What does the nurse know about postcoital emergency contraception with Ella or Next Choice?

A. Requires that the first dose be taken within 72 hours of unprotected intercourse: While some emergency contraceptives like Plan B are most effective within 72 hours, Ella (ulipristal acetate) can be effective up to 120 hours after unprotected intercourse, so the 72-hour limitation does not apply universally. B. Requires that the woman take second and third doses at 24 and 36 hours after the first dose: This dosing schedule applies to older multi-dose regimens of levonorgestrel, not to single-dose emergency contraceptives like Ella or the one-dose Next Choice, which do not require multiple follow-up doses. C. Must be taken in conjunction with an IUD insertion: Emergency contraceptive pills function independently to prevent ovulation or fertilization and do not require an IUD insertion. IUDs can also be used as emergency contraception, but they are a separate method. D. Most states require the woman to have a valid prescription: Ella is prescription-only in many states, and the requirement for a prescription differentiates it from over-the-counter emergency contraceptives like Plan B, making this the accurate regulatory consideration for its use.
