Which of the following statements concerning fetal movements is true?
Fetuses spend most of their time in behavioral states 2F and 3F after 36 weeks.
The average number of fetal movements increases weekly until 40 weeks' gestation.
General body movements become organized between 20 and 30 weeks' gestation
Beyond 6 weeks' gestation, fetal movements are never absent for periods exceeding 13 minutes.
Which of the following is true regarding fetal movements?
The lowest number of weekly fetal movements occurs at term.
The number of weekly fetal movements peaks at 32 weeks' gestation.
In a normal pregnancy there should be 10 counts in a 12-hour period.
Declining amnionic fluid volume and space account for decreased fetal movements at 30 weeks' gestation.
Which of the following statements are true concerning contraction stress tests?
Identifies uteroplacental insufficiency.
Average time to completion is 75 minutes.
Equivocal-suspicious tests should be repeated in 24 hours
Variable decelerations are normal and do not require assessment.
Which of the following statements are true concerning nonstress tests?
They assess fetal condition rather than uteroplacental function.
It has a similar ability to predict fetal wellbeing as a contraction stress test.
The time to perform a nonstress test is much shorter than a contraction stress test.
All of the above
Which of the following statements regarding a nonstress rest is not true?
They do nor predict acute asphyxial events.
Vibroacoustic stimulation of the fetus is not allowed.
More than 20 minutes may be needed to account for fetal sleep cycles.
One acceleration is just as reliable as two in predicting healthy fetal status.
The components of a biophysical profile include all except which of the following?
Fetal tone
Fetal breathing
Contraction stress test
Arnnionic fluid volume measurement
Which of the following statements is true regarding the modified biophysical profile?
It is associated with a false-positive rate of 1.5%.
It is associated with a false-negative rate of 0.8 per 1000.
The American College of Obstetricians and Gynecologists agrees that it is as good as any other fetal test of well-being.
All of the above
According to the American College of Obstetricians and Gynecologists, which of the following statements concerning amnionic fluid volume is true?
Best measurement to detect oligohydramnios is the deepest vertical pocket.
Decreased amnionic fluid volume usually represents decreased uteroplacental perfusion.
Use of the deepest vertical pocket to define oligohydramnios leads to fewer unnecessary interventions.
All of the above
When is umbilical artery velocimetry considered abnormal?
End-systolic flow is absent
Systolic-diastolic ratio is less than 2
Systolic-diastolic ratio is greater than 4
Systolic-diastolic ratio >95th percentile for given gestational age
Middle cerebral artery Doppler is useful in which of the following scenarios?
Fetal intrauterine growth restriction
Routine assessment of fetal well-being
Pregnancies complicated by alloimmunization
All of the above
Which of the following are true concerning Doppler of the ductus venosus?
Absent or reversed flow is a sign of multiorgan damage.
It can be used to prevent iatrogenic preterm delivery.
Correlates well with umbilical artery Doppler to predict fetal well-being.
It is a useful surveillance tool for fetuses with
intrauterine growth restriction.
High resistance flow in the uterine artery between 22 and 24 weeks' gestation is correlated with which of the following?
Stillbirth
Abruption
Preeclampsia
All of the above
A benefit from vibroacoustic stimulation is which of the following?
It increases the predictability of the nonstress test.
It makes a nonstress test feasible in the preterm infant.
It shortens the time necessary to perform a nonstress test.
None of the above
A 33-year-old with chronic hypertension at 36 weeks' gestation reports decreased fetal movement at her prenatal care appointment. Ultrasound shows a deepest vertical pocket of 4 cm. What is the next best step?
Nonstress test
Umbilical artery Doppler
Assessment of fetal growth
Prolonged monitoring on labor and delivery
A 34-year-old at 35 weeks' gestation with gestational diabetes treated with insulin undergoes a biophysical profile (BPP). A score of 6/8 is obtained due to lack of fetal tone. What is your next best step?
Perform a nonstress test.
Send her to labor and delivery for delivery.
Send her to labor and delivery for a contraction stress test.
No further testing
A 30-year-old multigravida at 22 weeks' gestation has an anti-Kell titer of 1:64. What technique are you going to use to monitor this pregnancy?
Weekly nonstress test
Weekly biophysical profiles
Weekly middle cerebral artery Doppler
Nothing until she reports decreased fetal movement
Which of the following can affect fetal breathing?
Cervical exam
Amniocentesis
Maternal position
Fetal presentation
Fetal heart rate variability is influenced by all except which of the following?
Fetal sleep cycle
Maternal position
Maternal medication
Maternal cigarette smoking
