Correct Answer is C

Explanation

Choice A rationale

A reaction from an epidural can cause side effects such as hypotension and shivering, but it is not related to tachysystole.

Choice B rationale

When the fetus's heart rate drops below baseline, it is termed bradycardia, not tachysystole. This condition can occur due to various reasons, including cord prolapse or placental insufficiency.

Choice C rationale

Tachysystole is defined as more than five contractions in 10 minutes. This condition can lead to reduced blood flow to the fetus, resulting in fetal distress.

Choice D rationale

Pitocin is a medication used to induce labor and can cause tachysystole, but the administration of Pitocin itself is not the definition of tachysystole. It's the increased frequency of contractions that defines the condition.

Correct Answer is A

Explanation

Choice A rationale

Uterine atony is a common complication following polyhydramnios because the excessive amniotic fluid can lead to uterine overdistension, which in turn can cause poor uterine

muscle tone and increased risk of postpartum hemorrhage.

Choice B rationale

Thrombophlebitis is an inflammation of a vein with clot formation, but it is not directly associated with polyhydramnios.

Choice C rationale

Postpartum preeclampsia is high blood pressure and signs of organ damage after delivery, but there is no direct link between polyhydramnios and this condition.

Choice D rationale

Retained placental fragments can lead to postpartum hemorrhage but are not specifically associated with polyhydramnios.
