Which condition is most commonly associated with late decelerations of the fetal heart rate?

  • A. Head compression
  • B. Maternal hypothyroidism
  • C. Uteroplacental insufficiency
  • D. Umbilical cord compression
Correct Answer: C

Rationale: Late decelerations of the fetal heart rate are most commonly associated with uteroplacental insufficiency. During contractions, there is reduced blood flow to the placenta, leading to hypoxia and acidosis in the fetus, resulting in late decelerations. Head compression (A) typically causes early decelerations. Maternal hypothyroidism (B) does not directly affect fetal heart rate. Umbilical cord compression (D) can cause variable decelerations, not late decelerations. Therefore, the correct answer is C.
