Intermediate Fetal Monitoring
QUESTIONS & VALID ANSWERS
-approximate mean FHR rounded to increments of 5bp during a 10 min segment
- duration must be at least 2 min. or the baseline for that period is indeterminate - correct
answer ✔✔Baseline Rate
baseline rate less than 110 bpm - correct answer ✔✔Bradycardia
baseline of greater than 160 bpm - correct answer ✔✔Tachycardia
fluctuations in baseline FHR that are irregular in amplitude and frequency - correct answer
✔✔Baseline variability
amplitude range undetectable - correct answer ✔✔Absent variability
amplitude range > undetectable but <5/min - correct answer ✔✔Minimal variability
amplitude ranges 6-25 bpm - correct answer ✔✔Moderate variability
amplitude range greater than 25 bpm - correct answer ✔✔Marked variability
visually apparent abrupt (<30 sec to peak) increase in FHR above baseline for less than 2
minutes
-15bpmx15sec for 32 weeks and up
, -10bpmx10sec for less than 32 weeks - correct answer ✔✔Acceleration
acceleration lasting longer than 2 minutes but less than 10 minutes. - correct answer
✔✔Prolonged Acceleration
A visually apparent usually symmetrical gradual (more than 30 sec) decrease in FHR and return
to baseline associated with a contraction
-nadir occurs at the same time as the peak of the contraction - correct answer ✔✔Early
Deceleration
visually apparent, usually symmetrical gradual decrease in FHR and return to baseline associate
with a contraction
-delayed in timing with the nadir occurring after the peak of the contraction - correct answer
✔✔Late Deceleration
visually apparent abrupt decrease in FHR
-decrease is 15 bpm lasting for more than 15 sec but less than 2 minutes - correct answer
✔✔Variable Deceleration
visually apparent decrease in FHR that is at least 15 bpm lasting greater than or equal to 2
minutes but less than 10 minutes from onset to return to baseline - correct answer
✔✔Prolonged Deceleration
a deceleration that lasts greater than or equal to 10 minutes - correct answer ✔✔Baseline
change
occurring the greater than or equal to 50% of contractions in a 20 minute period - correct
answer ✔✔Recurrent
