C-EFM Review
The tocotransducer produces all of the following information except:
a. frequency and duration of contractions
b. interval and timing of contractions
c. intensity and resting tone of the uterus - correct answer ✔c. intensity and
resting tone of the uterus
Rationale: Nurses can provide the frequency and duration but are unable to
obtain intensity and resting tone.
One limitation of the direct fetal electrode is:
a. There will always be a localized fetal infection at the site of application.
b. The mother must be in active labor before it can be applied.
c. It may record maternal heart rate (MHF) when there is a fetal demise. -
correct answer ✔c. It may record maternal heart rate (MHF) when there is a
fetal demise.
Rationale: With a demise, the maternal heartbeat can still be obtained from
the fetus. Nurses only need ROM to apply a scalp electrode and only enough
dilatation to reach the scalp. Fortunately, localized infections are rare.
Signal ambiguity occurs most frequently after:
a. during pushing when the maternal heart rate (MHR) rises more closely to
the fetal baseline
b. rupture of membranes
c. twin gestation monitoring - correct answer ✔a. during pushing when the
maternal heart rate (MHR) rises more closely to the fetal baseline
Rationale: Signal ambiguity can be seen when the mom's heart rate becomes
tachycardic with the work of pushing. If there is an acceleration with pushing,
, suspect MHR because most babies are more likely to have a deceleration due
to a vagal response.
Degenerative changes of the placenta can occur due to:
a. maternal migraines
b. Class C diabetes
c. poor maternal nutrition - correct answer ✔b. Class C diabetes
Rationale: Diabetes is the only condition known to cause calcifications in the
placenta.
Simple diffusion includes all of the following except:
a. oxygen
b. uric acid
c. glucose - correct answer ✔c. glucose
Rationale: Glucose needs facilitated transport for transfer.
The umbilical artery carries:
a. oxygenated blood to the fetus
b. important nutrients for fetal growth
c. deoxygenated blood from the fetus - correct answer ✔c. deoxygenated
blood from the fetus
Rationale: The artery causes deoxygenated blood to the fetus.
Extrinsic influences on the fetal heart rate (FHR) regulatory system include:
a. uterine blood flow
b. fetal circulatory system
c. oxygenation of the tissues - correct answer ✔a. uterine blood flow
