Which contraceptive must be replaced every three weeks?

• A. NuvaRing
• B. Levonorgestrel intrauterine system
• C. Levonorgestrel implant
• D. Spermicidal suppositories

Answer: (A)

Replacement schedule is being tested here: the method that must be replaced every three weeks is the vaginal ring. It stays in place for three weeks to continuously release hormones, then is removed and a new ring is inserted for another three-week cycle, with a one-week ring-free interval in between. The other options are long-acting or per-use methods: the levonorgestrel intrauterine system lasts several years and is not replaced on a weekly basis; the levonorgestrel implant also provides years of contraception; spermicidal suppositories are used at each act of intercourse and don’t have a fixed three-week replacement cycle.
