1. 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.

2. Which of the following are examples of external genitalia?

• A. Mons veneris
• B. Labia majora
• C. Vagina
• D. Cervix

Correct answer: A

Rationale: The correct answer is A: Mons veneris. The mons veneris and labia majora are considered external genitalia as they are visible externally. The vagina and cervix, on the other hand, are internal structures. The vagina is the canal leading from the external genitals to the cervix, which is the lower, narrow portion of the uterus.

3. When does threatened abortion occur?

• A. The patient experiences slight vaginal bleeding through an undilated cervix.
• B. The patient experiences heavy bleeding and cervical dilation.
• C. The patient experiences severe cramping and heavy bleeding.
• D. The patient experiences painless bleeding and an open cervix.

Correct answer: A

Rationale: Threatened abortion occurs when the patient experiences slight vaginal bleeding through an undilated cervix. This is characterized by bleeding without cervical dilation, distinguishing it from inevitable abortion (heavy bleeding and cervical dilation), incomplete abortion (severe cramping and heavy bleeding), and missed abortion (painless bleeding and an open cervix).

4. 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.

5. The Wolffian duct is also known as ____________.

• A. Mesonephric duct
• B. Ejaculatory duct
• C. Major sublingual duct
• D. Cystic duct

Correct answer: A

Rationale: The correct answer is A: Mesonephric duct. The Wolffian duct is indeed also known as the mesonephric duct. This duct plays a vital role in the development of the male reproductive system by carrying sperm from the epididymis to the ejaculatory duct. Choice B, Ejaculatory duct, is incorrect as it refers to a different duct responsible for transporting semen from the vas deferens. Choices C and D, Major sublingual duct and Cystic duct, are unrelated to the Wolffian duct and are not correct answers in this context.
