement.
- A
True
- B
False
A patient receives a positive cell-free DNA screening result. Which response is most appropriate?
- A
Treat the result as confirmation of a fetal condition
- B
Repeat the same screening method as an independent screen without counseling
- C
Discuss counseling, ultrasound assessment, and the option of diagnostic testing
- D
Conclude that diagnostic testing is unnecessary
The estimated due date is conventionally days after the LMP. Naegele’s rule adds days and subtracts months from the LMP.
Which changes are common physiologic adaptations during pregnancy? Select all correct answers.
- A
Plasma volume rises more than red-cell mass, which can lower measured hemoglobin through dilution
- B
Blood pressure typically rises markedly throughout pregnancy
- C
Kidney filtration increases
- D
Urinary frequency is common
- E
Placental hormones increase insulin resistance
What examination is recommended for all pregnancies, ideally at 18–22 weeks, regardless of the aneuploidy screening method?
A fundal-height pattern differs from what is expected for gestational age. What is an appropriate next assessment to consider?
- A
Use the single fundal-height measurement to determine fetal health conclusively
- B
Consider ultrasound assessment of fetal size, fluid, anatomy, or placental and umbilical blood flow
- C
Change the established due date based only on the size discrepancy
- D
Begin nonstress testing for every pregnancy with a size discrepancy
For a pregnancy conceived through assisted reproductive technology, what information should guide pregnancy dating?
Which group best describes tests commonly included in early prenatal laboratory screening?
- A
Complete blood count, blood type and Rh status, urine testing and culture, and screening for relevant infections
- B
Fetal Doppler studies and biophysical profiles for every pregnancy
- C
Only a fetal anatomy ultrasound and fundal-height measurement
- D
Only cell-free DNA screening, with no maternal laboratory testing
A pregnant patient reports mild breathlessness with exertion. Which interpretation best reflects common respiratory adaptations while recognizing the need for clinical context?
- A
Pregnancy normally reduces ventilation and oxygen demand, so breathlessness cannot be a common adaptation
- B
Breathlessness always indicates a complication and requires no further contextual assessment
- C
Increased ventilation and oxygen demand can contribute to mild exertional breathlessness, but symptoms should be evaluated in context
- D
Respiratory changes are not expected until after birth
A pregnant patient has a lower measured hemoglobin than before pregnancy but no other concerning findings. Which normal physiologic change can help explain this?
- A
Red-cell mass rises more than plasma volume, concentrating hemoglobin.
- B
Plasma volume rises more than red-cell mass, diluting measured hemoglobin.
- C
Blood volume and red-cell mass remain unchanged.
- D
Hemoglobin falls because kidney filtration decreases.
A patient is unsure of the last menstrual period and has irregular cycles. Which approach provides the most accurate ultrasound estimate of gestational age?
- A
A third-trimester ultrasound measuring fetal size
- B
A second-trimester ultrasound measuring fetal size
- C
A first-trimester ultrasound using crown–rump length
- D
A fundal-height measurement at a single prenatal visit
A patient receives a positive cell-free DNA screening result for a common trisomy. What is the most appropriate interpretation and next step to discuss?
- A
Explain that the result is not a diagnosis and discuss counseling and the option of diagnostic testing.
- B
Tell the patient the condition is confirmed and treatment should begin.
- C
Repeat multiple independent screening methods until one is negative.
- D
Reassure the patient that a positive result has no clinical significance.
True or false: A positive prenatal screening result confirms that the fetus has the condition being screened for.
- A
True
- B
False
What clinical term describes a pregnancy with no ultrasound confirming or revising the estimated due date before 22 weeks?
Using the conventional pregnancy-dating estimate, how many days after the first day of the last menstrual period is the estimated due date?
