Which of the following tissues secrete proteolytic enzymes to liquefy semen?
- A. bulbourethral gland
- B. urethra
- C. prostate
- D. testis
Correct Answer: C
Rationale: The correct answer is C: prostate. The prostate gland secretes proteolytic enzymes such as prostate-specific antigen (PSA) to liquefy semen. This aids in sperm mobility and overall fertility. The other choices are incorrect because:
A: bulbourethral gland secretes a clear fluid to lubricate the urethra during sexual arousal.
B: urethra is a passageway for urine and semen but does not secrete proteolytic enzymes.
D: testis produces sperm cells but does not secrete enzymes to liquefy semen.

A client is undergoing sentinel lymph node mapping. A nurse explains that this new technique reduces the likelihood of which
- A. Lymphedema
- B. Excessive scarring
- C. Cellulitis
- D. None of the above
Correct Answer: A
Rationale: Sentinel lymph node mapping helps reduce the risk of lymphedema by limiting the number of lymph nodes removed.
Cowper's gland is another name for:
- A. Prostate gland
- B. Testes
- C. Bulbourethral glands
- D. Preputial glands
Correct Answer: C
Rationale: The correct answer is C: Bulbourethral glands. Cowper's gland is another name for the bulbourethral glands, which are responsible for producing a lubricating fluid that helps neutralize acidity in the urethra before ejaculation. The prostate gland (A) is responsible for producing seminal fluid, the testes (B) are responsible for producing sperm, and the preputial glands (D) are glands found in the foreskin of the penis. Therefore, the bulbourethral glands (C) are the correct answer because they align with the function and location of Cowper's gland.
Which of the following nursing interventions are advised for clients with prostate cancer to avoid an infection related to the home-care of a Foley catheter?
- A. Boil the leg bag regularly in a solution of hot water and vinegar for 15 minutes during the cleaning.
- B. Disinfect several inches of the catheter with alcohol or any other antiseptic agent before the insertion.
- C. Clean the leg bag by using soap and water and then rinse it with a 1:7 solution of vinegar and water.
- D. Open the connections between the leg bag and the catheter only once in 15 days to reduce the risks of microbial entry.
Correct Answer: C
Rationale: Proper cleaning and maintenance of the catheter equipment are crucial to preventing infections.
Foetal portion of placenta includes
- A. Decidua parietalis
- B. Chorion frondosum
- C. Decidua basalis
- D. Anchoring villi
Correct Answer: B
Rationale: The correct answer is B: Chorion frondosum. The foetal portion of the placenta is formed by the chorion frondosum, which consists of the chorionic villi that develop from the trophoblast. These villi are involved in the exchange of nutrients and waste products between the mother and the foetus.
A: Decidua parietalis is the maternal portion of the placenta, not the foetal portion.
C: Decidua basalis is also part of the maternal portion, not the foetal portion.
D: Anchoring villi are structures that help anchor the placenta to the uterine wall, but they are not specific to the foetal portion.
In summary, the correct answer is B because the chorion frondosum is specifically responsible for the foetal part of the placenta, while the other choices refer to maternal components or structures not directly related to the foetal portion.
The ovule that can be fecundated contains:
- A. 22 somatic chromosomes;
- B. 23 autosomes;
- C. a sex chromosome: X or Y;
- D. 11 pairs of somatic chromosomes;
Correct Answer: B
Rationale: The correct answer is B: 23 autosomes. The ovule contains half the number of chromosomes as the typical somatic cell, which is 46 in humans. This is because during meiosis, the number of chromosomes is reduced by half to ensure the correct chromosome number in the offspring. Therefore, the ovule contains 23 chromosomes, which are autosomes (non-sex chromosomes). Choices A, C, and D are incorrect because the ovule does not contain the same number of somatic chromosomes, a sex chromosome, or 11 pairs of somatic chromosomes.
