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.

What is the source and function of HCG?
- A. uterus; cause labor
- B. ovary; stimulates FSH
- C. placenta; inhibits LH
- D. placenta; mimics LH
Correct Answer: D
Rationale: The correct answer is D: placenta; mimics LH.
Rationale:
1. HCG (Human Chorionic Gonadotropin) is produced by the placenta during pregnancy.
2. HCG mimics the action of LH (Luteinizing Hormone) to support the corpus luteum in producing progesterone.
3. This helps maintain the uterine lining and supports the pregnancy.
Summary:
A: Incorrect - Uterus does not produce HCG, and it does not cause labor.
B: Incorrect - Ovary does not produce HCG, and it does not stimulate FSH.
C: Incorrect - Placenta produces HCG, but it does not inhibit LH; instead, it mimics LH's actions.
On inspection of the internal structure of the vagina, the nurse notes a rounded protrusion on the posterior wall of the vagina. How does the nurse document this finding?
- A. Rectocele
- B. Cystocele
- C. Bartholin cyst
- D. Nabothian cyst
Correct Answer: A
Rationale: The correct answer is A: Rectocele. A rectocele is a herniation of the anterior rectal wall into the posterior vaginal wall. The rounded protrusion on the posterior wall of the vagina indicates a rectocele. This finding is documented as a rectocele due to the specific anatomical location and nature of the protrusion.
Summary of other choices:
B: Cystocele - A cystocele is a herniation of the bladder into the anterior vaginal wall, not the posterior wall.
C: Bartholin cyst - Bartholin cyst is a fluid-filled swelling in the Bartholin gland near the vaginal opening, not on the posterior wall.
D: Nabothian cyst - Nabothian cysts occur on the cervix and are not related to protrusions on the posterior wall of the vagina.
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.
Choose the CORRECT match. Animals Fertilization Embryonic development
- A. Dog Internal Oviparity
- B. Duck External Viviparity
- C. Frog External Oviparity
- D. Cat Internal Ovoviviparity
Correct Answer: C
Rationale: The correct match is C: Frog - External Oviparity. Frogs lay eggs externally, and their fertilization and embryonic development occur outside the female's body. This is characteristic of oviparous animals. The other choices are incorrect because:
A: Dog - Internal Oviparity, dogs give birth to live young and do not lay eggs.
B: Duck - External Viviparity, ducks also give birth to live young and do not lay eggs externally.
D: Cat - Internal Ovoviviparity, cats give birth to live young but retain eggs inside their body until they hatch.
Which of the followings is an erectile organ responsible for sexual sensations?
- A. clitoris
- B. Ovary
- C. Cervix
- D. Breast
Correct Answer: A
Rationale: Rationale: The correct answer is A: clitoris. The clitoris is an erectile organ responsible for sexual sensations due to its high concentration of nerve endings. It becomes engorged with blood during arousal, enhancing sensitivity. Ovary (B), Cervix (C), and Breast (D) are not erectile organs and do not directly contribute to sexual sensations. Ovary produces eggs, Cervix is part of the reproductive system, and Breast is a secondary sexual characteristic involved in breastfeeding.
