Which hormone is necessary for the growth of endometrial glands, which are important for the sustenance of a growing embryo until its implantation?
- A. Luteinizing hormone (LH)
- B. Testosterone
- C. Progesterone
- D. Inhibin
Correct Answer: C
Rationale: The correct answer is C: Progesterone. Progesterone is necessary for the growth of endometrial glands as it prepares the endometrium for implantation of the embryo. LH is responsible for ovulation, not endometrial gland growth. Testosterone is a male sex hormone and not directly involved in endometrial gland growth. Inhibin regulates FSH secretion, not endometrial gland growth.

The pregnant patient tells the nurse that she has had three pregnancies and two live births to date. How does the nurse record this in the patient’s history?
- A. Gravida 3, para 3
- B. Gravida 3, para 2
- C. Gravida 2, para 3
- D. Gravida 2, para 2
Correct Answer: B
Rationale: Rationale:
1. Gravida refers to the total number of pregnancies, which is 3 in this case.
2. Para refers to the number of live births, which is 2.
3. Therefore, the correct way to record this patient's history is Gravida 3, para 2.
Summary:
A: Incorrect - para should be 2, not 3.
C: Incorrect - gravida should be 3, not 2.
D: Incorrect - gravida should be 3, not 2.

What is the function of the prolactin hormone?
- A. Prolactin promotes the production of milk from elements in the blood.
- B. Prolactin stimulates the development of alveoli.
- C. Prolactin stimulates increased production of tubules and ducts.
- D. Prolactin promotes the growth and development of the breasts' fatty tissue.

A patient with testicular torsion is experiencing which abnormality?
- A. Abnormal dilation and tortuosity of the veins along the spermatic cord
- B. Twisting of the testicle and spermatic cord
- C. A cystic mass filled with sperm and seminal fluid in the epididymis
- D. An accumulation of fluid in the scrotum
Correct Answer: B
Rationale: The correct answer is B: Twisting of the testicle and spermatic cord. Testicular torsion is the twisting of the spermatic cord, leading to decreased blood flow to the testicle. This causes severe pain and swelling. Choices A, C, and D do not accurately describe the specific abnormality seen in testicular torsion. Choice A describes varicocele, choice C describes a spermatocele, and choice D describes hydrocele, which are different conditions altogether.
A “birth control” compound for men has been sought for several decades. Which of the following would provide effective sterility?
- A. Substance that mimics the actions of luteinizing hormone
- B. Substance that blocks the actions of inhibin
- C. Substance that blocks the actions of follicle-stimulating hormone
- D. Substance that mimics the actions of gonadotropin-releasing hormone
Correct Answer: C
Rationale: The correct answer is C: Substance that blocks the actions of follicle-stimulating hormone. By blocking the actions of FSH, sperm production in the testes would be inhibited, leading to effective sterility. FSH plays a crucial role in stimulating sperm production, so blocking its actions would prevent the development of mature sperm.
Explanation for why the other choices are incorrect:
A: Substance that mimics the actions of luteinizing hormone - Mimicking LH would not necessarily lead to effective sterility in men.
B: Substance that blocks the actions of inhibin - Inhibin regulates FSH secretion but blocking it would not directly lead to effective sterility.
D: Substance that mimics the actions of gonadotropin-releasing hormone - Mimicking GnRH would not directly impact sperm production and sterility.
