What is the source and function of HCG?
- A. uterus; cause labor
- B. ovary; stimulates FSH
- C. placenta; inhibits LH
- D. placenta; mimics LH
Correct Answer: D
Rationale: The correct answer is D: placenta; mimics LH.
Rationale:
1. HCG (Human Chorionic Gonadotropin) is produced by the placenta during pregnancy.
2. HCG mimics the action of LH (Luteinizing Hormone) to support the corpus luteum in producing progesterone.
3. This helps maintain the uterine lining and supports the pregnancy.
Summary:
A: Incorrect - Uterus does not produce HCG, and it does not cause labor.
B: Incorrect - Ovary does not produce HCG, and it does not stimulate FSH.
C: Incorrect - Placenta produces HCG, but it does not inhibit LH; instead, it mimics LH's actions.

At the level of the testicle, the straight tubules:
- A. are located inside the lobules;
- B. continue the convoluted seminiferous tubules;
- C. open in the rete testis;
- D. open in the epididymal duct;
Correct Answer: C
Rationale: The correct answer is C because the straight tubules open into the rete testis, which is a network of tubules located at the hilum of the testis. This is where sperm produced in the seminiferous tubules are collected and transported to the epididymis for maturation. The other choices are incorrect because A is not accurate as straight tubules are not located inside the lobules, B is incorrect as straight tubules are a separate structure from the convoluted seminiferous tubules, and D is inaccurate as straight tubules do not open directly into the epididymal duct.
What effect does luteinizing hormone uterine (fallopian) tubes is called the (LH) have on a female?
- A. LH promotes enlargement of
- B. body the female's breasts.
- C. fundus
- D. LH has no effect on a femal
Correct Answer: D
Rationale: Rationale:
1. LH is a hormone released by the pituitary gland.
2. Its main role in females is to trigger ovulation.
3. LH does not directly affect the uterine tubes or breast enlargement.
4. Therefore, the correct answer is D: "LH has no effect on a female."
Summary:
A, B, and C are incorrect because LH does not promote breast enlargement or affect the uterine tubes. The correct answer, D, is supported by the physiological functions of LH in the female reproductive system.
We can state the following about the uterus:
- A. it is made up of corpus and cervix;
- B. the vagina is inserted on the cervix;
- C. the uterine cavity displays a mucous membrane that undergoes cyclical modifications;
- D. it has striated musculature, with longitudinal, radial and circular fibers;
Correct Answer: C
Rationale: Step 1: The uterine cavity displays a mucous membrane that undergoes cyclical modifications due to hormonal changes during the menstrual cycle.
Step 2: This mucous membrane is essential for embryo implantation and plays a crucial role in pregnancy.
Step 3: The cyclical modifications of the mucous membrane are necessary for the shedding of the endometrium during menstruation.
Summary: Choice C is correct because it accurately describes a key function of the uterus related to the menstrual cycle. Choices A, B, and D are incorrect as they do not address the specific function of the uterine cavity and its mucous membrane modifications.
A client is asking the nurse questions about the diagnosis of endometriosis. The nurse teaches the client that endometrial tissue is found outside the uterus and that the major symptom that a client experiences is which of the following?
- A. Pain
- B. Infection
- C. Minimal bleeding
- D. Cramping
Correct Answer: A
Rationale: Pain is the primary symptom associated with endometriosis.
Which structure provides a temporary
- A. seminal gland storage site for immature sperm?
- B. tunica albuginea
- C. ductus deferens
- D. ductus deferens
Correct Answer: A
Rationale: The correct answer is A, seminal gland, which provides a temporary storage site for immature sperm. Seminal glands are responsible for producing seminal fluid which nourishes and protects the sperm. The immature sperm are stored in the seminal gland until they mature. The other choices, B tunica albuginea, is a tough layer surrounding the testes, not involved in sperm storage. C ductus deferens is a tube that transports mature sperm from the epididymis to the urethra, not for storage of immature sperm. D is a duplicate of C, so it is incorrect.
