1. Which hormone is detected in pregnancy tests?

• A. Estrogen
• B. Progesterone
• C. Luteinizing hormone (LH)
• D. Human chorionic gonadotropin (hCG)

Correct answer: D

Rationale: Human chorionic gonadotropin (hCG) is the hormone detected in pregnancy tests. During pregnancy, the placenta produces hCG, which can be detected in the urine or blood to confirm pregnancy. Estrogen and progesterone are also essential hormones in pregnancy but are not typically used for pregnancy tests. Luteinizing hormone (LH) is involved in the menstrual cycle and ovulation, not pregnancy.

2. How do contraceptive oral pills help in birth control?

• A. Preventing ovulation
• B. Killing ova
• C. Killing sperms
• D. More than one of the above

Correct answer: A

Rationale: Contraceptive oral pills primarily work by preventing ovulation, which means Choice A is correct. Choices B and C are incorrect because oral contraceptive pills do not kill ova or sperms. Choice D is incorrect because only preventing ovulation is the primary mechanism of action for oral contraceptive pills.

3. Which phase of the menstrual cycle is variable?

• A. Ovulatory
• B. Regenerative
• C. Secretory
• D. Menstrual

Correct answer: B

Rationale: The regenerative phase of the menstrual cycle is the phase in which the endometrium rebuilds after menstruation. This phase can vary in duration from woman to woman and cycle to cycle. Choice A, the ovulatory phase, is not variable as it typically lasts around 24 hours. Choice C, the secretory phase, is also relatively consistent in its duration. Choice D, the menstrual phase, is the shedding of the endometrial lining and usually lasts around 3-7 days.

4. What is the term used to describe the gestational sac surrounded by a blood clot and retained in the tube?

• A. A carneous mole.
• B. A hydatidiform mole.
• C. A vesicular mole.
• D. A chorionic mole.

Correct answer: A

Rationale: The correct answer is A: a carneous mole. A carneous mole occurs when a gestational sac is surrounded by a blood clot and retained in the tube. Choice B, a hydatidiform mole, is incorrect as it refers to an abnormal pregnancy characterized by the presence of hydropic chorionic villi. Choice C, a vesicular mole, is also incorrect as it is another term for a complete hydatidiform mole. Choice D, a chorionic mole, is not a recognized medical term and is therefore incorrect.

5. 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.
