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
The most highly oxygenated blood in fetal circulation is carried by: -
ANSWER✅✅✅✅Ductus venosus
An increase in the fetal heart rate immediately preceding a variable deceleration is
caused by: -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 -ANSWER✅✅✅✅Estabilish the
baseline rate
