Which deceleration in the FHR is considered benign and does not require an
intervention to correct?
A. Early deceleration
If the umbilical vein is the only vessel occluded during cord compression
B. Oxygenated blood may be restricted from being delivered to the fetus
During a fetal sleep cycle, FHR variability is usually ____.
C. Minimal
Uterine tachysystole is defined as:
B. >5 contractions in 10 mind over 30 minutes
Maternal-fetal oxygen and nutrient transfer takes place in the:
B. intervillous space
,During a contraction, the tocodynamometer detects:
A. Pressure created by tensing of uterine muscle
Which of the following is an extrinsic influence on the FHR?
C. Fetal-placental circulation
The most highly oxygenated blood in fetal circulation is carried by:
C. Ductus venosus
If fetal arterial pressure begins to fall below normal levels:
A. Baroreceptors cause vasoconstriction and increase the FHR
Fetal heart rate variability is defined as fluctuations in the baseline that are
irregular in _____ and _____.
B. Amplitude and frequency
,An increase in the fetal heart rate immediately preceding a variable deceleration is
caused by:
A. Occlusion of the umbilical vein
When assessing a FHR tracing, the first step is to:
C. Establish the baseline rate
Normal fetal heart rate baseline is:
C. 110-160 bpm
Following birth, a fetal cord blood sample is taken. The results are:
pH: 6.95
