Nokea
What does line “G” point to?
- A. Dartos muscle
- B. Cremaster muscle
- C. Fascia
- D. Tunica albuginea
Correct Answer: B
Rationale: The correct answer is B: Cremaster muscle. Line "G" points to the cremaster muscle because it is the muscle responsible for raising and lowering the testes to regulate their temperature. This muscle is located within the spermatic cord and is crucial for maintaining optimal conditions for sperm production. The other choices are incorrect because:
A: The dartos muscle is responsible for wrinkling the scrotal skin but is not depicted by line "G."
C: Fascia refers to connective tissue and does not match the description of the muscle shown by line "G."
D: The tunica albuginea is a fibrous coat around the testis but is not represented by line "G."

At the level of the testicle, the straight tubules:
- A. are located inside the lobules;
- B. continue the convoluted seminiferous tubules;
- C. open in the rete testis;
- D. open in the epididymal duct;
Correct Answer: C
Rationale: The correct answer is C because the straight tubules open into the rete testis, which is a network of tubules located at the hilum of the testis. This is where sperm produced in the seminiferous tubules are collected and transported to the epididymis for maturation. The other choices are incorrect because A is not accurate as straight tubules are not located inside the lobules, B is incorrect as straight tubules are a separate structure from the convoluted seminiferous tubules, and D is inaccurate as straight tubules do not open directly into the epididymal duct.
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.
The nurse correlates which factor to an increased risk of endometrial cancer in women with early menarche or late menopause?
- A. Total number of ovulatory cycles
- B. Less hormone stimulation
- C. Need for estrogen replacement in these patients
- D. Extended duration of the menstrual cycle in these patients
Correct Answer: A
Rationale: The correct answer is A: Total number of ovulatory cycles. Early menarche and late menopause lead to a longer reproductive period, resulting in more ovulatory cycles. Increased exposure to estrogen due to more ovulatory cycles is a risk factor for endometrial cancer. Choice B is incorrect as more hormone stimulation, not less, contributes to the risk. Choice C is irrelevant as estrogen replacement therapy is not mentioned in the question. Choice D is incorrect as the duration of the menstrual cycle is not directly linked to the increased risk of endometrial cancer in these women.
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.
The female reproductive system includes the following structures:
- A. ovary;
- B. Fallopian tubes;
- C. vagina;
- D. vulva;
Correct Answer: A
Rationale: The correct answer is A: ovary. The female reproductive system includes the ovaries, which are responsible for producing eggs and hormones like estrogen and progesterone. The Fallopian tubes are passageways for eggs to travel from the ovaries to the uterus, not a part of the system itself. The vagina is the birth canal and where sperm enters during intercourse, but it is not a reproductive organ. The vulva includes external genitalia like the labia and clitoris, but it is not a reproductive structure. Therefore, the ovary is the only structure directly involved in the reproductive process.
