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 one of the following statements is NOT true about menstruation?

• A. The average amount of menstrual flow is 50 to 90 ml.
• B. The menstrual flow constitutes serous fluid, necrotic slough.
• C. The cycle is influenced by the ovarian hormones Estrogen and progesterone.
• D. The menstrual flow has non-clotting blood.

Correct answer: D

Rationale: The correct answer is D. The statement that menstrual flow has non-clotting blood is incorrect because menstrual blood can indeed clot. Choices A, B, and C are all true statements about menstruation. Choice A reflects the average amount of menstrual flow, choice B describes the components of menstrual flow, and choice C correctly identifies the ovarian hormones that influence the menstrual cycle.

3. To ensure the provision of appropriate services for overcoming infertility barriers to the achievement of reproductive intentions, Integrated Reproductive Health has incorporated a component of:

• A. Infertility
• B. Safe abortions
• C. STIs and HIV
• D. Family Planning

Correct answer: A

Rationale: The correct answer is A: Infertility. Integrated Reproductive Health incorporates a component focused on infertility to address barriers to achieving reproductive intentions. This inclusion is crucial as infertility can be a significant obstacle to reproductive health. Choice B, safe abortions, is incorrect as it is not directly related to overcoming infertility barriers. Choice C, STIs and HIV, while important for reproductive health, is not specifically addressing infertility. Choice D, family planning, although relevant for reproductive health, is not the primary focus when addressing infertility barriers.

4. Which of the following hormones promotes endometrial growth?

• A. LH
• B. FSH
• C. Estrogen
• D. Progesterone

Correct answer: C

Rationale: Estrogen is the hormone responsible for promoting endometrial growth. Estrogen helps thicken the endometrium during the menstrual cycle in preparation for implantation. LH (Choice A) and FSH (Choice B) are involved in regulating the menstrual cycle but do not directly promote endometrial growth. Progesterone (Choice D) is important for maintaining the endometrium after ovulation but is not the primary hormone responsible for promoting its growth.

5. What is amniocentesis used to detect?

• A. Sexually transmitted diseases
• B. Presence of certain genetic disorders
• C. Causes of infertility
• D. Presence of pneumonia germs

Correct answer: B

Rationale: Amniocentesis is a prenatal test used to detect certain genetic disorders in a developing fetus. It involves collecting a small sample of the amniotic fluid surrounding the fetus and analyzing the genetic material present in the cells. This test is not used to detect sexually transmitted diseases, causes of infertility, or the presence of pneumonia germs. Therefore, the correct answer is B.
