The distal portion of the male urethra ________. that runs the length of the penis is the epididymis, ductus (vas) ________.
- A. prostatic,Membranous
- B. prostatic urethra
- C. membranous urethra
- D. epididymis, ductus (vas)
Correct Answer: D
Rationale: The correct answer is D because the question is referring to the male urethra, not the epididymis or vas deferens. The distal portion of the male urethra that runs the length of the penis is the membranous urethra and the spongy (penile) urethra. A and B are incorrect as they mention the prostatic urethra, which is not the distal portion that runs the length of the penis. Choice C is incorrect as it only mentions the membranous urethra and does not address the full distal portion.

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.
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 histology of male reproductive system
- A. Leydig cells are found in the seminiferous tubule
- B. Sertoli cells are involved in maturation of spermatids.
- C. The luminal epithelium of efferent ductules is irregular.
- D. Contraction of smooth muscle in vas deferens is stimulated via sympathetic
Correct Answer: C
Rationale: The correct answer is C because the luminal epithelium of efferent ductules is indeed irregular, which helps in absorption and modification of fluid. A, Leydig cells are located outside the seminiferous tubule. B, Sertoli cells provide nourishment and support to developing sperm cells but do not mature spermatids. D, Contraction of smooth muscle in vas deferens is stimulated by the parasympathetic nervous system, not the sympathetic.
Where do the testes originate in a fetus?
- A. scrotal sac
- B. pelvic cavity
- C. abdominal cavity
- D. retroperitoneal space
Correct Answer: C
Rationale: The testes originate in the abdominal cavity in a fetus. During development, they descend into the scrotal sac through the inguinal canal. This process is essential for proper sperm production as the scrotal environment provides optimal temperature for sperm development. The other choices are incorrect because the testes do not initially form in the scrotal sac, pelvic cavity, or retroperitoneal space. The correct sequence of descent from the abdominal cavity to the scrotal sac is crucial for normal reproductive function.
The Fallopian tube is linked to the:
- A. vagina;
- B. uterus;
- C. ovary;
- D. vulva;
Correct Answer: B
Rationale: The correct answer is B: uterus. The Fallopian tube connects the ovaries to the uterus, allowing eggs to travel from the ovaries to the uterus for fertilization. The vagina (A) is not directly connected to the Fallopian tube but serves as the birth canal. The ovary (C) is where eggs are produced and released into the Fallopian tube, not directly linked to it. The vulva (D) is the external part of the female genitalia and is not connected to the Fallopian tube.
