An adolescent patient calls the office and asks to speak with the nurse. The patient cannot remember where she can place her contraceptive patch. What area of the body should the nurse tell her to avoid?

Correct Answer: A

Rationale: The nurse should advise the adolescent patient to avoid placing the contraceptive patch on her breasts. The contraceptive patch is typically recommended to be placed on areas of the body with minimal hair and movement to ensure proper adherence and absorption of hormones. Placing the patch on the breasts may result in movement and friction, causing it to become dislodged or less effective. It is important to follow the specific instructions provided with the contraceptive patch on where to apply it for optimal effectiveness.

Correct Answer: D

Rationale: The LNG-IUC, or levonorgestrel-releasing intrauterine system, works primarily by thickening the cervical mucus, which inhibits the passage of sperm through the cervix. This mechanism reduces the likelihood of fertilization occurring. Additionally, LNG-IUC also causes atrophic changes in the endometrium, which makes it less conducive for implantation of a fertilized egg, further decreasing the chance of pregnancy.

Correct Answer: D

Rationale: The education the nurse should provide to a person taking Ella for emergency contraception is to restart their COCs the next day and use a backup method, such as condoms, for 7 days. This is important to ensure continued protection against pregnancy, as Ella may potentially reduce the effectiveness of the COCs. Using a backup method during this time is essential to prevent unintended pregnancy.

Correct Answer: C

Rationale: Copper intrauterine devices (IUDs) have the best efficacy for prevention of pregnancy among emergency contraception options. Copper IUDs are over 99% effective when used as emergency contraception, making them more reliable than other methods like Plan B, Yuzpe, or progesterone-only EC. This high efficacy is due to the mechanism of action of copper IUDs, which prevent fertilization and implantation of the fertilized egg. Additionally, once inserted, a copper IUD can continue to provide ongoing contraception for up to 10 years, making it a long-term contraceptive option as well.

Correct Answer: B

Rationale: The important information provided regarding male sterilization (vasectomy) is that the individual will need to return to the office to check for sperm in their ejaculate after the procedure. This is essential to ensure that the vasectomy was successful in achieving sterility. It typically takes a few months and a certain number of ejaculations for all remaining sperm to be cleared from the reproductive tract, so a follow-up test is necessary to confirm sterility.
