1. 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.

2. How many autosomes does a human primary spermatocyte have?

• A. 34
• B. 44
• C. 54
• D. 33

Correct answer: B

Rationale: A human primary spermatocyte has 44 autosomes. Autosomes are chromosomes that are not involved in determining an individual's sex. In humans, there are a total of 46 chromosomes in a somatic cell, with 22 pairs of autosomes and one pair of sex chromosomes. Therefore, the correct answer is 44 autosomes, making choice B the correct answer. Choices A, C, and D are incorrect as they do not represent the accurate number of autosomes in a human primary spermatocyte.

3. Oligomenorrhea is defined as a cycle longer than:

• A. 28 days
• B. 30 days
• C. 35 days
• D. 40 days

Correct answer: C

Rationale: Oligomenorrhea is defined as a menstrual cycle longer than 35 days. A cycle of 28 days (Choice A) is within the normal range, and not considered oligomenorrhea. Similarly, 30 days (Choice B) and 40 days (Choice D) are also within the normal range. The correct definition of oligomenorrhea specifically refers to cycles longer than 35 days, making Choice C the correct answer.

4. At what age does the first menstrual period typically occur?

• A. 9 and 15 years
• B. 2 and 10 years
• C. 1 and 5 years
• D. 18 and 20 years

Correct answer: A

Rationale: The first menstrual period, known as menarche, typically occurs between the ages of 9 and 15 years. This marks the onset of puberty in females. Choices B, C, and D are incorrect because the first menstrual period does not occur as early as 2 years old, 1 year old, or as late as 18 to 20 years old.

5. Total Fertility Rate is at 6.2 births per woman in Zambia. This implies that:

• A. Zambian women will give birth to 6.2 children on average during their childbearing years.
• B. 6.2% of the time she will be pregnant during her childbearing years.
• C. 6.2% of her deliveries will not be successful.
• D. 6.2% of women will require medical intervention to become pregnant.

Correct answer: A

Rationale: A Total Fertility Rate of 6.2 means that a woman will give birth to an average of 6.2 children during her childbearing years. The correct answer is A as it accurately reflects the concept of Total Fertility Rate. Choice B is incorrect as it misinterprets the concept by equating it to a percentage of time being pregnant. Choice C is incorrect as it does not relate to the Total Fertility Rate but rather to the success rate of deliveries. Choice D is incorrect as it introduces the idea of medical intervention, which is not directly related to the Total Fertility Rate.
