Nokea
Which cells secrete testosterone?
- A. Sertoli cells
- B. Spermatogenic cells
- C. Leydig cells
- D. Oogonia
Correct Answer: C
Rationale: Step-by-step rationale:
1. Leydig cells are located in the testes and are responsible for secreting testosterone.
2. Testosterone is a male sex hormone crucial for regulating various functions in the body.
3. Sertoli cells provide support for sperm development, not testosterone secretion.
4. Spermatogenic cells are involved in sperm production, not testosterone secretion.
5. Oogonia are female germ cells, not involved in testosterone secretion.
Summary:
Choice C (Leydig cells) is correct because they are the specific cells in the testes responsible for secreting testosterone. Choices A, B, and D are incorrect as they are associated with other functions related to reproduction and are not involved in testosterone secretion.

Circular movement around an axis is known as ___________________.
- A. Dorsiflexion
- B. Rotation
- C. Extension
- D. Pronation
Correct Answer: B
Rationale: The correct answer is B: Rotation. Circular movement around an axis is described as rotation. This movement involves turning or spinning around a fixed point. Dorsiflexion (A) is the movement of bringing the top of the foot towards the shin. Extension (C) refers to straightening or increasing the angle of a joint. Pronation (D) is the inward rotation of the forearm or foot. Rotation (B) specifically signifies movement around an axis, making it the most appropriate choice for circular movement.
The endocrine role of the testicle:
- A. occurs at the level of the interstitial cells;
- B. consists in the secretion of androgenic hormones;
- C. consists in the secretion of testosterone;
- D. determines the maturation of the sex organs;
Correct Answer: C
Rationale: The correct answer is C because the endocrine role of the testicle primarily involves the secretion of testosterone. Testosterone is the main androgenic hormone produced by the testicles, which plays a crucial role in various physiological functions such as the development of male reproductive organs, sperm production, and secondary sexual characteristics.
Choice A is incorrect because while interstitial cells (Leydig cells) are involved in the production of testosterone, the endocrine role of the testicle is not limited to these cells alone.
Choice B is incorrect as it is too general. While androgenic hormones are indeed secreted by the testicles, testosterone specifically is the main androgenic hormone produced by them.
Choice D is incorrect as the maturation of sex organs is primarily regulated by the action of testosterone but is not the sole endocrine role of the testicle.
Inhibin is
- A. is secreted by Sertoli cells to inhibit follicle stimulation hormone from the anterior pituitary.
- B. is secreted by the anterior pituitary to inhibit testosterone secretion.
- C. is secreted by Sertoli cells to inhibit testosterone secretion
- D. is secreted Leydig cells to inhibit Sertoli cells
Correct Answer: A
Rationale: Inhibin is secreted by Sertoli cells to inhibit follicle stimulating hormone (FSH) from the anterior pituitary. This is the correct answer because inhibin acts as a negative feedback mechanism to regulate FSH levels in the body. Sertoli cells are specifically involved in spermatogenesis and play a crucial role in regulating FSH secretion through inhibin. Choices B, C, and D are incorrect because inhibin does not inhibit testosterone secretion or act on Leydig cells. It specifically targets FSH secretion to regulate the process of spermatogenesis.
Complications of salpingitis include:
- A. Pyosalpinx
- B. Peritonitis
- C. Endometriosis
- D. Infertility
Correct Answer: A
Rationale: The correct answer is A: Pyosalpinx. Salpingitis is inflammation of the fallopian tubes, which can lead to the accumulation of pus within the tube, known as pyosalpinx. This is a common complication of salpingitis due to the infection causing the tubes to become blocked and filled with pus. Peritonitis (B) is inflammation of the peritoneum, not directly related to salpingitis. Endometriosis (C) is a separate condition where endometrial tissue grows outside the uterus. Infertility (D) can be a complication of salpingitis, but pyosalpinx is a more direct and immediate consequence.
A client has been advised to use a pessary to provide support to the uterus. The nurse educates the client about pessary management and the precautions related to its use. In which of the following situations should the client report to the physician?
- A. Regarding a Pap test of the client
- B. Regarding the maintenance of a pessary
- C. When a white or yellow discharge from the vagina develops
- D. Regarding a culture and sensitivity test of vagina
Correct Answer: C
Rationale: Abnormal discharge can indicate infection or other complications requiring medical attention.
