Sperm are stores in the ___________, ascend into the ___________ prior to ejaculation, and are discharged from the penis through the ____________
- A. seminiferous tubules, prostate gland, vas deferens.
- B. epididymis, vas deferens, urethra
- C. epididymis, epididymis, urethra
- D. epididymis. Prostate gland, urethra
Correct Answer: B
Rationale: The correct answer is B. Sperm are stored in the epididymis, ascend into the vas deferens prior to ejaculation, and are discharged from the penis through the urethra. The epididymis is where sperm mature and are stored. The vas deferens is the duct through which sperm travels from the epididymis to the urethra for ejaculation. The urethra is the final pathway for sperm to exit the body. Choices A, C, and D are incorrect because they do not follow the correct anatomical pathway of sperm from storage to ejaculation.

The tiny female sex cell that unites with male sperm to form a zygote or fertilized egg.
- A. Ovary
- B. Ovum
- C. Gonad
- D. Gamets
Correct Answer: B
Rationale: The correct answer is B: Ovum. The ovum is the mature female sex cell that unites with a male sperm during fertilization to form a zygote. Ovary (A) is the organ that produces eggs but is not the actual female sex cell. Gonad (C) is a general term for reproductive organs, not the specific female sex cell. Gametes (D) refer to both male and female sex cells, so it is a broad term and not the specific female sex cell. The ovum is the only choice that accurately represents the tiny female sex cell involved in fertilization.
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 part of the uterus opens into the vagina?
- A. Urethra
- B. Cervix
- C. Uterine tubes
- D. Inguinal canal
Correct Answer: B
Rationale: The correct answer is B: Cervix. The cervix is the lower part of the uterus that opens into the vagina. It acts as a barrier between the uterus and vagina, and allows for the passage of menstrual flow, sperm, and a baby during childbirth. The other choices are incorrect because the urethra is a tube that connects the bladder to the outside of the body, the uterine tubes are also known as fallopian tubes that connect the ovaries to the uterus, and the inguinal canal is a passage in the abdominal wall.
Infertility could develop when the sperm cells display _____.
- A. a count of 120 million per ml semen
- B. increased acrosomal activity
- C. normal morphology
- D. a count of less than 20 million per ml semen
Correct Answer: D
Rationale: The correct answer is D because a low sperm count (less than 20 million per ml semen) can lead to infertility as it decreases the chances of successful fertilization. A high sperm count (choice A) is actually beneficial for fertility. Increased acrosomal activity (choice B) can enhance fertilization potential. Normal morphology (choice C) refers to the shape and size of sperm, which is important for fertility but not the primary factor in infertility due to low sperm count. Overall, a low sperm count is the most significant factor in infertility.
While you are orienting a new RN to the medical-surgical unit, you observe the orientee accomplishing all of the following actions while caring for a client with severe pelvic inflammatory disease (PID), who has been admitted to the hospital for administration of IV antibiotics. Which one will require that you intervene most quickly?

- C. The new RN positions the client flat in bed while helping her take a bath.

Correct Answer: C
Rationale: Positioning the client flat in bed can exacerbate discomfort and is inappropriate for PID.
