AWHONN Intermediate Fetal Monitoring TEST
Terms in this set (50)
Which of the following is an C. Fetal-placental circulation
extrinsic influence on the
FHR?
The most highly C. Ductus venosus
oxygenated blood in fetal
circulation is carried by:
If fetal arterial pressure A. Baroreceptors cause vasoconstriction and increase
begins to fall below normal the FHR
levels:
Fetal heart rate variability is B. Amplitude and frequency
defined as fluctuations in
the baseline that are
irregular in _____ and _____.
An increase in the fetal A. Occlusion of the umbilical vein
heart rate immediately
preceding a variable
deceleration is caused by:
When assessing a FHR C. Establish the baseline rate
tracing, the first step is to:
Which deceleration in the A. Early deceleration
FHR is considered benign
and does not require an
intervention to correct?
If the umbilical vein is the B. Oxygenated blood may be restricted from being
only vessel occluded delivered to the fetus
during cord compression
, During a fetal sleep cycle, C. Minimal
FHR variability is usually ____.
Uterine tachysystole is B. >5 contractions in 10 mind over 30 minutes
defined as:
Maternal-fetal oxygen and B. intervillous space
nutrient transfer takes place
in the:
During a contraction, the A. Pressure created by tensing of uterine muscle
tocodynamometer detects:
Normal fetal heart rate C. 110-160 bpm
baseline is:
Following birth, a fetal cord C. Mixed acidemia
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:
A characteristic of variable B. The onset of the deceleration is abrupt
decelerations is:
Stimulation of the vagus A. A decrease in the fetal heart rate
nerve in a healthy fetus will
cause:
What is the baseline rate? B. 145 bpm
What is the correct B. Baseline of 160 bpm with recurrent late decelerations
interpretation?
What is the primary B. Maximize oxygenation
physiologic goal?
