The deferent duct (vas deferens):
- A. joins with the seminal vesicle duct and forms the ejaculatory duct;
- B. continues the rete testis;
- C. continues the epididymal duct;
- D. is an extratesticular spermatic duct;
Correct Answer: C
Rationale: Step-by-step rationale for Choice C (Continues the epididymal duct) being the correct answer:
1. The deferent duct, also known as the vas deferens, is a continuation of the epididymal duct.
2. Sperm mature and are stored in the epididymis before passing into the vas deferens.
3. The vas deferens carries sperm from the epididymis to the ejaculatory duct during ejaculation.
Summary:
- Choice A is incorrect because the deferent duct does not join with the seminal vesicle duct to form the ejaculatory duct.
- Choice B is incorrect as the vas deferens does not continue the rete testis.
- Choice D is incorrect as the vas deferens is an intratesticular spermatic duct, not extratesticular.

What structure corresponds to the scrotum in the male?
- A. labia major
- B. labia minor
- C. pudendal cleft
- D. mons pubis
Correct Answer: A
Rationale: The correct answer is A: labia major. The scrotum in males corresponds to the labia major in females as they both serve as protective structures for the reproductive organs. The labia major in females is analogous to the scrotum in males in terms of function and location. The other choices are incorrect because the labia minor (B) is a smaller structure located inside the labia major, the pudendal cleft (C) refers to the space between the labia major and labia minor, and the mons pubis (D) is a rounded, fatty area located over the pubic bone.
Which of the following terms indicate the beginning of the fertile period when gametes are produced and secondary sex characteristics appear?
- A. Teenage
- B. Adolescence
- C. Puberty
- D. Juvenile
Correct Answer: C
Rationale: The correct answer is C: Puberty. Puberty is the stage of development when gametes are produced and secondary sex characteristics appear, marking the beginning of the fertile period. This period typically occurs between the ages of 10 to 14 in females and 12 to 16 in males.
A: Teenage - Incorrect. Teenage refers to the age range between 13 to 19 and does not specifically indicate the onset of gamete production and secondary sex characteristics.
B: Adolescence - Incorrect. Adolescence is a broader term that encompasses the period from childhood to adulthood, including puberty, but it does not specifically indicate the beginning of the fertile period.
D: Juvenile - Incorrect. Juvenile refers to a young organism that has not reached sexual maturity and does not signify the beginning of gamete production and secondary sex characteristics.
An 18-yr-old female patient who has been admitted to the emergency department after a motor vehicle crash is scheduled for chest and abdominal x-rays. Which information may alter the plans for the x-rays?
- A. Report of abdominal pain
- B. Positive result of hCG test
- C. Blood pressure of 172/88 mm Hg
- D. Temperature of 102.1°F (38.9°
Correct Answer: B
Rationale: The correct answer is B: Positive result of hCG test. This may indicate that the patient is pregnant, which would significantly alter the plans for the x-rays due to the potential harm to the fetus from radiation exposure.
A: Report of abdominal pain is a common symptom after a motor vehicle crash and would not directly alter the plans for x-rays.
C: Blood pressure of 172/88 mm Hg could indicate hypertension but would not directly impact the need for chest and abdominal x-rays.
D: Temperature of 102.1°F (38.9°C) could suggest an infection but would not typically change the necessity for x-rays.
With respect to Sertoli cells which of the following statements is incorrect
- A. Nourish developing sperm
- B. receive stimulation by testosterone
- C. phagocytose defective sperm
- D. secrete the hormone inhibin which inhibits luteinizing hormone secretion
Correct Answer: D
Rationale: The correct answer is D because Sertoli cells do secrete inhibin, but it does not inhibit luteinizing hormone secretion. Inhibin actually inhibits follicle-stimulating hormone (FSH) secretion. Sertoli cells support spermatogenesis by nourishing developing sperm (A), they are stimulated by testosterone (B), and they also phagocytose defective sperm (C). Therefore, option D is incorrect as it misrepresents the role of inhibin in the endocrine regulation of the male reproductive system.
After arriving for your shift in the emergency department (ED), you receive change-of-shift report about all of these clients. Which one do you need to assess first?
- A. A 19-year-old client with scrotal swelling and severe pain that has not decreased with elevation of the scrotum.
- B. A 25-year-old client who has a painless indurated lesion on the glans penis.
- C. A 44-year-old client with an elevated temperature, chills, and back pain associated with recurrent prostatitis.
- D. A 77-year-old client with abdominal pain and acute bladder distention.
Correct Answer: A
Rationale: Severe scrotal pain unrelieved by elevation suggests testicular torsion, a urologic emergency.
