The testicle is located:
- A. inside a muscular pouch;
- B. inside the scrotum;
- C. at the inguinal canal;
- D. inside the abdominal cavity;
Correct Answer: B
Rationale: The correct answer is B: inside the scrotum. The testicles are located outside the abdominal cavity in a structure called the scrotum. This location is essential for temperature regulation as sperm production requires a slightly lower temperature than the body's core. Choices A, C, and D are incorrect as the testicles are not inside a muscular pouch, at the inguinal canal, or inside the abdominal cavity.
Regarding male reproductive system
- A. Hypospodiasis is caused by the failure of urethral groove to close
- B. The connection between tunica vaginalis and abdominal cavity close after the descendant of testis
- C. SRY protein causes the Wolffian duct to regress
- D. Ampulla of fallopian tube is the commonest site for fertilization
Correct Answer: C
Rationale: The correct answer is C because the SRY protein is responsible for causing the regression of the Wolffian duct in male development. This process leads to the formation of male reproductive structures such as the vas deferens. The other choices are incorrect because:
A: Hypospadias is actually caused by the incomplete closure of the urethral groove during development.
B: The connection between the tunica vaginalis and the abdominal cavity closes after the descent of the testis, not before.
D: The ampulla of the fallopian tube is not involved in male reproduction; it is actually the site of fertilization in the female reproductive system.

Before the preovulatory surge in luteinizing hormone, granulosa cells of the follicle secrete which of the following?
- A. Testosterone
- B. Progesterone
- C. Estrogen
- D. Inhibin
Correct Answer: C
Rationale: The correct answer is C: Estrogen. Before the preovulatory surge in luteinizing hormone, granulosa cells of the follicle primarily secrete estrogen. This hormone plays a crucial role in preparing the uterine lining for implantation and regulating the menstrual cycle. Estrogen also helps in the development of secondary sexual characteristics. Testosterone (Choice A) is mainly produced by the theca cells of the follicle. Progesterone (Choice B) is primarily secreted by the corpus luteum after ovulation. Inhibin (Choice D) is secreted by granulosa cells but primarily functions to inhibit follicle-stimulating hormone (FSH) secretion from the anterior pituitary gland.
Which of the following nursing interventions are advised for clients with prostate cancer to avoid an infection related to the home-care of a Foley catheter?
- A. Boil the leg bag regularly in a solution of hot water and vinegar for 15 minutes during the cleaning.
- B. Disinfect several inches of the catheter with alcohol or any other antiseptic agent before the insertion.
- C. Clean the leg bag by using soap and water and then rinse it with a 1:7 solution of vinegar and water.
- D. Open the connections between the leg bag and the catheter only once in 15 days to reduce the risks of microbial entry.
Correct Answer: C
Rationale: Proper cleaning and maintenance of the catheter equipment are crucial to preventing infections.
