A nurse is instructing a pregnant patient concerning the potential risk to her fetus from a pregnancy category B drug.
What would the nurse inform the patient?
There is evidence of human fetal risk, but the potential benefits from the use of the drug may be acceptable despite potential risks.
Animal studies have shown an adverse effect on the fetus, but there are no adequate studies in pregnant women.
Adequate studies in pregnant women have demonstrated that there is no risk to the fetus.
Animal studies have not demonstrated a risk to the fetus, but there have been no adequate studies in pregnant women.
The Correct Answer is D
Choice A rationale
Evidence of human fetal risk would categorize the drug as Category D or X, not Category B.
Choice B rationale
This statement aligns more with Category C drugs, where animal studies show adverse effects, but not Category B.
Choice C rationale
This describes Category A drugs, not Category B.
Choice D rationale
Category B drugs have shown no risk in animal studies but lack adequate human studies, fitting this description.

Correct Answer is B
Explanation
Choice A rationale
Generic medications are equivalents to brand name drugs and are not typically a priority query unless there's an issue of consistency in medication use.
Choice B rationale
Over-the-counter (OTC) medications can interact with prescription medications or have side effects, so it’s crucial to know if a patient is taking any.
Choice C rationale
This question is important for women who are pregnant but is not the primary concern when assessing general medication use.
Choice D rationale
Orphan drugs are used to treat rare conditions and are less likely to be encountered in a general assessment.
Correct Answer is C
Explanation
Choice A rationale
Class I antiarrhythmic drugs block sodium channels, affecting phase 0 of the action potential, not phase 3.
Choice B rationale
Class IV antiarrhythmic drugs block calcium channels, which affects phase 2 of the action potential and slows heart rate and conduction.
Choice C rationale
Class III antiarrhythmic drugs block potassium channels, prolonging phase 3 of the action potential. This results in a prolonged repolarization period, reducing the risk of arrhythmia.
Choice D rationale
Class II antiarrhythmic drugs are beta-blockers that primarily affect phase 4 of the action potential, reducing heart rate and conduction, but they do not block potassium channels.
