Obstetrics Gabbe Chapter 15: Intrapartum Fetal Evaluation

Front 1

Thegoal of intrapartum FHR monitoring is to assess the ___________________ during labor so that timely and appropriate steps can betaken when necessary to avoid fetal hypoxic injury.

Back 1

adequacy of fetal oxygenation

Front 2

Oxygen is transported by maternal and fetal blood alongthe oxygen pathway, which includes the maternal lungs, heart,vasculature, uterus, placenta, and ________________.

Back 2

umbilical cord

Front 3

Theconsequences of interruption of fetal oxygenation can leadsequentially to:

Back 3

1. fetal hypoxemia,

2. fetal hypoxia,

3. metabolic acidosis,

4. metabolic acidemia, and eventually

5. injury or

6. death.

Front 4

Theobservation of an FHR deceleration that reaches its nadir in lessthan 30 seconds (variable deceleration) suggests:

Back 4

compression of the umbilical cord

Front 5

Alate deceleration, by definition, reaches its nadir in:

Back 5

30 seconds or more

Front 6

Historically,late decelerations have been attributed to ____________, which suggests interruption of the oxygen pathway atthe level of the uterus or placenta

Back 6

uteroplacental insufficiency

Front 7

Aprolonged deceleration can result from interruption of the oxygenpathway at:___________.

Back 7

any point.

Front 8

ModerateFHR variability or accelerations reliably exclude _________________ at the time they are observed.

Back 8

fetal hypoxic injury
