The spermatozoon:
- A. is the primordial male cell;
- B. is a microscopic cell;
- C. forms within the interstitial cells;
- D. is a diploid cell;
Correct Answer: A
Rationale: The correct answer is A because the spermatozoon is indeed the primordial male cell, the precursor to all other male reproductive cells. Choice B is incorrect because the term "microscopic cell" is too broad and does not specifically define the spermatozoon. Choice C is incorrect because spermatozoa are actually formed within the seminiferous tubules of the testes, not the interstitial cells. Choice D is incorrect because spermatozoa are haploid cells, not diploid. Therefore, only choice A accurately describes the nature and origin of the spermatozoon.

The development strategy where the young develop within their mother's uterus and obtain nourishment from the mother via placenta is best described as
- A. Oviparity.
- B. Viviparity.
- C. Semelparity.
- D. Ovoviviparity.
Correct Answer: B
Rationale: The correct answer is B: Viviparity. Viviparity refers to the development strategy where young develop within the mother's uterus and receive nourishment through the placenta. This is the best description for the scenario provided.
A: Oviparity involves laying eggs externally.
C: Semelparity is a reproductive strategy where an organism reproduces only once in its lifetime.
D: Ovoviviparity is a combination of oviparity and viviparity, where eggs are retained within the mother's body until they hatch.
Each menstrual cycle is considered as a period of ________
- A. 28 days
- B. 30 days
- C. 42 days
- D. 14 days
Correct Answer: A
Rationale: The correct answer is A: 28 days because the average menstrual cycle length is typically around 28 days, although it can vary. The menstrual cycle consists of different phases such as menstruation, follicular phase, ovulation, and luteal phase, which collectively last around 28 days on average. Choice B (30 days), C (42 days), and D (14 days) are incorrect because they do not represent the typical duration of a menstrual cycle. It's important to note that individual variations in cycle length are common, but 28 days is considered a standard reference point.
Which of the following is responsible for secondary sex characteristics in females?
- A. Estrogens
- B. Progesterone
- C. Follicl
- D. stimulating hormone (FSH)
Correct Answer: A
Rationale: Estrogens are responsible for secondary sex characteristics in females as they promote breast development, regulate the menstrual cycle, and contribute to the distribution of body fat. Progesterone mainly prepares the uterus for pregnancy. Follicle-stimulating hormone (FSH) plays a role in the development of ovarian follicles and the maturation of eggs but does not directly influence female secondary sex characteristics.
The male reproductive system is made up of the following structures, EXCEPT:
- A. prostate;
- B. testicle;
- C. spermatic ducts;
- D. vestibular bulbs;
Correct Answer: D
Rationale: The correct answer is D: vestibular bulbs. The male reproductive system consists of the prostate, testicles, and spermatic ducts, all essential for the production, storage, and transportation of sperm. Vestibular bulbs are actually part of the female reproductive system, involved in sexual arousal, and not found in the male reproductive system. Therefore, it is the only structure listed that is not a part of the male reproductive system.
A client with the herpes simplex virus type 2 (HSV-2) undergoes a viral shedding. Which of the following statements is true when caring for a client with HSV-2?
- A. An outbreak of the HSV-2 infection is often self-limiting and hence a treatment may be unnecessary.
- B. Clients don't seek treatment because of embarrassment.
- C. Healthcare providers and laboratories are not required by law to report.
- D. Reporting is up to the client, not the provider.
Correct Answer: A
Rationale: HSV-2 outbreaks are often self-limiting, though antiviral medications can help manage symptoms.
