- What is the normal baseline fetal heart rate range?
- 110 to 160 bpm.
- Over what minimum time segment is a baseline FHR determined?
- A minimum of 10 minutes.
- Fetal tachycardia is a baseline FHR above what value, sustained for at least 10 minutes?
- 160 bpm.
- Fetal bradycardia is a baseline FHR below what value, sustained for at least 10 minutes?
- 110 bpm.
- Moderate FHR variability is defined as an amplitude range of ____ beats per minute.
- 6 to 25
- What does moderate FHR variability reliably indicate about fetal status?
- Absence of fetal metabolic acidemia at that time.
- What causes early decelerations?
- Fetal head compression during contractions.
- What is the underlying cause of late decelerations?
- Uteroplacental insufficiency.
- What most commonly causes variable decelerations?
- Umbilical cord compression.
- When does the nadir of a late deceleration occur relative to the contraction peak?
- After the peak of the contraction.
- What onset speed defines a variable deceleration's shape?
- An abrupt drop, onset to nadir in less than 30 seconds.
- What defines a Category I FHR tracing?
- Baseline 110 to 160, moderate variability, no late or variable decelerations, with or without early decelerations or accelerations.
- What defines a Category III FHR tracing?
- Absent variability with recurrent late or variable decelerations or bradycardia, or a sinusoidal pattern.
- How is a Category II FHR tracing best described?
- Indeterminate; any tracing that is not Category I or Category III.
- What FHR pattern shows a smooth, sine-wave-like undulating baseline?
- A sinusoidal pattern.
