Question 1 of 5
A nurse is assisting with the preparation of an educational program about the use of oral contraceptives. The nurse should include that which of the following herbal supplements reduces the effectiveness of oral contraceptives?
Correct Answer: B
Rationale: The correct answer is B: St. John's wort. St. John's wort is known to induce drug-metabolizing enzymes, potentially reducing the effectiveness of oral contraceptives. It can decrease the blood levels of estrogen and progesterone, making the contraceptives less effective. Ginger root (
A), Gingko biloba (
C), and Glucosamine (
D) do not have known interactions with oral contraceptives. St. John's wort is the only choice that directly impacts the effectiveness of oral contraceptives.
