NCC C-EFM Study Guide
Causes of fetal heart rate (FHR) changes not related directly to fetal
oxygenation can include fetal sleep cycles, extreme prematurity, and maternal
conditions such as:
a. fever and infection
b. medication and positioning
c. substance abuse and fever - correct answer ✔a. fever and infection
are maternal conditions that can affect the fetal heart rate without being
related to fetal oxygenation.
Medication can trigger nonhypoxic changes in fetal heart rate, but maternal
conditions such as positioning can cause hypoxia through umbilical cord
compression.
Maternal substance abuse could lead to hypoxia while a maternal fever is
associated with nonhypoxic fetal heart rate changes
The mechanism for placental transport of oxygen and carbon dioxide is
a. active transport
b. facilitated diffusion
c. passive diffusion - correct answer ✔c. passive diffusion

test. The original finding would be considered
a. equivocal
b. false negative
c. false positive - correct answer ✔b. false negative
, According to Murta and colleagues, elevates arginine vasopressin levels are
implicated in
a. saltatory patterns
b. sinister heart patterns
c. sinosoidal patterns - correct answer ✔c. sinosoidal patterns
A saltatory pattern which shows excessive fetal heart rate variability in brief
intervals is indicative of
a. compensation
b. deterioration
c. mild hypoxic stress - correct answer ✔c. mild hypoxic stress
The quantification of bradycardia is based on
a. actual fetal heart rate in beats per minute
b. average of the baseline rate in ten minute period
c. duration of time the heart rate is below 90 - correct answer ✔a. actual fetal
heart rate in beats per minute
Studies have shows pulse oximetry as an adjunct surveillance method has
what impact on the incidence of cesarean deliveries?
a. decreases the rate
b. has no effect
c. requires more study - correct answer ✔b. has no effect

rate tracing is
a. heart block
b. sleep
