AWHONN Intermediate Fetal Monitoring TEST (2022, 7th Ed.)
Which of the following is an extrinsic influence on the FHR? - ANSW C. Fetal-placental
circulation
The most highly oxygenated blood in fetal circulation is carried by: - ANSW C. Ductus venosus
If fetal arterial pressure begins to fall below normal levels: - ANSW A. Baroreceptors cause
vasoconstriction and increase the FHR
Fetal heart rate variability is defined as fluctuations in the baseline that are irregular in _____ and
_____. - ANSW B. Amplitude and frequency
An increase in the fetal heart rate immediately preceding a variable deceleration is caused by: -
ANSW A. Occlusion of the umbilical vein
When assessing a FHR tracing, the first step is to: - ANSW C. Establish the baseline rate
Which deceleration in the FHR is considered benign and does not require an intervention to
correct? - ANSW A. Early deceleration
If the umbilical vein is the only vessel occluded during cord compression - ANSW B.
Oxygenated blood may be restricted from being delivered to the fetus
During a fetal sleep cycle, FHR variability is usually ____. - ANSW C. Minimal
Uterine tachysystole is defined as: - ANSW B. >5 contractions in 10 mind over 30 minutes
Maternal-fetal oxygen and nutrient transfer takes place in the: - ANSW B. intervillous space
, During a contraction, the tocodynamometer detects: - ANSW A. Pressure created by tensing of
uterine muscle
Normal fetal heart rate baseline is: - ANSW 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: - ANSW C. Mixed acidemia
A characteristic of variable decelerations is: - ANSW B. The onset of the deceleration is abrupt
Stimulation of the vagus nerve in a healthy fetus will cause: - ANSW A. A decrease in the fetal
heart rate
What is the baseline rate? - ANSW B. 145 bpm
What is the correct interpretation? - ANSW B. Baseline of 160 bpm with recurrent late
decelerations
What is the primary physiologic goal? - ANSW B. Maximize oxygenation
Based on the tracing, the most appropriate interventions are: - ANSW B. Decrease oxytocin
from 14 to 7 mU/min and start a 500-mL IVFB.
Which of the following is a correct interpretation of the tracing? - ANSW C. The tracing of
uterine activity requires palpation for accurate assessment
Which of the following is an extrinsic influence on the FHR? - ANSW C. Fetal-placental
