1. 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.

2. What is the content of the acrosome?

• A. Lipids
• B. Hormones
• C. Digestive enzymes
• D. None of the above

Correct answer: C

Rationale: The correct answer is C: Digestive enzymes. The acrosome is a structure found in sperm cells that contains enzymes used to penetrate the egg during fertilization. Choice A (Lipids) and Choice B (Hormones) are incorrect as the primary content of the acrosome is digestive enzymes, not lipids or hormones. Choice D (None of the above) is incorrect as the acrosome does contain a specific substance, which are digestive enzymes.

3. Abortion is defined as:

• A. Bleeding per vaginum in early pregnancy
• B. Willingness to terminate pregnancy
• C. Expulsion of products of conception after the 28th week of gestation
• D. Expulsion of products of conception before the 28th week of gestation

Correct answer: D

Rationale: Abortion is defined as the expulsion of products of conception before the 28th week of gestation. Choice A is incorrect as it describes bleeding in early pregnancy, not the definition of abortion. Choice B is incorrect as it refers to the willingness to terminate a pregnancy rather than the actual act of expulsion. Choice C is incorrect as it defines abortion as the expulsion of products of conception after the 28th week of gestation, which is considered a stillbirth.

4. What is one of the roles of the oxytocin hormone?

• A. Stimulates milk ejection.
• B. Stimulates the production of milk.
• C. Stimulates the development of lactoferrin.
• D. Stimulates the secretion of relaxin.

Correct answer: A

Rationale: The correct answer is A: 'Stimulates milk ejection.' Oxytocin is responsible for contracting the muscles around the milk ducts, pushing milk into the nipples for breastfeeding. This process is known as milk ejection or let-down. The other choices are incorrect because oxytocin's primary function is to facilitate milk ejection rather than directly stimulating the production of milk, the development of lactoferrin, or the secretion of relaxin.

5. Which contraceptive option suppresses sperm motility and inhibits the implantation of the blastocyst?

• A. Copper-T
• B. Diaphragm
• C. Contraceptive pills
• D. Condom

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.
