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
A fetal death occurred less than a week after a negative contraction stress 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
A tracing shows fetal bradycardia. The most likely cause for this fetal heart rate tracing
is
a. heart block
b. sleep
c. traumatic brain injury - Correct Answer ✔✔ a. heart block
Many severely anemic. Rh-affected fetuses do not have a sinusoidal pattern but do
have a round blunted pattern and
a. absent accelerations
b. magnified variability peaks
c. fixed baseline rate - Correct Answer ✔✔ a. absent accelerations
The STAN system of fetal monitoring persons a computer analysis of the fetal ECG
specific to the detection of changes in the
a. QRS amplitude
b. R-R interval
c. ST segment - Correct Answer ✔✔ c. ST segment
A prolonged deceleration resulting in a new baseline bradycardia may result from vagal
activity in response to fetal
a. anemia
b. heart block
c. hypoxia - Correct Answer ✔✔ c. hypoxia
Studies have shown that in the low risk population, electronic fetal monitoring vs.
auscultation regarding the incidence of perinatal mortality is
a. higher
b. lower
c. the same - Correct Answer ✔✔ c. the same
When the amplitude range of FHR is undetectable, it would be documented as
a. absent
b. decreased
c. indeterminate - Correct Answer ✔✔ a. absent
