An OB nurse is educating a new graduate nurse about the signs and symptoms of a hydatidiform mole.
The new graduate nurse understands the teaching when he identifies the expected assessment findings with this condition.
Which of the following signs and symptoms would the nurse identify?

Choice A rationale

Placenta previa is characterized by painless, bright red vaginal bleeding in the third trimester, not by low hemoglobin and platelet levels.

Choice B rationale

Abruptio placentae involves painful vaginal bleeding, uterine tenderness, and contractions, and is not primarily associated with low hemoglobin and platelet counts.

Choice C rationale

Gestational hypertension is identified by high blood pressure without proteinuria or severe systemic symptoms, and typically doesn't lead to low platelet counts or hemoglobin levels.

Choice D rationale

Preeclampsia includes hypertension, proteinuria, and systemic symptoms like low platelet count and hemoglobin level, indicating a more severe form such as HELLP syndrome.

Choice A rationale

While rupturing membranes can be a concern, the primary issue with a vaginal exam in the presence of placenta previa is the risk of severe bleeding. This choice is partially correct but not the most accurate answer.

Choice B rationale

With placenta previa, the placenta covers the cervix, and a vaginal exam could easily disrupt it, leading to significant vaginal bleeding. This bleeding can be dangerous for both the mother and the baby, making this the most accurate reason to avoid a vaginal exam.

Choice C rationale

Infection risk is a concern with any invasive procedure, but it is not the primary reason to avoid a vaginal exam in the case of placenta previa. The main concern is the risk of bleeding.

Choice D rationale

Initiating preterm labor is a possible risk with any vaginal exam late in pregnancy, but it is not the primary concern in cases of placenta previa. The main issue is the potential for causing severe bleeding.
