Which of these is not a function of estrogen?
- A. decreases adipose
- B. breast development
- C. increased skin blood vessels
- D. enlarges clitoris

Breast development, increased skin blood vessels, and enlargement of the clitoris are all functions of estrogen. Adipose tissue regulation is influenced by other hormones like insulin and cortisol.

Which hormone is made by the interstitial cells of the testis?
- A. Estrogen
- B. Testosterone
- C. Human chorionic gonadotropin (hCG)
- D. Luteinizing hormone (LH)
Correct Answer: B
Rationale: Certainly. The correct answer is B: Testosterone. Interstitial cells of the testis, also known as Leydig cells, synthesize and secrete testosterone. Testosterone is the primary male sex hormone responsible for the development of male reproductive tissues and characteristics. Estrogen (A) is primarily produced in the ovaries in females. Human chorionic gonadotropin (hCG) (C) is produced by the placenta during pregnancy. Luteinizing hormone (LH) (D) is secreted by the anterior pituitary gland and stimulates the interstitial cells to produce testosterone.
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.
A client diagnosed with a vaginal fistula is at risk for low self-esteem. Which of the following would be an appropriate recommendation for the client?

Which of the following statements relating to the corpus luteum is incorrect.
- A. the corpus luteum contains the zona pellucida
- B. the corpus luteum degrades if fertilization does not take place
- C. the corpus luteum is derived from the Latin word meaning yellow body.
- D. the corpus luteum develops from the remaining follicle after ovulation
Correct Answer: A
Rationale: The correct answer is A because the corpus luteum does not contain the zona pellucida. The zona pellucida is a glycoprotein layer surrounding the oocyte, not the corpus luteum. The other choices are incorrect because B is true - the corpus luteum degrades if fertilization does not occur; C is true - corpus luteum derives from Latin for yellow body; and D is true - the corpus luteum develops from the remaining follicle after ovulation.
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.
