The straight tubules in the testis lead into the
- A. Efferent ducts
- B. Afferent ducts
- C. Rete testis
- D. Ductus epididymis
Correct Answer: D
Rationale: The correct answer is D: Ductus epididymis. The straight tubules in the testis lead into the ductus epididymis because the sperm produced in the testis pass through the straight tubules and enter the epididymis for maturation and storage. This is a crucial step in the sperm development process before they are ready for ejaculation.
Rationale:
- A: Efferent ducts are incorrect because they connect the rete testis to the epididymis and are responsible for transporting sperm from the testis.
- B: Afferent ducts are incorrect as they carry sperm from the rete testis to the epididymis.
- C: Rete testis is incorrect as it is a network of tubules where the straight tubules converge and connect to the efferent ducts, not directly to the epididymis.

The epididymis:
- A. is comm
- B. shaped;
- C. is crossed by the deferent duct (vas deferens);
- D. displays tunica albuginea on the inside;
Correct Answer: C
Rationale: Step 1: The epididymis is a structure where sperm mature and are stored.
Step 2: The deferent duct (vas deferens) carries sperm from the epididymis to the urethra.
Step 3: Since the deferent duct crosses the epididymis, choice C is correct.
Summary: Choices A, B, and D are incorrect because they do not accurately describe the anatomical relationship between the epididymis and the deferent duct.
Which of the following suggestions should a nurse give breast-feeding mothers to prevent or eliminate mastitis and breast abscess?

- B. Minimize frequent nursing of the infants.

You are working as a team with an experienced nursing assistant. Considering your clients' needs for frequent assessments, monitoring, and teaching, which client is most appropriate to assign to the nursing assistant?
- A. A 34-year-old client who has just been admitted with epididymitis and an elevated temperature and needs assessment.
- B. A 43-year-old client who needs discharge teaching after having surgery to remove a stage II ovarian cancer.
- C. A 50-year-old client who has orders to ambulate in the hallway 2 days after having an abdominal hysterectomy.
- D. A 79-year-old client who is receiving continuous bladder irrigation after a transurethral resection of the prostate.

A man is taking a number of medications, one of which appears to be interfering with the emission phase of the sexual act. Which of the following medications could cause this problem?
- A. A medication that prolongs the duration of action of nitric oxide
- B. A medication that blocks the smooth muscle receptors for nitric oxide
- C. A medication that increases the release of nitric oxide
- D. A testosterone-like androgen compound
Correct Answer: B
Rationale: The correct answer is B because blocking the smooth muscle receptors for nitric oxide would interfere with vasodilation necessary for an erection during the emission phase of the sexual act. Choice A would actually enhance the effects of nitric oxide, Choice C would increase nitric oxide release which would typically improve sexual function, and Choice D, a testosterone-like androgen compound, would not directly affect the emission phase related to nitric oxide.
The first polar body appears in the:
- A. primary oocyte just before ovulation
- B. primary oocyte after birth
- C. secondary oocyte after fertilization
- D. primary oocyte before birth
Correct Answer: D
Rationale: The correct answer is D because the first polar body is formed during the first meiotic division of the primary oocyte before birth. The primary oocyte undergoes meiosis I to form the secondary oocyte and the first polar body. This process occurs during fetal development, not after birth.
Choice A is incorrect because the primary oocyte completes meiosis I to form the secondary oocyte and the first polar body before ovulation.
Choice B is incorrect because the primary oocyte forms the first polar body before birth, not after birth.
Choice C is incorrect because the first polar body is formed during meiosis I of the primary oocyte, not after fertilization.
