AWHONN Intermediate Fetal Monitoring
TEST (Answered 100% Correctly)
Updated 2025
1. Which of the following is an extrinsic influence on the FHR? Ans C. Fetal-
placen- tal circulation
2. The most highly oxygenated blood in fetal circulation is carried by
Ans C. Ductus venosus
3. If fetal arterial pressure begins to fall below normal levels Ans A.
Baroreceptors cause vasoconstriction and increase the FHR
4. Fetal heart rate variability is defined as fluctuations in the baseline that are
irregular in and . Ans B. Amplitude and frequency
5. An increase in the fetal heart rate immediately preceding a variable decel-
eration is caused by Ans A. Occlusion of the umbilical vein
6. When assessing a FHR tracing, the first step is to Ans C. Establish the
baseline rate
7. Which deceleration in the FHR is considered benign and does not require
an intervention to correct? Ans A. Early deceleration

, 8. If the umbilical vein is the only vessel occluded during cord compression
Ans B. Oxygenated blood may be restricted from being delivered to the fetus
9. During a fetal sleep cycle, FHR variability is usually . Ans C. Minimal
10. Uterine tachysystole is defined as Ans B. >5 contractions in 10 mind
over 30 minutes
11. Maternal-fetal oxygen and nutrient transfer takes place in the Ans B.
intervil- lous space
12. During a contraction, the tocodynamometer detects Ans A. Pressure
created by tensing of uterine muscle
13. Normal fetal heart rate baseline is Ans C. 110-160 bpm
14. Following birth, a fetal cord blood sample is taken. The results are
Ans pH 6.95
pCO2 86 mmHg
pO2 4mmHg BE
-18.6 mEq/L
These results are best interpreted as Ans C. Mixed acidemia
15. A characteristic of variable decelerations is Ans B. The onset of the
deceleration is abrupt
16. Stimulation of the vagus nerve in a healthy fetus will cause Ans A. A
decrease in the fetal heart rate
17. What is the baseline rate? Ans B. 145 bpm
18. What is the correct interpretation? Ans B. Baseline of 160 bpm with recurrent
late decelerations
19. What is the primary physiologic goal? Ans B. Maximize oxygenation
