EFM Test UPDATED ACTUAL Exam
Questions and CORRECT ANSWERS
Baseline Rate - CORRECT ANSWER- ✔✔Approx mean FHR rounded to increments of 5
bpm during a 10 min segment. Minimum baseline duration must be 2 min, excluding periods
of marked variability or segments of baseline that differ by >25 bpm.
Bradycardia - CORRECT ANSWER- ✔✔Less than 110 bpm
Tachycardia - CORRECT ANSWER- ✔✔Greater than 160 bpm
Acceleration - CORRECT ANSWER- ✔✔Visually abrupt increase above baseline (onset to
peak <30sec) that is 15 by 15, or 10 by 10 before 32 weeks
Early deceleration - CORRECT ANSWER- ✔✔Gradual decrease in FHR (>30 sec) with the
nadir occuring at the same time as the peak. In most cases, onset and recovery occur
simultaneously with the contraction.
Late deceleration - CORRECT ANSWER- ✔✔Gradual decrease in baseline associated with
uterine contraction. Nadir occurs after the peak of the contraction. Onset, peak, and recovery
occur after onset, peak, and ending of uterine contraction.
Variable deceleration - CORRECT ANSWER- ✔✔Visually abrupt decrease in FHR, (onset to
beginning of nadir is <30sec) Decrease is >15bpm, lasting >15sec, and less than 2 min.
Prolonged deceleration - CORRECT ANSWER- ✔✔Decrease greater than or equal to 15
bpm, lasting greater than or equal to 2 min, and less than 10 min from onset to return to
baseline.
Recurrent deceleration - CORRECT ANSWER- ✔✔Occurring with greater than or equal to
50% of contractions during any 20 min segment.
acidemia - CORRECT ANSWER- ✔✔Increase H+ in blood
, acidosis - CORRECT ANSWER- ✔✔Increase H+ in tissue
Hyperstimulation - CORRECT ANSWER- ✔✔Persistent pattern of more than 5 contractions
in 10 min, contractions lasting 2 min or longer, or contractions of normal duration occuring
withing 1 min of each other
FSE reflects _____ wave - CORRECT ANSWER- ✔✔R wave. FSE detects the PQRST
complex, then filters everything out but R wave
Contraindications to FSE application - CORRECT ANSWER- ✔✔HIV, chronic hepatitis,
HSV or other untreated STDs, mother who is a known hemophilia carrier when sex of fetus is
unknown
Parasympathetic nervous system influences the heart via the ______ nerve - CORRECT
ANSWER- ✔✔Vagus
Origination/Termintation points of parasympathetic nerve fibers - CORRECT ANSWER-
✔✔Medulla Oblongata/SA and AV node
Stimulation of parasympathetic nerve fibers _____ (slows or speeds up) FHR - CORRECT
ANSWER- ✔✔slows
Sympathetic nervous system termination point - CORRECT ANSWER- ✔✔Heart muscle
Stimulation of sympathetic nerve fibers cause: - CORRECT ANSWER- ✔✔Increase in HR
and stroke volume, which increase cardiac output
Chemoreceptors function - CORRECT ANSWER- ✔✔Found in the aortic arch and CNS,
respond to increased CO2 levels by stimulating vagus nerve to slow FHR, therefore
decreasing oxygen consumption
