A nurse is providing education to a patient about implantable progestin.

Which of the following statements made by the patient indicates a need for further teaching?

All of the above.

This is because IUDs have multiple mechanisms of action that prevent fertilization and implantation of the ovum.According to the search results, some of these mechanisms are:

• IUDs immobilize sperm and interfere with their migration from the vagina to the fallopian tubes.This is because copper ions released from copper IUDs are toxic for spermatozoa and impair their motility and viability.Hormonal IUDs also thicken the cervical mucus, which blocks sperm from entering the uterus.
• IUDs speed up the transport of the ovum through the fallopian tube.This is because IUDs induce a local inflammatory reaction in the endometrium, which affects the signaling between the uterus and the ovary and alters the tubal motility.This reduces the chances of fertilization by shortening the time window for sperm-egg interaction.
• IUDs inhibit fertilization and cause lysis of the blastocyst.This is because IUDs affect the function or viability of gametes, decreasing the rate of fertilization and lowering the chances of survival of any embryo that may be formed.IUDs also interfere with implantation of the fertilized ovum by creating a hostile environment in the uterine cavity.

Choice A is wrong because it only describes one mechanism of action of IUDs, not all of them.

Choice B is wrong because it only describes another mechanism of action of IUDs, not all of them.

Choice C is wrong because it only describes yet another mechanism of action of IUDs, not all of them.

The correct answer is choice B.The client should wear scrotal support for at least 48 hours after the procedure to decrease pain and swelling, and protect the wound.

Some possible explanations for the other choices are:

• Choice A is wrong because the client should avoid sexual activity for at least 1 week, not 4 weeks, after the procedure.The client will not be sterile right away and will need to use another form of birth control until the sperm count is zero.
• Choice C is wrong because the client should apply ice packs to the scrotum for at least 2 days, not 72 hours, after the procedure.Ice helps prevent tissue damage and decrease swelling and pain.
• Choice D is wrong because the client should not take aspirin for pain relief after the procedure, as it can increase the risk of bleeding.The client can take nonsteroidal anti-inflammatory drugs (NSAIDs) such as ibuprofen or naproxen instead.
