1. Which hormone is primarily responsible for the development of female secondary sexual characteristics?

• A. Progesterone
• B. Testosterone
• C. Estrogen
• D. Oxytocin

Correct answer: C

Rationale: Estrogen is primarily responsible for the development of female secondary sexual characteristics. Progesterone, while important in the menstrual cycle and pregnancy, is not primarily responsible for secondary sexual characteristics. Testosterone is the primary male sex hormone. Oxytocin is involved in labor, lactation, and social bonding, but not in the development of female secondary sexual characteristics.

2. Incomplete abortion is characterized by:

• A. Heavy bleeding.
• B. Open os.
• C. Severe cramping.
• D. Light bleeding.

Correct answer: B

Rationale: Incomplete abortion is characterized by an open os, which means that the cervix is dilated, allowing for passage of tissue. This condition typically presents with heavy bleeding as parts of the products of conception are expelled. Severe cramping may also be present due to uterine contractions. Therefore, the correct characteristic of incomplete abortion is an open os (Choice B). Choices A, C, and D are incorrect as heavy bleeding and severe cramping are symptoms associated with incomplete abortion, but they do not specifically define it, and light bleeding is not characteristic of incomplete abortion.

3. 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.

4. During a vaginal examination, which of the following statements is true?

• A. Cervical scrapes cytology can be taken in the same setting.
• B. Preferably done after bimanual examination.
• C. The cervix is best visualized with the Crisco's type of spectrum.
• D. During pregnancy, the cervix feels firm like the tip of the nose.

Correct answer: C

Rationale: The correct answer is C. The cervix is best visualized with the Cusco's type of spectrum. This statement is true and important during a vaginal examination. Choice A is incorrect because cervical cytology scrapes can be taken during the same setting as a vaginal examination, not necessarily prior to it. Choice B is incorrect as it states 'after' bimanual examination, which is not the typical sequence. Choice D is incorrect because during pregnancy, the cervix feels soft rather than firm like the tip of the nose.

5. What is the content of the acrosome?

• A. Lipids
• B. Hormones
• C. Digestive enzymes
• D. None of the above

Correct answer: C

Rationale: The correct answer is C: Digestive enzymes. The acrosome is a structure found in sperm cells that contains enzymes used to penetrate the egg during fertilization. Choice A (Lipids) and Choice B (Hormones) are incorrect as the primary content of the acrosome is digestive enzymes, not lipids or hormones. Choice D (None of the above) is incorrect as the acrosome does contain a specific substance, which are digestive enzymes.
