1. How many arteries are there in an umbilical cord?

• A. Three
• B. One
• C. Two
• D. Four

Correct answer: C

Rationale: There are two arteries in an umbilical cord. The umbilical cord contains two arteries and one vein. Artery carries blood away from the fetus, while the vein returns blood to the fetus. Therefore, choices A, B, and D are incorrect as they do not represent the correct number of arteries in an umbilical cord.

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 is a Carneous Mole defined as?

• A. Occurs when fluids drain from the blood mole, leaving a fresh firm mass.
• B. Occurs when the ovum dies and is expelled.
• C. Occurs when the fetus dies, and the membranes rupture.
• D. Occurs when the fetus survives after a failed abortion attempt.

Correct answer: A

Rationale: A Carneous Mole is defined as when fluids drain from the blood mole, leaving a fresh firm mass. This process leads to the formation of a solid mass resembling tissue. Choice B is incorrect as it describes a different concept known as a missed abortion, where the ovum dies and is expelled. Choice C is incorrect as it describes a situation related to fetal demise and membrane rupture, not specifically the formation of a Carneous Mole. Choice D is incorrect as it refers to a scenario where the fetus survives after a failed abortion attempt, which is distinct from the definition of a Carneous Mole.

4. 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.

5. Amniocentesis deals with patterns of ______ in the amniotic fluid.

• A. Fingers
• B. DNA
• C. Chromosomes
• D. Proteins

Correct answer: C

Rationale: Amniocentesis is a prenatal test that involves examining chromosomes in the amniotic fluid to detect genetic abnormalities. Therefore, the correct answer is 'Chromosomes.' The other choices, such as 'Fingers,' 'DNA,' and 'Proteins,' do not accurately represent what is analyzed during an amniocentesis procedure and are unrelated to the genetic information obtained through this test.
