What phase corresponds with the luteal phase?
- A. Menstrual phase
- B. Follicular phase
- C. Secretory phase
- D. Menstrual phase
Correct Answer: C
Rationale: The luteal phase corresponds with the secretory phase. During the menstrual cycle, the luteal phase follows ovulation and is characterized by the development of the corpus luteum, secreting progesterone to prepare the endometrium for a potential pregnancy. The other choices, menstrual phase (A), follicular phase (B), and the repeated choice of menstrual phase (D) do not align with the luteal phase and its functions.

- A. Femoral arteries
- B. Inguinal arteries
- C. Pudendal arteries
- D. Internal iliac arteries
Correct Answer: C
Rationale: The correct answer is C: Pudendal arteries. The pudendal arteries are responsible for supplying blood to the external genitalia. These arteries specifically provide blood flow to the perineum, including the external genitalia. Choice A, Femoral arteries, are not primarily responsible for supplying blood to the external genitalia. Choice B, Inguinal arteries, do not supply blood directly to the external genitalia. Choice D, Internal iliac arteries, are not the main suppliers of blood to the external genitalia.

The Gravindex test is used to detect Human Chorionic Gonadotrophic hormone (HCG) in:
- A. Urine or whole blood
- B. Amniotic fluid
- C. Saliva
- D. Cervical mucus
Correct Answer: A
Rationale: The correct answer is A: Urine or whole blood. The Gravindex test is designed to detect Human Chorionic Gonadotrophic hormone (HCG) in urine or whole blood samples. HCG is a hormone produced during pregnancy, and its presence in urine or blood can indicate pregnancy. Choices B, C, and D are incorrect as the Gravindex test is not intended to detect HCG in amniotic fluid, saliva, or cervical mucus. These bodily fluids are not typically used for pregnancy testing purposes.
What is one role of the hormone estrogen?
- A. Stimulates the development of the milk-producing tissue.
- B. Stimulates the production of lactoferrin.
- C. Stimulates the development of the nipple and duct system in the breast.
- D. Stimulates the secretion of relaxin.
Correct Answer: A
Rationale: The correct answer is A: Estrogen stimulates the development of the milk-producing tissue in the breast. This hormone is essential in preparing the breast for milk production. Choice B is incorrect because lactoferrin production is not a primary role of estrogen. Choice C is incorrect as estrogen primarily influences the development of the breast tissue rather than specifically the nipple and duct system. Choice D is incorrect because relaxin secretion is not a function typically associated with estrogen.
The structures of the vulva lie ____________ to the vagina.
- A. Posterior
- B. Inferior
- C. Lateral
- D. Superior
Correct Answer: B
Rationale: The correct answer is 'Inferior.' The structures of the vulva are positioned below the vagina, making them inferior. Choice A, 'Posterior,' refers to structures located at the back, not below the vagina. Choice C, 'Lateral,' means to the side, which is not the correct orientation in this context. Choice D, 'Superior,' indicates above, which is the opposite of the correct relationship described in the question.
