The target of ICSH is the _____.
- A. prostate
- B. seminiferous tubule
- C. interstitial cells
- D. seminal vesicle
Correct Answer: C
Rationale: Step 1: ICSH stands for interstitial cell-stimulating hormone.
Step 2: Interstitial cells are found in the testes and produce testosterone.
Step 3: ICSH targets these interstitial cells to stimulate testosterone production.
Step 4: Therefore, the correct answer is C: interstitial cells.
Summary: A, B, and D are incorrect as ICSH does not target the prostate, seminiferous tubule, or seminal vesicle.

Why is milk produced only after delivery, not before?
- A. Levels of luteinizing hormone and follicle-stimulating hormone are too low during pregnancy to support milk production
- B. High levels of progesterone and estrogen during pregnancy suppress milk production
- C. The alveolar cells of the breast do not reach maturity until after delivery
- D. High levels of oxytocin are required for milk production to begin, and oxytocin is not secreted until the baby stimulates the nipple
Correct Answer: B
Rationale: Correct Answer: B - High levels of progesterone and estrogen during pregnancy suppress milk production.
Rationale:
1. Progesterone and estrogen levels are high during pregnancy to maintain the uterine lining and support fetal development.
2. These hormones inhibit the action of prolactin, the hormone responsible for milk production.
3. As a result, the mammary glands are prevented from producing milk until after delivery when progesterone and estrogen levels drop.
4. Once these hormone levels decrease, prolactin can initiate milk production in response to the baby's demand for feeding.
Summary of other choices:
A: Levels of luteinizing hormone and follicle-stimulating hormone do not directly impact milk production during pregnancy.
C: Alveolar cells of the breast may have some developmental changes during pregnancy, but it is not the primary reason for milk production post-delivery.
D: Oxytocin is involved in milk ejection, not milk production, and its release is
The testicle secrets the following hormones:
- A. androgenic;
- B. progesterone;
- C. testosterone;
- D. progesterone
Correct Answer: C
Rationale: Step 1: The testicles are primarily responsible for producing male sex hormones.
Step 2: Testosterone is the main male sex hormone secreted by the testes.
Step 3: Testosterone is an androgenic hormone responsible for male characteristics.
Step 4: Progesterone is a female sex hormone, not primarily secreted by the testicles.
Step 5: Therefore, the correct answer is C (testosterone).
The fructose in semen is secreted by
- A. the epididymis.
- B. the seminiferous tubules.
- C. the seminal vesicles.
- D. the prostate glands.
Correct Answer: C
Rationale: The correct answer is C, the seminal vesicles. Seminal vesicles secrete fructose in semen to provide energy for sperm motility. This process occurs after sperm leave the epididymis and seminiferous tubules, ruling out choices A and B. The prostate glands contribute to the alkaline fluid in semen, not fructose, eliminating choice D. Therefore, choice C is correct due to its role in providing energy for sperm function.
While giving a history, a patient reports having a weak urinary stream and feeling that his bladder is not empty after urination. Based on these data, what finding does the nurse anticipate upon examination?
- A. An enlarged prostate gland palpated on the anterior wall of the rectum
- B. An indirect hernia palpated through the inguinal ring when the patient coughs
- C. The foreskin of the penis cannot be returned to position after retraction behind the glans
- D. A nodular prostate gland palpated on the posterior wall of the rectum
Correct Answer: A
Rationale: The correct answer is A: An enlarged prostate gland palpated on the anterior wall of the rectum. In this case, the patient's weak urinary stream and feeling of incomplete bladder emptying are classic symptoms of benign prostatic hyperplasia (BPH). During a rectal examination, an enlarged prostate gland can be felt as a smooth, rubbery, and symmetrically enlarged mass on the anterior wall of the rectum. This finding correlates with the patient's urinary symptoms, indicating obstruction of the urethra by the enlarged prostate.
Choice B is incorrect because an indirect hernia is not typically associated with urinary symptoms. Choice C is incorrect as it describes paraphimosis, a condition where the foreskin cannot be returned to its original position. Choice D is incorrect as a nodular prostate gland palpated on the posterior wall of the rectum is more characteristic of prostate cancer rather than BPH, which is typically felt on the anterior wall.
A client is having a hysterosalpingogram. What action by the nurse is most important?
- A. Assist the client in sitting up after the procedure
- B. Provide the client with a pad to avoid dye stains on the clothes.
- C. Teach her to take all antibiotics prescribed until finished
- D. Inform the client that the procedure may cause shoulder pain.
Correct Answer: A
Rationale: The correct answer is A: Assist the client in sitting up after the procedure. This is important to prevent complications like vasovagal response or fainting due to sudden positional changes. Sitting up slowly helps stabilize blood pressure and prevent dizziness.
B: Providing a pad for dye stains is not the most important action as it is a minor concern compared to client safety post-procedure.
C: Taking antibiotics has no direct relevance to the hysterosalpingogram procedure, so it is not the most important action.
D: Informing the client about potential shoulder pain is helpful, but ensuring immediate safety by assisting the client in sitting up takes precedence.
