Uterine contractions are quantified as Correct Answer: the number of contractions present in a
10 min window
Normal frequency of uterine contractions Correct Answer: ≤5 contractions in 10 min, averaged
over a 30 min window
Tachysystole is Correct Answer: >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 Correct Answer:
"hyperstimulation" and "hypercontractility"
FHR patterns are defined by the characteristics of Correct Answer: baseline, 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 Correct
Answer: A. 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) Correct Answer: A. 2
B. 10
C. Indeterminate
Bradycardia Correct Answer: a baseline FHR <110
Tachycardia Correct Answer: a baseline FHR >160
Baseline FHR variability is determined in a (A) min window excluding (B) and (C) Correct
Answer: A. 10
B. accelerations
C. decelerations
Bareline FHR variability is defined as (A) in the baseline FHR that are (B) in (C) and (D)
Correct Answer: A. fluctuations
B. irregular
C. amplitude
D. frequency
Fluctuations are quantitated as the (A) of the (B) in bpm Correct Answer: A. amplitude
