If fetal arterial pressure begins to fall below normal levels: - 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? - ANSWER-Fetal-placental
circulation
Fetal heart rate vaiability is definded as fluctuations in the baseline that are irregular in -
ANSWER-AMPLITUDE and FREQUENCY
Which deceleration in the FHR is considered benign and does not require an intervention to
correct? - ANSWER-Early deceleration
If the umbilical vein is the only vessel occluded during cord compression - 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.
