1. The placenta is developed from which part of the trophoblast?

• A. Chorionic Frondosum
• B. Anchoring Villi
• C. Chorionic Laeve
• D. Body Stalk

Correct answer: A

Rationale: The correct answer is A: Chorionic Frondosum. The placenta is developed from the chorionic frondosum part of the trophoblast. This structure gives rise to the fetal part of the placenta. Choices B, C, and D are incorrect. Anchoring Villi are projections from the chorionic plate that attach the placenta to the uterine wall. Chorionic Laeve refers to the smooth chorion that covers the fetal surface of the placenta. The Body Stalk is a structure that connects the early embryo to the trophoblastic pole of the blastocyst.

2. 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.

3. Menopausal women require a diet rich in calcium to prevent osteoporosis. Which one of the following is a source of calcium?

• A. Spinach
• B. Cabbage
• C. Carrots
• D. Rape

Correct answer: A

Rationale: Corrected Rationale: Spinach is a good source of calcium, which is crucial for preventing osteoporosis in menopausal women. Spinach is a leafy green vegetable high in calcium content. While cabbage, carrots, and rape are nutritious, they do not provide as much calcium as spinach does. Therefore, spinach is the correct choice for menopausal women looking to increase their calcium intake.

4. 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.

5. What should be included in the differential diagnosis of ectopic pregnancy?

• A. Inevitable abortion
• B. Dysmenorrhea
• C. Twisted ovarian cyst
• D. Fibroids

Correct answer: C

Rationale: In the differential diagnosis of ectopic pregnancy, conditions such as twisted ovarian cysts should be considered. Twisted ovarian cysts can present with similar symptoms to ectopic pregnancy, making it important to include them in the differential diagnosis. Choices A, B, and D are not typically part of the differential diagnosis of ectopic pregnancy. Inevitable abortion refers to an imminent miscarriage, dysmenorrhea is characterized by painful menstruation, and fibroids are benign growths in the uterus, none of which are directly related to ectopic pregnancy.
