A nurse is providing teaching to a client who has a new prescription for oral contraceptives (OCs).

Which of the following statements by the client indicates an understanding of how to initiate OCs?

The correct answer is choice B. It creates a local inflammatory response that impairs implantation.This means that the IUD makes the lining of the uterus less suitable for a fertilized egg to attach to it.

Choice A is wrong because it describes how hormonal IUDs work, not copper IUDs.Hormonal IUDs release hormones that thicken cervical mucus and prevent ovulation.

Choice C is wrong because it describes how tubal ligation works, not IUDs.Tubal ligation is a surgical procedure that blocks or cuts the fallopian tubes, which prevents sperm from reaching an egg.

Choice D is wrong because it implies that all of the above choices are correct, which they are not.

Only choice B is correct for copper IUDs.

The correct answer is choice A.The nurse should tell the client that if she misses one pill, she should take the missed pill as soon as possible and continue with the next pill at the usual time.This will ensure that she maintains a continuous hormonal exposure and does not extend the hormone-free interval beyond 7 days.She does not need to use extra contraception.

Choice B is wrong because taking two pills at once and skipping the next pill will disrupt the hormonal balance and may cause side effects such as nausea or breakthrough bleeding.Choice C is wrong because discarding the missed pill and taking the next pill at the usual time will shorten the duration of hormonal exposure and increase the risk of ovulation.Choice D is wrong because stopping taking the pills for the rest of the cycle and using a backup method of contraception will expose the client to an unnecessary hormone-free interval and may compromise her contraceptive efficacy.

COCs are combined oral contraceptives that contain synthetic estrogen and progestin hormones that prevent ovulation and thicken cervical mucus to inhibit sperm penetration.The normal range of COCs dosage is 20 to 35 micrograms of estrogen and 0.1 to 3 milligrams of progestin per pill.
