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. Herpes simplex type 2 (HSV-2) does not cause cold sores of the lips:

• A. True.
• B. False.
• C. Depends on the person.
• D. Not enough information.

Correct answer: B

Rationale: Herpes simplex type 2 (HSV-2) typically causes genital herpes, not cold sores on the lips. Cold sores on the lips are commonly caused by herpes simplex type 1 (HSV-1). Therefore, the statement that HSV-2 causes cold sores of the lips is incorrect. Choice B, 'False,' is the correct answer. Choice A is incorrect because HSV-2 does not cause cold sores on the lips. Choice C, 'Depends on the person,' is incorrect as the cause of cold sores is predominantly linked to HSV-1. Choice D, 'Not enough information,' is also incorrect as this information is well-established in medical knowledge.

3. 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.

4. When does missed abortion occur?

• A. The fetus dies and is retained in utero with the placenta and membranes.
• B. All products of conception are expelled with minimal bleeding.
• C. The cervix remains closed, and the products of conception remain in the uterus.
• D. The cervix remains closed, but there is heavy bleeding.

Correct answer: C

Rationale: Missed abortion occurs when the cervix is closed, and the products of conception remain in the uterus. Choice A describes a missed abortion, not choice C. Choice B describes a complete abortion. Choice D describes a threatened abortion, where the cervix remains closed but there is heavy bleeding.

5. What is Carboprost used for?

• A. Affects milk production.
• B. Relieve constriction ring.
• C. Management of post-partum haemorrhage.
• D. Induce labor.

Correct answer: C

Rationale: Carboprost is used in the management of post-partum haemorrhage. This medication helps to reduce excessive bleeding after childbirth. Choices A, B, and D are incorrect. Carboprost does not affect milk production, relieve constriction ring, or induce labor.
