NCC EFM EXAM QUESTIONS ANDANSWERS
h Acceleration - -Onset to peak <30 seconds
- >15 bpm above baseline by >15 seconds but <2 minutes
-(Before 32 weeks gestation: peak >10 bpm and lasting >10 seconds)
Prolonged Acceleration - >2 minutes but <10 minutes
Early Deceleration - -Gradual decrease and return of FHR associated with a contraction
-Onset to nadir of >30 seconds
-Nadir occurs at the same time as the peak of the contraction
Late Deceleration - -Gradual decrease and return of FHR associated with a contraction
-Onset to nadir of >30 seconds
-Nadir occurs after the peak of the contraction
Prolonged Decleration - -Abrupt decrease with onset to nadir <30 seconds
-The decrease is >15 bpm by >15 seconds but <2 minutes
Recurrent Decelerations - Decelerations occurring with >50% of contractions in any 20 minutes
Intermittent Decelerations - Decelerations occurring with <50% of contractions in any 20 minutes
Sinusoidal Pattern - Visually apparent, smooth, sine wave-like pattern in FHR with cycle frequency of 3-
5/minute that persists for >20 minutes
Tachysystole - More than 5 ctx in a 10 minute segment averaged over a 30 minute period
Narcotic FHR Affects (2) - -Decrease in variability
-Decrease in frequency of acceleration
Stadol FHR Affects (2) - -Transient sinusoidal FHR pattern
-Slight increase in baseline rate
Cocaine FHR Affects (1) - -Decrease in variability
Corticosteroid FHR Affects (1) - -Decrease in variability with betamethasone but not dexamethasone
Magnesium Sulfate FHR Affects (2) - -Decrease in variability
, -Inhibition of increase accelerations as gestational age advances
Terbutaline FHR Affects (1) - Increase in baseline rate
Prematurity Affects on FHR (3) - -Higher baseline rate than term fetus
-Less variability than term fetus
-Less frequency and amplitude of accelerations than term fetus
Maternal fever Affects on FHR (2) - -Increase in baseline rate
-Minimal variability
Maternal Hyperthyroidism Affects on FHR (1) - Tachycardia
Maternal Hypothermia Affects on FHR (1) - Bradycardia
What is the primary purpose for the use of EFM? - Determine if the fetus is well oxygenated
Category I FHR Tracing - -Baseline rate between 110 and 160 bpm
-Baseline variability moderate
-No late or variable decelerations
-Early decelerations present or absent
-Accelerations present or absent
Category II FHR Tracing - -Bradycardia baseline rate not accompanied by absent variability
-Tachycardia baseline rate
-Minimal variability
-Absent variability without recurrent decelerations
-Marked variability
-Absence of induced accelerations after fetal stimulation
-Recurrent variable decelerations with minimal or moderate variability
-Prolonged deceleration
-Recurrent late decelerations with moderate variability
-Variable decelerations with "slow return to baseline"
Category III FHR Tracing - -Absent variability AND: recurrent late decelerations, recurrent variable
decelerations, or bradycardia
-Sinusoidal pattern
