Discuss the anatomical/physiological changes in pregnancy related to the breasts.

Correct Answer: A

Rationale: During pregnancy, the breasts undergo significant anatomical and physiological changes. These changes include increased breast tenderness, an increase in circulatory supply to the breasts, resulting in breast enlargement, and the secretion of colostrum. Choice B is incorrect as breast tenderness actually increases during pregnancy. Choice C is incorrect as the circulatory supply to the breasts increases rather than reduces. Choice D is incorrect as breasts do undergo notable changes during pregnancy.

Correct Answer: C

Rationale: There are two arteries in an umbilical cord. The umbilical cord contains two arteries and one vein. Artery carries blood away from the fetus, while the vein returns blood to the fetus. Therefore, choices A, B, and D are incorrect as they do not represent the correct number of arteries in an umbilical cord.

Correct Answer: A

Rationale: The correct answer is A: 'Irreversible.' An ideal contraceptive should not be irreversible because it should allow individuals to have the option to discontinue its use if desired. Choices B, C, and D are characteristics of an ideal contraceptive. Contraceptives should be easily available to ensure widespread accessibility, user-friendly to promote proper and consistent use, and effective with minimal side effects to maximize safety and tolerability.

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.

Correct Answer: A

Rationale: The correct answer is A, Copper-T. Copper-T is an intrauterine device that releases copper ions, which suppress sperm motility and inhibit the implantation of the blastocyst. This method mainly works by preventing fertilization and, if fertilization occurs, by making the endometrium less receptive to implantation. Choices B, C, and D are incorrect. The diaphragm is a barrier method that prevents sperm from reaching the cervix; contraceptive pills mainly work by suppressing ovulation and altering cervical mucus to prevent sperm from reaching the egg; condoms are barrier methods that prevent sperm from entering the vagina.
