Question

which statement accurately describes emergency contraceptives?
multiple choice

• emergency contraceptives reduce the chance that an ovum will be fertilized.
• emergency contraceptives are considered abortogenic agents.
• emergency contraceptives are most effective when taken within 96 hours of unprotected vaginal intercourse.
• progesterone - only emergency contraception requires a prescription.

Explanation:

Emergency contraceptives work by preventing or delaying ovulation, thickening cervical mucus to block sperm, or interfering with fertilization—thus reducing the chance of ovum fertilization. They are not abortogenic (do not terminate established pregnancies), most effective within 72 hours (not 96), and progesterone-only options like Plan B are available over-the-counter without a prescription.

Answer:

Emergency contraceptives reduce the chance that an ovum will be fertilized.
