1. Which of the following is an extrinsic influence on the
FHR?
2. The most highly oxygenated blood in fetal circulation ductus venosus
is carried by
3. If fetal arterial pressure begins to fall below normal baroreceptors cause vaso-
levels constriction and increase
FHR
4. Fetal heart rate variability is defined as fluctuations amplitude and frequency
in the baseline that are irregular in _________ and
__________.
5. An increase in FHR immediately preceding a variable occlusion of the umbilical
deceleration is caused by: vein
6. When assessing a FHR tracing, the first step is to establish a baseline rate
7. Which deceleration in the FHR is considered benign early deceleration
and does not require an intervention to correct?
8. If the umbilical vein is the only vessel occluded during oxygenated blood may be
cord compression restricted from being de-
livered to the fetus
9. During fetal sleep cycle, FHR variability is usually minimal
10. Uterine tachysystole is defined as < 5 contractions in 10
minutes averaged over 30
minutes
11. Maternal-fetal oxygen and nutrient transfer takes intervillous space
place in the

12. During a contraction, the toco detects pressure created by the
tensing of uterine muscles
13. Normal FHR baseline is 110-160
14. Following birth, a fetal cord blood sample is taken. The mixed acidemia
results are:
pH: 6.95
pCO2: 86 mmHg
pO2: 4 mmHg
BE: -18.6 mEq/L
These results are best interpreted as:
15. A characteristic of variable decelerations is: the onset of the decelera-
tion is abrupt
16. stimulation of the vagus nerve in a healthy fetus will a decrease in the FHR
cause
17. Assess the tracing. What is the baseline rate? 145
18. Assess the tracing. What is the correct interpretation? Baseline of 160bpm with
recurrent late decelera-
tions
19. Assess the tracing: what is the primary physiologic maximize oxygenation
goal?
20. Assess the tracing. The patient is a 20-year-old G1 Decrease oxytocin from 14
at 41 weeks undergoing induction of labor. She is to 7 mU/min and start a
4 cm/80%/-1 and the oxytocin dose is currently 14 500-mL IVFB.
mU/min. Based on the tracing, the most appropriate
interventions are:
