Questions: A 20-year-old GOP0 woman with no significant medical history is concerned about becoming pregnant. She had sexual intercourse with her boyfriend last night and usually uses a cervical diaphragm for contraception. However, she forgot to place her diaphragm in last night and is now seeking emergency contraception. She also wants to prevent this situation from happening again. Which of the following is the best option for this patient for emergency contraception? A. Implanon B. Copper intrauterine device C. Medroxyprogesterone D. Oral contraceptive pills

The answer is B: Copper intrauterine device.

Explanation for each option:

A. Implanon: Implanon is a type of long-acting reversible contraception (a hormonal implant) that is used for ongoing prevention of pregnancy. It is not used for emergency contraception.

B. Copper intrauterine device (IUD): The copper IUD is one of the most effective forms of emergency contraception if inserted within five days after unprotected intercourse. It works by preventing fertilization and can also provide long-term contraception, making it a suitable option for this patient who wants to prevent future incidents.

C. Medroxyprogesterone: This is a form of hormonal contraception typically used as an injection for long-term birth control. It is not used for emergency contraception.

D. Oral contraceptive pills: While certain oral contraceptive pills can be used as emergency contraception (often referred to as the "morning-after pill"), they are generally less effective than a copper IUD for emergency contraception.

In summary, the copper IUD is the best option for this patient as it provides effective emergency contraception and can also serve as a long-term contraceptive method.
