About the Lecture
The lecture Labor Stage 1: Fetal Heart Rate Tracing by Veronica Gillispie, MD, FACOG is from the course Intrapartum Care. It contains the following chapters:
- Fetal Heart Rate Tracing
- Fetal Heart Rate Tracing – Categories
Included Quiz Questions
What is the range for a normal baseline fetal heart tracing?
- 110-160 beats per minute
- 100-150 beats per minute
- 130-160 beats per minute
- 100-130 beats per minute
- 135-145 beats per minute
How would you describe an acceleration in the fetal heart tracing in a fetus with a gestational age greater than 32 weeks?
- An increase in fetal heart rate by 15 beats per minute for 15 seconds over a 2 minute tracing
- An increase in fetal heart rate by 10 beats per minute for 15 seconds over a 2 minute tracing
- An increase in fetal heart rate by 15 beats per minute for 10 seconds over a 2 minute tracing
- An increase in fetal heart rate by 10 beats per minute for 10 seconds over a 20 minute tracing
- An increase in fetal heart rate by 20 beats per minute for 15 seconds over a 20 minute tracing
A 27 year old G1P0 at 42 weeks gestational age is admitted for induction of labor. She is on pitocin and her last cervical exam was unchanged from the one prior; 5cm/ 80% effaced/ -2 station with a category 1 fetal heart tracing and experiencing contractions every 5-6 minutes. Pitocin infusion was increased to help the progression of labor and 20 minutes later, she is having 1 contraction every minute and fetal heart tracing has a baseline of 165 with absent variability and two late deceleration over a 20 minute strip. What category is the fetal heart tracing and what is the next best step in management?
- Category 3, patient has tachysystole and the pitocin must be stopped
- Category 2, patient has tachysystole and the pitocin should be stopped
- Category 1, it is ok to continue the course of management as is
- Category 2, the patient is likely not taking in deep breaths due to pain from regular contractions and should get oxygen supplementation
- Category 2, the patient should be rotated to relieve cord compression
Which of the following fetal heart tracings is a Category 2 tracing?
- Baseline 135 with moderate variability and variable decelerations and one late deceleration over a 20 minute strip
- Baseline 145 with moderate variability and no decelerations over a 20 minute strip
- Baseline 165 with absent variability and variable decelerations, no late decelerations or accelerations over a 20 minute strip
- Baseline 160 with moderate variability and accelerations over a 20 minute strip
- Baseline 125 with moderate variability a few early decelerations over a 20 minute strip
Which of the following is true of a category 3 strip?
- It indicates uteroplacental insufficiency
- It indicates indeterminate acid/base status of the fetus
- It indicates cord compression
- It indicates head compression of the fetus
- It is always a sign of fetal anemia
A 29-year-old G4P3 woman at 40 weeks gestational age was admitted to the labor ward in spontaneous active labor. Her last cervical exam was 7 cm dilation/90% effacement/-2 station with a bulging bag of water (intact membranes) and fetal heart tracing was unremarkable with a baseline heart rate of 140 beats per minute and moderate variability without any decelerations. 30 minutes later she felt a large gush of fluid with her contraction and the fetal heart tracing started displaying regular early decelerations with each contraction. How can this phenomenon be best described?
- Physiologic response to fetal head compression after rapid descent of the fetal head in the pelvis
- Cord compression due to prolapse of the cord
- Uteroplacental insufficiency due to maternal intravascular volume depletion
- Fetal anemia resulting in a sinusoidal fetal heart tracing pattern
- Fetal bradycardia due to uteroplacental insufficiency
All of the following is true of a sinusoidal pattern on a fetal heart tracing, except...
- ...it represents cord compression
- ...it indicates fetal anemia
- ...it is a category 3 strip
- ...it requires immediate intervention
- ...it suggests abnormal fetal acid/base status
Which of the following statements is true of tachysystole?
- It is defined as greater than 5 contractions over 10 minutes
- It can only be determined by an internal uterine pressure catheter
- It can be monitored without intervention as long as the fetal heart tracing is not Category 3
- It is defined as over 10 contractions in 10 minutes
- It is defined as overlapping contractions without any uterine relaxation in between contractions
