Uterine contractions are quantified as - ANSthe number of contractions present in a 10 min
window
Normal frequency of uterine contractions - ANS≤5 contractions in 10 min, averaged over a
30 min window
Tachysystole is - ANS>5 contractions in 10 min, averaged over a 30 min window. Should be
qualified as to the presence or absence of FHR decelerations
Terms describing uterine contractions that have been abandoned - ANS"hyperstimulation"
and "hypercontractility"
FHR patterns are defined by the characteristics of - ANSbaseline, variability, accelerations,
and decelerations
Baseline FHR is determined by approximating the mean FHR rounded to increments of (A)
bpm during a (B) min window, excluding (C) and (D) and periods of (E) FHR variability -
ANSA. 5
B. 10
C. accelerations
D. decelerations
E. marked
There must be at least (A) minutes of identifiable baseline segments in any (B) minute
window, or the baseline for that period is (C) - ANSA. 2
B. 10
C. Indeterminate
Bradycardia - ANSa baseline FHR <110
Tachycardia - ANSa baseline FHR >160
Baseline FHR variability is determined in a (A) min window excluding (B) and (C) - ANSA. 10
B. accelerations
C. decelerations
Bareline FHR variability is defined as (A) in the baseline FHR that are (B) in (C) and (D) -
ANSA. fluctuations
B. irregular
C. amplitude
D. frequency
Fluctuations are quantitated as the (A) of the (B) in bpm - ANSA. amplitude
