The Luteinizing hormone acts on the interstitial cells to produce
- A. Androgen
- B. Estrogen
- C. Progestin
- D. Testosterone
Correct Answer: D
Rationale: The correct answer is D, Testosterone. The luteinizing hormone acts on the interstitial cells in the testes to stimulate the production of testosterone. Testosterone is a male sex hormone responsible for the development of male reproductive tissues and characteristics. Androgen (choice A) is a broad term that includes testosterone, so it is not specific enough. Estrogen (choice B) and Progestin (choice C) are female sex hormones and are not produced by the interstitial cells in response to luteinizing hormone. Hence, the correct answer is D.

The cell labeled H in the figure secretes which of the following hormones?
- A. renin
- B. progesterone
- C. aldosterone
- D. estrogen
Correct Answer: C
Rationale: The correct answer is C: aldosterone. The cell labeled H is located in the adrenal gland zona glomerulosa, which secretes aldosterone. Aldosterone regulates electrolyte balance by increasing reabsorption of sodium and water in the kidneys. Renin (A) is secreted by the juxtaglomerular cells, progesterone (B) is produced by the ovaries and adrenal glands, and estrogen (D) is produced by the ovaries and placenta. None of these hormones are secreted by the cell labeled H.
Vener/o refers to:
- A. Vagina
- B. Vulva
- C. Sexual intercourse
- D. Hymen
Correct Answer: B
Rationale: The correct answer is B: Vulva. The term "vener/o" specifically refers to the external female genitalia, which includes the labia, clitoris, vaginal opening, and other structures collectively known as the vulva. The term does not refer to the vagina (A), which is the internal canal leading to the cervix. It also does not refer to sexual intercourse (C), which is the act of engaging in sexual activity. Lastly, it is not related to the hymen (D), which is a thin membrane partially covering the vaginal opening. Therefore, based on the definition and context of the term "vener/o," the correct answer is B: Vulva.
The spermatic cord houses the
- A. testosterone production ________.
- B. ovum fertilization
- C. urethra
- D. sperm production
Correct Answer: D
Rationale: The correct answer is D: sperm production. The spermatic cord houses the structures that support and transport sperm, including the vas deferens, blood vessels, nerves, and lymphatics. It does not produce testosterone (A), facilitate ovum fertilization (B), or contain the urethra (C). Sperm production occurs in the testes, while the spermatic cord provides the pathway for the sperm to travel from the testes to the urethra for ejaculation.
Which of the following statements is correct?
- A. Follicle stimulating hormone secreted from the hypothalamus stimulates spermatogenesis in the Sertoli cells.
- B. Luteinizing hormone secreted from the hypothalamus stimulates the release of testosterone from the Leydig cells.
- C. Leydig cells secrete testosterone which stimulates spermatogenesis in the Sertoli cells.
- D. Leydig cells secrete inhibin
Correct Answer: C
Rationale: Rationale:
C is correct because Leydig cells in the testes secrete testosterone, which is essential for stimulating spermatogenesis in the Sertoli cells. Testosterone plays a crucial role in the development and maturation of sperm. A is incorrect because follicle stimulating hormone is secreted by the pituitary gland, not the hypothalamus. B is incorrect because luteinizing hormone is secreted by the pituitary gland, not the hypothalamus. D is incorrect because Leydig cells primarily secrete testosterone, not inhibin.
The nurse will plan to teach a 51-yr-old man who is scheduled for an annual physical examination about a(n)
- A. increased risk for testicular cancer.
- B. possible changes in erectile function.
- C. normal decreases in testosterone level.
- D. prostate specific antigen (PSA) testing.
Correct Answer: C
Rationale: The correct answer is C: normal decreases in testosterone level. At the age of 51, it is important to educate the man about the normal age-related decline in testosterone levels, which can affect various aspects of health. This information will help manage expectations and address potential symptoms. Option A is incorrect as testicular cancer risk typically decreases with age. Option B may be a concern but is not the primary focus of education for a routine physical exam. Option D (PSA testing) is more relevant for prostate health, which is not the main focus of education for a 51-year-old man's annual physical exam.
