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 A
Explanation
The correct answer is choice A.A history of toxic shock syndrome (TSS) is a contraindication for the use of a diaphragm.
TSS is a rare but serious condition caused by a bacterial infection that can occur when using a diaphragm for too long or not cleaning it properly.
Choice B is wrong because a history of uterine fibroids is not a contraindication for the use of a diaphragm.
Uterine fibroids are benign tumors that grow in the uterus and usually do not affect the cervix or the fit of the diaphragm.
Choice C is wrong because a history of irregular menstrual periods is not a contraindication for the use of a diaphragm.
Irregular periods may be caused by various factors such as stress, hormonal imbalance, or medical conditions, but they do not affect the effectiveness or safety of the diaphragm.
Choice D is wrong because a history of breast cancer is not a contraindication for the use of a diaphragm.
Breast cancer is not related to the use of barrier methods of contraception such as the diaphragm.
However, some hormonal methods of contraception may increase the risk of breast cancer or be contraindicated for women who have or had breast cancer.
Correct Answer is A
Explanation
The correct answer is choice A.COCs prevent pregnancy byinhibiting the production of follicle-stimulating hormone (FSH) and luteinizing hormone (LH), which are responsible for ovulation.
By suppressing ovulation, COCs prevent the release of a mature egg that can be fertilized by sperm.
Choice B is wrong because COCs do not increase the production of prostaglandins that cause uterine contractions.
Prostaglandins are involved in inflammation and pain, and are not directly related to contraception.
Choice C is wrong because COCs do not decrease the permeability of the fallopian tubes to sperm and egg.
The fallopian tubes are the site of fertilization, and COCs do not affect their function.
Choice D is partially correct but not the best answer.COCs do suppress ovulation, but they also have other mechanisms of action, such asthickening cervical mucusandaltering the uterine lining.
These effects make it harder for sperm to reach the egg and for a fertilized egg to implant in the uterus.
Therefore, choice D does not capture the full mechanism of action of COCs.
