A nurse is teaching a client who is prescribed COCs about the mechanism of action of these pills.

The nurse should explain that COCs prevent pregnancy by?

The correct answer is choice B. The client has a positive pregnancy test result.

This is a contraindication for bilateral tubal ligation because the procedure is a permanent form of contraception and should not be performed on a pregnant woman.

The client should be counseled about other options for birth control or termination of pregnancy.

Choice A is wrong because a history of pelvic inflammatory disease is not a contraindication for bilateral tubal ligation.It may increase the risk of complications from the surgery, such as infection or adhesions, but it does not prevent the procedure from being performed.

Choice C is wrong because a family history of breast cancer is not a contraindication for bilateral tubal ligation.It may affect the client’s decision to undergo the procedure, as some studies have suggested that tubal ligation may reduce the risk of ovarian cancer, which is associated with breast cancer.

However, this is not a medical reason to avoid the surgery.

Choice D is wrong because a history of endometriosis is not a contraindication for bilateral tubal ligation.

It may cause pelvic pain or infertility, but it does not affect the effectiveness or safety of the procedure.In fact, some studies have shown that tubal ligation may improve the symptoms of endometriosis by reducing retrograde menstruation.

The correct answer is choice A. The nurse should assess for signs of pelvic inflammatory disease (PID), which is an infection of the female reproductive organs that can be caused by sexually transmitted bacteria.PID can cause abdominal pain during sexual intercourse, as well as other symptoms such as fever, unusual vaginal discharge, and bleeding between periods.PID can lead to serious complications such as infertility and ectopic pregnancy if left untreated.

Choice B is wrong because checking the string length of the IUD is not a priority action.The string length may change due to normal variations in the position of the uterus and cervix, and does not indicate a problem with the IUD.However, if the string is missing or longer than usual, it may suggest that the IUD has moved or expelled, and the client should see a provider.

Choice C is wrong because advising the client to use a backup contraceptive method is not a priority action.The IUD is a highly effective form of birth control that does not require additional methods unless the client wants to prevent STIs.However, if the client has an STI that causes PID, using a condom may help prevent further infection and transmission.

Choice D is wrong because scheduling an appointment for IUD removal is not a priority action.The IUD does not cause PID, but it may increase the risk of infection shortly after insertion, especially if the client has an STI.The risk of PID from IUD use is very low (less than 1%) and usually disappears after 3 weeks of placement.Removing the IUD may not cure PID and may expose the client to unwanted pregnancy.
