A nurse is providing discharge teaching about postpartum contraception for a client who is breastfeeding and wishes to begin using contraceptive immediately. Which of the following methods should the nurse discuss with the client?

A. Progestin oral contraceptive: Progestin-only oral contraceptives (often called the “mini-pill”) are safe to use immediately postpartum for breastfeeding clients because they do not affect milk production. They provide effective contraception without the risks associated with estrogen-containing methods. B. Vaginal etonogestrel/ethinyl estradiol contraceptive ring: Combination estrogen-progestin contraceptives, such as the vaginal ring, are generally not recommended immediately postpartum for breastfeeding clients because estrogen can reduce milk supply and may increase the risk of thromboembolism. C. Transdermal estrogen/progesterone patch: Similar to other estrogen-containing methods, the transdermal patch is not recommended immediately postpartum for breastfeeding clients due to potential interference with lactation and increased thromboembolism risk. D. Injectable synthetic progestin: Injectable progestin (e.g., depot medroxyprogesterone acetate) is safe for breastfeeding, but it is not ideal for immediate postpartum use if the client wishes for rapid return to fertility later, since its effects can last for several months. It may also have delayed effects on bone density with long-term use.
