Which of the following is an extrinsic influence on the FHR? - ANSWer-C. Fetal-placental circulation
The most highly oxygenated blood in fetal circulation is carried by: - ANSWer-C. Ductus venosus
If fetal arterial pressure begins to fall below normal levels: - ANSWer-A. Baroreceptors cause
vasoconstriction and increase the FHR
Fetal heart rate variability is defined as fluctuations in the baseline that are irregular in _____ and
_____. - ANSWer-B. Amplitude and frequency
An increase in the fetal heart rate immediately preceding a variable deceleration is caused by: -
ANSWer-A. Occlusion of the umbilical vein
When assessing a FHR tracing, the first step is to: - ANSWer-C. Establish the baseline rate
Which deceleration in the FHR is considered benign and does not require an intervention to correct? -
ANSWer-A. Early deceleration
If the umbilical vein is the only vessel occluded during cord compression - ANSWer-B. Oxygenated
blood may be restricted from being delivered to the fetus
During a fetal sleep cycle, FHR variability is usually ____. - ANSWer-C. Minimal
, Uterine tachysystole is defined as: - ANSWer-B. >5 contractions in 10 mind over 30 minutes
Maternal-fetal oxygen and nutrient transfer takes place in the: - ANSWer-B. intervillous space
During a contraction, the tocodynamometer detects: - ANSWer-A. Pressure created by tensing of
uterine muscle
Normal fetal heart rate baseline is: - ANSWer-C. 110-160 bpm
Following birth, a fetal cord blood sample is taken. The results are:
pH: 6.95
pCO2: 86 mmHg
pO2: 4mmHg
BE: -18.6 mEq/L
These results are best interpreted as: - ANSWer-C. Mixed acidemia
A characteristic of variable decelerations is: - ANSWer-B. The onset of the deceleration is abrupt
Stimulation of the vagus nerve in a healthy fetus will cause: - ANSWer-A. A decrease in the fetal
heart rate
What is the baseline rate? - ANSWer-B. 145 bpm
What is the correct interpretation? - ANSWer-B. Baseline of 160 bpm with recurrent late
decelerations
What is the primary physiologic goal? - ANSWer-B. Maximize oxygenation
