Reproductive System Exam Quizlet

1. At what point is a fetus considered viable?

A. 26 weeks
B. 28 weeks
C. 37 weeks
D. 12 weeks

Correct answer: C

Rationale: A fetus is considered viable after 37 weeks of gestation. At this stage, the fetus has a higher chance of surviving outside the womb with medical support. Choice A (26 weeks), Choice B (28 weeks), and Choice D (12 weeks) are incorrect because a fetus is not typically considered viable at those earlier gestational ages.

2. At 8-12 weeks of pregnancy, the breast changes include:

A. Prickling, tingling sensation.
B. Nipples become prominent and mobile.
C. Darkening of the nipple.
D. Breast start producing milk

Correct answer: D

Rationale: At 8-12 weeks of pregnancy, the breast changes typically include the onset of colostrum production, not just tenderness. Colostrum is the first milk produced by the mammary glands during pregnancy. While some women may experience prickling or tingling sensations, prominent and mobile nipples, and darkening of the nipple, the key change during this time period is the production of colostrum. This substance is rich in antibodies and important for the newborn's initial nutrition. Therefore, the correct answer is not listed among the choices provided.

3. The programs aimed at achieving total reproductive health as a social goal at the national level are called:

A. Family organization
B. Family planning
C. Reproductive care
D. Reproductive health

Correct answer: D

Rationale: The correct answer is D, 'Reproductive health.' Reproductive health programs focus on ensuring overall well-being in relation to reproduction, including access to reproductive services, education, and healthcare. Choice A, 'Family organization,' does not specifically address health aspects related to reproduction. Choice B, 'Family planning,' is more focused on birth control and family size rather than the broader aspects of reproductive health. Choice C, 'Reproductive care,' is limited to the aspect of medical care and does not encompass the comprehensive approach of reproductive health programs.

4. Which of the following is a function of the placenta?

A. The placenta secretes insulin.
B. The placenta facilitates the exchange of gases and nutrients between mother and fetus.
C. The placenta provides immunological protection to the fetus.
D. The placenta stores fat-soluble vitamins for the fetus.

Correct answer: B

Rationale: The correct answer is B. The placenta serves as a crucial organ during pregnancy, facilitating the exchange of gases (oxygen and carbon dioxide) and nutrients (such as glucose and amino acids) between the mother and the developing fetus. This exchange is vital for the fetus's growth and development. Choices A, C, and D are incorrect. The placenta does not secrete insulin; insulin is produced by the pancreas. While the placenta provides some immune support to the fetus, its main role is not immunological protection. Additionally, storing fat-soluble vitamins is not a primary function of the placenta.

5. What is one of the major issues affecting adolescents in terms of sexual and reproductive health?

A. Limited access to contraceptives and family planning
B. Equal representation in decision-making
C. Decreased need for sexual education
D. Equal opportunities for career growth

Correct answer: A

Rationale: Limited access to contraceptives and family planning is indeed a major issue affecting adolescents in terms of sexual and reproductive health. This lack of access can lead to unintended pregnancies, sexually transmitted infections, and limited reproductive choices. Choice B, equal representation in decision-making, although important, is not directly related to sexual and reproductive health issues faced by adolescents. Choice C, decreased need for sexual education, is incorrect as proper sexual education is crucial in promoting healthy behaviors and preventing risks. Choice D, equal opportunities for career growth, is also unrelated to the specific issues surrounding sexual and reproductive health in adolescents.
