Exam Questions with 100% Verified
Answers
A characteristic of variable decelerations is: - Answer ✓✓The onset of the deceleration
is abrupt

An increase in the fetal heart rate immediately preceding a variable deceleration is
caused by: - Answer ✓✓Occlusion of the umbilical vein

During a contraction, the tocodynamometer detects: - Answer ✓✓Pressure created by
tensing of uterine muscles

During a fetal sleep cycle, FHR variability is usually - Answer ✓✓minimal

Fetal heart rate vaiability is definded as fluctuations in the baseline that are irregular in -
Answer ✓✓AMPLITUDE and FREQUENCY

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: - Answer ✓✓mixed acidemia

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.

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.

, Maternal-fetal oxygen and nutrient transfer takes place in the - Answer ✓✓Placental
cotyledon

Normal fetal heart rate baseline is - Answer ✓✓110-160

Stimulation of the vagus nerve in a healthy fetus will cause: - Answer ✓✓a decrease in
fetal heart rate

The most highly oxygenated blood in fetal circulation is carried by: - Answer ✓✓Ductus
venosus

Umbilical arterial cord blood gas results are as follows
pH: 6.86
pCO2: 48
pO2: 4.2
BE: -23.7 - Answer ✓✓metabolic acidemia

uterine tachysystole is defined as - Answer ✓✓>5 contractions in 10 minutes averaged
over 30 minutes

When assessing a FHR tracing, the first step is to - Answer ✓✓Estabilish the baseline
rate

Which deceleration in the FHR is considered benign and does not require an
intervention to correct? - Answer ✓✓Early deceleration

Which of the following is an extrinsic influence on the FHR? - Answer ✓✓Fetal-
placental circulation

A comprehensive maternal-fetal physical assessment is necessary to assess maternal
oxygenation, build the maternal-fetal data base, and optimize clinical decisions. -
Answer ✓✓TRUE

A systematic assessment of the fetal heart rate tracing includes: - Answer ✓✓Baseline
rate, variability, periodic/episodic changes, uterine activity

Decreased umbilical blood flow stimulates the chemoreceptors and/or baroreceptors,
increasing catecholamine production leading to an increase in blood flow to the
essential organs, including: - Answer ✓✓-adrenals
-brain
-heart

Extrinsic influences of fetal heart rate patterns include: - Answer ✓✓Placenta, fetal-
placental circulation, umbilical cord
