If fetal arterial pressure begins to fall below normal levels:
- Correct Answer-A. BARORECEPTORS CAUSE VASOCONSTRICTION AND
INCREASE THE FHR
An increase in arterial blood pressure produces vessel distension and
causes arterial baroreceptors to send neuronal messages to the
cardioinhibitory center, which in turn causes rapid slowing of the fetal
heart rate via the parasympathetic vagus nerve. A decrease in arterial
pressure results in an increased heart rate.
Which of the following is an extrinsic influence on the FHR?
- Correct Answer-Fetal-placental circulation
Fetal heart rate vaiability is definded as fluctuations in the baseline that
are irregular in

- Correct Answer-AMPLITUDE and FREQUENCY
The most highly oxygenated blood in fetal circulation is carried by: -
Correct Answer-Ductus venosus
An increase in the fetal heart rate immediately preceding a variable
deceleration is caused by:
- Correct Answer-Occlusion of the umbilical vein
The etiology of variable decelerations is likely related to umbilical venous
and arterial occlusion. Initially, with occlusion of the thin-walled umbilical
vein, venous return to the fetal right atrium is reduced, producing a reflex
tachycardia. This pattern often is observed as a shoulder on the FHR
monitor strip immediately before the abrupt variable FHR deceleration
When assessing a FHR tracing, the first step is to
- Correct Answer-Estabilish the baseline rate
Which deceleration in the FHR is considered benign and does not require
an intervention to correct?
- Correct Answer-Early deceleration

If the umbilical vein is the only vessel occluded during cord compression
- Correct Answer-Deoxygenated blood cannot be removed from fetal
circulation
During umbilical cord compression, the vein on the umbilical cord
becomes compressed leading to CO2 (carbon dioxide) to accumulate in
your baby's blood, which produces respiratory acidosis.
During a fetal sleep cycle, FHR variability is usually - Correct Answer-
minimal
uterine tachysystole is defined as - Correct Answer->5 contractions in 10
minutes averaged over 30 minutes
Maternal-fetal oxygen and nutrient transfer takes place in the - Correct
Answer-Placental cotyledon
During a contraction, the tocodynamometer detects: - Correct Answer-
Pressure created by tensing of uterine muscles
Normal fetal heart rate baseline is - Correct Answer-110-160

Following birth, a fetal cord blood sample is taken. The results are:
pH: 6.95
pCO2: 86 mmHg
pO2: 4 mmHg
BE: -18.6 mEq/L
These results are best interpreted as: - Correct Answer-mixed acidemia
A characteristic of variable decelerations is: - Correct Answer-The onset
of the deceleration is abrupt
Stimulation of the vagus nerve in a healthy fetus will cause: - Correct
Answer-a decrease in fetal heart rate
Umbilical arterial cord blood gas results are as follows
pH: 6.86
pCO2: 48
pO2: 4.2
BE: -23.7 - Correct Answer-metabolic acidemia
