The structure between the uterus and the vagina is the
- A. uterine tube
- B. cervix
- C. vulva
- D. hymen
Correct Answer: B
Rationale: The correct answer is B: cervix. The cervix is the structure between the uterus and the vagina, serving as the lower part of the uterus that connects to the vagina. It plays a crucial role in pregnancy by allowing sperm to enter the uterus and facilitating the passage of menstrual blood.
Rationale:
1. The uterine tube (A) is not the correct answer as it connects the ovaries to the uterus and is not located between the uterus and the vagina.
2. The vulva (C) is the external genitalia and is not the structure between the uterus and the vagina.
3. The hymen (D) is a thin membrane at the opening of the vagina and does not serve as the structure between the uterus and the vagina.

Which of the following statements relating to oestrogen are incorrect
- A. Oestrogen has a positive feedback effect on the hypothalamus
- B. Oestrogen stimulates retention of fluid
- C. Oestrogen stimulates growth of ovaries and follicles
- D. Oestrogen stimulates female body configuration
Correct Answer: A
Rationale: The correct answer is A because oestrogen actually has a negative feedback effect on the hypothalamus. When oestrogen levels rise, it signals the hypothalamus to stop producing gonadotropin-releasing hormone (GnRH), which in turn decreases follicle-stimulating hormone (FSH) and luteinizing hormone (LH) production. This negative feedback loop helps regulate the menstrual cycle. Choices B, C, and D are correct statements about oestrogen. Oestrogen does stimulate retention of fluid, growth of ovaries and follicles, and the development of female body characteristics.
Which of the following is true about placenta?
- A. It produces the hormone hCG.
- B. It stimulates development of the follicle
- C. Implantation site for developing embryo.
- D. It stimulates development of corpus luteum
Correct Answer: A
Rationale: The correct answer is A: It produces the hormone hCG. The placenta is responsible for producing the hormone human chorionic gonadotropin (hCG), which is essential for maintaining pregnancy by supporting the corpus luteum to produce progesterone. This hormone is also detected in pregnancy tests.
Choice B is incorrect because the placenta does not stimulate development of the follicle; rather, it supports the corpus luteum. Choice C is incorrect as the implantation site for the developing embryo is the endometrium of the uterus, not the placenta itself. Choice D is incorrect because the placenta does not stimulate the development of the corpus luteum; instead, it supports its function through hCG production.
What effect does luteinizing hormone (LH) have on a female?
- A. LH promotes enlargement of the female's breasts.
- B. LH has no effect on a female
- C. LH causes secondary sex characteristics to develop in a femal
- D. LH triggers ovulation in a female
Correct Answer: D
Rationale: The correct answer is D: LH triggers ovulation in a female. LH is a hormone released by the pituitary gland that stimulates the release of an egg from the ovary during the menstrual cycle. This process is known as ovulation. It is a crucial step in the reproductive cycle of females.
A: LH does not promote the enlargement of female breasts. Breast growth is primarily regulated by estrogen and progesterone.
B: LH does have a significant effect on females, particularly in the reproductive system.
C: While LH does contribute to the development of secondary sex characteristics in females, its main role is in triggering ovulation.
A 19-yr-old patient calls the school clinic and tells the nurse, “My menstrual period is very heavy this time. I have to change my tampon every 4 hours.” Which action should the nurse take next?
- A. Tell the patient that her flow is not unusually heavy.
- B. Schedule the patient for an appointment later that day.
- C. Ask the patient how heavy her usual menstrual flow is.
- D. Have the patient call again if the heavy flow continues.
Correct Answer: C
Rationale: The correct answer is C: Ask the patient how heavy her usual menstrual flow is. This is the best course of action as it allows the nurse to gather more information about the patient's menstrual history and determine if the current heavy flow is a deviation from her normal pattern. By obtaining information on the patient's usual menstrual flow, the nurse can assess if the current situation warrants further evaluation or if it falls within the range of normal variability.
Choice A is incorrect because dismissing the patient's concern without further assessment may lead to missing a potential issue. Choice B is not the best immediate action as it does not prioritize gathering more information first. Choice D is also not the optimal choice as it does not address the need for more information to assess the situation accurately.
Which hormone is produced throughout a menstrual cycle?
- A. FSH
- B. estrogen
- C. LH
- D. progesterone
Correct Answer: B
Rationale: The correct answer is B: estrogen. Estrogen is produced throughout the menstrual cycle by the ovaries. It plays a key role in regulating the menstrual cycle, promoting the growth of the uterine lining, and preparing the body for ovulation. FSH and LH are involved in stimulating the ovaries to produce estrogen and progesterone, respectively. Progesterone is mainly produced in the second half of the menstrual cycle, after ovulation, to support pregnancy. Therefore, estrogen is the hormone that is produced consistently throughout the menstrual cycle, making it the correct answer.
