Final answer:
Uteroplacental insufficiency and late decelerations can be caused by maternal hypotension and/or uterine hyperstimulation, which reduces blood flow to the placenta.
Step-by-step explanation:
The conditions that might cause uteroplacental insufficiency and late decelerations are primarily associated with factors that reduce blood flow to the placenta, thereby compromising the transfer of oxygen and nutrients to the fetus. The correct answer to which conditions might cause uteroplacental insufficiency and late decelerations is d) Maternal hypotension. Maternal hypotension can lead to reduced placental blood flow, resulting in insufficient oxygen and nutrients reaching the fetus and potentially causing late decelerations. Other factors that can contribute to uteroplacental insufficiency include uterine hyperstimulation, where excessive contractions, often due to medications used to induce labor, can lead to reduced placental blood flow.
