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.

The process of release of ovum from the ovary is termed as
- A. Dessication
- B. Ovulation
- C. Fenestration
- D. Maturation
Correct Answer: B
Rationale: The correct answer is B: Ovulation. Ovulation is the process of the release of the mature egg (ovum) from the ovary. During ovulation, the egg is released into the fallopian tube where it can potentially be fertilized by sperm. Dessication (A) refers to the process of drying out, Fenestration (C) is the creation of an opening or hole, and Maturation (D) is the process of becoming mature. Therefore, the correct term specifically related to the release of the egg from the ovary is ovulation.
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 Fallopian tubes:
- A. are pair muscular-membranous ducts;
- B. are part of the female genital ducts;
- C. are located between ovary and uterus;
- D. capture the ovule released by the ovary;
Correct Answer: C
Rationale: The correct answer is C because the Fallopian tubes are indeed located between the ovary and the uterus. This is essential for the transportation of the released ovum from the ovary to the uterus for possible fertilization. Choice A is incorrect as the Fallopian tubes are not solely muscular-membranous ducts; they have ciliated epithelial cells aiding in the movement of the ovum. Choice B is too broad, as the Fallopian tubes are just one part of the female reproductive system. Choice D is incorrect because the Fallopian tubes do not capture the ovule; rather, they provide a pathway for its transport.
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.
What excess cellular component do spermatids shed to become sperm during spermiogenesis?
- A. DNA
- B. Cytoplasm
- C. Flagellum
- D. Mitochondria
Correct Answer: B
Rationale: During spermiogenesis, spermatids shed excess cytoplasm to become mature sperm. This process helps streamline the sperm structure for efficient motility and fertilization. DNA (choice A) is essential for sperm function and remains within the sperm. The flagellum (choice C) is actually a necessary structure for sperm motility. Mitochondria (choice D) play a crucial role in providing energy for sperm movement. Shedding excess cytoplasm ensures that the mature sperm is streamlined and optimized for its specific functions.
