Question 1

Which of the following is the most effective method of birth control under conditions of typical use?

Accepted Answer

Vasectomy is the most effective method of birth control under conditions of typical use because it is a permanent method that does not require any ongoing action from the user.

Question 2

By removing a section of the vas deferens, a vasectomy prevents pregnancy by

Accepted Answer

A vasectomy involves cutting or sealing the vas deferens, which are the tubes that carry sperm from the testicles to the urethra. This prevents sperm from being included in the semen that is ejaculated, thereby preventing pregnancy. The procedure does not affect spermatogenesis, ejaculation, seminal vesicle function, or testosterone secretion.

Question 3

Surgical sterilization is generally not considered to be a viable contraceptive option by most young people because it

Accepted Answer

Surgical sterilization is considered a permanent form of contraception, making it not reliably reversible, which is why most young people do not consider it a viable option.

Question 4

Two new methods to prevent pregnancy involve insertion of small plugs or metal coils into the oviducts. The resulting tissue reaction

Accepted Answer

The insertion of small plugs or metal coils into the oviducts is designed to cause a tissue reaction that permanently blocks sperm transport into the oviduct, preventing sperm from reaching and fertilizing an egg.

Question 5

Which of the following statements about intellectually disabled individuals is false?

Accepted Answer

Intellectually disabled individuals are not necessarily sexually disabled nor do they inherently lack interest in engaging in sexual activity. Their intellectual disability does not directly correlate with their sexual desires or capabilities.

Question 6

Clinical trials in China have demonstrated that administration of testosterone is an effective hormonal contraceptive for men. The testosterone most likely works by

Accepted Answer

Testosterone administration in men leads to feedback inhibition of luteinizing hormone (LH) and follicle-stimulating hormone (FSH) due to the negative feedback mechanism on the hypothalamus and pituitary gland. This reduction in LH and FSH levels leads to decreased stimulation of the testes, resulting in reduced sperm production and therefore acts as a contraceptive method.

Question 7

Organizations developing new contraceptive methods face some potential challenges, including the risk that a new method may

Accepted Answer

All of the listed options are potential challenges faced by organizations developing new contraceptive methods. A) There's a risk of harm to a developing fetus if the method fails. B) New methods can cause undesirable side effects. C) There's a possibility of inducing permanent infertility, which would be a significant concern. D) Political and religious groups may resist contraception research, affecting its development and adoption.

Question 8

Approximately _______% of abortions are performed within the first 12 weeks of pregnancy.

Accepted Answer

Approximately 90% of abortions are performed within the first 12 weeks of pregnancy. This period is considered the first trimester, during which the majority of abortions occur due to various reasons, including the lower risk associated with earlier procedures.

Question 9

Approximately 1 in 5 established pregnancies in the United States is terminated by

Accepted Answer

Elective abortion is the correct answer because it is a common procedure in the United States, with statistics showing that about 1 in 5 established pregnancies ends in elective abortion. This rate reflects the choices made by individuals or couples regarding their pregnancies for a variety of personal, health, or economic reasons. The other options, while they can affect pregnancy outcomes, do not account for as large a proportion of pregnancy terminations.

Question 10

Which of the following statements about abortion is true?

Accepted Answer

Many women who have abortions were using contraception when they became pregnant, indicating that contraceptive failure is a common reason for unintended pregnancies.

Question 11

Question 18

The anticancer drug methotrexate induces abortion by

Accepted Answer

Methotrexate works by inhibiting the metabolism of folic acid, which is necessary for the synthesis of nucleotides and thus DNA replication. This action primarily affects rapidly dividing cells, such as those found in a developing fetus, leading to its termination.

Question 19

According to one study, the rates of psychiatric visits among women who had a first abortion were higher than they were among women who had given birth for the first time. According to other studies, the most likely reason is that

Accepted Answer

The most likely reason for the higher rates of psychiatric visits among women who had a first abortion, compared to those who had given birth for the first time, is that the women who had abortions had sought psychiatric treatment in greater numbers even before the abortion. This suggests pre-existing mental health concerns rather than the abortion itself being the primary cause of increased psychiatric visits.

Question 20

Although the majority of Americans support Roe v. Wade, which permits women to have an early abortion for any reason, many people are uncomfortable with allowing abortion if

Accepted Answer

Most Americans support Roe v. Wade for significant reasons like rape, incest, severe fetal abnormalities, or threats to the woman's life, but support often decreases for reasons viewed as less critical, such as convenience.
