The testosterone secretion is controlled by:
- A. the FSH;
- B. the LH;
- C. the corticoadrenal;
- D. the negative feedback of posterior pituitary;
Correct Answer: B
Rationale: Step 1: LH (luteinizing hormone) is produced by the pituitary gland and plays a key role in stimulating the Leydig cells in the testes to produce testosterone.
Step 2: Testosterone secretion is directly controlled by the LH through this stimulation.
Step 3: FSH (follicle-stimulating hormone) is involved in sperm production, not testosterone secretion.
Step 4: Corticoadrenal hormones are related to stress response, not testosterone regulation.
Step 5: Negative feedback from the posterior pituitary does not directly control testosterone secretion.
Therefore, the correct answer is B (the LH) as it directly influences testosterone production.

Sperm maturation occurs in the
- A. seminiferous tubules
- B. epididymis
- C. vas deferens
- D. urethra
Correct Answer: B
Rationale: The correct answer is B: epididymis. Sperm maturation occurs in the epididymis, a coiled tube located on the posterior surface of the testes. Here, sperm undergo the process of capacitation, gaining the ability to fertilize an egg. The seminiferous tubules (choice A) are responsible for sperm production, not maturation. The vas deferens (choice C) is a duct that carries mature sperm from the epididymis to the urethra, and the urethra (choice D) is a passage for both urine and sperm but not the site of sperm maturation.
Benign tumors originating in the myometrium are
- A. Fibroids
- B. Rhabdomyoma
- C. Leiomyoma
- D. Both a & c
Correct Answer: D
Rationale: The correct answer is D (Both a & c) because benign tumors originating in the myometrium are typically either fibroids (choice A) or leiomyomas (choice C), which are essentially the same thing. Fibroids and leiomyomas are both non-cancerous growths arising from smooth muscle cells in the myometrium. Rhabdomyoma (choice B) is a benign tumor arising from striated muscle cells, not smooth muscle cells like fibroids and leiomyomas. So, choices A, B, and C are incorrect because only fibroids and leiomyomas specifically originate in the myometrium.
A patient asks when she can stop having Pap (Papanicolaou) tests. What is the nurse’s most appropriate response?
- A. Until you are no longer sexually active.
- B. Through age 65.
- C. Until you begin menopause.
- D. Through the end of menopause.
Correct Answer: B
Rationale: The correct answer is B: Through age 65. This is because current guidelines recommend that women continue to have Pap tests every 3-5 years until age 65, assuming previous tests have been normal. This age cutoff is based on the decreasing risk of cervical cancer with age and the low likelihood of developing new HPV infections after this age. Choices A, C, and D are incorrect because they do not align with the most up-to-date screening recommendations and may lead to unnecessary testing or missed opportunities for appropriate screening.
While performing a breast examination on a 22-year-old client, you obtain all of these data. Which information is of most concern?
- A. Both breasts have many nodules in the upper, outer quadrants.
- B. Client complains of bilateral breast tenderness with palpation.
- C. The breast on the right side is slightly larger than the left breast.
- D. An irregularly shaped, nontender lump is palpable in the left breast.
Correct Answer: D
Rationale: An irregularly shaped, nontender lump may indicate malignancy, requiring further investigation.
The shedding of the lining of the uterus along with some blood once a month. Also called a monthly period:
- A. Gestation
- B. Conception
- C. Menstruation
- D. ovulation
Correct Answer: C
Rationale: The correct answer is C: Menstruation. Menstruation is the process where the lining of the uterus sheds along with some blood once a month. This occurs in females who are not pregnant. Gestation (A) refers to the period of development of a baby in the womb. Conception (B) is the fertilization of an egg by sperm. Ovulation (D) is the release of an egg from the ovary. Menstruation best describes the shedding of the uterine lining and blood during a monthly period.
