- C. It is used to detect the fertility status of the woman.
- D. It is used to detect early stages of an STD.

Sperm maturation occurs in the
- A. seminiferous tubules
- B. epididymis
- C. vas deferens
- D. urethra
Correct Answer: B
Rationale: The correct answer is B: epididymis. Sperm maturation occurs in the epididymis, a coiled tube located on the posterior surface of the testes. Here, sperm undergo the process of capacitation, gaining the ability to fertilize an egg. The seminiferous tubules (choice A) are responsible for sperm production, not maturation. The vas deferens (choice C) is a duct that carries mature sperm from the epididymis to the urethra, and the urethra (choice D) is a passage for both urine and sperm but not the site of sperm maturation.
Wolffian duct is also known as ____________.
- A. Mesonephric duct
- B. Ejaculatory duct
- C. Major sublingual duct
- D. Cystic duct
Correct Answer: A
Rationale: The correct answer is A: Mesonephric duct. The Wolffian duct is also known as the mesonephric duct because it develops in the embryo to form the male reproductive system. It gives rise to various structures such as the epididymis, vas deferens, and seminal vesicles. The other choices are incorrect because the ejaculatory duct is formed by the union of the vas deferens and seminal vesicle, the major sublingual duct is associated with saliva production, and the cystic duct is part of the biliary system and not related to the male reproductive system.
Which hormone inhibits the release of FSH from the pituitary gland?
- A. Inhibin
- B. Relaxin
- C. GnRH
- D. hCG
Correct Answer: A
Rationale: Rationale:
1. Inhibin is produced by the ovaries and testes in response to FSH stimulation.
2. Inhibin acts as a negative feedback signal to inhibit further FSH release.
3. This mechanism helps regulate the levels of FSH in the body.
Summary:
- Relaxin is a hormone involved in pregnancy and does not directly inhibit FSH release.
- GnRH stimulates FSH release rather than inhibiting it.
- hCG is produced during pregnancy and does not have a direct role in inhibiting FSH secretion.
The nurse explains to a patient being prepared for colposcopy with a cervical biopsy that the procedure
- A. involves dilation of the cervix and biopsy of the tissue lining the uterus.
- B. will take place in a same-day surgery center so that local anesthesia can be used.
- C. requires that the patient have nothing to eat or drink for 6 hours before the procedure.
- D. Is similar to a speculum examination of the cervix and should result in little
Correct Answer: A
Rationale: Step 1: Colposcopy with a cervical biopsy involves visualization of the cervix using a colposcope.
Step 2: The procedure may involve taking a biopsy of abnormal tissue for further evaluation.
Step 3: Dilation of the cervix may be needed to access and obtain a biopsy sample.
Step 4: Biopsy is taken from the tissue lining the cervix, not the uterus.
Step 5: Therefore, option A is correct as it accurately describes the procedure.
Summary: Choice B is incorrect as colposcopy can be performed in an outpatient setting without the need for local anesthesia. Choice C is incorrect as fasting is not typically required for this procedure. Choice D is incorrect as colposcopy is more invasive than a speculum examination.
The testosterone secretion is controlled by:
- A. the FSH;
- B. the LH;
- C. the corticoadrenal;
- D. the negative feedback of posterior pituitary;
Correct Answer: B
Rationale: Step 1: LH (luteinizing hormone) is produced by the pituitary gland and plays a key role in stimulating the Leydig cells in the testes to produce testosterone.
Step 2: Testosterone secretion is directly controlled by the LH through this stimulation.
Step 3: FSH (follicle-stimulating hormone) is involved in sperm production, not testosterone secretion.
Step 4: Corticoadrenal hormones are related to stress response, not testosterone regulation.
Step 5: Negative feedback from the posterior pituitary does not directly control testosterone secretion.
Therefore, the correct answer is B (the LH) as it directly influences testosterone production.
