1. 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.

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. The follicular phase is to the __________ as the luteal phase is to the secretory phase.

• A. Postovulatory
• B. Menstrual
• C. Proliferative
• D. Ovulatory

Correct answer: C

Rationale: The correct answer is C: Proliferative. The follicular phase corresponds to the proliferative phase during the menstrual cycle, characterized by the development of ovarian follicles. The luteal phase, on the other hand, corresponds to the secretory phase when the endometrium prepares for implantation. Choices A, B, and D are incorrect because they do not accurately reflect the phases being compared in the question.

4. Mrs. Banda is a patient at the ward with complaints of light menstrual periods, which occur at intervals greater than 35 days. Your diagnosis will be:

• A. Oligomenorrhea
• B. Menorrhagia
• C. Metrorrhagia
• D. Polymenorrhea

Correct answer: A

Rationale: The correct diagnosis for Mrs. Banda's condition is Oligomenorrhea. Oligomenorrhea is characterized by light menstrual periods occurring at intervals longer than 35 days. Choice B, Menorrhagia, refers to abnormally heavy menstrual bleeding. Choice C, Metrorrhagia, is bleeding at irregular intervals, and Choice D, Polymenorrhea, involves menstrual cycles occurring at intervals shorter than 21 days.

5. Why is abortion important?

• A. It is easily conducted
• B. It can easily be diagnosed
• C. It causes serious complications such as infections and maternal death
• D. All of the above

Correct answer: C

Rationale: Abortion is important due to the serious complications it can cause, such as infections and maternal death. Choices A and B are incorrect because ease of conducting or diagnosing abortion procedures does not inherently make abortion important. Choice D is incorrect because not all the options listed are reasons why abortion is important; only choice C highlights the critical aspect of potential complications.
