A nurse is instructing a pregnant patient concerning the potential risk to her fetus from a Pregnancy Category B drug. The nurse would inform the patient that:
Correct answer
A
Rationale
The correct answer is A. Pregnancy Category B drugs are those for which animal reproduction studies have not shown a risk to the fetus, but there are no adequate and well-controlled studies in pregnant women. This means that while animal studies have not demonstrated harm, the potential risks to the fetus in humans are unknown. Choice B is incorrect because it states that there is no risk, which is not supported by data. Choice C is incorrect as it suggests there is evidence of fetal risk, which contradicts the definition of Pregnancy Category B. Choice D is incorrect because it states that animal studies have shown adverse effects, which is not true for Category B drugs.
