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.

Which question should the nurse ask when assessing a 60-yr-old patient who has a history of benign prostatic hyperplasia (BPH)?
- A. “Have you noticed any unusual discharge from your penis?”
- B. “Has there been any change in your sex life in the past year?”
- C. “Has there been a decrease in the force of your urinary stream?”
- D. “Have you been experiencing any difficulty in achieving an erection?”
Correct Answer: C
Rationale: The correct question to ask when assessing a 60-yr-old patient with a history of BPH is C: “Has there been a decrease in the force of your urinary stream?” This question is relevant as BPH commonly causes urinary symptoms like weak urinary stream. Asking about unusual discharge (A) is more relevant for assessing sexually transmitted infections. Inquiring about changes in sex life (B) and difficulty achieving an erection (D) are more related to erectile dysfunction, which may not be directly linked to BPH in this context.
The roles of the testicle are:
- A. endocrine gland (to produce sperm cells);
- B. exocrine gland (to secrete androgenic hormones);
- C. spermatogenesis;
- D. generation of semen;
Correct Answer: C
Rationale: Rationale for correct answer (C): The main function of the testicles is spermatogenesis, which is the process of producing sperm cells. This is a crucial role in male reproductive system. Spermatogenesis occurs in the seminiferous tubules of the testes. Other functions like producing androgenic hormones (choice B) are mainly carried out by the Leydig cells in the testes, not the testicles themselves. While the testicles do play a role in semen production (choice D), this is not their primary function. Therefore, the correct answer is C as it directly relates to the main purpose of the testicles in the male reproductive system.
Outermost layer of the uterus is
- A. Peritoneum
- B. Pericardium
- C. Perimetrium
- D. Pericyte
Correct Answer: C
Rationale: The correct answer is C: Perimetrium. The perimetrium is the outermost layer of the uterus and consists of a thin serous layer of connective tissue. This layer provides support and protection to the uterus.
Rationale:
1. Peritoneum (A) is the serous membrane that lines the abdominal cavity, not the outermost layer of the uterus.
2. Pericardium (B) is the membranous sac that surrounds the heart, not related to the uterus.
3. Pericyte (D) is a type of cell found in blood vessels and involved in vascular function, not a layer of the uterus.
In summary, the perimetrium is the correct answer as it is the specific layer that forms the outer covering of the uterus, providing structural support and protection.
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.
