AWHONN INTERMEDIATE FETAL MONITORING EXAM WITH VERIFIED
QUESTIONS AND ANSWERS WITH GUARANTEED SUCCESS
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
