NCC EFM EXAM QUESTIONS AND VERIFIED ANSWERS
What do you always look at first on a strip?
Baseline
When can you not determine a baseline?
less than 2 min
What does variability look at?
oxygenation, acidity
how is variability measured?
amplitude range from baseline
what does fetal sleep cycle look like?
normal baseline, minimal variability, no access, reacts to stimuli
what do we think if we see accelerations with pushing?
partial occlusion of umbi vein and compensation
what do we do with accelerations with pushing?
reposition, push with every other or every third, d/c pit
Tachysystole
greater than 5 contractions in 10 min period averaged over 30 minutes.
Sinusoidal indicates
anemia, blood loss
sinusodial pattern
smooth and wave like 3-5 min greater than or equal to 20 minutes
Extrinsic factors effecting EFM
placenta
maternal circulation
fetal-placental circulation
placental transfer
uterine blood flow
cord
fluid
Intrinsic factors effecting EFM
