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. During an ectopic pregnancy, what is the likelihood of a rupture in the ampullary portion of the tube?

• A. Frequent
• B. Uncommon
• C. Occasional
• D. Never

Correct answer: A

Rationale: During an ectopic pregnancy, a rupture in the ampullary portion of the tube is frequent. This is due to the increased pressure within the fallopian tube as the embryo grows, leading to the rupture of the tube. Choices B, C, and D are incorrect as they do not accurately describe the common occurrence of rupture in this specific part of the tube during an ectopic pregnancy.

3. Which of the following is a function of the placenta?

• A. The placenta secretes insulin.
• B. The placenta facilitates the exchange of gases and nutrients between mother and fetus.
• C. The placenta provides immunological protection to the fetus.
• D. The placenta stores fat-soluble vitamins for the fetus.

Correct answer: B

Rationale: The correct answer is B. The placenta serves as a crucial organ during pregnancy, facilitating the exchange of gases (oxygen and carbon dioxide) and nutrients (such as glucose and amino acids) between the mother and the developing fetus. This exchange is vital for the fetus's growth and development. Choices A, C, and D are incorrect. The placenta does not secrete insulin; insulin is produced by the pancreas. While the placenta provides some immune support to the fetus, its main role is not immunological protection. Additionally, storing fat-soluble vitamins is not a primary function of the placenta.

4. What are the Carunculae Myrtiformes?

• A. Tissues between the vagina and the perineum
• B. A component of the clitoral prepuce
• C. The remnants of the torn hymen
• D. Structures that partially close the vaginal introitus

Correct answer: C

Rationale: The Carunculae Myrtiformes are the remnants of the torn hymen. They are not tissues between the vagina and the perineum (Choice A), a part of the clitoral prepuce (Choice B), or structures that partially close the vaginal introitus (Choice D). Understanding the anatomy of the female reproductive system is crucial for healthcare professionals to provide accurate care and information.

5. Which of the following is a common presentation in women with polycystic ovarian syndrome?

• A. Oligomenorrhea, obesity, and hirsutism
• B. Amenorrhea, generalized hair loss, and weight gain
• C. Repeated ectopic pregnancies and chronic pelvic pain
• D. Fatigue, body aches, and menorrhagia

Correct answer: A

Rationale: The correct answer is A: Oligomenorrhea, obesity, and hirsutism. Polycystic ovarian syndrome (PCOS) commonly presents with irregular periods (oligomenorrhea), obesity, and increased hair growth (hirsutism) due to hormonal imbalances. Choice B is incorrect as amenorrhea (absence of periods), generalized hair loss, and weight gain are not typical features of PCOS. Choice C is incorrect as repeated ectopic pregnancies and chronic pelvic pain are not characteristic of PCOS. Choice D is incorrect as fatigue, body aches, and menorrhagia (excessive menstrual bleeding) are not primary symptoms seen in PCOS.
