NCC-EFM Test 2023 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

• 10
• accelerations
• decelerations
• 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

• 10
• 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

• accelerations
• decelerations

Bareline FHR variability is defined as (A) in the baseline FHR that are (B) in (C) and (D)

• Correct Answer A. fluctuations
• irregular
• amplitude
• frequency

Fluctuations are quantitated as the (A) of the (B) in bpm - Correct Answer A. amplitude

• peak-to-trough

Absent FHR Variability - Correct Answer undetectable Minimal FHR Variability - Correct Answer >undetectable and ≤ 5 bpm Moderate FHR Variability - Correct Answer 6-25 bpm Marked FHR Variability - Correct Answer ≥25 bpm Accelerations are defined as visually apparent - Correct Answer abrupt increases in the FHR Abrupt increase is - Correct Answer an increase from the onset of the acceleration to the peak in <30 seconds To be called an acceleration, the peak must be (A) an the acceleration must last (B) from the onset to the return to baseline FHR - Correct Answer A. ≥ 15 bpm
