Men who take large doses of testosterone-like androgenic steroids for long periods are sterile in the reproductive sense of the word. What is the explanation for this finding?

  • A. High levels of androgens bind to testosterone receptors in the Sertoli cells, resulting in overstimulation of inhibin formation
  • B. Overstimulation of sperm cell production results in the formation of defective sperm cells
  • C. High levels of androgen compounds inhibit the secretion of gonadotropin-releasing hormone by the hypothalamus, resulting in the inhibition of luteinizing hormone and follicle-stimulating hormone release by the anterior pituitary
  • D. High levels of androgen compounds produce hypertrophic dysfunction of the prostate gland
Correct Answer: C

Rationale: The correct answer is C because high levels of androgen compounds inhibit the secretion of gonadotropin-releasing hormone (GnRH) by the hypothalamus. GnRH is responsible for stimulating the release of luteinizing hormone (LH) and follicle-stimulating hormone (FSH) by the anterior pituitary gland. LH and FSH are crucial for proper testicular function, including sperm production. When the secretion of GnRH is inhibited by high levels of androgens, it leads to a decrease in LH and FSH levels, ultimately disrupting the normal feedback loop of the hypothalamic-pituitary-gonadal axis. This disruption results in impaired sperm production and fertility.

Choice A is incorrect because overstimulation of inhibin formation does not directly lead to sterility. Choice B is incorrect because overstimulation of sperm cell production would not result in the formation of defective sperm cells leading to sterility. Choice D is incorrect because hypert

Which of the following does not occur during puberty in a female?

  • A. Increased fat deposits beneath the skin
  • B. Onset of menopause
  • C. Widening and lightening of the pelvis
  • D. Development of the breasts
Correct Answer: B

Rationale: The correct answer is B: Onset of menopause. Puberty is the period of sexual maturation and development, typically occurring in adolescence. Menopause, on the other hand, is the cessation of menstruation and fertility, usually happening in women in their late 40s or early 50s. During puberty in females, there is an increase in fat deposits beneath the skin, widening and lightening of the pelvis to prepare for childbirth, and development of the breasts as part of secondary sexual characteristics. Menopause does not occur during puberty; it is a separate phase in a woman's reproductive life cycle. Therefore, B is the correct answer.

Mrs. Kwame is scheduled for a hysterectomy for stage III cancer of the cervix. What information will help her request appropriate p.r.n. pain medication?

  • A. Understanding prescribed drug action
  • B. Support and reassurance from the nurse
  • C. The nurse's beliefs and preferences regarding use of narcotics
  • D. Prescribed medication should be administered freely during the first 24 hours postoperatively
Correct Answer: A

Rationale: Understanding how prescribed drugs work helps patients manage pain effectively.

Which structure will actually become the fetus?

  • A. morula
  • B. blastocyst
  • C. inner cell mass
  • D. zygote
Correct Answer: C

Rationale: The correct answer is C: inner cell mass. After fertilization, the zygote undergoes several cell divisions to form a hollow ball of cells called a blastocyst. Within the blastocyst, the inner cell mass contains cells that will develop into the fetus. The morula is an earlier stage consisting of a solid ball of cells. The zygote is the initial cell formed from the fusion of egg and sperm, but it does not directly become the fetus. Therefore, the inner cell mass is the structure that will actually develop into the fetus, making it the correct answer.

Within which structure in the human body does specialization of parts of the developing baby take place?

  • A. ovary
  • B. uterus
  • C. testis
  • D. pancreas
Correct Answer: B

Rationale: The correct answer is B: uterus. Specialization of parts of the developing baby takes place in the uterus during pregnancy. The uterus is where the fertilized egg implants and the embryo develops into a specialized structure known as a fetus. The other choices (A: ovary, C: testis, D: pancreas) do not play a direct role in the development of the baby during pregnancy. The ovary is involved in producing eggs, the testis produces sperm, and the pancreas is responsible for producing digestive enzymes and hormones, but they are not directly involved in the specialization of parts of the developing baby.

After having a modified radical mastectomy, a client is transferred to the post-anesthesia care unit (PACU). All of these actions are included in the routine post-operative care for clients who have had this procedure. Which is best to delegate to an experienced LPN?

  • A. Monitor client's dressing for any signs of bleeding.
  • B. Document the initial assessment on client's chart.
  • C. Call client's status report to the charge nurse on the surgical unit.
  • D. Teach client about the importance of using pain medication as needed.
Correct Answer: A

Rationale: Monitoring the dressing for signs of bleeding is within the scope of practice for an LPN.
