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.

Correct Answer: A

Rationale: The correct answer is A. Amniocentesis involves the analysis of the fetal cells present in the amniotic fluid, which is extracted from the amniotic sac surrounding the developing fetus. This fluid contains cells shed by the fetus, which can be cultured and analyzed to obtain a karyotype, providing information about the fetal sex, genetic anomalies, and biochemical abnormalities. Choices B, C, and D are incorrect because chorionic villus sampling involves obtaining a sample of the chorionic villi from the placenta, not the amniotic fluid; umbilical cord blood sampling is typically used for other purposes like assessing the baby's blood for infections or genetic disorders; and ultrasound is a diagnostic imaging technique that does not involve the analysis of fetal cells for genetic information.

Correct Answer: A

Rationale: The correct answer is the Round ligaments. The round ligaments are responsible for maintaining the uterus in an anteverted and anteflexed position. These ligaments attach from the sides of the uterus and extend through the inguinal canal to the labia majora. The other choices, Broad ligaments, Cardinal ligaments, and Pubocervical ligaments, have different functions and attachments within the pelvis. Broad ligaments are a double layer of peritoneum that encloses the uterus and supports the uterine tubes. Cardinal ligaments provide support to the cervix and upper vagina. Pubocervical ligaments support the cervix and bladder.

Correct Answer: C

Rationale: Health service delivery is the component of reproductive health that specifically focuses on ensuring the provision of quality reproductive health services at all levels of the healthcare system. While safe motherhood and adolescent health are important aspects of reproductive health, they do not directly address the quality of health services delivery. Reproductive health information, although crucial, is not the component responsible for ensuring the quality of services provided.

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.
