What does the umbilical cord contain?
- A. Pluripotent stem cells
- B. Cord blood stem cells
- C. Blood stem cells
- D. None of the above
Correct Answer: B
Rationale: The correct answer is B: Cord blood stem cells. The umbilical cord contains stem cells that are found in cord blood, known as cord blood stem cells. These stem cells have the potential to develop into various types of cells and are used in medical treatments. Pluripotent stem cells are typically found in embryos and have the ability to develop into any type of cell in the body, not specifically in the umbilical cord. Choice C, blood stem cells, is a vague term that does not specifically refer to the stem cells found in the umbilical cord. Choice D is incorrect as the umbilical cord does contain cord blood stem cells.

Discuss the anatomical/physiological changes in pregnancy under the following: Cardiovascular system
- A. The heart is displaced upward and to the left by the enlarging uterus, cardiac capacity increases, and blood pressure declines slightly.
- B. The heart is displaced downward and to the right, and blood pressure increases.
- C. The cardiovascular system remains unchanged during pregnancy.
- D. Cardiovascular changes include increased peripheral resistance and reduced cardiac output.
Correct Answer: A
Rationale: During pregnancy, the cardiovascular system undergoes changes such as the heart being displaced upward and to the left by the enlarging uterus, increased cardiac capacity, and a slight decline in blood pressure. Choice B is incorrect as the heart is displaced upwards, not downwards, and blood pressure typically decreases slightly. Choice C is incorrect as the cardiovascular system does undergo changes during pregnancy. Choice D is incorrect as cardiovascular changes in pregnancy involve increased cardiac output rather than reduced output.
Which of the following hormones promotes endometrial growth?
- A. LH
- B. FSH
- C. Estrogen
- D. Progesterone
Correct Answer: C
Rationale: Estrogen is the hormone responsible for promoting endometrial growth. Estrogen helps thicken the endometrium during the menstrual cycle in preparation for implantation. LH (Choice A) and FSH (Choice B) are involved in regulating the menstrual cycle but do not directly promote endometrial growth. Progesterone (Choice D) is important for maintaining the endometrium after ovulation but is not the primary hormone responsible for promoting its growth.
When does threatened abortion occur?
- A. The patient experiences slight vaginal bleeding through an undilated cervix.
- B. The patient experiences heavy bleeding and cervical dilation.
- C. The patient experiences severe cramping and heavy bleeding.
- D. The patient experiences painless bleeding and an open cervix.
Correct Answer: A
Rationale: Threatened abortion occurs when the patient experiences slight vaginal bleeding through an undilated cervix. This is characterized by bleeding without cervical dilation, distinguishing it from inevitable abortion (heavy bleeding and cervical dilation), incomplete abortion (severe cramping and heavy bleeding), and missed abortion (painless bleeding and an open cervix).
What are the Carunculae Myrtiformes?
- A. Tissues between the vagina and the perineum
- B. A component of the clitoral prepuce
- C. The remnants of the torn hymen
- D. Structures that partially close the vaginal introitus
Correct Answer: C
Rationale: The Carunculae Myrtiformes are the remnants of the torn hymen. They are not tissues between the vagina and the perineum (Choice A), a part of the clitoral prepuce (Choice B), or structures that partially close the vaginal introitus (Choice D). Understanding the anatomy of the female reproductive system is crucial for healthcare professionals to provide accurate care and information.
Which space is present between the bladder and the uterus?
- A. Vesico-uterine pouch
- B. Pubovesical pouch
- C. Retro-uterine pouch
- D. Recto-uterine pouch
Correct Answer: A
Rationale: The correct answer is the vesico-uterine pouch. This space is specifically located between the bladder and the uterus. The pubovesical pouch is incorrect as it refers to the space between the pubic bone and the bladder. The retro-uterine pouch, also known as the pouch of Douglas, is located between the uterus and rectum. The recto-uterine pouch is not a recognized anatomical term, making it an incorrect choice.
