A 25-year-old woman is visiting the prenatal clinic and shares with the nurse her desire to go "natural" with her pregnancy. She shows the nurse a list of herbal remedies that she wants to buy so that she can "avoid taking any drugs." Which statement by the nurse is correct?

Choice A reason: Herbal remedies lack FDA safety data; in pregnancy, untested substances risk fetal harm (e.g., teratogenicity), making this a critical caution. Choice B reason: Claiming safety is false; many herbs (e.g., St. John’s Wort) affect pregnancy adversely, and without evidence, this misleads the patient dangerously. Choice C reason: Consistency isn’t required; herbal products vary widely in potency, and this false assurance ignores regulatory gaps in supplement standardization. Choice D reason: Labels help, but warnings are inconsistent; this shifts responsibility without addressing the lack of proven safety, a more pressing prenatal concern.
