What is the cause of menopause?
- A. Reduced levels of gonadotropic hormones secreted from the anterior pituitary gland
- B. Reduced responsiveness of the follicles to the stimulatory effects of gonadotropic hormones
- C. Reduced rate of secretion of progesterone from the corpus luteum
- D. Reduced numbers of follicles available in the ovary for stimulation by gonadotropic hormones
Correct Answer: D
Rationale: The correct answer is D because menopause occurs when the ovaries run out of follicles, which are needed for ovulation and hormone production. This leads to reduced estrogen levels and cessation of menstrual cycles. Choices A and B focus on hormone levels and follicle responsiveness, not the actual follicle count. Choice C is incorrect as progesterone is mainly produced by the corpus luteum after ovulation, not the primary cause of menopause.

A major function of FSH is to
- A. stimulate the development of the gonads during early development.
- B. stimulate spermatogenesis in males and oocytes maturation in females.
- C. increase the secretion of testosterone by the testes.
- D. regulate the secretion of the bulbourethral gland
Correct Answer: B
Rationale: The correct answer is B because FSH, or Follicle-Stimulating Hormone, stimulates spermatogenesis in males and oocyte maturation in females. In males, FSH acts on the Sertoli cells in the testes to promote the development of sperm cells. In females, FSH stimulates the growth and maturation of ovarian follicles, leading to the release of mature eggs.
Choice A is incorrect because FSH is not primarily responsible for the development of gonads during early development. Choice C is incorrect because FSH does not directly increase the secretion of testosterone by the testes; that is the role of LH (Luteinizing Hormone). Choice D is incorrect because FSH does not regulate the secretion of the bulbourethral gland; that is controlled by other hormones.
During a physical examination of the male reproductive system, how does the nurse assist the examiner to gather clues about the density of scrotal tissue?
- A. Through a digital rectal examination
- B. By externally inspecting the size of the scrotum
- C. Through transillumination
- D. Through a scrotal radiography
Correct Answer: C
Rationale: Transillumination helps assess the density and presence of fluid in the scrotum.
Choose the correct statements:
- A. every month, a secondary follicle becomes a mature follicle;
- B. the ovary displays a cortical area in which the following are found: lax connective tissue, vessels and nerves.
- C. monthly, beginning with puberty, a mature follicle transforms into a tertiary follicle;
- D. during the female sex life, approximately 400 ovarian follicles become mature;
Correct Answer: B
Rationale: The correct answer is B because the ovary does indeed display a cortical area with lax connective tissue, vessels, and nerves. This area is known as the ovarian cortex. This choice accurately describes the anatomical features present in the ovary.
Choice A is incorrect because not every month does a secondary follicle become a mature follicle. It is a gradual process that occurs over several cycles.
Choice C is incorrect because a mature follicle does not transform into a tertiary follicle monthly starting from puberty. Instead, a mature follicle releases an egg during ovulation.
Choice D is incorrect because the average female has around 400,000 follicles at birth, and only about 400 will become mature and be released during her reproductive years.
Her Hemovac has drained 60 ml postoperative day 1, 55 ml postoperative day 2, and 40 ml thus far today. She asks you when will the drain be removed. Which would be the most appropriate response?
- A. It will be removed the day you go home.'
- B. Usually the doctor waits until the drainage subsides or stops altogether.'
- C. I'm surprised the doctor didn't take it out by now.'
- D. If you ask your doctor maybe he'll take it out next time he comes in.'
Correct Answer: B
Rationale: The drain is usually removed once the drainage subsides or stops, indicating proper healing.
At the level of the testicle, the efferent ducts:
- A. continue the rete testis;
- B. open in the epididymal duct;
- C. open in the deferent duct;
- D. are 30;
Correct Answer: A
Rationale: Rationale for Correct Answer A: The efferent ducts continue the rete testis. This is true because the efferent ducts are a series of small ducts that connect the rete testis to the epididymis. The rete testis is a network of tubules located at the back of the testicle where spermatozoa from the seminiferous tubules are collected. Therefore, the efferent ducts serve to transport spermatozoa from the rete testis to the epididymis for further maturation.
Summary of Incorrect Choices:
B: Opening in the epididymal duct is incorrect because the efferent ducts lead into the epididymis, not the epididymal duct itself.
C: Opening in the deferent duct is incorrect because the efferent ducts do not lead directly into the deferent duct, but rather connect the rete testis to the epididym
