1. Approximately how many primordial follicles are present in the cortex of the ovary at birth?

A. 250,000
B. 200,000
C. 150,000
D. 100,000

Correct answer: A

Rationale: The correct answer is A: 250,000. At birth, there are approximately 250,000 primordial follicles in the cortex of each ovary. These primordial follicles represent the reserve of oocytes that a female will have throughout her reproductive life. Choice B, 200,000, is incorrect as the number is higher. Choices C and D, 150,000 and 100,000 respectively, are also incorrect as they underestimate the actual number of primordial follicles present at birth.

2. According to the Medical Termination of Pregnancy (MTP) Act, 1971, how many weeks of pregnancy is Medical Termination of Pregnancy considered safe up to?

A. 8 Weeks
B. 12 Weeks
C. 18 Weeks
D. 6 Weeks

Correct answer: B

Rationale: According to the Medical Termination of Pregnancy (MTP) Act, 1971, Medical Termination of Pregnancy is considered safe up to 12 weeks of pregnancy. This timeframe is crucial to ensure the safety and well-being of the individual undergoing the procedure. Choices A, C, and D are incorrect because they do not align with the legal provisions outlined in the MTP Act, 1971.

3. At 6-8 weeks of pregnancy, the breast changes include:

A. Colostrum can be expressed.
B. Breasts become tender.
C. Montgomery's tubercles are prominent.
D. Nipples become prominent and mobile.

Correct answer: C

Rationale: At 6-8 weeks of pregnancy, one of the changes in the breast includes the prominence of Montgomery's tubercles. These sebaceous glands around the nipple become more noticeable at this stage. Colostrum production usually occurs later in pregnancy, typically closer to the third trimester. While breast tenderness is a common symptom of early pregnancy, it is not specific to the 6-8 week timeframe. Nipples becoming more prominent and mobile may happen later in pregnancy as the body prepares for breastfeeding, but it is not a typical change seen specifically at 6-8 weeks.

4. What is the role of the corpus luteum during the menstrual cycle?

A. The corpus luteum produces estrogen to maintain the endometrium.
B. The corpus luteum produces progesterone to maintain the endometrium.
C. The corpus luteum produces testosterone to inhibit ovulation.
D. The corpus luteum has no significant role during the menstrual cycle.

Correct answer: B

Rationale: The correct answer is B: The corpus luteum produces progesterone to maintain the endometrium during the menstrual cycle. This hormone helps prepare the uterine lining for implantation in case fertilization occurs. Choice A is incorrect because estrogen is mainly produced by the developing follicles in the ovaries. Choice C is incorrect as testosterone is produced in smaller amounts by the ovaries and adrenal glands but does not play a significant role in maintaining the endometrium. Choice D is incorrect as the corpus luteum plays a crucial role in producing progesterone to support the endometrium.

5. In order to provide services effectively and in the best interests of the whole family:

A. The wife's relatives need to be contacted
B. It's important to seek the services of a traditional healer
C. Health providers need to be aware of the roles and decision-making process within the family
D. Health providers need to conduct door-to-door sensitization on health matters

Correct answer: C

Rationale: The correct answer is C: 'Health providers need to be aware of the roles and decision-making process within the family.' To provide services effectively, health providers must understand the dynamics within a family, including who makes decisions and how roles are distributed. This knowledge helps them tailor their services to meet the needs and preferences of the whole family. Choices A and B are incorrect because contacting the wife's relatives or seeking the services of a traditional healer may not necessarily align with providing effective services based on family dynamics. Choice D is also incorrect as door-to-door sensitization may not directly address the internal dynamics of a family.
