A nurse is caring for a client who is considering several methods of contraception. Which of the following methods of contraception should the nurse identify as being most reliable?
An intrauterine device (IUD).
An oral contraceptive.
A male condom.
A diaphragm with spermicide.
The Correct Answer is A
Choice A rationale
An intrauterine device (IUD) is one of the most reliable methods of contraception. It is a small, T-shaped device inserted into the uterus by a healthcare provider. IUDs can be hormonal or non-hormonal (copper). Hormonal IUDs release progestin, which thickens cervical mucus to prevent sperm from reaching the egg and thins the uterine lining to prevent implantation. Copper IUDs release copper ions, which are toxic to sperm. Both types of IUDs are over 99% effective and can last for several years, making them a highly reliable form of contraception.
Choice B rationale
Oral contraceptives, commonly known as birth control pills, are also effective but require daily adherence. They contain hormones (estrogen and progestin) that prevent ovulation, thicken cervical mucus, and thin the uterine lining. However, their effectiveness can decrease with missed doses, certain medications, or gastrointestinal disturbances. With typical use, their effectiveness is around 91%, meaning 9 out of 100 women may become pregnant each year.
Choice C rationale
Male condoms are a barrier method of contraception that prevent sperm from entering the uterus. They are also effective in preventing sexually transmitted infections (STIs). However, their effectiveness can be compromised by improper use, breakage, or slippage. With typical use, male condoms are about 85% effective, meaning 15 out of 100 women may become pregnant each year.
Choice D rationale
A diaphragm with spermicide is a barrier method of contraception. The diaphragm is a shallow, dome-shaped cup inserted into the vagina to cover the cervix, and spermicide is applied to kill sperm. Its effectiveness depends on correct and consistent use. With typical use, diaphragms are about 88% effective, meaning 12 out of 100 women may become pregnant each year. Additionally, diaphragms do not protect against STIs.

Correct Answer is C
Explanation
Choice A rationale
Mastitis is an infection of the breast tissue that results in breast pain, swelling, warmth, and redness. It is more common in breastfeeding women and typically occurs when bacteria enter the breast tissue through a cracked or sore nipple. While it is a postpartum complication, it is not specifically associated with the delivery of twins.
Choice B rationale
Uterine infection, also known as endometritis, is an infection of the uterine lining. It can occur after childbirth, especially if there were complications such as prolonged labor, multiple vaginal exams, or manual removal of the placenta. However, it is not specifically associated with the delivery of twins.
Choice C rationale
Uterine atony is the most common cause of postpartum hemorrhage. It occurs when the uterus fails to contract effectively after childbirth, leading to excessive bleeding. The risk of uterine atony is higher in cases of overdistension of the uterus, such as with multiple gestations (twins), polyhydramnios, or a large baby. Therefore, a client who has delivered twins is at increased risk for uterine atony.
Choice D rationale
Retained placental fragments occur when parts of the placenta remain in the uterus after childbirth. This can lead to postpartum hemorrhage and infection. While it is a potential complication, it is not specifically associated with the delivery of twins.
Correct Answer is A
Explanation
Choice A rationale
Galactopoiesis is the process of lactation maintenance and is reliant on breast stimulation and milk removal. This stage involves the ongoing production of milk in response to the infant’s demand.
Choice B rationale
Lactogenesis II refers to the onset of copious milk secretion that occurs around 2-3 days postpartum. It is triggered by the withdrawal of progesterone following the delivery of the placenta.
Choice C rationale
Mammogenesis is the development of the mammary glands during pregnancy. It involves the growth and differentiation of the breast tissue in preparation for lactation.
Choice D rationale
Lactogenesis I refers to the initial stage of milk production that begins during pregnancy and continues through the early postpartum period. It is hormonally driven and prepares the breasts for lactation. .
