Question 4 of 5
A nurse is discussing various ways to obtain a medical abortion with a patient. Which statement by the patient best demonstrates understanding of mifepristone (RU 486) [Mifeprex]? 'This drug is most effective if I use it:'
Correct Answer: C
Rationale: Mifepristone (RU 486) is a progesterone antagonist used for medical abortion, most effective within 7 weeks of conception (gestational age), as it disrupts pregnancy maintenance. Earlier use (A, B, D) lacks a confirmed pregnancy or sufficient progesterone activity to target, making option C the correct understanding.
Question 5 of 5
