Correct Answer: D

Rationale: Contraceptive abstinence refers to avoiding penis-in-vagina intercourse to prevent pregnancy. It is a method of birth control where sexual partners choose not to engage in sexual intercourse during fertile periods to avoid the risk of pregnancy. This method relies on refraining from penetrative sex or any ejaculatory contact between the penis and vagina. It is a natural form of birth control and does not involve the use of contraceptives or devices.

Correct Answer: A

Rationale: One advantage of the internal condom is that it can be used by individuals who have a latex allergy. Traditional external condoms are typically made from latex, which can cause allergic reactions in some people. Internal condoms, also known as female condoms, are usually made from nitrile or polyurethane, providing a latex-free alternative for those with sensitivities or allergies to latex. This makes the internal condom a viable option for a wider range of individuals, ensuring that they can still practice safe sex without risking allergic reactions.

Correct Answer: C

Rationale: Instructions for the use of nonoxynol-9 spermicide should include removing any excess spermicide from the vagina within 6 hours after intercourse. This step is important to reduce the risk of vaginal irritation, which can occur if the spermicide is left in the vagina for an extended period of time. It is crucial to follow this guidance to ensure the user's comfort and overall well-being.

Correct Answer: A

Rationale: Estrogen in combined oral contraceptive (COC) pills works primarily by inhibiting ovulation through the suppression of the luteinizing hormone (LH) surge. By maintaining consistent levels of estrogen in the body, COC pills prevent the release of eggs from the ovary. This prevents fertilization from occurring, which is one of the main mechanisms of action of COC pills to provide contraception. While estrogen also has other effects such as stabilizing the endometrium to reduce unscheduled bleeding, its main role in COC pills is to inhibit ovulation and prevent pregnancy through hormonal regulation.
