AWHONN Intermediate Fetal Monitoring
QUESTIONS & ANSWERS RATED 100% CORRECT
1. Which of the following is an extrinsic influence
on the FHR?
2. The most highly oxygenated blood in fetal ductus venosus
circulation is carried by
3. If fetal arterial pressure begins to fall below baroreceptors cause
normal levels vaso- constriction and
increase FHR
4. Fetal heart rate variability is defined as amplitude and
fluctuations in the baseline that are frequency
irregular in and
.
5. An increase in FHR immediately preceding a occlusion of the umbilical
variable 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 early deceleration
benign and does not require an intervention
to correct?
8. If the umbilical vein is the only vessel occluded during oxygenated
blood may be
cord restricted from being de-
compression 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

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 a decrease in the FHR
fetus will 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 labor. She
physiologic goal? is 4
cm/80%/-
20. Assess the tracing. The patient is a 20-year- 1 and the
