A nurse is reinforcing teaching with a client who has an intrauterine device (IUD) in place and asks how it prevents pregnancy.
Which of the following responses should the nurse make?
“It releases hormones that thicken cervical mucus and prevent ovulation.”.
“It creates a local inflammatory response that impairs implantation.”.
“It alters tubal motility and interferes with sperm transport.”.
All of the above
The Correct Answer is B
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.

Correct Answer is C
Explanation
The correct answer is choice C.“I can start the injections right after I give birth if I am not breastfeeding.” This statement indicates a need for further teaching because medroxyprogesterone injections should not be started until at leastsix weeksafter giving birth if the woman is not breastfeeding.Starting the injections earlier may increase the risk ofbleeding,blood clotsanddecreased milk production.
Choice A is correct because medroxyprogesterone injections are given every12 to 13 weeksfor contraception.
Choice B is correct because medroxyprogesterone injections may causebone lossover time, and calcium supplements may help prevent this.
Choice D is correct because medroxyprogesterone injections often reduce or stop menstrual bleeding by suppressing ovulation and thinning the lining of the uterus.
Correct Answer is D
Explanation
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.
