1. 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.

2. The follicular phase is to the __________ as the luteal phase is to the secretory phase.

• A. Postovulatory
• B. Menstrual
• C. Proliferative
• D. Ovulatory

Correct answer: C

Rationale: The correct answer is C: Proliferative. The follicular phase corresponds to the proliferative phase during the menstrual cycle, characterized by the development of ovarian follicles. The luteal phase, on the other hand, corresponds to the secretory phase when the endometrium prepares for implantation. Choices A, B, and D are incorrect because they do not accurately reflect the phases being compared in the question.

3. Which of the following are outcomes of an ectopic pregnancy EXCEPT?

• A. Tubal abortion
• B. Tubal rupture
• C. Intra-tubal bleeding
• D. Secondary abdominal pregnancy

Correct answer: D

Rationale: Ectopic pregnancy occurs when a fertilized egg implants outside the uterus. Common outcomes include tubal abortion (spontaneous termination of ectopic pregnancy within the fallopian tube), tubal rupture (rupture of the fallopian tube leading to internal bleeding), and intra-tubal bleeding. Secondary abdominal pregnancy, on the other hand, is a rare occurrence and not a typical outcome of an ectopic pregnancy. It involves the implantation of a fertilized egg in the peritoneal cavity rather than the uterus.

4. Discuss the anatomical/physiological changes in pregnancy under the following: Haematological system

• A. Blood volume and plasma volume increase, red blood cells increase, erythropoietin levels decrease, and leukocyte count increases.
• B. Blood volume and plasma volume decrease, and red blood cells decrease.
• C. No changes occur in the haematological system during pregnancy.
• D. Platelet count remains constant, and no change in coagulation factors.

Correct answer: A

Rationale: During pregnancy, the haematological system undergoes changes to support the growing fetus. Blood volume and plasma volume increase to accommodate the needs of the developing baby. Red blood cells increase to support the increased oxygen demand. Contrary to the statement, erythropoietin levels actually increase to stimulate red blood cell production. Additionally, leukocyte count increases to help the mother's immune system cope with the changes during pregnancy. Choice B is incorrect as it describes a decrease in blood components, which is not the case in pregnancy. Choice C is incorrect as there are significant changes in the haematological system during pregnancy. Choice D is incorrect as platelet count can fluctuate during pregnancy, and there are changes in coagulation factors to prevent excessive bleeding.

5. What is the triangular space lying between the vaginal and rectal canals?

• A. Pelvic floor
• B. Perineum
• C. Vestibule
• D. Perineal body

Correct answer: B

Rationale: The correct answer is B: Perineum. The perineum is the triangular space located between the vaginal and rectal canals. It is a region containing various muscles, nerves, and blood vessels that support the pelvic floor. Choice A, Pelvic floor, refers to the structure supporting the organs in the pelvic cavity, not the space between the vaginal and rectal canals. Choice C, Vestibule, is the space within the labia minora containing the openings of the urethra and vagina, not the area between the vaginal and rectal canals. Choice D, Perineal body, is a fibromuscular mass in the perineum area but not the space between the vaginal and rectal canals.
