GRADED 100% VERIFIED)
Baseline Rate - correct ans-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
Bradycardia - correct ansbaseline rate less than 110 bpm
Tachycardia - correct ansbaseline of greater than 160 bpm
Baseline variability - correct ansfluctuations in baseline FHR that are irregular in amplitude and
frequency
Absent variability - correct ansamplitude range undetectable
Minimal variability - correct ansamplitude range > undetectable but <5/min
Moderate variability - correct ansamplitude ranges 6-25 bpm
Marked variability - correct ansamplitude range greater than 25 bpm
Acceleration - correct ansvisually 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
, Prolonged Acceleration - correct ansacceleration lasting longer than 2 minutes but less than 10
minutes.
Early Deceleration - correct ansA 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
Late Deceleration - correct ansvisually 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
Variable Deceleration - correct ansvisually apparent abrupt decrease in FHR
-decrease is 15 bpm lasting for more than 15 sec but less than 2 minutes
Prolonged Deceleration - correct ansvisually 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
Baseline change - correct ansa deceleration that lasts greater than or equal to 10 minutes
Recurrent - correct ansoccurring the greater than or equal to 50% of contractions in a 20 minute
period
Intermittent - correct ansoccurring with less than 50% of contractions in a 20 minute period
Sinusoidal - correct ansvisually apparent undulating sine wave like pattern in FHR and cycle frequency
of 3-5 per minute which persists for greater than or equal to 20 minutes
Category 1 - correct ans-baseline 110-160
-moderate variability
