A nurse is providing teaching to a client who is postpartum and interested in information about contraception. Which of the following instructions should the nurse include?

Choice A reason: The lactation amenorrhea method is effective only up to 6 months postpartum, and only if exclusive breastfeeding and amenorrhea are maintained. It is not reliable for 12 months, so this statement is inaccurate, making it incorrect for contraception teaching. Choice B reason: Placing the transdermal contraceptive patch on the upper arm or back ensures proper adhesion and absorption. This aligns with manufacturer guidelines for effective contraception, making it a correct and appropriate instruction for postpartum clients seeking reliable methods. Choice C reason: A diaphragm used before pregnancy may no longer fit due to pelvic changes post-delivery. It requires refitting 6 weeks postpartum, so continuing use without adjustment is ineffective and risky, making this incorrect. Choice D reason: Starting oral contraceptives immediately after delivery is not recommended, especially for breastfeeding mothers, due to risks like reduced milk supply or thromboembolism. Initiation typically begins 3-6 weeks postpartum, making this incorrect and unsafe.
