Spermatogenesis is regulated by a negative feedback control system in which follicle-stimulating hormone (FSH) stimulates the steps in sperm cell formation. What is the negative feedback signal associated with sperm cell production that inhibits pituitary formation of FSH?

  • A. Testosterone
  • B. Inhibin
  • C. Estrogen
  • D. Luteinizing hormone
Correct Answer: B

Rationale: The correct answer is B: Inhibin. Inhibin is a hormone secreted by the testes in response to high levels of sperm production. Inhibin acts as a negative feedback signal to the pituitary gland, inhibiting the production of follicle-stimulating hormone (FSH). This helps to regulate spermatogenesis by preventing excessive FSH stimulation.

A: Testosterone is not the negative feedback signal for inhibiting FSH production. While testosterone does play a role in regulating spermatogenesis, it does not directly inhibit pituitary FSH production.

C: Estrogen is not involved in the negative feedback control system of spermatogenesis. Estrogen is more closely associated with the female reproductive system.

D: Luteinizing hormone is not the negative feedback signal for inhibiting FSH production. LH is involved in the regulation of testosterone production, not FSH.

While taking a history of a patient with an enlarged prostate, the nurse expects the patient to report which symptom?

  • A. Painful urination with each voiding
  • B. Blood in the urine upon arising
  • C. Waking from sleep to urinate
  • D. Incontinence throughout the day
Correct Answer: C

Rationale: The correct answer is C: Waking from sleep to urinate. This symptom, known as nocturia, is common in patients with an enlarged prostate due to increased pressure on the bladder causing frequent urination at night. This is a classic sign of benign prostatic hyperplasia (BPH). Painful urination (choice A) is more indicative of a urinary tract infection. Blood in the urine (choice B) could suggest other conditions like bladder cancer. Incontinence throughout the day (choice D) is more commonly associated with other urinary issues such as overactive bladder or pelvic floor dysfunction.

Which one of the following is NOT one

  • A. spermatid of the secondary sex characteristics
  • B. primary spermatocyte typical of males?
  • C. secondary spermatocyte
  • D. deepening voice
Correct Answer: A

Rationale: The correct answer is A because a spermatid is a mature male germ cell that arises from the process of spermatogenesis, not a secondary sex characteristic.
- B is incorrect as a primary spermatocyte is indeed typical of males in the process of spermatogenesis.
- C is incorrect as a secondary spermatocyte is an intermediate stage in spermatogenesis.
- D is incorrect as deepening voice is a secondary sex characteristic associated with male puberty.

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 hormone produced by the corpus

  • A. implantation luteum that helps maintain pregnancy
  • B. cleavage is called ________.
  • C. fertilization
  • D. estrogen
Correct Answer: A

Rationale: The correct answer is A. The hormone produced by the corpus luteum that helps maintain pregnancy is progesterone. After ovulation, the ruptured follicle forms the corpus luteum, which secretes progesterone to support the uterine lining for potential implantation. Choice B is incorrect as cleavage refers to early cell divisions in embryo development. Choice C is incorrect as fertilization is the fusion of sperm and egg. Choice D is incorrect as estrogen is primarily produced by the ovaries.

Which of the following is the primary sign of breast cancer?

  • A. A bloody discharge from the nipple
  • B. A dimpling of the skin over the lesion
  • C. A retraction of the nipple
  • D. A painless mass in the breast
Correct Answer: D

Rationale: A painless mass is often the first noticeable sign of breast cancer.
