AWHONN INTERMEDIATE FETAL MONITORING TEST
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
