Reproductive Health Exam

1. A solid ball of 12-16 cells having undergone mitotic division after fertilization is:

Correct answer: C

Rationale: A morula is a stage in embryonic development where a solid ball of 12-16 cells is formed after several rounds of mitotic division following fertilization. The zygote is the initial cell formed by the fusion of sperm and egg. Blastomere refers to individual cells in a developing embryo. A blastocyst is a later stage where a fluid-filled cavity forms within the embryo. Therefore, the correct answer is 'Morula.'

2. What is one role of the hormone estrogen?

Correct answer: A

Rationale: The correct answer is A: Estrogen stimulates the development of the milk-producing tissue in the breast. This hormone is essential in preparing the breast for milk production. Choice B is incorrect because lactoferrin production is not a primary role of estrogen. Choice C is incorrect as estrogen primarily influences the development of the breast tissue rather than specifically the nipple and duct system. Choice D is incorrect because relaxin secretion is not a function typically associated with estrogen.

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

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. What is the inner lining of the non-pregnant uterus called?

Correct answer: C

Rationale: The correct answer is C, Endometrium. The endometrium is the inner lining of the non-pregnant uterus that undergoes cyclic changes in response to hormonal fluctuations during the menstrual cycle. Choice A, Decidua, is the specialized membrane formed during pregnancy. Choice B, Myometrium, refers to the middle layer of the uterine wall composed of smooth muscle. Choice D, Sponge layer, is not a term used to describe the inner lining of the uterus.

5. Which of the following is not a complication of menopause?

Correct answer: C

Rationale: Congestive heart failure is not typically associated with menopause. Menopause is linked to an increased risk of fractures due to bone density loss, a higher risk of Alzheimer's disease due to hormonal changes affecting the brain, and painful intercourse due to vaginal dryness and decreased lubrication. While cardiovascular health can be affected by menopause, congestive heart failure is not a direct complication of menopause.
