At less than 32 weeks, a reactive tracing is defined as 2 accelerations at least this many beats above baseline

These are the 5 components of the biophysical profile.

A contraction stress test is positive is you have late decelerations with this percentage of contractions?

Per ACOG and SMFM, this is the one indication for the use of umbilical artery doppler velocimetry as a part of antepartum fetal surveillance.

These are the components of a modified biophysical profile.

This component of a fetal heart rate tracing is an indication of fetal oxygenation status/ oxygenation reserve.

In order to get points for fetal breathing, a sonographer/sonologist must see one episode of fetal breathing for this long throughout the entirety of the biophysical profile.

This is the false positive rate of a non-reactive non-stress test as a test for fetal reassurance.

This vessel, connecting the umbilical vein to the portal portion of the inferior vena cava, should always have forward flow within it. If not, your baby's got a problem.

This test for antepartum fetal surveillance has the lowest false positive rate.

These types of decelerations may be observed in up to 50% of all non-stress tests.

This is the fetal stage of quiet sleep.

This is the type AND frequency of antenatal surveillance for someone greater than 40 weeks gestation.

In pregnancies impacted by fetal anemia, this value is measured in the middle cerebral artery.

If a tracing is non-reactive, this may be used before considering moving toward ordering a biophysical profile.

Type 1 diabetes, chronic hypertensives and those with lupus should begin twice weekly non-stress tests at this gestational age.

This is what should be done in a patient with a biophysical profile of 6/10 at 34 weeks gestation who presented for decreased fetal movement, non-reactive NST.

This is the phenomenon in which blood is shunted to to vital organs when growth restriction is becoming worse and worse.

This should be done if a patient presents to OB Triage at 37 weeks with a fetus in the 3rd percentile for estimated fetal weight with intermittent absent end diastolic flow.

This component of the biophysical profile, if abnormal, is an indication of chronic compromise to the utero-placental unit.

These occur due to perceived fetal hypoxemia at the level of arterial chemoreceptors, leading to alpha adrenergic activation and subsequent vagal compensation.

A biophysical profile score is 0/8 corresponds to a fetal death rate of this within 1 week.

In doing an amniocentesis for quantification of fetal lung maturity, the lamellar body count should be greater than this in order to be considered mature.

Notching of these vessels have been said to be seen possibly in those women who suffer from severe gestational hypertension/ pre-eclampsia.

This is the risk of twin-to-twin transfusion syndrome in mono-chorionic/ di-amniotic twin gestations?
