A client with phimosis is not a candidate for surgery. Which of the following suggestions should a nurse give the client?
- A. Apply a skin cream and try retracting the tissue.
- B. Wash under the foreskin daily and seek care if he cannot retract the tissue.
- C. Apply warm soaks to the foreskin.
- D. Take sitz baths regularly until the tissue retracts.
Correct Answer: B
Rationale: Proper hygiene and seeking care if issues persist are important for managing phimosis non-surgically.

Regarding germ cell tumor of testis
- A. Seminoma is the commonest pure testicular germ cell tumor
- B. Serum alph
- C. FP increases in choriocarcinoma
- D. Schiller- Duvall body is the characteristic histological feature seen in yolk sac tumor
Correct Answer: A
Rationale: The correct answer is A: Seminoma is the commonest pure testicular germ cell tumor. Seminoma is indeed the most common pure germ cell tumor of the testis, accounting for about 40-50% of cases. It typically presents in young adult males and has a good prognosis. Seminoma histologically consists of clear cytoplasmic glycogen and distinct cell borders. Choice B is incorrect as it seems to be incomplete. Choice C is incorrect as AFP (alpha-fetoprotein) increases in yolk sac tumors, not choriocarcinoma. Choice D is incorrect as Schiller-Duvall bodies are characteristic of embryonal carcinoma, not yolk sac tumors.
Which diagnostic study is recommended for high-risk clients in addition to mammography?
- A. Breast biopsy
- B. MRI
- C. Ultrasound
- D. CT scan
Correct Answer: B
Rationale: MRI is often recommended for high-risk clients as an additional diagnostic tool.
How many seminiferous tubules are found in each lobule?
- A. 1-3
- B. 50-100
- C. 200-300
- D. 500 or more
Correct Answer: B
Rationale: The correct answer is B (50-100) because each lobule in the testis contains multiple seminiferous tubules where sperm production occurs. The average number of seminiferous tubules per lobule ranges from 50 to 100. This is supported by anatomical studies and research on testicular structure.
Explanation:
A: 1-3 - This is too low as each lobule contains more seminiferous tubules for efficient sperm production.
C: 200-300 - This is too high as it overestimates the number of seminiferous tubules per lobule.
D: 500 or more - This is excessive and not accurate based on scientific findings.
In summary, choice B is correct because it accurately reflects the typical range of seminiferous tubules per lobule, while the other choices either underestimate or overestimate this number.
Menarche is the
- A. first menses
- B. permanent cessation of menses
- C. first sign of sperm production
- D. time of first ovulation
Correct Answer: A
Rationale: The correct answer is A: first menses. Menarche refers to the onset of a girl's first menstrual period, signifying the beginning of her reproductive years. This event marks the maturation of the reproductive system and the ability to conceive. The other choices are incorrect because menarche does not refer to the permanent cessation of menses (choice B), the first sign of sperm production (choice C), or the time of first ovulation (choice D). Menarche specifically pertains to the first menstrual cycle in females, indicating the initiation of their menstrual and reproductive functions.
The gonads produce sex cells, also spermatids into sperm is known as known as ________, ________.
- A. zygotes
- B. mitosis
- C. interstitial cells
- D. spermiogenesis
Correct Answer: D
Rationale: The correct answer is D: spermiogenesis. Spermiogenesis is the process where spermatids mature into sperm cells in the testes. The gonads (testes in males) produce sex cells, but zygotes are formed through fertilization, not spermiogenesis. Mitosis is a type of cell division for growth and repair, not sperm production. Interstitial cells are found in the testes but are responsible for producing testosterone, not the maturation of spermatids into sperm cells. Therefore, option D is the correct choice as it specifically relates to the transformation of spermatids into sperm cells in the testes.
