The nurse understands that variability in the FHR is indicative of which of the following?
Decreased oxygenation of the placenta
A working fetal nervous system
Pressure on the umbilical cord
Fetal distress due to head compression
The Correct Answer is B
A. Decreased oxygenation of the placenta:
Opposite-this would reduce variability.
B. A working fetal nervous system:
Moderate variability is a reassuring sign of intact CNS and good oxygenation.
C. Pressure on the umbilical cord:
Causes variable decelerations, not variability in baseline.
D. Fetal distress due to head compression:
This can cause early decelerations but not baseline variability.
