1. What is the role of the corpus luteum during the menstrual cycle?

• A. The corpus luteum produces estrogen to maintain the endometrium.
• B. The corpus luteum produces progesterone to maintain the endometrium.
• C. The corpus luteum produces testosterone to inhibit ovulation.
• D. The corpus luteum has no significant role during the menstrual cycle.

Correct answer: B

Rationale: The correct answer is B: The corpus luteum produces progesterone to maintain the endometrium during the menstrual cycle. This hormone helps prepare the uterine lining for implantation in case fertilization occurs. Choice A is incorrect because estrogen is mainly produced by the developing follicles in the ovaries. Choice C is incorrect as testosterone is produced in smaller amounts by the ovaries and adrenal glands but does not play a significant role in maintaining the endometrium. Choice D is incorrect as the corpus luteum plays a crucial role in producing progesterone to support the endometrium.

2. 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.

3. Amniocentesis, a prenatal diagnostic test used to determine fetal sex, genetic anomalies, and biochemical abnormalities, is based on:

• A. The karyotyping of the amniotic fluid
• B. Chorionic villus sampling
• C. Umbilical cord blood sampling
• D. Ultrasound

Correct answer: A

Rationale: The correct answer is A. Amniocentesis involves the analysis of the fetal cells present in the amniotic fluid, which is extracted from the amniotic sac surrounding the developing fetus. This fluid contains cells shed by the fetus, which can be cultured and analyzed to obtain a karyotype, providing information about the fetal sex, genetic anomalies, and biochemical abnormalities. Choices B, C, and D are incorrect because chorionic villus sampling involves obtaining a sample of the chorionic villi from the placenta, not the amniotic fluid; umbilical cord blood sampling is typically used for other purposes like assessing the baby's blood for infections or genetic disorders; and ultrasound is a diagnostic imaging technique that does not involve the analysis of fetal cells for genetic information.

4. Which one is not a barrier method for birth control?

• A. Diaphragms
• B. Cervical caps
• C. Vaults
• D. Intrauterine Devices (IUDs)

Correct answer: D

Rationale: The correct answer is D, Intrauterine Devices (IUDs). Barrier methods of birth control physically block sperm from reaching the egg. Diaphragms, cervical caps, and vaults are examples of barrier methods as they create a barrier that prevents sperm from reaching the cervix. In contrast, IUDs work by altering the cervical mucus and uterine lining, making it difficult for sperm to reach the egg, but they do not physically block sperm like barrier methods do.

5. In Primary Health care, the concept of accessibility requires that:

• A. Patients should be required to accept one service in order to gain access to another type of service.
• B. A referral network, including transportation, to higher-level facilities should be coupled to PHC services.
• C. Patients' access to services should be contingent on social or cultural backgrounds, age, and marital status.
• D. Patients' access to services should be based on one's educational status.

Correct answer: B

Rationale: In Primary Health care, accessibility entails having a referral network and transportation system in place to link patients to higher-level facilities when needed. Choice A is incorrect because patients should not be required to accept one service to access another. Choice C is incorrect as access to services should not be contingent on social or cultural backgrounds, age, or marital status. Choice D is also incorrect because educational status should not determine patients' access to healthcare services.
