Testosterone produces negative feedback to:
- A. the anterior pituitary to turn off follicle stimulating hormone secretion
- B. the anterior pituitary to turn off both luteinizing hormone and follicle stimulating hormone secretion
- C. Sertoli cells turn off inhibin secretion
- D. the anterior pituitary to turn off luteinizing hormone secretion
Correct Answer: D
Rationale: Step-by-step rationale:
1. Testosterone inhibits the release of luteinizing hormone (LH) through negative feedback.
2. LH is produced by the anterior pituitary.
3. Therefore, testosterone exerts negative feedback on the anterior pituitary to turn off LH secretion.
4. This maintains hormonal balance in the body.
Summary of other choices:
A. Incorrect because testosterone primarily affects LH secretion, not follicle stimulating hormone (FSH).
B. Incorrect as it inaccurately suggests that testosterone turns off both LH and FSH secretion.
C. Incorrect because Sertoli cells are involved in spermatogenesis, not LH regulation.

A 79-year-old client who has just returned to the surgical unit following a TURP complains of acute abdominal pain caused by bladder spasms. All of these orders are listed on the client's chart. In what order will you accomplish these actions?
- A. Administer acetaminophen/oxycodone 325 mg/5 mg (Percocet) 2 tablets.
- B. Irrigate retention catheter with 30-50 mL of sterile normal saline.
- C. Infuse 500 mL of 5% dextrose in lactated Ringer's solution over 2 hours.
- D. Encourage client's oral fluid intake to at least 2500-3000 mL daily.
Correct Answer: B
Rationale: Irrigating the catheter addresses the potential blockage causing the spasms.
Anterior to the vagina and urethral openings is the
- A. Labia majora
- B. Labia minor
- C. Mons pubis
- D. Cervical sphincter
Correct Answer: A
Rationale: The correct answer is A: Labia majora. The labia majora are located anterior to the vagina and urethral openings, providing protection and support. The labia minora are internal to the labia majora. The mons pubis is the rounded mass of fatty tissue located over the pubic symphysis. Cervical sphincter is not a relevant anatomical structure in this context. Therefore, the labia majora is the correct choice based on its anatomical location and function.
Levels of transcortin are elevated in a pregnant woman. Which of the following laboratory findings would be expected in this patient?
- A. Increased total (protein-bound plus free) plasma cortisol concentration
- B. Increased free (non–protein-bound) plasma cortisol concentration
- C. Decreased total plasma cortisol concentration
- D. Decreased free plasma cortisol concentration
Correct Answer: A
Rationale: Rationale: Elevated levels of transcortin in a pregnant woman lead to an increase in total plasma cortisol concentration. Transcortin binds to cortisol, increasing its total concentration but reducing the amount of free (non-protein-bound) cortisol. Choice A is correct as total cortisol concentration increases due to transcortin binding. Choices B and D are incorrect as free cortisol concentration decreases. Choice C is incorrect as total cortisol concentration is elevated, not decreased.
The hormone testosterone is tubes called seminiferous tubules that produced by the ________ cells of the are found within each ________. testes.
- A. spermatic cord
- B. spermatogonia
- C. testis
- D. oogonia
Correct Answer: B
Rationale: The correct answer is B: spermatogonia. Spermatogonia are the cells within the seminiferous tubules of the testes that give rise to sperm cells. Testosterone is produced by Leydig cells, not spermatogonia. A is incorrect because the spermatic cord does not produce testosterone. C is incorrect as the testis is the overall organ where the seminiferous tubules are located. D is incorrect as oogonia are female germ cells found in the ovaries, not the testes.
When palpating the epididymis, the nurse considers which finding to be abnormal?
- A. The epididymis is located on the posterolateral surface of each testis.
- B. The epididymis feels like a tubular, comma-shaped structure.
- C. The epididymis collapses on palpation.
- D. The epididymis has an irregular, nodular surface.
Correct Answer: D
Rationale: The correct answer is D because an epididymis with an irregular, nodular surface is abnormal and may indicate a pathology such as epididymitis or a tumor. Step 1: Normal epididymis should feel smooth and firm, not irregular. Step 2: Nodular surface suggests a growth or inflammation. Step 3: Abnormal findings should prompt further evaluation. Incorrect choices: A is correct anatomical location, B describes the normal shape, and C collapsing is not a typical finding.
