1. The placenta is developed from which part of the trophoblast?

• A. Chorionic Frondosum
• B. Anchoring Villi
• C. Chorionic Laeve
• D. Body Stalk

Correct answer: A

Rationale: The correct answer is A: Chorionic Frondosum. The placenta is developed from the chorionic frondosum part of the trophoblast. This structure gives rise to the fetal part of the placenta. Choices B, C, and D are incorrect. Anchoring Villi are projections from the chorionic plate that attach the placenta to the uterine wall. Chorionic Laeve refers to the smooth chorion that covers the fetal surface of the placenta. The Body Stalk is a structure that connects the early embryo to the trophoblastic pole of the blastocyst.

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

• A. Zygote
• B. Blastomere
• C. Morula
• D. Blastocyst

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.'

3. Which component of reproductive health ensures the provision of quality reproductive health services at all levels of the health care system?

• A. Safe motherhood
• B. Adolescent health and development
• C. Health service delivery
• D. Reproductive health information

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.

4. Which phase of the menstrual cycle is variable?

• A. Ovulatory
• B. Regenerative
• C. Secretory
• D. Menstrual

Correct answer: B

Rationale: The regenerative phase of the menstrual cycle is the phase in which the endometrium rebuilds after menstruation. This phase can vary in duration from woman to woman and cycle to cycle. Choice A, the ovulatory phase, is not variable as it typically lasts around 24 hours. Choice C, the secretory phase, is also relatively consistent in its duration. Choice D, the menstrual phase, is the shedding of the endometrial lining and usually lasts around 3-7 days.

5. At 3-4 weeks of pregnancy, the breast changes include:

• A. Darkening of the nipple.
• B. Prickling, tingling sensation.
• C. Breast becomes tender.
• D. Colostrum can be expressed.

Correct answer: C

Rationale: At 3-4 weeks of pregnancy, breast changes commonly involve tenderness due to hormonal fluctuations. Darkening of the nipple (Choice A) typically occurs later in pregnancy. Prickling, tingling sensations (Choice B) are more associated with early pregnancy due to increased blood flow to the breast area. Colostrum production (Choice D) usually begins later in pregnancy, closer to the end of the third trimester.
