A client is scheduled to receive mifepristone (Mifeprex) to end a pregnancy and asks the nurse how the medication works. What should the nurse respond?
Standard Text: Select all that apply.
1. "It blocks progesterone, which is needed to maintain the pregnancy."
2. "It sensitizes the uterus to the effects of prostaglandins."
3. "It causes a large amount of prostaglandin to be released and start uterine contractions."
4. "It blocks ovulation from occurring."
5. "It increases the amount of estrogen in your body."
Correct Answer: 2,3
Rationale 1: This explains how the medication works to prevent pregnancy, not to end a pregnancy.
Rationale 2: This medication increases the synthesis of prostaglandins and sensitizes the uterus to their effects.
Rationale 3: This medication promotes increased uterine contractions, which expel the embryo from the uterus.
Rationale 4: This medication does not block ovulation.
Rationale 5: This medication does not increase the amount of estrogen in the body.
Global Rationale: This medication increases the synthesis of prostaglandins and sensitizes the uterus to their effects. It also promotes increased uterine contractions, which expel the embryo from the uterus. It is a progesterone blocker, but this explains how the medication works to prevent pregnancy, not how it ends pregnancy. It does not block ovulation and does not increase the amount of estrogen in the body.
