A nurse is caring for a client who has a history of breast cancer and cardiovascular disease and is seeking advice on contraception.
Which of the following contraceptive methods should the nurse recommend as the safest option for this client?
Injectable progestins
Contraceptive vaginal ring
Copper intrauterine device
Combined oral contraceptives
The Correct Answer is C
The correct answer is choice C. Copper intrauterine device. This is because copper intrauterine devices do not contain hormones and are therefore safe for women with a history of breast cancer and cardiovascular disease.
Some possible explanations for the other choices are:
- Choice A. Injectable progestins. This is wrong because injectable progestins may increase the risk of breast cancer in women with the BRCA1 gene and may also worsen hypertension and dyslipidemia.
- Choice B. Contraceptive vaginal ring. This is wrong because contraceptive vaginal rings contain estrogen and progestin, which may increase the risk of thromboembolic events, stroke, and myocardial infarction in women with cardiovascular disease.
- Choice D. Combined oral contraceptives. This is wrong because combined oral contraceptives also contain estrogen and progestin, which have the same risks as contraceptive vaginal rings for women with cardiovascular disease. Additionally, combined oral contraceptives may interact with some medications used to treat chronic conditions and reduce their effectiveness.

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.
Correct Answer is B
Explanation
The correct answer is choice B. The client should start taking oral contraceptives (OCs) on day one of their menstrual cycle, which is the first day of their period.This way, they will be protected from pregnancy right away and do not need to use a back-up contraceptive method.
Choice A is wrong because starting OCs on Sunday after the period begins may leave a gap of several days when the client is not protected from pregnancy.They would need to use a back-up method for the first seven days of taking OCs.
Choice C is wrong because starting OCs on day five of the menstrual cycle may also leave a gap of unprotected days.The client would need to use a back-up method for the first seven days of taking OCs.
Choice D is wrong because starting OCs on day fourteen of the menstrual cycle is too late and may not prevent ovulation.The client would need to use a back-up method for the first seven days of taking OCs.
