1. Which one of the following is not a stage in the ovarian cycle of the menstrual cycle?

A. Recruitment of Graafian follicle
B. Selection of dominant follicle
C. Luteal phase
D. Formation of corpus luteum

Correct answer: A

Rationale: The correct answer is A. The recruitment of the Graafian follicle is indeed a stage in the ovarian cycle. During the ovarian cycle, the primary follicles are recruited to develop further, leading to the formation of the Graafian follicle. The selection of the dominant follicle, luteal phase, and formation of the corpus luteum are other essential stages in the ovarian cycle. Therefore, option A is not correct as it is a crucial phase in the process of ovulation and fertilization.

2. Which of the following is not a barrier method of birth control?

A. Vaults
B. Diaphragms
C. Sterilization
D. Cervical caps

Correct answer: C

Rationale: The correct answer is C, Sterilization. Sterilization is a permanent form of birth control that involves surgical procedures to prevent pregnancy by blocking the fallopian tubes or vas deferens. Barrier methods physically prevent sperm from reaching the egg, such as vaults, diaphragms, and cervical caps. These devices create a barrier to sperm, unlike sterilization. Therefore, choices A, B, and D are all considered barrier methods of birth control.

3. Legislation allowing nursing staff to provide contraceptives has resulted in all of the following EXCEPT:

A. More nursing staff have been trained to provide family planning services
B. Many population and family planning organizations have emerged
C. Enhanced implementation of population and family planning programs
D. Male involvement in family planning services

Correct answer: D

Rationale: The correct answer is D. Male involvement in family planning services has not significantly resulted from legislation allowing nursing staff to provide contraceptives. While legislation has led to more nursing staff being trained, the emergence of population and family planning organizations, and enhanced implementation of programs, it has not directly impacted male involvement in family planning.

4. Polymenorrhoea is defined as:

A. Menstruation that occurs at an interval less than 35 days
B. Menstruation that occurs at an interval greater than 35 days
C. Menstruation that occurs at an interval less than 21 days
D. Menstruation that occurs at an interval greater than 21 days

Correct answer: C

Rationale: Polymenorrhoea is defined as menstruation that occurs at intervals shorter than 21 days. Choice A is incorrect because it describes menstruation at intervals less than 35 days. Choice B is incorrect as it describes menstruation at intervals greater than 35 days. Choice D is incorrect as it describes menstruation at intervals greater than 21 days.

5. 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.
