Which of the following is a characteristic of an ominous periodic change in the fetal heart rate?
Correct answer
D
Rationale
A recurrent fetal heart rate of 90-100 bpm at the end of contractions (late decelerations) is ominous indicating fetal hypoxia from uteroplacental insufficiency. Normal heart rate (120-130) variability and accelerations are reassuring findings.
