A client presents to the health care clinic for her first prenatal checkup.
What nutritional supplement should the nurse discuss with the client to prevent neural tube defects in the developing fetus?

The correct answer is choice D.

Choice A rationale:

While oxytocin sensitivity is important for labor, there is no evidence to suggest that Braxton Hicks contractions increase oxytocin sensitivity.

Choice B rationale:

Prostaglandins play a crucial role in labor by causing the cervix to soften and dilate and the uterus to contract. However, there is no evidence to suggest that Braxton Hicks contractions increase the release of prostaglandins.

Choice C rationale:

While maternal comfort is important during labor, there is no evidence to suggest that Braxton Hicks contractions make maternal breathing easier.

Choice D rationale:

Braxton Hicks contractions help in softening and ripening the cervix, which is an important part of preparing for labor.

The correct answer is choice D.

Choice A rationale:

This statement describes the second stage of labor, not the third. The second stage begins with full cervical dilation and ends with the delivery of the fetus.

Choice B rationale:

The third stage of labor does not end 48 hours after the delivery of the placenta. This choice is incorrect.

Choice C rationale:

While it’s important to ensure no placental fragments remain, the third stage of labor technically ends with the delivery of the placenta, not at this later point.

Choice D rationale:

This is the correct definition of the third stage of labor. It begins with the delivery of the fetus and ends with the delivery of the placenta.
