NCC-EFM Test
Uterine contractions are quantified as - ANS-the 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 - ANS-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 - ANS-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) - ANS-A. 2
B. 10
C. Indeterminate
Bradycardia - ANS-a baseline FHR <110
Tachycardia - ANS-a baseline FHR >160
Baseline FHR variability is determined in a (A) min window excluding (B) and (C) -
ANS-A. 10
B. accelerations
C. decelerations
