Paraurethral (Skene’s) glands secrete
- A. Estrogen
- B. Mucus
- C. Testosterone
- D. Androgens
Correct Answer: B
Rationale: The paraurethral (Skene's) glands are responsible for secreting mucus to facilitate lubrication during sexual arousal. This mucus aids in lubricating the urethra and providing moisture for sexual intercourse. Estrogen (Choice A) is a hormone produced by the ovaries and not directly related to the function of Skene's glands. Testosterone (Choice C) and androgens (Choice D) are male sex hormones and are not involved in the secretion of mucus by Skene's glands. Therefore, the correct answer is B, mucus, as it aligns with the known function of the paraurethral glands.

A 20-year-old woman is not having menstrual cycles. Her plasma progesterone concentration is found to be minimal. What is the explanation for the low level of progesterone?
- A. LH secretion rate is elevated
- B. LH secretion rate is suppressed
- C. FSH secretion rate is suppressed
- D. No corpus luteum is present
Correct Answer: D
Rationale: The correct answer is D: No corpus luteum is present. The corpus luteum is responsible for producing progesterone after ovulation. Without a corpus luteum, progesterone levels will be minimal, leading to a lack of menstrual cycles.
A: If LH secretion rate is elevated, it would lead to increased corpus luteum formation and progesterone production.
B: If LH secretion rate is suppressed, there would be insufficient stimulation for corpus luteum formation and progesterone production.
C: FSH is responsible for follicle development, not progesterone production.
The process of capacitation usually occurs in the _____.
- A. vagina
- B. testis
- C. prostate
- D. epididymis
Correct Answer: A
Rationale: The process of capacitation occurs in the female reproductive tract, specifically in the vagina. Capacitation is essential for sperm to fertilize an egg, where they undergo changes in the female reproductive tract to become more motile and capable of penetrating the egg. The vagina provides the ideal environment for capacitation to take place due to its specific pH, temperature, and components present in the cervical mucus. The other choices (B: testis, C: prostate, D: epididymis) are incorrect as capacitation is a process that occurs in the female reproductive tract, not in the male reproductive organs.
The glands that produce a thick, yellowish secretion which nourishes and activates sperm are the __
- A. bulbo-urethral glands
- B. prostate
- C. seminal glands (vesicles)
- D. ejaculatory duct
Correct Answer: A
Rationale: The correct answer is A: bulbo-urethral glands. These glands produce a thick, yellowish secretion known as pre-ejaculate or Cowper's fluid. It serves to nourish and activate sperm. The other choices are incorrect because:
B: The prostate gland produces a milky fluid that helps with sperm motility.
C: The seminal glands (vesicles) produce a fluid that provides energy for sperm.
D: The ejaculatory duct is a passageway for semen to leave the body, it does not produce any secretions.
Which finding from the nurse’s physical assessment of a 42-yr-old male patient should be reported to the health care provider?
- A. One testis hangs lower than the other.
- B. Genital hair distribution is diamond shaped
- C. Clear discharge is present at the penile meatus.
- D. Inguinal lymph nodes are nonpalpable bilaterally.
Correct Answer: D
Rationale: The correct answer is D because palpable inguinal lymph nodes could indicate an underlying infection or malignancy, requiring further evaluation by the healthcare provider. This finding is concerning and needs attention.
A: One testis hanging lower than the other is a normal variation and does not typically require reporting.
B: Genital hair distribution being diamond-shaped is a common pattern and is not an abnormal finding that necessitates reporting.
C: Clear discharge at the penile meatus could be normal or due to benign conditions such as urethral irritation, so it may not require immediate reporting unless other concerning symptoms are present.
A chancre usually appears on the external genitalia in which of the following condition:
- A. Syphilis
- B. Gonorrhea
- C. Trichomoniasis
- D. Herpes genitalis
Correct Answer: A
Rationale: Rationale: A chancre is a painless ulcer that is characteristic of primary syphilis infection. It usually appears on the external genitalia as a result of Treponema pallidum infection. This is distinct from the other conditions listed: Gonorrhea presents with urethritis and discharge, Trichomoniasis with vaginal discharge and irritation, and Herpes genitalis with painful vesicles or ulcers. Syphilis is the only condition among the choices that typically presents with a chancre on the external genitalia.
